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.

Grinding in Atlanta — FAQ
How many Grinding providers are in Atlanta, GA?
The Atlanta-Sandy Springs-Alpharetta metropolitan area has approximately 1,800 manufacturing establishments, many of which offer grinding services. The area employs about 38,000 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.
