CNC Grinding Defined

Cylindrical Grinding: Is a precision machining process used to shape the outside diameter (OD) or inside diameter (ID) of a round workpiece using a rotating grinding wheel.
Grinding Wheel: A precision cutting tool made of abrasive grains bonded together, used to remove material from a workpiece through abrasion.
Workhead: The machine component that holds and rotates the workpiece during the grinding process.
Tailstock: A movable machine component located opposite the headstock that supports the end of a workpiece during machining operations.
Workpiece: The raw material or partially finished part that is being machined, cut, shaped, or ground during a manufacturing process.
Wheel Arbor: The shaft or mounting spindle that holds and secures a grinding wheel onto a grinding machine.
Disc Dresser: A tool used to dress (reshape and clean) the grinding wheel to maintain its cutting efficiency and accuracy.
Studer Grinder: Swiss-built precision grinders known for their rigid construction, advanced CNC controls, and consistent accuracy and repeatability.
