Surface grinding is used when a machined face needs tighter flatness, parallelism, thickness or roughness than practical milling alone can provide. It is commonly planned after heat treatment so distortion can be removed from functional faces.
The process route must leave enough stock for heat-treatment movement and cleanup without sacrificing finished dimensions. Too little allowance can leave scale or low areas; too much adds heat and cycle time. Datum faces and grinding sequence should be agreed before rough machining.
Height comparators, micrometers, indicators on a surface plate and CMM checks may be combined depending on the drawing. Flatness, parallelism and thickness are different requirements and need separate acceptance criteria. Roughness targets should be specified with the required measurement direction and cutoff.
Provide controlled 3D and 2D data, material and condition, quantity, finish, critical characteristics, inspection documentation and target delivery. State any approved alternatives or supplier restrictions.
Tolerance is reviewed by feature against size, geometry, material, setup, process sequence and measurement. The quotation records assumptions; it does not extend one tight value to every dimension.
Selected dimensional reports, first-article records or material documents can be included when the required scope and format are stated before quotation.
Not necessarily. Machine ownership and partner-supported processes are distinguished during capability confirmation where they affect confidentiality, quality or delivery.
