Problems solved by technology

[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

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0017] A PCD thread drilling and milling cutter of M8x1.25 is taken as an example, such as Figure 1-3 As shown, the cutter body 2 is a threaded milling cutter, the cutter body 2 is made of cemented carbide, the front end of the cutter body 2 is a drill, the drill diameter is 6.8 mm, the drill tip angle is 130 ~ 140o, the first relief angle is 12o, and the width is 0.5 mm. Two relief angles are 25o, one of which is over the center. There are two chip flutes along the 2 axis of the cutter body, the diameter of the middle thread milling cutter is 6.5 mm, the thread profile is 60o, the pitch is 1.25, the radial first relief angle is 15o, the width is 0.5 mm, and the second relief angle is 20o , The rear end of the cutter body 2 has a chamfered edge 45o, the diameter is 9 mm, and the handle is hard alloy, the diameter is mm. The cutter body blade 1 is m...

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 processing of threaded holes of non-ferrous and non-metallic materials, the machining center usually uses a carbide drill (PCD drill) to first process the threaded bottom hole, and then change the tool. Tap or thread milling cutter to tap the thread, which requires two tool positions Processing not only occupies a limited number of tool positions, but also increases auxiliary time such as tool change, which cannot give full play to the advantages of CNC equipment in batch processing. Summary 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 implemented through the following technical solutions: [0005] A PCD thread drilling and milling cutter, t...
