But in general, honing stones are able to produce finishes as smooth as Ra 10, while grinding wheels used to achieve material removal will have a rougher finish. Whether you are grinding or honing the ID, the tube must be held. That means both of these internal grinding processes are limited in how small the diameter of the tube can be.

A road map for grinding and finishing stainless steel. A prime example is a stainless part with a good-looking gas tungsten arc weld that only needs to be blended and matched to the base material's finish pattern. Grinding Strategies A grinder with a low-removal-rate grinding wheel can face significant challenges working with stainless steel ...
5 Grinding Considerations for Improving Surface Finish, 20-08-2021 0183 32 Poor coolant filtering can also negatively affect the surface finish and/or cause scratches on the part surface If particles are not filtered out, they can be pumped back into the grinding zone along with the coolant When filtering is suspected as the cause of scratches and poor finish, a smaller …
Adjusting the grinding parameters can be the easiest and fastest solution to improve a part's surface finish. Here are the key parameters and recommended actions to do it successfully. Creepfeed/surface grinding: Increase wheel speed. This is a good starting point. However, be sure the wheel is rated to run at the new speed.
Apex grinding machines are designed with a high tolerance level, allowing for precision up to 0.02 mm. Polishing and Finishing. Finishing and polishing metal is the process of refining the surface to a finer finish by using various grits of abrasives. Polishing can be obtained using either a wet or dry process.

Jan 22, 2019 With OD grinding, there are limits on how small a part can be and still be ground this method. That is because on parts of 0.250" (6.35 mm) or smaller, it is extremely hard to find the true center. In fact, it is the difficulty of finding the center on very small parts that led to the development of centerless grinding.
Improving surface finish can be done by making adjustments to one or more of these points: operational parameters, wheel dressing, grit size, coolant delivery and machine condition.
