All main structure including machine base, column, saddle, head, etc are made of high quality FC30 casts iron, applied finite element CAE method to the analysis of casting optimization, to achieve high stability, rigidity and avoid deformation.
Rotating table adopted by hydrostatic bearing system with servo motor, reduction motor and pulley for heavy grinding application assures superior rigidity, low friction coefficient, no temperature rising and deliver long lasting performance.
Vertical axis is driven by precision ball screw with AC servo motor, supported by linear guide ways and column in double-layers structure for excellent smooth movement.
Cross axis is driven by AC servo motor, supported by linear guide ways, to ensure accurate movement.
The Flange type spindle is supported by super precision angular contact ball bearings #P4, to deliver high positioning accuracy up to 0.002mm.
The grinding wheel dresser is mounted at the back, out of working table, that assures superior reliability. Auto dressing cycle easily be preset setting thru user interface: auto dressing and compensating.
Adopts Mitsubishi PLC controller, graphical user interface with Mitsubishi color touch screen, easy to learn and operate.
Electrical cabinet and operation box are superior design and arrangement for user convenience. MPG is standard equipped to increase work efficiency.
