Dongguan CNC processing plant to share with you = turning in the center of the lathe
The basic operations performed by the Dongguan CNC processing plant on a motor lathe have been introduced. Those operations that use a single-point tool on the outer surface are called turning. In addition to drilling, reaming, and grinding internal surfaces, the operations are also done by single-point tools.
All the machining processes in the Dongguan CNC processing plant include turning and boring can be classified as rough machining, finishing or semi-finishing. Finishing is to remove a large amount of material as quickly and effectively as possible, and a small part of the material left on the workpiece is used for finishing. Finishing obtains the final size, shape and surface accuracy of the workpiece. Sometimes, semi-finishing leaves a predetermined amount of material for finishing, which precedes finishing.
Generally speaking, longer workpieces are supported by one or two lathe centers at the same time. The tapered hole, the so-called center hole, is suitable for the center of the lathe to be drilled at both ends of the workpiece-usually along the axis of the cylindrical workpiece. The end of the workpiece close to the frame is usually supported by the center of the tailstock, and the end close to the main bearing is supported by the center of the main bearing or clamped by the claw plate. This method can firmly tighten the workpiece and smoothly transfer the force to the workpiece; the auxiliary support provided by the chuck to the workpiece reduces the tendency of chattering during cutting. If the method of supporting the workpiece by the chuck can be used carefully and accurately, then Can get accurate results.
The Dongguan CNC processing plant can get very accurate results by supporting the workpiece between the two centers. One end of the workpiece has been machined, then the workpiece can be turned. Machining the other end on the lathe, the center hole serves as a precise positioning surface and a supporting surface that bears the weight of the workpiece and resists the cutting force. When the workpiece is removed from the lathe for any reason, the center hole will accurately return the workpiece to this lathe or another lathe or a cylindrical grinder. The workpiece is not allowed to be clamped on the main bearing by the chuck and the center of the lathe. However, the first thing that comes to mind is a method of quickly adjusting the workpiece on the chuck, but this is not allowed because it is impossible to be supported by the center of the lathe while being clamped by the chuck. The adjustment provided by the center of the lathe will not be continuous and the pressure of the claw will damage the center hole and the center of the lathe, and even the spindle of the lathe. Floating jaws provide an exception to the above statement. They are used almost exclusively for high-production jobs. These chucks are real job drivers and are not used for the same purpose as ordinary three-jaw and four-jaw chucks.
Dongguan CNC processing plant and large-diameter workpieces are fashioned in two centers. They are best to be clamped by the panel on the tail of the main bearing to smoothly obtain energy conversion; many lathe chucks cannot convert sufficient energy, although they can be used as special Energy conversion
