Chamfering tool for metal
Kopal chamfering tool
Chamfering tools KOPAL for mechanically controlled machines. convenient and productive chamfering.
KOPAL Metal Beveling Tool for use on mechanically controlled machines. Convenient and productive solution to the problem of round beveling.
Methods of chamfering give the trouble and the need to organize special devices and change the existing equipment, in this case Kopal tool can help productively and safely chamfer with or without any stationary or mobile equipment.
If single chamfering operations are required, then the simplest chamfering machines are the right choice.
If, however, the task is of a mass character and serial chamfering is required, then a more universal chamfering machine is needed. Automatic chamfering machines and their accessories are quite expensive. The use of any mills for chamfering also implies machine equipment.
Universal devices for chamfering are multi-purpose Kopal devices produced by Carrosino SAS, France.
They can be used for chamfering as an attachment to a drill (angle grinder) or an electric screwdriver, and also installed in the chucks of drills, milling machines or lathes. In the first case, chamfering nozzles Kopal can effectively replace a variety of equipment chamferers and remove the chamfer with an ordinary electric screwdriver or drill. The chamfering machine is one of the most budget-friendly and effective solutions.
KOPAL chamfering tools for chamfering the following types of workpieces safely and quickly
If the above photo reflects your production requirements, then this is probably the best and most productive solution!
Versatility and convenience of this solution is confirmed by numerous positive reviews from Russian manufacturers of hardware, fasteners, locks and ironmongery, axles.
It is noteworthy that you only need to buy a metal chamfering machine Kopal once, and then, as wear and tear, change only the blades. Knife life is approximately 60,000 parts!
Chamfering machines
In the process of creating threads, trimming pipes and some other types of processing of rounded metal workpieces, burrs may form on their edges, which create certain inconveniences, in particular. interfere with the process of joining products. And, in addition, such irregularities can cause injury with sharp edges. For this reason, they must be removed with certain tools, such as a metal pipe chamfering machine or an edger.
Light edging machines
Let me say right away that the equipment of this category allows you to process an edge only at an angle. If you require additional tasks, such as facing, feel free to skip to the next section ‘Universal Edge Cutting Machines’.
Ultra lightweight automatic edger UZ-12
As the name suggests, the maximum bevel width is 12 mm. this is achieved by shearing off the material with a special bevel cutter, achieving a high working speed of 1.8 m/min and an almost silent operation. With a weight of 30 kg, which is unprecedented for this machine type, the machine can be moved around the workshop by one person without using any special tools. over, the machine uses a worm-type gearbox, thanks to which the manufacturer’s warranty declared for 5 years! High cutter life and re-sharpening capability are also worth mentioning.

The powerful automatic edger UZ-18
New at! One of the most productive automatic bevelers on the market!
Combines all the benefits of the listed models with even greater performance. Maximum chamfering up to 18 mm, processing speed of 1.9 m/min. A worm type gearbox is used which allows you to extend the warranty period to 5 years!
Thus, it can be noted that these models allow you to easily perform double-sided chamfering of X and K shape, without the need to turn cumbersome sheets. The edging process is fast and silent. And the universal 3D manipulator makes it easy to move the equipment around the shop.
What chamfering for pipes is better to use. types and features of tools and devices
Despite the current relevance of plastic, in construction work still use steel pipe, whether it is the installation of plumbing, heating, electrical wiring, etc. In all these cases, welding activities and pre-preparation of metal products for them are required. In this case, the pipe chamfering tool will play a key role.
Edge treatment, chamfering
Edge machining (chamfering). technological operation to prepare material surface for welding. The quality of this procedure directly influences the reliability and durability of the welded structure, e.g. bridge abutments. No one likes to see bridges crumbling.
In order to choose the right edge cutter you must clearly understand what you want to do: cut sheet metal, pipe or complex geometries, or all in one.
Automatic chamfer cutters are suitable for plants in which edging is performed regularly and in large quantities. Their basic material is long straight sheets (UZ-50) and short flat parts (SBM-500). Some automatic chamfering machines can also be used for pipes. See example of processing sheet metal with automatic edger.
Samples of chamfering with automatic chamfer cutters
Manual chamfering machines are used when maximum flexibility is required of the equipment and the width of the chamfer does not exceed 22 mm. With their help it is possible to process curved surfaces, round off an edge for painting, make countersinking of holes, process pipe ends and many other things. As a rule, customers prefer manual machines because of their low cost, compactness, versatility and high reliability (there is nothing to break there).
Separate mention should be made of pipe end processing machines. They have a special design that ensures a rigid mounting on the curved surface. They are selected on the basis of diameter range
In addition to differences in the types of tasks performed, modern chamfering cutters are distinguished by machining methods.
