Problems solved by technology

Increasing the processing speed can shorten the processing time and improve the processing efficiency. However, when the XY platform realizes high-speed processing, if the tracking trajectory has a drastic change or there is a large curvature on the contour trajectory, the contour tracking error will increase, which will seriously affect the contour processing accuracy.
