Chapter 17: Grinding Methods and Machines
Centerless grinding Centerless grinding machines eliminate the need to have center holes for the work or to use workholding devices. In centerless grinding, the workpiece rests on a workrest blade and is backed up by a second wheel, called the regulating wheel. The rotation of the grinding wheel pushes the workpiece down on the workrest blade ...
What is Centerless Grinding? | The complete guide to the process
Centerless grinding is a process that has been a part of manufacturing for nearly 100 years. It helps solve one of the limitations of other types of turning machines such as lathes and mills. The process is better suited to deal with the limitations imposed on lathes and mills with respect to the size, material type, and finishes of different ...
