Internal / 3 axis

SUPERTEC’s CNC three axis grinder – STNinja Series (GrindMaster Series) is the best solution for the complex grinding process. The closed-loop linear scale feedback system design of the X-axis ensures the high precision requirement for grinding operation. Automatic Sizing devices and a touch probe can be added to improve accuracy even more.Imagine having a grinder that can handle all your complex grinding needs with ease. Our 3-Axes Complex CNC Internal Grinder utilizes a Computer-aided Numerical Controller to control the workhead (X-axis), ID/OD wheelhead (W-axis), and ID wheelhead (Z-axis). With its one-time chucking action, this series can complete complex and precise grinding operations, including internal diameter, outside diameter, shoulder grinding, taper grinding, and end-surface grinding. It is applicable for automotive, machine tool, aerospace, hydraulic, pneumatic, and electric motor industries. It not only reduces costs but also improves surface accuracy, productivity, and efficiency.Check out our product below and feel free to contact us for a quote or further details.

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.As a leading internal grinder manufacturer, SUPERTEC delivers excellence in both machine quality and customer service.
