Machining process for bladed full-PCD milling cutter

Abstract

The invention discloses a machining process for a bladed full-PCD milling cutter. Firstly, a notch is formed in the position, close to a PCD part, of a PCD base material by using a tool grinding machine, and then the A-axis difference angle between the notch and the PCD part is measured on a tool detector so as to determine the reference position of machining; and electrolytic grooving, electrolytic chip pocket forming, electrolytic arc rear corner forming and electrolytic end face rear corner forming are sequentially carried out, and finally the bladed full-PCD milling cutter is formed. A copper wheel electrode electrolysis method is adopted for producing the bladed full-PCD milling cutter so that the complex contour on the PCD material can be machined.

Description

technical field [0001] The invention relates to the technical field of tool processing, in particular to a process for processing a full PCD milling cutter with a margin. Background technique [0002] Processing titanium alloys has always been a difficult problem. Using high-speed steel has too low a service life, and using cemented carbide is too slow. It is generally recognized that the best processing material is PCD, but processing PCD materials is very difficult. At present, there are only three methods. Diamond grinding wheel machining, but it is difficult to control the size of the tool, the grinding wheel wears very fast, and the accuracy is difficult to guarantee. The second method is to use electrical discharge machining, but there are two ways of electrical discharge machining, one is wire cutting slow wire, which can only It is impossible to perform simple geometric shape processing, such as chip flute and back engraving, etc.; the second method is laser, but the...

[0002] Processing titanium alloys has always been a difficult problem. Using high-speed steel has too low a service life, and using cemented carbide is too slow. It is generally recognized that the best processing material is PCD, but processing PCD materials is very difficult. At present, there are only three methods. Diamond grinding wheel machining, but it is difficult to control the size of the tool, the grinding wheel wears very fast, and the accuracy is difficult to guarantee. The second method is to use electrical discharge machining, but there are two ways of electrical discharge machining, one is wire cutting slow wire, which can only It is impossible to perform simple geometric shape processing, such as chip flute and back engraving, etc.; the second method is laser, but the cost of laser equipment is expensive, and it is only in the research and development stage, and has not yet fully entered the market. Therefore, it is particularly important to solve such problems
