INTRODUCTION

Compared with the traditional standard manual machine, the Centerless Grinder PC-18S-NC adopts a servo motor to drive the regulating wheel and the lower slide feed. With a conversational screen, let users have more convenient operability.

Using the PC-18S-NC Centerless Grinder, the operator can choose the most suitable grinding method and parameters according to the workpiece requirements, such as through-feed grinding or in-feed grinding, to process various workpieces.

Palmary continue to innovate in Centerless Grinding Technology. PC-18S-NC Centerless Grinder, as part of its product line, demonstrates advanced grinding capabilities and operability and meets the needs of high-accuracy grinding.

 
FEATURES
centless-grinder-spindlejpg

Precision spindles

The GW spindle and the RW spindle are precision machined and made from alley steel, processed with normalization, aging, and heat treatment, then proceed to sub-zero treatment, finally finished after precision machining and grinding.

Pressure switch

When starting the GW and RW spindle, this pressure switch allows starting only when oil enters into bearings thereby providing safety protection for the spindle bearings.

Feed screw

The feed screw is manufactured from alloy steel. It's also normailzed, high frequency harden and precision ground in order to have high feeding accuracy and excellent wear resistance.
