Embodiment Construction

[0012] Such as figure 1 As shown, the micro-diameter double-edged taper ball knife includes a knife body 1. The knife body 1 is provided with two sets of cutting edges 11, and straight grooves 12 respectively arranged in the middle of the two sets of cutting edges 11, and the two sets of cutting edges 11 and the knife The angle of taper formed between the horizontal planes of the body 1 is 3-7°, the front end of the cutter body 1 is provided with a ball head 13, and the diameter of the ball head 13 is 0.3-0.5mm. The two sets of blades 11 and The angle of taper formed between the horizontal planes of the cutter body 1 is 5°, the diameter of the ball head 13 is 0.4mm, the use effect is good, and the processing is convenient. The positive rake angle of the cutter body 1 is 20°. The cross section of the relief angle of the body 1 is a circular arc, which improves the cutting strength of the cutter body 1, reduces the cutting resistance of the cutter body 1 during the cutting proces...

Abstract

The invention relates to micro-diameter both-edge tapered ball cutter which comprises a cutter body, wherein two cutter edges are arranged on the cutter body; a straight groove is formed in the middle of the two cutter edges; a tapered included angle formed among the two cutter edges and a horizontal plane of the cutter body is 3-7 DEG; a ball head is arranged at the front end of the cutter body; and the ball head is 0.3-0.5mm in diameter. The ball cutter has the advantages that the two cutter edges and the cutter body are arranged in a tapered manner; a lateral folding force of the micro-diameter cutter in the cutting process is dispersed; the processing effect of the cutter body is improved with the adoption of the ball head arranged on the cutter body; the cutter body is not easy to break; the chip removal effect is improved; the processing effect is good; and the cutting efficiency is high.

Description

Technical field [0001] The invention relates to a micro-diameter double-edged taper ball knife. Background technique [0002] Existing micro-diameter ball cutters include a cutter body and a handle, but the existing cutter body has a flat edge, which cannot process the pattern grooves. During processing, the grooves are rough due to the cutting of the side edge. Other shortcomings, during processing, the tool body is easy to break at the boundary of the variable diameter, the chip removal effect is poor, the cutting efficiency is low, the use effect is poor, and the practicability is not high. Summary of the invention [0003] The technical problem to be solved by the present invention is that the existing micro-diameter ball cutter is easy to break, the chip removal effect is poor, the processing effect is poor, and the cutting efficiency is low, thereby providing a micro-diameter double-edged taper ball cutter. [0004] In order to solve the above technical problems, the present ...
