A surface grinder is a type of grinding machine. It primarily uses a rotating grinding wheel to grind workpieces to achieve the required flatness. Based on the shape of the worktable, they can be divided into rectangular and circular worktables. The main parameters of a rectangular worktable surface grinder are its width and length, while the main parameter of a circular worktable is its diameter. Based on the type of shaft, they can be divided into horizontal and vertical spindle grinders. Examples include the M7432 vertical spindle rotary table surface grinder and the 4080 horizontal spindle rectangular table surface grinder.
