Bore geometry
Provide the finished diameter, depth, entry geometry and any internal shoulders or reliefs. State whether the bore is through or blind and show interruptions in the ground surface.

Cylindrical ID grinding for precision bore requirements. Request a quote for the internal dimensions, surface finish and feature relationships specified on your component drawing.

Your component / Your application
ID grinding uses an abrasive wheel inside the component to finish an internal surface. Bore access and the reach of the grinding tool are important considerations when reviewing the operation.
For an internal-grinding operation or a complete component, include a section view that shows the bore and related features. Through bores, blind ends and interruptions present different access conditions; the full geometry helps define the work included in your quote.
01 / Drawing detail
Provide the finished diameter, depth, entry geometry and any internal shoulders or reliefs. State whether the bore is through or blind and show interruptions in the ground surface.
02 / Drawing detail
Identify the reference surfaces and required relationship to outside diameters or end faces. Include the applicable drawing controls rather than relying on a general description of alignment.
03 / Drawing detail
Specify finish requirements, material condition and starting dimensions. Include any restrictions on edge breaks, internal corners or surfaces that must remain untouched.

Your quote confirms the manufacturing scope, pricing and delivery timing.
Common questions
Depth affects tool reach and access. The grinding tool must reach the required surface, and its support must suit the operation. A bore diameter alone does not communicate those conditions.
They are different finishing processes. If your specification requires one, identify it. If the method is open, send the geometry and finished requirements so the team can review the appropriate scope.
