It is generally developed on the basis of CNC cylindrical grinders. Two main technical measures are usually employed for this purpose;
(1) The workpiece spindle is changed to an electric spindle with C-axis control and locking functions;
(2) The grinding wheel headstock adopts double sliding table and or turret type grinding wheel headstock with B-axis swing function to install more than 2 grinding wheels (such as suitable for external and internal grinding, suitable for end grinding For grinding and form grinding, etc.) to meet the needs of different grinding processes.
Since the CNC cylindrical grinder generally has the Z-axis that controls the left and right movement of the worktable and the X-axis that the grinding wheel headstock moves back and forth, so that after the rotary body is clamped on the machine tool, it can not only grind the outer circle, inner circle, Shoulder end face, etc., the C-axis control function of the workpiece axis can also be used to grind flat and polygonal surfaces on the outer surface of the workpiece; various circular surfaces and non-circular surfaces can be ground through the linkage control of X-axis and C-axis. ; Grinding threads through the linkage control of C-axis and Z-axis; using the B-axis of the grinding wheel head frame to swing and grind various conical surfaces with different tapers, etc.
