They are core equipment in tool workshops of tool manufacturing plants and machinery manufacturing plants. The main types include universal tool grinding machines, drill bit grinding machines, broaching tool grinding machines, etc. They are used in the fields of tool regrinding, precision machining, and tool production. During the processing of tool grinding machines, it is necessary to control the movement of the spindle to improve the processing efficiency and applicability of the grinding machine. The spindle head of the tool grinding machine not only needs to play a driving role, but also needs to drive the grinding wheel to lift and lower to achieve the adjustment function. When it is necessary to process some irregularly shaped workpieces, the angle of the grinding wheel needs to be adjusted. If this function is not available, it will affect the processing efficiency of the grinding machine and delay the production efficiency of the workpieces.
