M820A Manual surface grinding machine
Main Features:
* 3 – axis manual operation
* 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.
* M618: roller steel balls on linear table ways for easy and smooth longitudinal movements and “V+Flat” shape saddle ways for rigidity.
* Mid-level downfeed handwheel placement for convenient and easy positioning for Z-axis
* 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
