High Speed Machining (hsm) [ Definitive Guide ]

What is High Speed Machining (HSM)?

High speed machining (HSM)–also called trochoidal milling, adaptive clearing, volumill, and more–is a milling technique that can increase material removal rates, reduce cycle time, and increase Jasa Machining tool life.

This video from my CNC Chef series for Cutting Tool Engineering Magazine gives a quick What is High Speed Machining (HSM) intro:

There are many definitions for High Speed Machining (HSM). MMSOnline uses the tagline “Achieving high metal removal rates with quick milling passes” for the HSM zone on their site. Another very high tech definition of HSM is “Machining at the Resonant Frequency of the Machine,” which goes to HSM techniques for selecting spindle speeds that minimize chatter. You’d think that the “High Speed” part of HSM would emphasize faster spindle speeds (Sandvik says HSM begins at 18000 rpm), but that interpretation is not universal as various shops discovered HSM techniques can work well even on slower milling spindles. Others argue that HSM is all about high material removal rates and leaving a surface finish good enough to call finished in one pass.

One of the things that got people thinking about HSM was the discovery that after a certain point, increasing spindle speed actually reduces the heat in the cut:

This amazing chart is from Dr Herbert Schulz’s, “History of High Speed Machining.”

The dotted lines represent temperatures at various surface speeds measured in m/min. Here is the US, we’re more used to SFM.  Want to understand Surface Speed, SFM, and how do we get from SFM to RPM on the spindle?  Jasa Machining Medan If you’re not familiar, it’s simple stuff and the link will explain.

Note that all of the materials go steadily up and then eventually start dipping back down again as surface speed increases. Somehow, high speed machining causes temperatures decrease beyond a certain spindle rpm!

This chart is in meters/minute, so multiply the values by about 3 to get to SFM. For aluminum, we have a pretty good dip by the time we’re hitting 1000 SFM, for example. In fact, it’s temperature is more equivalent to less than 300 SFM on the other side of the aluminum curve–that’s nothing for aluminum. Heck, if we have a fast enough milling spindle, there’s even room to run HSS faster and get lower temperatures (you’ll note various cutter materials critical temperatures are also marked off–stay below the line for your cutter!).

Steel and cast iron taper down more gently than aluminum, but the effect is still alive and well. Yes Virginia, there surely is some strange behavior when you start in with that HSM stuff!

The same research showed that cutting forces also come down, and that’s at least one reason why the temperatures drop, and why for HSM machining in the right rpm ranges, you can achive high MRR’s with lower cutting forces.

Sidebar: Coating Activation Temperature, Shock Cooling, and Turning Off the Coolant

While we’re on the subject of temperature, sometimes a little heat is important. Certain coatings, such as TiAlN, require a minimum “activation” temperature. At that temperature, their chemical composition changes, the coating is “activated” and it is only then that the coating is doing its job of protecting the cutter.

The combination of a desire to activate the coating and the desire to avoid shock cooling delicate carbide (which causes it to crack and splinter) is why we may see a recommendation from the tooling manufacturer to turn of the coolant even when running at very high spindle speeds common for High Speed Machining.High Speed Machining Techniques

Datron’s M8 Cube uses a high speed spindle and high speed machining techniques to achieve maximum productivity…

Whatever your pet definition of HSM may be, I like to look at HSM machining as a collection of techniques that “grew up” together in various aerospace machining operations such as Boeing’s. It initially involved very high speed spindles but many of these techniques have since turned out to be applicable even for lower speed milling spindles.

These techniques are so useful that many CAM Programs include HSM Toolpaths that make it easy to employ HSM on any job.

