1.Point control CNC machine tools The characteristic of point control CNC machine tools is that the moving parts of the machine tool can only achieve precise positioning from one position to another, and no processing is performed during the movement and positioning process.The machine tool CNC system only controls the coordinate value of the stroke end point and does not control the motion trajectory between points. Therefore, there is no connection between the movements of several coordinate axes.Several coordinates can move toward the target point at the same time, or each coordinate can move individually and sequentially.This type of CNC machine tools mainly include CNC coordinate boring machines, CNC drilling machines, CNC punch machines, CNC spot welding machines, etc.The CNC device for point control CNC machine tools is called a point CNC device.2.Linear control CNC machine tools Linear control CNC machine tools can control the tool or worktable to perform linear movement and cutting processing in th
