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.
