Original keys and centerless grinder

Definition of centerless grinder
A centerless grinder usually refers to a centerless cylindrical grinder. The workpiece does not need center centering and support but is placed between the grinding wheel and the guide wheel. The centerless grinding method is used to grind the rotating surface of the workpiece. The grinder consists of a supporting plate and a The grinding wheel supported by the guide wheel is generally installed at the end of the main shaft. If the width of the grinding wheel is greater than
mm, the grinding wheel is installed in the middle of the main shaft. The maximum width of the grinding wheel can reach
mm. The grinding wheel rotates at high speed for grinding, and the guide wheel rotates in the same direction at a slower speed, driving the workpiece to rotate for circular feed. During through grinding, axial feed is achieved by adjusting the slight inclination angle of the guide wheel axis. It is suitable for grinding slender cylindrical workpieces, short shafts without central holes, and sleeve-type workpieces. During plunge grinding, radial feed is achieved through the movement of the guide wheel frame or grinding wheel frame. It is suitable for grinding workpieces with shoulders or bosses, as well as cones, spheres, or other workpieces with curved lines. Centerless grinders have high productivity and are easy to automate with various loading and unloading devices. They are mostly used for mass production and can be operated by less skilled workers. The grinding accuracy of a centerless grinder is generally
microns for roundness and
microns for dimensional accuracy. High-precision centerless grinders can reach
microns and
microns respectively. In addition, there are centerless internal cylindrical grinders and centerless thread grinders.
