For the machining and production process of precision parts of machine tools, it is very common to have some small defects. Although some small defects will not have much impact on the entire production process, if they occur during the entire production process, their work efficiency may be compromised. The rotary center plays a very important role in the machining of the workpiece, and the rotary center can be rotated and then inserted with the center to make the machine run more smoothly.
The function of the center is to center and bear the weight of the workpiece and the cutting force of the tool on the workpiece. The center has a front center and a rear center. The front center is inserted in the spindle taper hole to rotate with the spindle; the rear center is inserted in the tailstock sleeve. For example, the turning of the long shaft is to install the workpiece on the two centers.
There are two types of center, fixed center and rotary center, and rotary center can be divided into light rotary center, medium rotary center, cone rotary center and insert rotary center.
The light-duty revolving center is suitable for high-speed, light-load precision parts processing, and has two kinds of ordinary precision and high precision.
The medium-sized rotary center is suitable for processing with medium cutting load, and has two kinds of ordinary precision and high precision.
The cone-shaped revolving center is mainly used for processing pipe sleeve parts, which can withstand higher loads.
The plug-in rotary center has 5 center plugs with different shapes. The center plugs can be selected according to the different conditions of the workpieces processed by the precision parts.
