Internal Grinder

An internal grinder is a type of grinder that grind the inner surfaces of cylindrical workpieces. Unlike external grinders that focus on the outer surfaces of objects, internal grinders complete accurate and smooth finishes on the interior of cylindrical components. The grinding operation is accomplished by using a rotating abrasive grinding wheel that removes material from the inner surface of the workpiece. The grinder's setup allows for controlled movement of the grinding wheel and the workpiece to achieve the desired dimensions, surface finish, and geometric accuracy.

GI150 series (STNinja 100) is CNC controlling 2 axes of table left, right feed and grinding wheel federate. It applies linear guide that enables fine feed. Its applications include crankshaft journals, helicopter engine turbine blades, pump parts, and more. Internal grinders are commonly used in various industries, including manufacturing, aerospace, automotive, and precision engineering.
