Why is the smoothness of the reversing process for CNC end face cylindrical grinders important

2025-04-11

Why is the smoothness of the reversing process of a CNC end face cylindrical grinder important? CNC end face cylindrical grinder is a commonly used machine tool for mechanical processing. There are high requirements for motion stability, commutation accuracy, and commutation frequency. At present, CNC end face cylindrical grinders are developing towards large-scale production, and some workbenches have reached a reciprocating speed of 40m/min. The motion inertia of large grinding machines is large, and when they change direction, it will cause a sharp increase in back pressure, resulting in a reversal impact, which will have a catastrophic impact on the machine tool. Therefore, the problem of smooth reversal has become an important factor restricting the increase of grinding machine working speed and machining accuracy. The reversing method and control parameters in the system have a decisive effect ...