Let’s list off some of these techniques:

– HSM prefers to combine roughing and finishing passes. This is really only possible with higher speed spindles, because lower speeds just don’t produce the surface finish.  The potential to skip the finish pass will also vary with the CAM package.  Some HSM algorithms are smoother than others.  If you’re trying to get by with a slower spindle, you’ll have to split into the more traditional roughing and finishing passes. For the finishing pass, use tooling with as many flutes as possible. Finishing assumes all the inside corners have been roughed out, so there will be plenty of chip clearance available. The more flutes you have, the faster you can feed through the work for a given chip load. Hence, productivity goes up. The only reason to use fewer flutes is to improve chip clearance.

– HSM prefers smaller tooling that moves faster to very large slow moving tooling designed for “hogging”. The smaller tooling saves on tool changes and makes it easier to achieve the ideal of eliminating the need for separate roughing and finishing passes.

– To maximize tool life, take advantage of relatively low cut width: 10-15% of tool diameter down to as little as lima% depending on where the sweet spot is for your milling spindle’s max rpm and the SFM your tool can handle in the material. These low radial depths allow the tool better chip clearance and time to cool down in air, allowing for much higher productivity especially on harder materials. See the article on taking heat out of the cut for some idea of how this works. With low cut width, increase the cut depth. This allows more of the cutter’s flute to come into play instead of just wearing out the bottom of the endmill.  Choosing the best cut width for optimum material removal is not an easy task.  The rules of thumb available can be far off the mark.  For best results, you want a Feeds and Speeds Calculator that’s capable of optimizing HSM cutting parameters like our G-Wizard Calculator.

– Higher MRR’s (and shorter cycle times) typically require a little more Cut Width.  Think of Tool Life more in terms of how many cubic inches of material can be removed with the tool rather than how many minutes it can run and you will quickly see that These wider Cut Widths make better economic sense.  Some testing is in order to find your balance.

– When spindle speed is a limiting factor, consider a high feed endmill. High feed endmills maximize axial chip thinning and allow much higher feedrates. Another popular roughing strategy when you don’t have as much spindle speed as you’d like are as much machine rigidity is plunge roughing.

– Use CAM toolpath strategies that avoid the “Tyranny of the Corner” (see below for more on cutters). Such strategies include constant tool engagement angle strategies such as Volumill or Adaptive Clearing, Trochoidal Milling, and Slicing or Peeling of Corners.

– Since true HSM spindles offer a much broader range of rpms than conventional spindles, HSM often emphasizes choosing spindle speeds that maximize stable milling zones were chatter is much less likely. The same anti-chatter principles can be applied to lower spindle speeds, you simply have less rpm territory in which to find a stable zone that maximizes productivity. See our article on chatter for more on stable milling zones and the role of spindle rpm in chatter.

– HSM is going to involve a lot more movement on your CNC machine to implement its swirling toolpaths.  That Jasa Machining Medan puts greater demands on your machine’s controller.  Many controllers require an extra cost HSM feature to be enabled before they can get the full benefit of HSM toolpaths.

So there you have a small arsenal of strategies to choose from for increasing your productivity using ideas learned in the HSM world. Let’s drill down a bit more on some of them.Radial Chip Thinning when High Speed Machining

One of the first issues you will encounter when attempting to practice HSM with its low width of cut (or stepover) is radial chip thinning. We’ve written a detailed article on the subject, but for a quick overview, consider the following diagram:

Milling (machining) – Wikipedia

A tiga-axJasa Machining Medan is clone of a Bridgeport-style vertical milling machine

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances.

Milling can be done with a wide range of machine tools. The original group of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into machining centers: milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant Jasa Machining Medan systems, and enclosures. Milling centers are generally classified as vertical machining centers (VMCs) or horizontal machining centers (HMCs).

