The size of the included angle between the first stop surface 111 and the second stop surface 112 is not limited herein, and is related to the structural shape of the tool a to be processed, and in general, for the tool a to be processed in the form of a quadrangular prism, the first stop surface 111 and the second stop surface 112 may be perpendicular.
In the prior art, the mount pad 1 generally adopts a split structure, and comprises a base body and a support body, wherein the support body is provided with a clamping station, and then the support body is assembled with the base body. Different from the prior art in the form, the embodiment of the invention adopts an integrated structure design, so that the structural rigidity of the mounting seat 1 is greatly improved, and when the tool A to be processed is processed by increasing the grinding amount, the mounting seat 1 has a stable structure and is not easy to deform, thereby being beneficial to improving the processing precision and the processing efficiency of the tool A to be processed.
