This usually involves grinding the OD slightly higher than the finish grind OD to ensure the correct finish size. Electrochemical grinding is a type of grinding in which a positively charged workpiece in a conductive fluid is eroded by a negatively charged grinding wheel.
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.

Rod mills are used to make metal rods, while semi-autogenous grinding (SAG) mills and autogenous grinding mills smooth copper, gold, platinum, and silver. Metal Vibratory Finishing Vibratory finishing machines are used to deburr products and remove sharp edges.
"Snagging" means grinding which removes relatively large amounts of material without regard to close tolerances or surface finish requirements. 1910.211(b)(11) "Off-hand grinding" means the grinding of any material or part which is held in the operator's hand.
Fine grinding, by definition, is the blending of the weldment to the surface of the metal for a smooth, consistent, and attractive appearance. When working on stainless steel grades, whether for appliances, structural parts, sheet metal housings that are visible on the finished product without being ...
Surface finish can then be described by using the roughness average (Ra) parameter. The Ra value is defined as the average value of the departures from its centerline through a prescribed sampling length.
3. Sports To score a goal as the last maneuver in a play: a good forward who just can't seem to finish.
finish obtained through grinding can be up to ten times better than with either turning or milling. Grinding employs an abrasive product, usually a rotating wheel brought into

Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.

Sometimes conching and refining can happen at the same time, but they do not have to and often you do not want them to. Some definitions are probably in order. Conching Conch comes from the Spanish word concha, which means shell.
Finish boring or internal grinding may do the job, but spindle deflection, variation in hardness of the material, and difficulties in precise workholding make the work slow and the resuits uncertain. Honing, because it uses rectangular grinding stones instead of circular grinding wheels, can correct these irregularities.
