According to the characteristics of the grinding machine's movements and technological requirements, there are the following requirements for electric power dragging and control:
1. The rotational motion of the grinding wheel generally does not require the speed control, which can be dragged by a three-phase asynchronous motor and requires only one-way rotation. When the capacity is large, Y-delta step-down startup can be used.
2. In order to ensure the processing precision, make it run smoothly and ensure that the inertia of the workbench is small when the reciprocating motion is reversed, so the hydraulic drive is used to realize the reciprocating motion of the worktable and the horizontal feed of the grinding wheel box.
