Hard alloy tool bit of precision machine tool

Abstract

The invention relates to the technical field of alloy tool bits, in particular to a hard alloy tool bit of a precision machine tool. A cavity, a first vent hole, a second vent hole, a third vent hole, a chip groove and a protruding block are included. The air enters the first vent hole, then enters the second vent hole through the first vent hole and then enters the third vent hole through the second vent hole, the air is blown out of the chip groove through the third vent hole, the air accelerates discharging of chips, and therefore the phenomenon that the tool bit is burnt due to blockage of the chip groove is avoided, and the use efficiency of the tool bit is improved. When the chips make contact with the protruding block, the arc-shaped face of the protruding block guides the chips and guides the chips to flow out of the chip groove , and when the air blows the chip groove through the third vent hole, the chips are further discharged out of the chip groove in an accelerated mode, so that the phenomenon that the tool bit is burn out due to the fact that the chip groove is blocked is avoided, and the service life of the tool bit is prolonged.

Description

technical field [0001] The invention relates to the technical field of alloy cutter heads, in particular to a hard alloy cutter head for precision machine tools. Background technique [0002] Alloy cutter heads can be divided into three categories by cutting motion and blade shape; general tools, such as turning tools, planers, milling cutters, boring cutters, drills, reamers, reamers and saws, etc.; forming tools, such tool blades and The same or almost the same shape of the intersection part of the workpiece, such as forming turning tools, forming planers, forming milling cutters, broaches, tapered reaming drills and thread processing tools; the existing cutter heads are multi-purpose and CNC machining, milling machine processing, drilling machines machining and lathe machining. [0003] There is also a patent in the prior art about a technical solution for a precision machine tool carbide cutter head. For example, a Chinese patent with the application number CN2019219331...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology and solve the problem that there are too many chips in the chip discharge groove in the prior art, the chip discharge groove cannot carry out chip removal, so that the friction of the cutter head is overheated, and the phenomenon of burning of the cutter head occurs, resulting in The problem of reduced service life occurs; the present invention proposes a precision machine tool carbide cutter head
