Grinding Capabilities

Grinding is a precision abrasive machining process that uses a rotating grinding wheel to remove material from a workpiece. The grinding wheel consists of abrasive grains (aluminum oxide, silicon carbide, CBN, or diamond) bonded together in a matrix. Grinding is typically used as a finishing operation after heat treatment, achieving tolerances that are difficult or impossible with conventional machining. Types of grinding include surface grinding (flat surfaces), cylindrical grinding (round parts), centerless grinding (high-volume round parts), internal grinding (bores), and creep-feed grinding (deep profile cuts). Grinding is essential for producing precision gears, bearings, shafts, cutting tools, and any component requiring tight tolerances and smooth surfaces.

Tolerances:
±0.0001"-±0.0005" (±0.003-0.013mm) achievable
Lead Time:
3-10 business days
Cost Range:
$75-$175/hour; $20-$500+ per part

Grinding in Ann Arbor — FAQ

How many Grinding providers are in Ann Arbor, MI?

The Ann Arbor metropolitan area has approximately 400 manufacturing establishments, many of which offer grinding services. The area employs about 12,000 manufacturing workers, ensuring a skilled workforce for your project.

When is grinding necessary?

Grinding is necessary when parts require tolerances tighter than ±0.001", surface finishes better than 32 Ra microinches, or when material is too hard for conventional machining (heat-treated steel above 40 Rc). It is a finishing process, not a bulk material removal process.

What surface finish can grinding achieve?

Grinding achieves surface finishes of 4-32 Ra microinches (0.1-0.8 Ra μm) depending on the process and parameters. Mirror-finish grinding can achieve 1-2 Ra microinches. This is significantly smoother than as-machined surfaces (32-125 Ra).

What is centerless grinding?

Centerless grinding supports the workpiece between a grinding wheel, a regulating wheel, and a work rest blade — without centers or chucks. It is extremely efficient for high-volume production of cylindrical parts like pins, shafts, rollers, and needles.

Can grinding replace other machining operations?

Creep-feed grinding can perform deep cuts similar to milling, useful for hard materials. However, grinding is generally used as a finishing operation after turning, milling, or heat treatment. It is rarely the most efficient process for bulk material removal.