The integration of milling into turning environments, and vice versa, began with live tooling for lathes and the occasional use of mills for turning operations. This led to a new group of machine tools, multitasking machines (MTMs), which are purpose-built to facilitate milling and turning within the same work envelope.Process[edit]

Face milling process (cutter rotation axis is vertical – 0° inclination relative to tool axis)

Milling is a cutting process that uses a milling cutter to remove material from the surface of a work piece. The milling cutter is a rotary cutting tool, often with multiple cutting points. As opposed to drilling, where the tool is advanced along its rotation axis, the cutter in milling is usually moved perpendicular to its axis so that cutting occurs on the circumference of the cutter. As the milling cutter enters the work piece, the cutting edges (flutes or teeth) of the tool repeatedly cut into and exit from the material, shaving off chips (swarf) from the work piece with each pass. The cutting action is shear deformation; material is pushed off the work piece in tiny clumps that hang together to a greater or lesser extent (depending on the material) to form chips. This makes metal cutting somewhat different (in its mechanics) from slicing softer materials with a blade.

The milling process removes material by performing many separate, small cuts. This is accomplished by using a cutter with many teeth, spinning the cutter at high speed, or advancing the material through the cutter slowly; most often it is some combination of these three approaches. The speeds and feeds used are varied to suit a combination of variables. The speed at which the piece advances through the cutter is called feed rate, or just feed; it is most often measured as distance per time (inches per minute [in/min or ipm] or millimeters per minute [mm/min]), although distance per revolution or per cutter tooth are also sometimes used.

There are two major classes of milling process:In face milling, the cutting action occurs primarily at the end corners of the milling cutter. Face milling is used to cut flat surfaces (faces) into the work piece, or to cut flat-bottomed cavities.In peripheral milling, the cutting action occurs primarily along the circumference of the cutter, so that the cross section of the milled surface ends up receiving the shape of the cutter. In this case the blades of the cutter can be seen as scooping out material from the work piece. Peripheral milling is well suited to the cutting of deep slots, threads, and gear teeth.Milling cutters[edit]

Many different types of cutting tools are used in the milling process. Milling cutters such as end mills may have cutting surfaces across their Jasa Machining entire end surface, so that they can be drilled into the work piece (plunging). Milling cutters may also have extended cutting surfaces on their sides to allow for peripheral milling. Tools optimized for face milling tend to have only small cutters at their end corners.

The cutting surfaces of a milling cutter are generally made of a hard and temperature-resistant material, so that they wear slowly. A low cost cutter may have surfaces made of high speed steel. More expensive but slower-wearing materials include cemented carbide. Thin film coatings may be applied to decrease friction or further increase hardness.

There are cutting tools typically used in milling machines or machining centers to perform milling operations (and occasionally in other machine tools). They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutter’s shape (e.g., a form tool such as a hobbing cutter).

A diagram of revolution ridges on a surface milled by the side of the cutter, showing the position of the cutter for each cutting pass and how it corresponds with the ridges (cutter rotation axis is perpendicular to image plane)

As material passes through the cutting area of a milling machine, the blades of the cutter take swarfs of material at regular intervals. Surfaces cut by the side of the cutter (as in peripheral milling) therefore always contain regular ridges. The distance between ridges and the height of the ridges depend on the feed rate, number of cutting surfaces, the cutter diameter. With a narrow cutter and rapid feed rate, these revolution ridges can be significant variations in the surface finish.

Trochoidal marks, characteristic of face milling.

The face milling process can in principle produce very flat surfaces. However, in practice the result always shows visible trochoidal marks following the motion of points on the cutter’s end face. These revolution marks give the characteristic finish of a face milled surface. Revolution marks can have significant roughness depending on factors such as flatness of the cutter’s end face and the degree of perpendicularity between the cutter’s rotation axis and feed direction. Often a final pass with a slow feed rate is used to improve the surface finish after the bulk of the material has been removed. In a precise face milling operation, the revolution marks will only be microscopic scratches due to imperfections in the cutting edge.

