without any action roundness in grinding

Centerless Grinding: Not Magic! | Modern Machine Shop

Centerless grinding, if set up properly, will achieve roundness, surface finish and dimensional tolerances that are among the best available in metalworking. Moreover, the process is able to improve the roundness of out-of-round workpiece blanks.

Centerless Grinding Gives Steel Precision Roundness

Centerless grinding is also often considered a kind of cleaning operation, one that can revive and recycle a junk steel bar or any round, steel material. With the abrasive teeth on the precision grinding wheels, the rust on the steel’s surface is easily scraped away in a continuous turning motion, resulting in a steel bar that is shiny and good as new.

Centreless Grinding Troubleshooting

When through-feed grinding relatively short work, without using a loading device, do not use fingers to push work between wheels. Use a piece of wood dowelling or other suitable strip. When in feed grinding, without using an automatic loading device, construct a sheet metal guard on workrest so operator’s fingers are protected from wheels.

8 Principles of Centerless Grinding

 · Through-feed grinding is typically used for parts with consistent roundness across the length of the part. In this method, the workpiece travels along the rest blade between the two wheels. Driven by a slight angle applied to the regulating wheel relative to the grinding wheel, the through-feed method basically “squeezes” the workpiece across the grinding wheel and out the other side.
