GRINDING FEEDS AND SPEEDS

Most cylindrical grinding machines offer a rather wide range of work rotation speeds, table traverse speeds, feed rates, and, sometimes, different wheel speeds as well. The proper selection of these variables, in combination with the choice of the grinding wheel, has a great bearing on the results and the economy of the grinding operation.

5 Grinding Considerations for Improving Surface Finish ...

Jan 26, 2021  In applications where the cycle time is not critical, reducing the feed rate might be a good option for improving the workpiece surface finish. When the wheel speed is increased and the depth of cut and feed rate are reduced, the wheel can become dull. This increases the chance of thermal damage to the workpiece and can increase grinding forces.

MACHINING TIPS: Critical Aspects to Grinding - Surface ...

Jan 11, 2017  For a cylindrical or surface grinder, the feed-rate is determined by the speed of the table. For a centerless grinder, the feed-rate is determined by the angle and rpm of the regulating wheel. For the grinding of most plastics, a suggested feed-rate is fourteen to thirty-two ft/min (4.27 to 9.75 m/min).

Basics of centerless grinding Cutting Tool Engineering

Dec 01, 2016  During grinding, the force of the grinding wheel pushes the workpiece into the regulating wheel and against the support. The regulating wheel determines the workpiece’s rotational speed. Tilt it a few degrees and the workpiece will be pulled through the wheels and out the back of the machine, a technique known as through-feed grinding.
