Grinding of Large dia:

• In order to work on grinding of large diameter, bearing width and high stock removal from the CR pin, we suggest the use of grinding equipment, which is placed on the fillet radius of the Pin as reference for the grinding stone.
• The machine rotates around the Crank Pin at lower RPM and the grinding is carried out by pneumatic grinder operating with suitable grinding stone. This process is recommended only if radius profile is not worn out.
