Design and fabrication of an automatic grinding machine

Grinding is one of the most important manufacturing process for high precision parts. Grinding characterized by low material removal rate and high surface finish is an abrasive machining process. Geometrically undefined grits of grinding wheel influences part surface finish. Cutting edges worn out during grinding are retained by timely dressing.

5 Grinding Considerations for Improving Surface Finish

However, be sure the wheel is rated to run at the new speed. The maximum operating speed (MOS) will be stated on the side of the wheel. Reduce feed rate. Reduce depth of cut. Increase the number of spark-out passes. This component is ground to a surface finish of 3.0 microinch Ra.

What Is Grinding and Its Working Principle and Type?

During the grinding process, the grinding surface of the grinder tool is evenly coated with abrasive. If the material hardness of the grinding tool is lower than that of the workpiece, when the grinding tool and the workpiece move relative to each other under pressure, the abrasive has sharp edges and corners. ... The surface grinding machine ...

Grinding and Polishing

grinding machine gage is usually the incoming air pressure, which is not necessarily equal to the pressure of the specimens against the platen. Perforated or grooved platens are available that aid in the re-moval of swarf. Experiment with the abrasive size, contact pressure, relative rotation directions (same or opposite), and frequencies shown
