Brand new About this product
The Universal Cylindrical Grinding Machine by National Cutting Tools is a versatile, high-precision grinding machine engineered to perform external (OD) grinding, internal (ID) grinding, face grinding, and taper grinding on a single platform. In precision engineering shops and toolrooms, purchasing separate internal and external grinders is expensive; our universal grinder incorporates a drop-down internal grinding spindle and a swiveling wheelhead to handle all cylindrical geometries. Built with a heavily ribbed cast-iron base, the machine features a swiveling workhead (up to 90 degrees), a swiveling table for taper grinding, and a dual-spindle wheelhead. The external spindle uses hydrodynamic bearings for vibration-free shaft grinding, while the high-speed internal spindle rotates up to 18,000 to 24,000 RPM for grinding deep precision bores and bearing sleeves with exceptional roundness. Key Features Dual External & Internal Grinding: Hinged internal grinding attachment swings down quickly into working position without removing the main wheel. Swiveling Workhead & Table: Both workhead and table swivel on graduated scales, enabling steep taper and face grinding operations. High-Speed Internal Spindle: Precision high-frequency spindle delivers 18,000+ RPM for smooth, chatter-free bore grinding. Hydrodynamic Main Spindle: External wheel spindle runs on precision hydrodynamic or Class P4 bearings for Ra 0.2 µm surface finish. Smooth Hydraulic Table Traverse: Infinitely variable table speeds with adjustable shock-free stroke reversal stops. Internal Coolant Delivery System: Separate coolant delivery paths for external flood cooling and deep-bore internal grinding. Applications Internal and external grinding of machine tool spindles, sleeves, and collars Boring and OD grinding of hardened bushings, gears, and bearing rings Grinding steep tapers on lathe centers, collets, and toolholders Pump cylinder bore and piston rod finishing in hydraulic equipment plants Built under strict ISO 9001:2015 quality standards at our Ludhiana works. Certified trial grinding for both internal and external geometries is completed prior to factory dispatch.
