A surface grinder is a precision machine tool that utilizes a high-speed rotating grinding wheel to remove excess material from the surface of a workpiece; it is primarily used to machine flat, contoured, and profiled surfaces on materials such as metal, glass, or ceramics. Its core function is to ensure the workpiece achieves exceptional dimensional accuracy, flatness, and surface smoothness, making it widely used in precision manufacturing sectors such as mold making, automotive engineering, and aerospace.

These machines primarily use a rotating grinding wheel to grind workpieces to the required flatness. They are categorized based on table shape into rectangular-table and rotary-table types; the main specifications for rectangular-table surface grinders are table width and length, while for rotary-table grinders, the key parameter is the table diameter. They are also classified by spindle orientation into horizontal-spindle and vertical-spindle grinders; double-disk surface grinders likewise come in both horizontal- and vertical-spindle configurations.
