Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, the utility model provides a counter bore cutter for bearing processing, including cutter main body 1, cutter main body 1 is last to be provided with two cutter grooves 2 (as shown in fig. 5) that use cutter main body 1's the central axis to be central symmetric distribution as the center, all installs a blade 7 in every cutter groove 2, and during the counter bore cutter was processed, the counter bore cutter was around self axis rotation drive cutter 7 smear metal bearing terminal surface processing counter bore, and blade 7 passes through the fix with screw on the cell wall of cutter groove 2, as shown in fig. 3, preferably, the screw adopts hexagon socket head cap screw 8.
