A centerless grinding machine is a grinding machine that uses a centerless grinding method to grind the rotating surface of a workpiece, usually a centerless cylindrical grinding machine. On a centerless cylindrical grinder, the workpiece does not need to be centered and supported by the top, but is placed between the grinding wheel and the guide wheel, and is supported by the pallet and the guide wheel.
The main reason is the high productivity. It is easy to realize automation after various loading and unloading devices. Most of them are used for mass production and can be operated by unskilled workers. The grinding accuracy of centerless grinders is generally: roundness of 2 microns, dimensional accuracy of 4 microns, high-precision centerless grinders can reach 0.5 microns and 2 microns, respectively. In addition, there are centerless internal grinding machines and centerless thread grinding machines.
The centerless grinder can automatically dress and compensate automatically. The guide wheel feed guide is a double V-shaped needle roller guide wheel, which is fed by a servo motor and can compensate each other with the dressing of the grinding wheel. The machine tool is equipped with an automatic loading and unloading mechanism, which can carry out automatic cycle grinding, which greatly improves work efficiency compared with traditional grinders.
