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.

Referring to fig. 1 to 3, a diamond cutter for milling long side, including cutter body 1, the one end of cutter body 1 is provided with handle of a knife 2, the transversal of cutter body 1 is personally submitted circularly, cutter body 1 deviates from the circumferencial direction of 2 one ends of handle of a knife and is provided with three groups of cutting teeth uniformly, every group cutting tooth includes the cutter tooth that blade 3 constitutes, the cutter tooth is four rows of three rows of settings, blade 3 salient is in the periphery of cutter body 1, be provided with the blade groove 11 that corresponds the setting with blade 3 in the cutter body 1, diamond blade welds in the blade groove, the blade groove has the chip removal function concurrently, the terminal surface center of handle of a knife 2 is provided with blind hole 4, blind hole 4 extends to in the cutter body 1, be provided with in the blade groove 11 and communicate in the cooling hole 5 of blind hole.

According to the technical scheme, the cooling liquid is injected into the cutter through the blind hole in the end portion of the cutter handle, the cutter is cooled and then sprayed to the diamond blade through the cooling hole, the diamond blade is cooled, meanwhile, scraps accumulated in a scrap discharge groove can be washed out, the scrap discharge performance is greatly improved, the diamond texture blade arranged on the cutter body has the advantages of extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, low affinity with nonferrous metals and the like, the blades are arranged in a row and can be machined to form long side faces, the blades are arranged at intervals, good heat dissipation performance is achieved, the cooling hole is increased, the cooling effect is further improved, the service life of the cutter is prolonged, and the machining precision is improved.

Further, adjacent blades 3 in the same row of teeth are arranged at a circumferential interval of 15 °.

Further, adjacent blades 3 in the same row of cutter teeth are axially arranged at intervals, adjacent rows of cutter teeth are axially overlapped end to end, and the length of the overlapped part is 2 mm.

Further, the adjacent cutter teeth are arranged at intervals of 30 degrees in the circumferential direction.

Among the three above-mentioned technical scheme, the third row and the fourth row blade of each row coincide with the first row and the second row blade of back row again circumferencial direction respectively, and the blade axial coincidence of same row in the adjacent row is 2mm, and the axial head and the tail also coincide 2mm between the adjacent row sword tooth, avoids blade overlap joint to leave the processing vestige, and the multiple blade is processed repeatedly, improves the machining precision, and the interval sets up between the blade, and the cutting heat can not concentrate, is favorable to the heat dissipation.