Heavy gang milling of milling machine tables

Gang milling refers to the use of two or more milling cutters mounted on the same arbor (that is, ganged) in a horizontal-milling setup. All of the cutters may perform the same type of operation, or each cutter may perform a different type of operation. For example, if several workpieces need a slot, a flat surface, and an angular groove, a good method to cutthese (within a non-CNC context) would be gang milling. All the completed workpieces would be the same, and milling time per piece would be minimized.[lima]

Gang milling was especially important before the CNC era, because for duplicate part production, it was a substantial efficiency improvement over manual-milling one feature at an operation, then changing machines (or changing setup of the same machine) to cut the next op. Today, CNC mills with automatic tool change and 4- or lima-axis control obviate gang-milling practice to a large extent.Equipment[edit]

Milling is performed with a milling cutter in various forms, held in a collett or similar which, in turn, is held in the spindle of a milling machine.Types and nomenclature[edit]

Mill orientation is the primary classification for milling machines. The two basic configurations are vertical and horizontal – referring to the orientation of the rotating spindle upon which the cutter is mounted. However, there are alternative classifications according to method of control, size, purpose and power source.Mill orientation[edit]Vertical[edit]

Vertical milling machine. 1: milling cutter 2: spindle 3: top slide or overarm 4: column 5: table 6: Y-axis slide 7: knee 8: base

In the vertical milling machine the spindle axis is vertically oriented. Milling cutters are held in the spindle and rotate on its axis. The spindle can generally be lowered (or the table can be raised, giving the same relative effect of bringing the cutter closer or deeper into the work), allowing plunge cuts and drilling. There are two subcategories of vertical mills: the bed mill and the turret mill.A turret mill has a fixed spindle and the table is moved both perpendicular and parallel to the spindle axis to accomplish cutting.Some turret mills have a quill which allows the milling cutter (or a drill) to be raised and lowered in a manner similar to a drill press.This provides two methods of cutting in the vertical (Z) direction:by raising or lowering the quill, and by moving the knee.In the bed mill, however, the table moves only perpendicular to the spindle’s axis, while the spindle itself moves parallel to its own axis.

Shafts are mechanical parts that transmit motion, torque, or bending moments. Generally round metal rods, each segment can have different diameters.Motor shaft machining, stainless steel shaft machining, long shaft parts, precision shaft machining, small shaft machining, gear shaft machining, step shaft machining.

Technology

The product structure of the shaft is different. The shaft can be divided into  a stepped shaft, a tapered mandrel, an optical shaft, a hollow shaft, a crankshaft, a camshaft, an eccentric shaft, various screw shafts, and the like.It is mainly used to support transmission parts, transmit torque and bear load. Shaft parts are rotating parts, whose length is greater than the diameter, generally consisting of the outer cylindrical surface, conical surface, inner Jasa Machining bore and threads of the concentric shaft and the corresponding end face. According to different structural shapes, shaft parts can be divided into optical axis, stepped shaft, hollow shaft and crankshaft.

Shafts with an aspect ratio of less than lima are called minor axes, and those with diameters greater than 20 are called elongated shafts, with most of the axes in between.

Material

There are many types of shaft materials, and the selection is mainly based on the shaft strength, stiffness, wear resistance and other requirements, as well as the heat treatment method used to achieve these requirements, while taking into account the manufacturing process to be selected, and strive to economic and reasonable.

The common materials for shafts are high-quality carbon Jasa Machining Medan steels 35, 45, and 50. The most commonly used steels are 45 and 40Cr steels. For shafts with smaller loads, ordinary carbon steels such as Q235 or Q275 are also commonly used. For the shafts that require greater force, shaft size and weight are limited, and there are certain special requirements, alloy steel can be used, commonly used 40Cr, 40MnB, 40CrNi and so on. The material of the shaft is mainly carbon steel and alloy steel. Most of the steel shaft blanks use rolled steel and forgings, while others use direct round steel.

Ductile cast iron and some high-strength cast irons are easy to cast into complex shapes due to their good casting properties, as well as good vibration damping performance. Low sensitivity to Jasa Machining Medan stress concentration, the impact of the fulcrum displacement is small. Therefore, it is often used to manufacture complex-shaped shafts.

