Brand new About this product
The Electric Cylindrical Grinding Machine by National Cutting Tools is a high-precision grinding machine tool designed for external cylindrical grinding on shafts, precision pins, spindle blanks, and motor rotors. Turning operations on lathes leave tool marks and minor diameter variations; cylindrical grinding removes microscopic amounts of material to achieve mirror surface finishes (Ra 0.2 to 0.4 µm) and strict geometric tolerances within 0.002 mm. Built with a heavy cast-iron base that dampens wheel harmonics, the machine features a precision wheelhead driven by an electric motor, an adjustable workhead with variable speed control, and a smooth table traverse driven mechanically or hydraulically. Precision hydrodynamic or preloaded angular contact spindle bearings ensure vibration-free wheel rotation for superior roundness and cylindricity on hardened steel parts. Key Features Micron-Precision Wheelhead Spindle: Hardened alloy spindle rotating in precision hydrodynamic bearings delivers chatter-free grinding. Variable Speed Workhead: Regulates workpiece rotational speed to match workpiece diameter and grinding wheel grit specifications. Heavy Cast-Iron Base: Normalized graded casting provides massive thermal stability and absorbs wheel-balancing vibrations. Fine Infeed Micrometer Dial: Allows precision micro-infeed adjustments down to 0.001 mm for tight tolerance production. Swiveling Table for Taper Grinding: Graduated table swivels to allow precision taper grinding on tool shanks and machine tapers. High-Efficiency Coolant with Magnetic Separator: Keeps the grinding zone cool and removes metal swarf and abrasive grit from the fluid. Applications Precision external grinding of pump shafts, motor rotors, and machine tool spindles Grinding hardened pins, rollers, and hydraulic cylinder piston rods Automotive valve stems, camshaft lobes, and bearing journals Toolroom manufacturing of reamers, milling arbors, and mandrels Manufactured and tested at our Ludhiana works. Certified test grinding on customer sample shafts verifies roundness, cylindricity, and surface roughness before dispatch.
