The most common metal processing technology is milling. In terms of productivity, this method is superior to planing, but inferior to external broaching, and even then only in large-scale production. To perform operations, machines are used that require cutters for metal.
The kinematics of processing is characterized by the rotation of the tool along its axis and the movement of the feed. The last action can also be rotational, helical or linear translational. Milling cutters for metal allow you to process various cylindrical surfaces, grind the necessary grooves and grooves in workpieces, as well as perform other operations.
The variety of work performed on the machines involves the presence of different tools that differ in size, shape and type.
Cutter for metal is a body of revolution that touches the surface of the part during processing. The tool has cutting edges on its surface.teeth.
Cylindrical varieties are 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.
Cutters for metal with straight teeth are in demand only for processing narrow planes, when there will be no particular advantage from using a helical type. Products are made of high quality high speed steel, equipped with screw or flat carbide inserts.
End views are widely used in vertical machines. Their axis is set perpendicular to the plane of the workpiece. In end mills, unlike cylindrical, only the tops of the cutting edges are profiling, and the end mills act as auxiliary ones. The main load is taken by the cutting side edges, which are located outside. The face tool provides high productivity, which leads to its use in many types of work.
Disk options allow you to cut grooves and manholes in the workpiece. Groove cutters have teeth that are designed to make relatively shallow cuts. The tool can also be equipped with beveled and straight teeth for high performance.
End mills for metal allow you to make deep grooves in the body elements of contour recesses, mutual perpendicular planes and ledges. The tool is attached tomachine with a cylindrical or tapered shank. The main work of these products is performed by cutting main edges, which are located on a cylindrical surface. The end auxiliary cutting edges are engaged only in cleaning the bottom of the groove. This type of cutter is usually produced with inclined or helical teeth. Tilt angle up to 45 degrees.
In addition to the described varieties, angular, keyway, shaped and other types of tools are actively used.