H7H8h6 is a national standard shaft tolerances with the provisions of (uniform provisions to facilitate the exchange of drawings), The letters that begin with a capital letter (such as H7, K7, and Js7) indicate the hole tolerance, and the letters that begin with a lowercase letter (such as h7, k7, and js7) indicate the axis tolerance.

The specific tolerances represented by these tolerance codes must be determined based on the size of the basic dimensions. If 100h7,100 is the basic size (design theory size), 100h7 through the tolerance tolerance manual, its tolerance is (0,~0.035), unit mm. For 200h7, the tolerance is (0,~0.046) in mm. In the general design process, the tolerances of the corresponding shaft holes are determined based on the matching of the base hole system. They generally differ by one grade. The tolerances are in the specific processing of solid parts, generally take the principle of the largest entity.

The tolerance level of the shaft or housing bore that matches the bearing is related to the accuracy of the bearing. For shafts fitted with P0-group precision bearings, the tolerance group is generally IT6, and the housing bore is generally IT7. For applications with high requirements for rotational accuracy and smoothness of operation (eg, motors, etc.), the shaft should be IT5 and the housing bore should be IT6.

Structural classification

The structural design of the shaft is an important step for the design of the shaft to determine the reasonable shape of the shaft and the overall size of the shaft. It consists of the type, size, and position of the mounting parts on the shaft, the fixing of the parts, the nature, direction, size, and distribution of the load. The type and size of the bearing, shaft blanks, manufacturing and assembly processes, installation and transport, and the shaft deformation and other factors. The designer can design according to the specific requirements of the shaft. If necessary, several options can be done for comparison. In order to select the design scheme, the following is the general shaft structure design principle:

1, save materials, reduce weight, as far as possible the use of equal-strength dimensions or large cross-sectional coefficient of the cross-sectional shape;

2, the shaft part is easy to pinpoint, solid, assembly, disassembly and adjustment;

3, the structure of various measures to reduce stress concentration and increase in strength;

4, to facilitate manufacturing and to ensure accuracy.

5. The nature, size, direction and distribution of the load;

6, shaft machining process and assembly methods.

7. The shaft and the parts mounted on the shaft must have an accurate working position;

Machining – Material Removal Processes

MachJasa Machining Medan ining is a term used to describe avariety of material removal processes in which a Jasa Machining Medan cuttingtool removes unwanted material from aworkpieceto produce the desired shape. The workpiece is typically cut from alarger piece of stock,which is available in a variety ofstandard shapes, such as flat sheets, solid bars, hollow tubes,and shaped beams. Machining can also be performed on anexisting part, such as a casting or forging.

Parts that aremachined from a pre-shaped workpiece are typically cubic orcylindrical in their overall shape, but their individualfeatures may be quite complex. Machining can be used tocreate a variety of features including holes, slots,pockets, flat surfaces, and even complex surface contours.Also, while machined parts are typically metal, almost allmaterials can be machined, including metals, plastics,composites, and wood. For these reasons, machining is oftenconsidered the most common and versatile of allmanufacturing processes.

As a material removal process,machining is inherently not the most economical choice for aprimary manufacturing process. Material, which has been paidfor, is cut away and discarded to achieve the final part.Also, despite the low setup and tooling costs, longmachining times may be required and therefore be costprohibitive for large quantities. As a result, machining ismost often used for limited quantities as in the fabricationof prototypes or custom tooling for other manufacturingprocesses. Machining is also very commonly used as asecondary process, where minimal material is removed and thecycle time is short.Due to the high tolerance andsurface finishesthat machining offers, it is often used to add orrefine precision features to an existing part or smooth asurface to a fine finish.

