Precision Universal Grinding Machines

Description: Precision Universal Grinding Machines manufactured by our company are available in two main models- Models 200 and 260. These machines could be fully or semi automatic. The hydrodynamic spindle assembly of the machine is housed in a closely grained cast iron work head body. The spindle is made up of alloy steel thoroughly hardened, ground and stabilized to finest accuracy (roundness accuracy is 0.0005 mm). Work head has facility of both live and dead centres grinding applications. The wheel head like work head is having CI body and has hydrodynamic spindle assembly for rigidity, accuracy and longer life. In-feed system of the machine has preloaded precision linear guided way bearings for strick-slip free motion for higher repetitive accuracies. The machine's tail stock has sleeve moving on preloaded brass ball bearings and has an adjustable spring load pressure to suit varying requirement of grinding. The diameter of the heavy duty precision internal grinding is 60 x 250/80 x 250 mm. These machines are optionally supported with features like frequency spindles with oil mixed lubrication and external cooling. The automatic machine models have complete auto grinding cycle, with rapid approach - coarse feed - fine feed - spark out and rapid reversal - auto wheel dressing. The semi-automatic machine models have rapid approach with hydraulic table travel.
