Grinding for Custom Machined Parts
Grinding as a finishing operation within a reviewed manufacturing process. Our retaining-screw case shows the actual setup and work on a heat-treated replacement component.

After machining and quenching and tempering, the 42CrMo retaining screw underwent grinding before inspection. Grinding was also used to finish and level the upper surface. The photographs show the setup and the operation rather than a stock illustration.
Agree the surface and its function
For a new part, identify which surface requires finishing and how it relates to mating components. Include the material, heat-treatment condition and the dimensions or surface requirements already specified. These inputs help us review whether the proposed operation suits the part.
Keep the inspection evidence in context
The case includes a finished-part micrometer reading of 14.994 mm and explains the reconstructed reference dimension. It does not establish a general grinding tolerance, surface roughness grade or machine accuracy rating. Inspection requirements for your project should be agreed during quotation review.
