Grinding surfaces
Mark the external diameters and lengths to be ground, adjacent shoulders and the datums used to locate each surface. Distinguish ground surfaces from areas that can remain turned. Include the condition of the incoming part when requesting a grinding operation.
Dimensions & surface
Specify diameter tolerances and surface roughness with their units and applicable standard. Add roundness, cylindricity or runout requirements where relevant, together with reference datums. These callouts help define how the finished surface will be inspected.
Material condition
State the material grade, heat-treatment condition, hardness and quantity. For an already machined blank, provide its current dimensions and available grinding allowance. We review the stock condition and requested finish before confirming the grinding route.
Manufacturing feasibility, tolerances and inspection requirements are reviewed for the individual project.
