Undoubtedly, the Yuqing APS-P series surface grinder is your wise choice. The X-axis of this series of models is driven by oil pressure, while the Y-axis and Z-axis are driven by servo. Its design philosophy is to help customers create profits.
Main feature /
■ Accuracy
Table surface guaranty(Testing grinding piece*6, thickness difference) : 2μ(618/818), 3μ(12xx/16xx series), 5μ(1640)
Downfeed(minimum unit) : 1μ
■ Spindle & motor
Vertical driven by AC servo motor.
2HP V3 grade low virbration spindle motor.(618/818)
5HP V3 grade low virbration spindle motor.(12xx series)
7.5HP V3 grade low virbration spindle motor.(16xx series)
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 and longitudinal are driven by servo motor.(S)
Cross driven by servo motor and longitudinal driven by hydraulic.(P)
Longitudinal by advanced table hydraulic design, feed range from 1m/min to 25m/min, it provides easy operation and vibration-free reversing motion and controlled by the proximity sensor built-in design for safety.(P)
■ Base & slide ways
Linear guide way with extra large block for vertical axis.
Cross double V and longitudinal V& flat, and TURCITE B coated with hand scraped, 2 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.
