Center-Type Grinding Review. In Center-type grinding, the part is secured between two pointed cone shaped center, as in a lathe. The part may also be secured into the grinding machine using chuck, or a faceplate. The grinding wheel rotates about an axis parallel to the part and is feed perpendicular into the part surface requiring grinding.
3. Grinding methods differ in how parts are fed through the machine. The primary difference between the two most commonly used methods of centerless grinding is in how the workpieces are fed through the machine. Through-feed grinding is typically used for parts with consistent roundness across the length of the part. In this method, the ...

Grinding you may want a 3hp or larger spindle motor so to pull perhaps a 1 1/2" (or wider) wheel. Running one leg with down feed and long travel you would be best served with the widest stack of parts. With a 1 1/2 wide wheel you might run 15-16 parts a 2" wheel 20-21. Up side: Rough grind one leg, skim dress and skim grind that leg.
Centerless Grinding. Capacity: 3" Diameter, 4" Length. Centerless grinding is an effective method of grinding the outside diameter of any round parts that do not have centers in each end.

The workpiece is ground between centers. This step grinds the desired diameters of the workpiece concentric with the centers at a cutting rate from 0.05 mm/min. to 0.10 mm/min. (0.002 ipm to 0.004 ipm). Following sparkout, the grinding wheel retracts, and the regulating wheel is infed. It forms a prism relative to the workrest blade.
