Description

Milling cutter

Technical Field

The utility model relates to the technical field of milling, in particular to a milling cutter.

Background

Milling refers to cutting a workpiece using a rotating throw-away tool, and is a highly efficient machining method. In operation, the tool rotates (performs main movement), the workpiece moves (performs feeding movement), and the workpiece can be fixed, but the tool which rotates must also move (simultaneously performs main movement and feeding movement). Milling machines include horizontal milling machines and vertical milling machines, and also large planer milling machines. These machine tools may be ordinary machine tools or numerical control machine tools. A rotary milling cutter is used as the cutting machining of the cutter. Milling is typically performed on a milling machine or boring machine, and is suitable for machining flats, grooves, various forming surfaces (such as splines, gears and threads), special forming surfaces of dies, and the like.

The diamond cutter is needed to be used in the process of processing the ceramic material, the cutter is required to be frequently replaced according to different processing modes and process requirements, the cutter is suitable for punching, milling grooves and milling faces when the cutter is used for grinding holes, if the processing technology of the ceramic material is complex, the two cutters are required to be alternately replaced, so that a great deal of time is wasted in disassembling and assembling the cutter, and the processing efficiency of the ceramic material is reduced.
