INTRODUCTION
If you are serious about grinding accuracy and efficiency, the centerless grinders from PALMARY will meet your stringent challenges. The NC-controlled model is quality constructed throughout for delivering the operational performance that you expect.
The machine structure is manufactured from high-quality Meehanite cast iron, heat treated and stress relieved before machining, to make sure the high rigidity.
FEATURES
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.
Lubrication system
The automatic lubricator provides lubrication to the GW spindle. Also all slideways are lubricated by a centerlized lubrication system, ensuring proper lubrication and feeding accuracy.