As mentioned above, machining includesa variety of processes that each removes material from aninitial workpiece or part. The most common material removalprocesses, sometimes referred to as conventional ortraditional machining, are those that mechanically cut awaysmall chips of material using a sharp tool. Non-conventionalmachining processes may use chemical or thermal means ofremoving material. Conventional machining processesare often placed in three categories – single pointcutting, multi-point cutting, and abrasive machining.Each process in these categories is uniquely defined bythe type of cutting tool used and the general motion ofthat tool and the workpiece. However, within a givenprocess a variety of operations can be performed, eachutilizing a specific type of tool and cutting motion. Themachining of a part will typically require a variety ofoperations that are performed in a carefully plannedsequence to create the desired features.Material removal processesMechanicalSingle-point cuttingTurningPlaning and shapingMulti-point cuttingMillingDrillingBroachingSawingAbrasive machiningGrindingHoningLappingUltrasonic machiningAbrasive jet machiningChemicalChemical machiningElectrochemical machining (ECM)ThermalTorch cuttingElectrical discharge machining (EDM)High energy beam machining

Single point cutting refers tousing a cutting tool with a single sharp edge that isused to remove material from the workpiece. The mostcommon single point cutting process is turning, in whichthe workpiece rotates and the cutting tool feeds intothe workpiece, cutting away material. Turning isperformed on a lathe or turning machine and producescylindrical parts that may have external or internalfeatures. Turning operations such as turning,boring, facing,grooving, cut-off (parting),and thread cuttingallow for a wide variety of features to be machined,including slots, tapers, threads, flat surfaces, andcomplex contours. Other single point cutting processesexist that do not require the workpiece to rotate, suchas planing and shaping.

Multi-point cutting refers to using acutting tool with many sharp teeth that moves against theworkpiece to remove material. The two most commonmulti-point cutting processes are milling and drilling. Inboth processes, the cutting tool is cylindrical with sharpteeth around its perimeter and rotates at high speeds. Inmilling, the workpiece is fed into the rotating tool alongdifferent paths and depths to create a variety of Jasa Machining features.Performed on a milling machine, milling operations such asend milling,chamfer milling,and face milling are used tocreate slots, chamfers, pockets, flat surfaces, and complexcontours. Milling machines can also perform drillingand other hole-making operations as well.

In drilling, therotating tool is fed vertically into the stationaryworkpiece to create a hole. A drill press is specificallydesigned for drilling, but milling machines and turningmachines can also perform this process. Drilling operationssuch as counterboring,countersinking,reaming,and tapping canbe used to create recessed holes, high precision holes,and threaded holes. Other multi-point cutting processesexist that do not require the tool to rotate, such asbroaching and sawing.

Abrasive machining refers to using atool formed of tiny abrasive particles to remove materialfrom a workpiece. Abrasive machining is considered amechanical process like milling or turning because eachparticle cuts into the workpiece removing a small chip ofmaterial. While typically used to improve the surface finishof a part, abrasive machining can still be used to shape aworkpiece and form features. The most common abrasivemachining process is grinding, in which the cutting tool isabrasive grains bonded into a wheel that rotates against theworkpiece. Grinding may be performed on a surface grindingmachine which feeds the workpiece into the cutting tool, ora cylindrical grinding machine which rotates the workpieceas the cutting tool feeds into it. Other abrasive machiningprocesses use particles in other ways, such as attached to asoft material or suspended in a liquid. Such processesinclude honing, lapping, ultrasonic machining, and abrasivejet machining.

What is CNC MachiningCNC, or computer numerical control machining, is a subtractive manufacturing method that leverages a combination of computerized controls and machine tools to remove layers from a solid block of material. The desired cuts in the metal are programmed according to corresponding tools and machinery, which perform the machining task in an automated fashion.

How large of a part or panel can be CNC machined?RapidDirect can accommodate the prototyping and production of large machined parts, plastic or metal. Our maximum CNC machining build envelope is 2000 mm x 1500 mm x 300 mm — suitable even for Jasa Machining Medan large-scale parts such as furniture and architectural components.

What kind of a finish does CNC machining leave?Due to the spinning motion produced by the CNC milling machine’s cutter, the surface finish of CNC machined parts will have visible toolmarks. If you require a smooth, unblemished finish to your part, we recommend choosing a secondary finish: grained finish (can only be applied to the outside of machined enclosures due to geometry) or powdercoat.

