Autolube System
The Autolube system automatically lubricates the slideways, guideways, and ballscrews.
The preset discharge rate is 3.0 cubic centimeters (cc) per pump cycle. Refer to Adjust
Autolube Discharge Rate, on page 3 - 7 for details. The way lube pressure should be set
at 2.9 bar or 42 psi.
Machining centers use a digital timer Autolube system. When servos are On and
adequate pressure is attained, the system cycles on for 30 seconds to send lube oil
through the machine, then cycles off for 15 minutes. The Autolube system is located on
the back of the machine. Open the machine’s rear access door to access the Autolube
system.
