Before the advent of numerical control digital displays, this was a high-precision curve grinding machine, mostly imported. It reflects the shape of the curve through the refraction of light. It was generally used when processing curved surfaces with high precision requirements, grooves for high-precision parts, internal and external R, complex-shaped and high-dimensional tools, etc. In the past, it was an indispensable device

The utility model is a multifunctional precision grinding machine tool that applies image recognition technology and integrates online detection of the machine tool, online compensation, online dressing of the grinding wheel and open multi-axis digital control. Integrating multi-axis digital control with image recognition processing, up to eight axes can be controlled, including seven servo rotary motors and one servo linear motor. Up to six-axis linkage can be achieved, and different combinations of control axes can be made. The utility model has the characteristics of elegant and generous appearance and strong human-machine compatibility, and is suitable for the processing of various precision and complex contour parts.
