MY820
Standard features: * High rigidity H-frame column with spindle center to table for extra clearance under the wheel. * Enhanced ribbed full cast iron base provides the best anti-vibration foundation with greater stability and rigidity *Enlarged spindle housing for heavier grinding * V3 grade spindle motor for powerful output to achieve prescicion work standards and better grinding capability. * Cartridge spindle w/4 preloaded class 7 (P4) bearing and run our of taper nose better than 0.00060 T.I.R.provides quiet,vibration free operation for better workpiece accuracy. * MY820: X –axis auto hydraulic transmission,Y – axis manual transmission,Z – axis manual transmission. * Flat+V type linear table ways for easy and smooth longitudinal movements and double V shape saddle ways for rigidity * Manual lubrication system provides lubrication to all necessary mechanism saddle&column ways,bearings and lead screws for better machine performance and less maintenance. * Convenient control panel including all buttons and switches. *Digital readout system – two axis (Z& Y axis) digital readout The min.digital readout amount:0.001-0.005mm Standard Appendix:
