The dynamic column structure, user-friendly control, and a perfect combination of precision and stability can fully meet the needs of precision grinding. five μ Planar accuracy/1 μ Up-down feed/0.02Ra surface roughness
Main feature /
■ Accuracy
Table surface guaranty(Testing grinding piece*6, thickness difference) : 5μ
Downfeed(minimum unit) : 1μ
■ Spindle & motor
Vertical driven by AC servo motor.
15HP V3 grade low virbration spindle motor.
Direct drive spindle, ABEC Class 7 (P4) bearings, 0.003m/m TIR.
4 angular contact ball bearings at front, 2 angular contact ball bearings at rear side of spindle.
■ Cross and Longitudinal
Cross feed driven by simplified AC servo motor, it's more precise when intermittent feed.(TS)
Cross feed driven by AC servo motor. (P)
Double hydraulic cylinders drive with variable speed regulator for longitudinal.
Longitudinal by advanced table hydraulic design, feed range from 0.5m/min to 25m/min, it provides easy operation and vibration-free reversing motion and controlled by the proximity sensor built-in design for safety.
■ Base & slide ways
Linear guide ways for vertical and cross axes with extra large block.
Longitudinal double V, and TURCITE B coated with hand scraped
One-piece T shape casting base and slide way.
All main castings are made of "Meehanite GC275" and have been annealed stress for long lasting and accuracy.
