the tool bit and the tool body are integrally formed, and the tool bit back angle degree is set to be an acute angle.

Preferably, the bottom end of the cutter main body is of a conical structure, and chamfering processing is performed at the bevel edge of the cutter main body.

Preferably, the cutter body is provided with a through hole, and chamfering treatment is performed on two sides of the through hole.

Preferably, a chip groove is formed between one side of the tool bit and the tool body, and the chip groove is of an arc-shaped structure.

Preferably, the top end of the chip groove is inclined forwards by 20 degrees.

Preferably, the front end and the tool bit rear angle are integrally formed with the tool bit.

Preferably, the bottom end angle of the cutter main body is 60 degrees, and circular arc chamfering processing is performed.

Preferably, the head relief angle is between 1 and 3 degrees.

The utility model has the technical effects and advantages that: this rotatory type of finding high efficiency production cutter, tool bit relief angle number of degrees is become 1-3 degrees by traditional 3-5 degrees, and the processing cutter has stabilizing effect before the size is relative, can not produce the size deviation, and the cutter main part can regrind reuse, and horizontal width size is relatively stable, and reduce cost improves production efficiency, reduces the wasting of resources, and the chip removal is smooth and easy can be guaranteed to the anteversion chip groove of 20 degrees, and the product surface is smooth, and the stability of cutter has been guaranteed in setting up of cutter main part bottom 60 degrees angles. This rotatory type of finding high efficiency production cutter, it is rational in infrastructure, stable durable, the practicality is strong, easily promotes.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model is shown in figures 1-4, comprising a cutter body 1 arranged on a cutter seat, wherein the top end of the cutter body 1 is provided with a cutter head 7, and the top end of the cutter head 7 is provided with a front end part 8 and a cutter head back angle 9; the cutter head 7 and the cutter body 1 are integrally formed, and the cutter head back angle 9 degrees is set to be an acute angle and ranges from 1 degree to 3 degrees. The 9 degrees of the rear angle of the cutter head is changed from the traditional 3-5 degrees to 1-3 degrees, the size of the cutter head is stable relative to that of the prior processing cutter, the cutter body 1 can be reground and reused, the transverse width size is relatively stable, the cost is reduced, the production efficiency is improved, and the resource waste is reduced;

the bottom end of the cutter main body 1 is of a conical structure, chamfering processing is carried out on the edges of the bevel edges of the cutter main body 1, a through hole 5 is formed in the cutter main body 1, and chamfering processing is carried out on two sides of the through hole 5, so that the installation is facilitated, and meanwhile, the abrasion is reduced;

a chip groove 6 is formed between one side of the tool bit 7 and the tool body 1, the chip groove 6 is of an arc-shaped structure, the top end of the chip groove 6 inclines forwards by 20 degrees, and the chip groove 6 with the angle of 20 degrees can ensure smooth chip removal, so that the surface of a product is smooth;

the front end 8 and the head relief angle 9 are formed integrally with the head 7. The bottom end angle of the cutter main body 1 is 60 degrees, and the circular arc chamfering treatment is carried out, so that the stability of the cutter is ensured

The working principle is as follows: when the cutter for efficiently producing the rotary small parts is used, the 9 degrees of the rear angle of the cutter head is changed from the traditional 3-5 degrees to 1-3 degrees, the size of the cutter is stable relative to that of a previously machined cutter, the cutter body 1 can be ground and recycled, the transverse width size is relatively stable, the cost is reduced, the production efficiency is improved, the resource waste is reduced, the smooth chip removal can be ensured by the 20-degree front-inclined chip removal groove 6, the surface of a product is smooth, and the stability of the cutter is ensured by the arrangement of 60-degree angle at the bottom end of the cutter body 1;

this rotatory type of finding high efficiency production cutter, it is rational in infrastructure, stable durable, the practicality is strong, easily promotes.
