Application of centerless grinding method grinding machine grinding a workpiece surface of revolution, usually centerless cylindrical grinding machine. In the centerless cylindrical grinding machine , the workpiece is not centered and supported, but placed between the grinding wheel and the guide wheel , supported by the pallet and the guide wheel. The grinding wheel is usually installed at the end of the main shaft, and the grinding wheel with a width of more than 250 mm is installed in the middle of the main shaft. The maximum width of the grinding wheel is 900 mm. The grinding wheel rotates at high speed for grinding , and the guide wheel rotates in the same direction at a slower speed to drive the workpiece to rotate for circumferential feeding. Through the grinding, the axial feed is realized by adjusting the slight inclination angle of the guide wheel axis, and is suitable for grinding the elongated cylindrical workpiece, the short shaft without the center hole, and the sleeve type workpiece. When cutting into the grinding , radial feed is achieved by the movement of the guide wheel frame or the grinding wheel frame , which is suitable for grinding workpieces with shoulders or bosses, as well as cones, spheres or other workpieces whose curves are curved. Centerless grinding machines have high productivity, and are easy to automate with various loading and unloading devices. Most of them are used for mass production and can be operated by less skilled workers. Centerless grinding machines generally have a grinding accuracy of 2 microns and a dimensional accuracy of 4 microns. High-precision centerless grinding machines can reach 0.5 microns and 2 microns, respectively. In addition, there are centerless internal grinding machines and centerless thread grinding machines .
　　 Centerless grinders are automatically trimmed and automatically compensated. The guide roller feed guide is a double V -type needle roller guide wheel, which is fed by a servo motor and can compensate with the dressing of the grinding wheel. The machine is equipped with an automatic loading and unloading mechanism for automatic cycle grinding.
