Description

A kind of superhard cutter with chip-breaker
Technical field
The utility model belongs to superhard cutter technical field, and in particular to a kind of superhard cutter with chip-breaker.
Background technology
In the prior art, for chip chip breaking, common mode is exactly that chip-breaker is set on blade, existing with disconnected Consider the blade of groove to be worth doing, the chip-breaker held can play excellent chip process performance when cutting depth is less than 0.3mm.But It is the increase that cutting depth is usually associated with the roughing stage, chip is not easily broken, and influences workpiece surface processing quality, together When also have an impact to the safety of operator, chip also needs to manually handle, and waste of manpower, influences work efficiency.
Roughing for moulding material, cutting speed increase, chip Essential Edges shape reduce, volume bits diameter increase, chip breaking Effect is deteriorated;When cutting depth increases, chip is difficult.At present, the roughing to moulding material be generally adopted by alloy cutter, Coated cutting tool and the PCBN cutters without chip-breaker, chip is mostly continuous chip, to the serious wear of blade, causes roughing The service life of stage blade is shorter, increases blade exchange number, relatively just reduces production efficiency.
Utility model content
The utility model aim is to provide a kind of superhard cutter with chip-breaker, can solve continuous chip in production process The problem of scratching workpiece or winding cutter, reduce the probability of cutter heel and toe wear damage, extend cutter life.
To achieve the above object, the utility model provides following technical scheme:
The utility model provides a kind of superhard cutter with chip-breaker, including 80 ° of diamond shaped insert matrixes and cutter head, described The first chip-breaker is symmetrically arranged with the cutter head at the major axis both ends of 80 ° of diamond shaped insert matrix upper surfaces, first chip-breaker The distance of bottom surface and 80 ° of diamond shaped insert matrix upper surfaces is 0.25mm, and the angle of first chip-breaker is more than 80 ° of diamond shaped inserts The apex angle of matrix longitudinal end cutter edge, the intermediate vertex A of the first chip-breaker and the distance of cutter edge are 0.8mm, and first is disconnected It is 20 ° that groove is considered to be worth doing with the angle that cutter edge is formed;
It is symmetrically arranged with the second chip-breaker on the cutter head at the short axle both ends of 80 ° of diamond shaped insert matrix upper surfaces, described second The distance of the bottom surface of chip-breaker and 80 ° of diamond shaped insert matrix upper surfaces is 0.25mm, and the angle of second chip-breaker is more than 80 ° The apex angle of diamond shaped insert matrix short axle end cutter edge, the intermediate vertex B of the second chip-breaker and the distance of cutter edge are 0.51mm, the second chip-breaker are 20 ° with the angle that cutter edge is formed;The angle α of first chip-breaker 2 is less than the second chip-breaker 3 Angle β.
Further, the length of first chip-breaker is more than the length of the second chip-breaker.
Further, the angle α of first chip-breaker is 100 °.
Further, the angle β of second chip-breaker is 120 °.
Relative to the prior art, the beneficial effects of the utility model are:
The utility model sets chip-breaker on 80 ° of diamond shaped insert matrixes, and can solve continuous chip in production process makes The problem of workpiece scratches or winds cutter, reduces the probability of cutter heel and toe wear damage, extends cutter life, meet high speed The requirement of high-efficient cutting, improves processing environment, protects workpiece surface quality, improves workpiece surface finish.

Embodiment
The utility model is further described with reference to specific embodiment:
As shown in Fig. 1 ~ 4, a kind of superhard cutter with chip-breaker, including 80 ° of diamond shaped insert matrixes 1 and cutter head, described 80 ° The first chip-breaker 2 is symmetrically arranged with the cutter head at the major axis both ends of 1 upper surface of diamond shaped insert matrix, first chip-breaker 2 The distance of bottom surface and 80 ° of 1 upper surfaces of diamond shaped insert matrix is 0.25mm, and the angle of first chip-breaker 2 is more than 80 ° of diamond shape knives The apex angle of 1 longitudinal end cutter edge of sheet matrix, the intermediate vertex A4 of the first chip-breaker 2 and the distance of cutter edge are 0.8mm, the One chip-breaker 2 is 20 ° with the angle that cutter edge is formed;
It is symmetrically arranged with the second chip-breaker 3 on the cutter head at the short axle both ends of 80 ° of 1 upper surfaces of diamond shaped insert matrix, described The bottom surface of two chip-breakers 3 and the distance of 80 ° of 1 upper surfaces of diamond shaped insert matrix are 0.25mm, and the angle of second chip-breaker 3 is big In the apex angle of 80 ° of 1 short axle end cutter edges of diamond shaped insert matrix, the intermediate vertex B5 of the second chip-breaker 3 and cutter edge away from From for 0.51mm, the angle that the second chip-breaker 3 is formed with cutter edge is 20 °;It is disconnected that the angle α of first chip-breaker 2 is less than second Consider the angle β of groove 3 to be worth doing.
