Centerless grinding is a machining process where the workpiece is held between two grinding wheels rotating in the same direction but at different speeds. The grinding wheel, which is stationary and rotates at a higher speed, is responsible for the grinding action with abrasive grains bonded to its surface to remove material from the workpiece. The regulating wheel, movable and positioned at an angle, rotates at a slower speed and applies lateral pressure to control the rotational speed of the workpiece, providing better grip.
In through-feed grinding, the workpiece is fed through the grinding wheels, entering on one side and exiting on the opposite. The regulating wheel’s cant angle provides the lateral force needed for this continuous feeding. This method is efficient and simple, suitable for cylindrical parts with consistent diameters. However, it is limited to simple shapes and may require other grinding types or additional operations for more complex shapes. Overall, through-feed centerless grinding is efficient, easy to set up, and ideal for consistent cylindrical parts.
