[0041] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0042] The embodiment provides a tool grinding production line, and specifically, the tool grinding production line comprises a machining operation area and a manual operation area, and the manual operation area is arranged outside the machining operation area.

[0044] In the scheme, a complete control and management system is provided, which is composed of a mechanical hand control system, a main control system, self-developed software and a numerical control system, and specific control is as follows.

[0045] a: the operator completes loading and unloading of the tool disc at the stock bin;

[0046] b: the operator configures the tool type and quantity in the tool disc after replacement on the machine tool panel corresponding to the stock bin;

[0047] c: the machine tool system sends the tool quantity and type information input by the manual tool to the self-developed software;
