PCD (Poly Crystal Diamond) thread drilling and milling cutter

Abstract

The invention discloses a PCD (Poly Crystal Diamond) thread drilling and milling cutter, wherein the cutter body is a milling cutter with a thread structure; the cutter body is made of hard alloy; a drill is arranged at the front end of the cutter body; the vertex angle of a drill tip is 130-140 degrees; a first rear angle is 120 degrees; the width is 0.5mm; the second rear angle is 25 degrees; an edge passes through the center; two chip spaces are arranged along the axis of the cutter body; the first rear angle in the radial direction of the middle thread milling cutter part is 15 degrees; the width is 0.5mm; the second rear angle is 20 degrees; a chamfering edge is formed at the rear end of the cutter body, and the edge part of the cutter body is made of a PCD material. The PCD thread drilling and milling cutter has the characteristics that tool positions are reduced; twice processing of two support cutters is merged into a whole; non-manufacturing time generated when the cutter is replaced is reduced, and the service life of the tool is prolonged.

Description

technical field [0001] The invention relates to a machining tool, in particular to a PCD thread drilling and milling cutter. Background technique [0002] In the threaded hole processing of non-ferrous metals and non-metallic materials, the machining center usually uses a cemented carbide drill (PCD drill) to process the threaded bottom hole first, then converts the tool, and uses a tap or a thread milling cutter to tap the thread, requiring two tool positions For processing, it not only occupies a limited tool position, but also increases auxiliary time such as tool change, which cannot give full play to the advantages of CNC equipment in batch processing. Contents of the invention [0003] The invention overcomes the shortcomings in the prior art and provides a PCD thread drilling and milling cutter. [0004] In order to solve the above-mentioned technical problems, the present invention is achieved through the following technical solutions: [0005] A PCD thread drill...
