Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer (µm) (4 x 10-5in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry ...

The result with conventional grinding is poor surface texture and parts that break easily. This led to research to determine permissible cutting depths to avoid such problems. It was shown that plastic grinding behaviour can be achieved at very small cutting depths employing very fine abrasive. This is the basis for ultra-precision grinding.

Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle ), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.).
