Internal cylindrical grinding operates somewhat like a boring operation. The work-piece is usually held in a chuck and rotated to provide surface speeds of 20 to 60 m/min (75 to 200 ft/min) [16].Wheel surface speeds similar to external cylindrical grinding are used. The wheel is fed in eitheroftwo ways: traverse feed, Figure 25.9(b), orplunge feed. . Obviously, the wheel diameter in internal ...

A larger abrasive grinding wheel; The beauty of centerless grinding is that the workpiece is held in place by the pressure of the rotating wheels. No fixturing is required, so the setup is simple and turnaround times are fast. And because the workpiece is rigidly supported, there is no deflection during the grinding operation.
