A method for manufacturing a one-piece pcd milling cutter head

Abstract

The invention relates to the technical field of precision machining, and discloses a method for manufacturing a one-piece PCD milling cutter head, which includes the following steps: using the first copper wheel to process several Helical chip flutes, the cutting edge is defined between two adjacent chip flutes; the second copper wheel is used to process the broken tooth groove on the front end of the PCD base material in a mechanical grinding and electrolytic way, so that the setting The two chip pockets on the opposite sides of the PCD base material are in communication with each other correspondingly. The beneficial effects of the present invention are: high processing efficiency, the surface quality of the forming surface can be effectively improved by adjusting the processing parameters of electric discharge, and the cost is relatively low, the processing method is reliable, and the stability of the one-piece PCD milling cutter head can be guaranteed .

Description

technical field [0001] The invention relates to the technical field of precision machining, in particular to a method for manufacturing a one-piece PCD milling cutter head. Background technique [0002] Polycrystalline diamond (PCD) milling cutter head has the characteristics of high hardness, high compressive strength, good thermal conductivity and wear resistance, and can obtain high processing accuracy and processing efficiency in high-speed cutting. At present, the main manufacturing method of the PCD milling cutter head is to weld the PCD blade to the outer surface of the cutter body, which will lead to poor stability of the PCD milling cutter head and the blade is easy to fall off. [0003] In response to this technical problem, an integrated PCD milling cutter head has been developed, which integrates the cutting edge on the surface of the cutter body, which can greatly improve the stability of the PCD milling cutter head. However, since the PCD milling cutter head i...

Problems solved by technology

However, because the PCD milling cutter head is usually used for precision machining of micro-milling, the structure is small, and the cutting edge formed on the surface of the cutter body is more complicated, and the precision requirements are high.

For some traditional mechanical processing, such as grinding processing, the tool body is subjected to a large force during the processing process, which is easy to deform, and the forming time is long and the efficiency is low; when using ultrasonic processing, the forming process is complicated and the processing cost is high. It is conducive to mass production; the use of laser processing cutter head is still in the research stage, the processing accuracy is low, and the molding quality cannot meet the requirements
