The most common metal processing technology is milling. In terms of productivity, this method is superior to planing, but inferior to external stretching, and even then only in conditions of large-scale production. For operations, machines are used for which metal cutters are required.
The processing kinematics is characterized by the rotation of the tool along its axis and the feed movement. The last action can also be rotational, helical or linear translational. Milling cutters for metal allow the processing of various cylindrical surfaces, grind the necessary grooves and grooves in the workpieces, and also carry out other operations.
The variety of work performed on the machines provides for the presence of different tools that differ in size, shape and type.
A metal mill is a body of revolution that touches the surface of a part during processing. The tool has cutting teeth on its surface.
Cylindrical varieties were widely used. They are used on horizontal machines. This tool has both straight and helical teeth. The latter option works very smoothly and is widely used in production.
Milling cutters with straight teeth are in demand only for machining narrow planes, when there will be no particular benefit from using a screw type. Products are made of high - quality high - speed steel, equipping them with screw or flat carbide inserts.
End types are widely used in vertical machines. Their axis is set perpendicular to the plane of the workpiece. In end mills, in contrast to cylindrical mills, only the tops of the cutting edges are profiling, and end mills act as auxiliary ones. The main load is borne by the cutting side edges, which are located outside. The end tool provides high performance, which leads to its use in many types of work.
Disk options allow you to cut grooves and manholes in the workpiece. Grooving cutters have teeth that are designed to perform relatively shallow recesses. The tool can also have inclined and straight teeth, providing high performance.
End mills for metal allow you to make deep grooves in the body elements of the contour grooves, mutual perpendicular planes and ledges. The tool is fixed on the machine with a cylindrical or tapered shank. The main work of these products is made by cutting main edges, which are located on a cylindrical surface. The end auxiliary cutting edges are only engaged in cleaning the bottom of the groove. This type of milling cutter is usually made with inclined or helical teeth. The angle of inclination reaches 45 degrees.
In addition to the described varieties, angular, key, shaped and other types of tools are actively used.
