Based on the motion characteristics and process requirements of the grinding machine, the following requirements are made for electrical drive and control: 1. The rotational motion of the grinding wheel generally does not require speed adjustment; it can be driven by a three-phase asynchronous motor, and it only requires single-direction rotation. For larger capacities, a Y-delta reduction start can be used. 2. To ensure processing accuracy and smooth operation, as well as to minimize inertia and shock during the reciprocating motion of the worktable, hydraulic transmission is adopted to achieve the reciprocating motion of the worktable and the lateral feed of the grinding wheel box.
