Surface grinding machine working table (L x W) /
NSG-618 series: 470mm x 150mm
Main feature /
Table surface guaranty(Testing grinding piece*6, thickness difference) : 2μ.
Downfeed(minimum unit) : 0.1μ
■ Spindle & motor
Vertical driven by AC servo motor.
2HP V3 grade low virbration spindle motor.
Direct drive spindle, ABEC Class 7 (P4) bearings, 0.003m/m TIR.
3 angular contact ball bearings at front, 2 angular contact ball bearings at rear side of spindle.
■ Cross and Longitudinal(618TS)
Cross feed driven by simplified AC servo motor, it's more precise when intermittent feed.
Longitudinal by advanced table hydraulic design, feed range from 0.3m/min to 25m/min, it provides easy operation and vibration-free reversing motion and controlled by the proximity sensor built-in design for safety.
■ Cross and Longitudinal(618H)
Cross feed driven by ball screw (618H).
Longitudinal driven by hydraulic (618H).
■ Base & slide ways
Enlarged structure dimension, superior stability and rigidity.
Cross double V and longitudinal V& flat, and TURCITE B coated with hand scraped, 3 axes are box ways.
One-piece casting base and slide way.
All main castings are made of "Meehanite GC275" and have been annealed stress for long lasting and accuracy.
