Main Structure of Centerless Grinding Machines
They are cast of high grade FC-30 iron, melted by advanced induction furnace, then cast in resin cores. In order to ensure stability and rigidity, they are heat-treated with normalizing procedure prior to machining.

Precision ground Hydrostatic Bearings: Substantial decrease in heat deformationassociatedwith Hydrodynamic bearings.Minimal friction, lateral displacement, and pressure .Extended tool life under heavy cut loads.

Grinding Wheel Spindle: The Grinding Wheel Spindle runs on hydrostatic bearings with a high pressure oil film for added precision under heavy loads. Substantially reduces wear while prolonging spindle trueness. SNCM-210H carbon steel hardened beyond HRC60, yielding high torsion resistance.

The machine body is designed for both conventional as well as CNC machines. Double Feed axis and Double slides design are easily accomplished with automatic and computerized Numerical Control (CNC) System. This enables it to eliminate the trouble caused by former single feed axis while CNC and automated.
