What is the difference in clamping method between Dongguan turning and milling composite processing and ordinary lathe processing

The clamping method of Dongguan turning and milling composite processing is similar to that of ordinary lathes. The workpiece is generally clamped by a chuck, center frame, and center. When turning the outer rotating surface, clamp it with a chuck and the center, and clamp the inner rotating surface with a chuck and the center frame; In the milling process, in order to improve clamping stability, a chuck, center frame, and center can be used simultaneously. If the machine tool is equipped with a tailstock, the center frame and tailstock center should be effectively combined to increase clamping strength and reduce chatter during the machining process. In the processing of slender rods, the use of the center frame and tailstock will determine the success or failure of the part processing.

When the chuck center frame center system clamps the workpiece, the workpiece only has the clamping force of the chuck and the top clamping force, and only uses the friction force of the gripper to tighten the workpiece. Under the action of cutting force and top force, the workpiece and chuck can rotate relative and move axially. When turning the rotating surface, if the workpiece rotates relative to the chuck during the machining process, it has little impact on the results of Dongguan turning and milling composite machining. It is only necessary to pay attention to limiting axial movement.
