Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the present invention provides a cutter head, which includes a cutter head main body 1 and a supporting structure 2, wherein the cutter head main body 1 includes a main cutter body 11 and an auxiliary cutter body 12 corresponding to the supporting structure 2, the main cutter body 11 is disposed on two sides of the auxiliary cutter body 12 to form a structural groove 13 for accommodating the supporting structure 2;

the main cutter body 11 comprises a cutting blade 11a and a vulnerable structure piece 11b for forming a chip removal channel, the vulnerable structure piece 11b is arranged between every two adjacent cutting blades 11a, and the hardness of the vulnerable structure piece 11b is lower than that of the cutting blade 11a.

Specifically, the main cutter body 11 and the auxiliary cutter body 12 each comprise a cutting blade 11a and a fragile structure piece 11b for forming a chip removal channel; and the vulnerable structure piece 11b is arranged between two adjacent cutting blades 11a. When the main cutter body 11 is worn to the auxiliary cutter body 12, the thicknesses of the main cutter body 11 and the auxiliary cutter body 12 are low, and the cutter is not easy to break even without the support of the support structure.

The hardness of the support structure body 2 is lower than that of the cutter head body 1, and then the support structure body can be quickly worn away in the cutting process, so that a large chip removal channel is formed, and large particles of chips can be discharged preliminarily. Meanwhile, the supporting structure body 2 can solve the influence on the overall strength of the cutter head main body 1 due to the arrangement of the structural groove 13, so that the condition of cutter breakage is reduced; preferably, the support structure 2 is made of graphite or other material that is easily worn and not easily deformed.

The fragile structure piece 11b is a metal blade, the cutting blade 11a is a diamond blade, and the fragile structure piece 11b is a metal blade, and has certain wear resistance and cutting performance compared with the support structure body 2, so that the blade edge of the diamond blade is not excessively exposed to cause the blade breaking. It should be noted that the main cutter body 11 has a multi-layer sheet structure, and has weak lateral impact strength, and if the diamond tape sheet is excessively exposed and loses the support of the fragile structure sheet 11b, the main cutter body is easily broken to reduce the service life.

In order to reduce the scratch marks on the processed surface of the cut object, the main cutter body 11 further includes a fine cutting blade 11c for optimizing the cut marks, and the fine cutting blade 11c is disposed between two adjacent cutting blades 11a. Accordingly, the vulnerable structure piece 11b is arranged between the fine cutting blade 11c and the cutting blade 11a

Preferably, the cutting blade 11a and the finish cutting blade 11c are a first diamond blade and a second diamond blade, respectively, and the diamond particle diameter of the first diamond blade is larger than that of the second diamond blade. The first diamond blade and the second diamond large sheet are obtained by sintering metal powder containing diamond, which is the prior art and is not described in detail herein. The larger the diamond particle size of the diamond blade is, the stronger the cutting performance is, but the more remarkable the cutting scratch of the machined surface is. Therefore, by integrally providing the cutting blade 11a and the finish cutting blade 11c, a machined surface with a small scratch can be formed while ensuring the cutting performance of the main cutter body 11.

In order to facilitate the sharpening of the tool bit body 1, the top surface of the tool bit body 1 is provided with a plurality of cutting edge surfaces 14 with preset angles, so that the tool bit body can cut into an object to be cut during initial cutting, and the tool bit body and the object to be cut are prevented from being violently collided. Preferably, the angle of the blade edge face is 120-160 degrees.

Preferably, the tool bit body 1 is a unitary structure.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
