Hard turning and grinding of AISI 52100 steel was conducted using gentle machining conditions. Surface integrity was then analyzed in terms of surface finish, microstructure, and surface and subsurface micro and nanohardness. Hard turning may produce equivalent or better surface finishing compared with grinding.

Grinding or finishing at an angle that is too steep may cause you to work much harder than necessary since you're not getting the full benefit the product is designed to provide. When using cutting wheels, hold the tool at a 90-degree angle, perpendicular to the workpiece. This position enhances safety and helps improve wheel life and cut rate.

When measuring in a parallel direction, the average surface finish was 3.3 microns Ra before grinding and 0.21 microns Ra after grinding (Figure 7). When measuring perpendicular to the grind direction the surface finish was an average of 2.1 microns Ra before grinding, and as low as 0.5 microns Ra after grinding (Figure 8).

Superfinishing is a chip removing machining process. But not one that is comparable to any other. In contrast to the classic lathe turning and grinding methods, there is full surface contact between the tool and the workpiece. This is precisely the feature that produces the unique characteristics of a perfectly machined surface.
