R-Grind HD
High-performance Cylindrical Grinder for accurate production of large-work pieces such as car axles, hydraulic cylinders, etc. Built with high-quality Meehanite cast iron with heavy ribbing ensures high overall stiffness, even with heavy workpieces. A precision grinding spindle bearing ensures the highest accuracy. The belt-driven spindle stock with adjustable speed ensures continuous optimal conditions for grinding. Automatic lubrication of the headstock is standard on all models of these Cylindrical Grinders. Hydraulically driven table feed with softstop at the end of the movement. All feed rates are infinitely variable ensuring a high quality surface finish. Rapid approach/withdrawal of the grinding wheel. Hydrostatic bearing of the spindle and tailstock.
The 31″ grinding capacity is matched with 117″, 136″, or 156″ between centers and a max workpiece weight of 4,400 pounds. A 20 Hp spindle motor gets your spindle speed up to 1100 rpms. The transverse feel is 0.04″/rev with 0.0002″ increments. Both the headstock and tailstock tapers are MT6.
