A cylindrical grinding process finishes most wheel spindle surfaces. It is essential that this grinding process leave a surface finish that is smooth and free of defects with minimal runout. No grinder produces a perfect surface. Grinder wheel runout, improperly dressed wheels and fixture vibrations can cause chatter on the spindle surface finish.
Steel surface finishes are often an important aspect of custom machine parts. Sometimes steel surface finish is also referred to as surface texture or Surface Roughness. The surface finish of a machine part may be important to reduce friction with other machine parts or to improve the aesthetics of the part.