Edge-splitting machines use special solid cutters, while edge-splitting machines use milling heads with carbide inserts. End mills and pipe cutters use cutters with specific angles and tool types. As you see, the range of equipment and consumables is quite wide. You can find all these items on our site in the section of accessories for edgers, and if you do not find something or you have a question, you can always call us and consult us.
Manual chamfering machines (edgers)
Manual chamfering machines (edging machines, manual edgecutters) are the equipment for preparing edges of metal workpieces (sheets, pipes) for welding or painting.
Important advantage is the versatility of their application. it is possible to bevel straight and curved sheets, pipes (shells, offsets), machining holes with diameter of 6.8 mm and more! Manual chamfering machines allow to chamfer up to 21 mm width at angles from 0° (facing) to 60°, as well as to round off the edge at a radius of 1.5-5 mm.

Outer chamfering
Find and deliver cutting tools for external chamfering with highest productivity.
Kopal external chamfering tool provides high performance and external chamfering of parts of rotary bodies type, including multifaceted. Often referred to as an external chamfer deburring tool, and in keeping with its design. it is in essence a reverse taper countersinking tool that can be used on hand operated machine tools or simpler mobile units, up to and including the use with a conventional drill.
The working principle of the back countersink for chamfering is relatively simple. when the tool contacts the workpiece, the guide cone moves in the opposite direction to the feed rate, exposing the blade that cuts the edge of the workpiece.
The Kopal reverse chamfer counterbore consists of a housing with blade holders and a guide cone, which is used to center the device over the workpiece. The body has variations in shank design, cylindrical or Morse taper.
This tool is used for deburring and external chamfering. It is quick to set up and extremely safe to use, thanks to its concept. When working on external chamfering there is absolutely no risk of jamming and breakage of knives, and the workpiece can be held by hand.
Note that unlike other tools, external chamfering machines KOPAL only need to be purchased once and then only need to change blades as they wear out. The blades are made of a special alloy, are sharpened on both sides and allow for the processing of up to 60,000 parts.
Production
Seamless hot-deformed steel pipes are produced from round billets. rods.
This is the billet for a seamless pipe. Not yet stitched.
In general, the fabrication process is as follows
- The workpiece is heated to a temperature at which the steel becomes malleable;
- It is then transformed into a hollow cylinder. a sleeve. in the piercing mill;
- The still-hot workpiece is then fed into countless rollers, where it is drawn and crimped to the desired diameter and wall thickness. All this time inside the hollow cylinder of the sleeve remains a mandrel;
- In the final step the tube is calibrated by the rollers, cooled and cut to length.
Here you can see several production steps.
Important: cold-deformed seamless steel tube is made in much the same way. The only difference is that after the piercing and before rolling, it is water-cooled. In addition, it necessarily requires heat treatment after rolling.
This 88 Tool Will Change Your Metal Work Forever!
Of course, the description is very primitive and general. The details of the technology may differ depending on the type of blank (it can be ingot, forged, continuously cast or rolled), method of rolling of the thermowell (in fact, the thermowell can be produced not only by piercing, but also by extrusion. pressing the metal through an annular slot) and many other parameters.
Manual mechanical edge cutters (rimmers)
Among the hand-held tools are the following two designs:
Pencil type. This manual chamfering machine has a convenient cylindrical handle, into which replaceable carbide inserts are inserted. Replaceable blades are made in the form of curved hooks of different diameters with sharp edges. Thanks to them, it is possible to chamfer inner pipe ends and also in straight lines and recesses.
Pencil chamferers are suitable for soft metals: copper, aluminium, stainless steel. Their approximate cost. 15. 20 u.е.
Cylindrical (barrel). This tool is designed as a short cylindrical head. A convex cone on one side and a similarly tapered recess on the other.
Depending on the manufacturer, cylindrical chamfers have different types of cutting edges. For example, companies like Rothenberger, Rems, Kraftool produce their products completely in metal, placing solid carbide cutters inside. These rimmers have up to 40 cutting edges.
Cheaper bevelers (Zubr, some Rothenberger models) have a metal or plastic (economy class products) body, inside which are placed a small number of cutting plates, usually not more than three.
Pipe sizes that can be processed by Rothenberger cylindrical chamferers 3 36 mm, which in inches is the size of 1/8 to 1 3/8. Some units have slightly different ranges, for example 3/16 to 1 1/2.
There are also larger sized rimmers, for example Rems REG 10-54 is designed for work with pipe diameters from 10 to 54 mm.
Cylindrical bevel cutters are designed to work with pipes made of plastics, copper, aluminum, stainless steel.
Approximate cost of all-metal edge cutters is 50 to 100 y.е., the plastic ones are a whole lot cheaper.
