The most common processing technologymetal is milling. In terms of productivity, this method is superior to planing, but is inferior to external stretching, and even then only in large-scale production. For the execution of operations, machine tools are used, for which metal cutters are required.
The kinematics of processing is characterized by rotationtool in its axis and feed motion. The latter action can also be rotational, helical or linear translational. Mills for metal allow the processing of various cylindrical surfaces, grind in the workpieces necessary grooves and grooves, as well as carry out other operations.
The variety of work performed on machines provides for the availability of different tools, differing in size, shape and type.
The metal cutter is a body of rotation that touches during the machining of the workpiece surface. The tool has cutting teeth on its surface.
The cylindricalvariety. They are used on horizontal machines. This tool has both straight and screw teeth. The latter option works very smoothly and is widely used in production.
Cutters for metal with straight teeth are in demandonly for the processing of narrow planes, when there will be no special benefit from using a screw type. Products are made of high-quality high-speed steel, equipped with screw or flat carbide plates.
End types are widely used in verticalmachine tools. Their axis is set perpendicular to the plane of the workpiece. In end mills, in contrast to cylindrical ones, only the tops of the cutting edges are profiling, and the end ones act as auxiliary ones. The main load is taken by the cutting side edges, which are located outside. The end tool provides high productivity, which causes its use in many types of work.
Disk options allow you to cut through the workpiecegrooves and manholes. The slotted cutters have teeth that are designed to perform relatively shallow grooves. The tool can also have inclined and straight teeth, ensuring high productivity.
End mills for metal allow performingdeep grooves in the body elements of contour dredges, mutual perpendicular planes and ledges. The tool is fixed to the machine using a cylindrical or tapered shank. The main work of these products is made by cutting the main edges, which are located on a cylindrical surface. Edge auxiliary cutting edges are engaged only in cleaning the bottom of the groove. This type of milling cutters is usually produced with inclined or helical teeth. The angle of inclination is up to 45 degrees.
In addition to the described varieties, angular, keyed, shaped and other types of tools are actively used.
