Description
Technical field
The utility model is related to a kind of coolings of high pressure to cut micro- texture lathe tool blade.
Background technology
There are the difficult-to-machine materials such as high temperature alloy, titanium alloy the performances such as higher anti-oxidant, high temperature resistant, corrosion-resistant to have simultaneously
There are the unique comprehensive performance such as good fatigue behaviour, fracture toughness and plasticity, these alloys to be widely used in aero-engine
In parts.But these performances lead to that cutting force is big in process and concentrates, cutting temperature is high, chip breaking is difficult, cutter
The problems such as abrasion badly broken, quality of work piece surface is poor, and tool changing is frequent.High pressure Machining Technology for Cutting is a kind of efficient, high
The cutting technology of essence, it can effectively improve workpiece processing quality during processing above-mentioned material, reduces tool wear, reduces
Production cost.The utility model proposed in this context plays active promoting function to high pressure cooling cutting.
Invention content
The purpose of this utility model is to provide a kind of micro- texture lathe tool blade of high pressure cooling cutting, is existed with solving existing blade
The problem of cutting temperature is high in process, cutting force is big, chip breaking is difficult, parts processing surface is of poor quality etc..
The utility model is in order to solve the above technical problems, adopted the technical scheme that：A kind of high pressure cooling cutting is micro- to knit
Structure lathe tool blade, it includes blade cutter hub, it is characterized as：Cutter hub is diamond shape, and diamond shape acute angle is 80 °, the center of cutter hub
There are circular hole, four sides of cutter hub to be equipped with main cutting edge, tool arc is equipped on two cutting edge junction points that angle is 80 °
There is blunt circle in sword, cutter hub rake face is equipped with chip-breaker, and chip-breaker is by straight line and zigzag circular arc structure at cutting edge
Groove is equipped at point of a knife at, chip-breaker, be equipped at point of a knife it is hemispherical it is micro- knit structure, cutter hub rake face is equipped with boss,
It is equipped with chamfered edge at main cutting edge, Circular Nose Cutting Edge.
The utility model has the advantages that：It is equipped with groove at point of a knife in chip-breaker, is ensureing point of a knife intensity
In the case of so that point area is retained more coolant liquids.Be equipped at the point of a knife it is hemispherical it is micro- knit structure, it is this hemispherical micro-
Knitting structure can make point of a knife cutting region area become larger in a limited space, increase heat dissipation, reduce cutting temperature, while interhemicerebral
Gap can utilize the tension between liquid to retain more coolant liquids, reduce the friction between knife bits.Chip-breaker is by straight line and sawtooth
The groove profile that shape circular arc is constituted reduces abrasion of the chip to cutter, improves machining efficiency and extends cutter life.