Mesin Roll Plate (rol Plat, Bending Roll)

Mesin roll plate atau mesin rol plat atau bending roll merupakan salahsatu alat yg sangat diharapkan buat membuat tangki juga pipa. Karena mesin roll ini bisa membarui plate menjadi gulungan-gulungan yang berbentuk bundar . Jadi, wadah-wadah misalnya tangki yg biasa anda lihat di tempat tinggal-tempat tinggalanda itu cara pembuatannya dengan memakai mesin roll atau kadang dianggap dengan bending roll. Bagi yg ingin menekuni usaha, mungkin indera ini sanggup anda gunakan buat menjalankan bisnis anda, lantaran usaha seperti ini masih tergolong langka di Indonesia, tidak misalnya usaha-usaha lainnya yang poly seJasa Roll Plat kali pesaingnya. Harganya pun nir terlalu banyak menguras kantong bila dibandingkan dengan mesin-mesin berat lainnya.

Mesin roll plat ditinjau berdasarkan segi bentuknya, digolongkan dalam tiga macam. Meskipun sebenarnya masih ada jenis-jenis roll plate lainnya, ini hanya garis besarnya saja.Mesin bending roll 3 roll, dikatakan misalnya ini lantaran Jasa Roll Plat medan rollnya ada tiga dan membentuk segi tiga. 2 berada dibawah yg disusun secara sejajar & yg lainnya berada di atas yg mengakibatkan susunannya miripdengan segitiga. Penggeraknya menggunakan dua asal sekaligus, yakni memakai hydrolic & motor listric. Alat ini umumnya dipakai buat  menggulung plate-plate yang tebal bahkan beberapa mesin roll lain yang memakai 3 roll ini kadang digunakan buat menggulung plate menciptakan Jasa Roll Plat medan kerucut atau dikenal dengan istilah cone bending, fungsi bentuk kerucut gak mesti dimiliki mesin bending 3 roll, soalnya kapasitas atau kekuatannya harus dua kali lipat besarnya buat menciptakan sebuah plate kerucut. apabila hanya membangun tangki atau pipa biasa kapasitasnya lebih rendah.

Mesin bending roll empat roll, Tidak seperti jenis sebelumnya, mesin 4 roll ini lebih mudah dalam melakukan penggulungan plat. Soalnya dapat dipasang pada sisi juga sejajar dg meja. dua roll berada pada atas dan bawah yg dua lagi berada di sisi kanan dan kiri. Dengan mesin ini, untuk membuat plat kerucut pula lebih gampang & indah. Ketika proses penggulungan, terdapat proses prebending, yakni ketika pucuk plat yg diroll jadi keras sekali yang membuatnya permanen lurus (gak tergulung secara sempurna), umumnya pucuknya dipotong & dibuang, namun menggunakan mesin bending empat roll inilah hal demikian dapat diminimalisir & semuanya mampu tergulung. Kemampuannya yg lebih akbar dari dalam mesin 3 roll inilah yang mampu melakukan hal seperti ini. Intinya, mesin 4 roll adalah mesin hasil penyempurnaan berdasarkan mesin 3 roll.

Mesin bending roll asimetris, Di antara seluruh jenis mesin roll plate, mesin roll asimetris merupakan mesin yg paling sederhana dibandingkan dengan yg lainnya. Meskipun memakai 3 roll, tetapi susunannya asimetris, yang duaroll dipakai buat menjepit dan yang lainnya digunakan buat mengarahkan. Lantaran tergolong sederhana, untuk mengeroll plat pun sanggup menggunakan tenagamanusia. Tetapi nir jarang tenaganya dari berdasarkan hydrolic ataupun motor listric. Dan tentunya alat ini digunakan hanya untuk menggulung plat yang tipis saja lantaran memang kekuatan rollnya sangat mini.
