A surface grinder is a machine tool used to provide precision ground surfaces, either to a critical size or for the surface finish.
It is suitable for grinding ring parts, valve sheets, saw blades, milling cutters, etc., and machining precision machining. It can be widely used in the grinding of fine parts in auto parts factories, bearing factories, air compressor factories, and general machinery manufacturers.
Types of Surface Grinder
Horizontal-spindle (peripheral) surface grinder
The periphery (flat edge) of the wheel is in contact with the workpiece, producing the flat surface. Peripheral grinding is used in high-precision work on simple flat surfaces; tapers or angled surfaces; slots; flat surfaces next to shoulders; recessed surfaces; and profiles.
Vertical-spindle (wheel-face) grinders
The face of a wheel (cup, cylinder, disc, or segmental wheel) is used on the flat surface. Wheel-face grinding is often used for fast material removal, but some machines can accomplish high-precision work. The workpiece is held on a reciprocating table, which can be varied according to the task, or a rotary-table machine, with continuous or indexed rotation. Indexing allows loading or unloading one station while grinding operations are being performed on another.
Disc grinders and double-disc grinders
Disc grinding is similar to surface grinding, but with a larger contact area between disc and workpiece. Disc grinders are available in both vertical and horizontal spindle types. Double disc grinders work both sides of a workpiece simultaneously. Disc grinders are capable of achieving especially fine tolerances.
