INTRODUCTION
Centerless Grinders Economic Servo Type PC-12S Series is a high-quality grinder manufactured by Palmary. Different from traditional standard models, this series of grinders adopt servo motor to drive the regulating wheel speed. This improves the operation of the regulating wheel more precise and easier to operate.
As a grinding machines manufacturer, Palmary have always been committed to providing high-quality grinding machines and professional technical support. The operation of a Centerless Grinder is a complex process requiring technical knowledge and experience. However, Palmary provide users with a user-friendly operation interface and comprehensive technical guidance, enabling the operator to give full play to the capabilities of the grinding machine and achieve high-efficiency and high-accuracy grinding.
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.
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.
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.
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.
