Grinding Machines, Double Disc Type

Amolik Precision Machines has developed double disc grinding machines to grind two opposite surfaces simultaneously to get high degree of parallelism and surface finish within close dimensional tolerance. The machine consists of two heavy duty spindles driven by separate motors and mounted on matched pairs of high precision preloaded angular contact spindle bearings for maximum rigidity. Spindles are of hollow design for the flow of coolant through the spindle as this is essential when grinding thin components. The spindle movement is on V-shaped needle-cage linear guide system to ensure very accurate feeding free from any stick-slip. Efficient cooling system with filtration, diamond dressing unit, lubricating system and safety guards are provided to ensure high quality of grinding. Grinding wheel changeover is quick nd easy. Spindle heads can be swivelled to ± 1° to facilitate accurate setting. Standard and heavy duty versions are available for high output and heavy stock removal. Both ferrous and non-ferrous material can be ground with equal ease. A dimensional tolerance of ±10 microns with parallelism of 5 microns can be achieved easily for smaller and medium size components. It is suitable for grinding a range of components like bearing rings, rollers/needles' ends, piston rings, piston pins, connecting rods, engine valves, etc. Machines are custom-built for manual, semi and fully automatic operation and available in grinding wheel diameter from 250 mm to 1004 mm to suit end-users' requirements.
