The cutter head is provided with a plurality of spaced mounting platforms along its circumference, the mounting platforms being disposed facing the outside of the reamer; the reamer also comprises a plurality of blades, each mounted on a mounting platform, and the blades being made of polycrystalline diamond. The technical solution of this utility model aims to address the problems of easy wear and poor processing stability of conventional reamers.

[0004] However, when the above-mentioned reamer is in use, the blades are arranged equally on the circumference, and the tooth groove shape and depth are exactly the same on the same outer circle. The cutting amount and cutting speed of each tooth are the same from beginning to end. In this way, since the contact between the workpiece and each cutting tooth is the same during processing, periodic vibration will be generated during cutting, and the cutting resistance will increase, resulting in a rough and poor surface finish of the reamed hole, the presence of polygonal or axial stripes and spiral lines, and a shorter reamer life. Utility Model Content

[0005] (1) Technical problems solved

[0015] Beneficial effects

[0016] The utility model provides a high-strength reamer for machining centers, which has at least the following beneficial effects compared with the prior art:

[0017] With the help of the cooperation of multiple unequal teeth, the smoothness of the reamer's hole repair is improved and the service life of the reamer is extended. The waste chips are discharged through the cooperation of the chip groove, the first chip groove and the second chip groove.
