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, featuring low rotational speed and high torque. This improves the operation of the regulating wheel more precise and easier to operate. Its economical mechanical structure makes it an affordable choice for machining.
Precision Spindles
Feed Screw
The feed screw is manufactured from alloy steel. It's also normalized, 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 centralized lubrication system, ensuring proper lubrication and feeding accuracy.
