In order to ensure the stability and processing quality during grinding, grinding machine is equipped with support mechanism for fixing and supporting the workpiece to be processed.

[0003] Traditional grinding machine support mechanism usually includes fixed base, clamping device and auxiliary support element, which work together to ensure that the workpiece maintains the correct position and posture during grinding. However, with the increasing demand of industrial manufacturing and technological progress, the traditional support method gradually shows its limitations, especially when facing complex shape or special requirements of workpiece. For example, in the automotive manufacturing, aerospace and mold manufacturing industries, it is often necessary to deal with workpieces with complex curved surface or inclined surface, which requires extremely high machining precision and often needs to be polished at different angles.
