2.16 Lubrication
The TRAK Lathe auto lube system provides centralized automatic lubrication for the carriage, cross slide and
ballscrews. The lube pump has a 2-liter reservoir filled with Mobil Vactra Oil No. 2 (ISO30).
The lube pump has electronic memory which acts as an internal clock to keep track of the running time of
the axis motor. Even when the spindle is turned off, the lube pumps internal clock will not reset. The
interval between pump cycles is based on axis motor movement time.
2.16.1
Lube Pump Operation
The pumping output can be regulated electronically to control the Interval Time between pumping
cycles, and the Discharge Time of each pumping cycle. The pump can also be run manually through
a key found under service codes. The following describes the steps used to program the lube pumps
Interval and Discharge times.
Start with using Service Code “E”.
Setting Interval Time:
Service Code 301
Press "Mode", "Set up", "Service Codes", "C" (Machine Setup), Code 301, and then enter the
desired Interval time in minutes.
Setting Discharge Time:
Service Code 302
Press "Mode", "Set up", "Service Codes", "C" (Machine Setup), Code 302, and then enter the
desired Discharge time in seconds.
To manually Pump Oil:
Service Code 300
Press "Mode", "Set up", "Service Codes", press "E", and then press Code 300 (Lubrication Pump
Switch). The pump will pump oil for the amount of time programmed in Code 302. The spindle does
not need to be turned on.
2.16.2
Factory Default Values
Interval Time - 60 min
Discharge Time - 15 sec
Discharge Pressure - Approximately 100 - 150psi
To adjust the amount of Discharge Pressure displayed on the lube pump gauge, loosen the jam nut
and turn the adjustment screw located on the top right side of the lube pump while the lube pump
is activated. To activate the lube pump use Service Code 300.
CAUTION!
Failure to properly lubricate the lathe will result in the premature failure of ball screws
and sliding surfaces.
CAUTION!
Failure to manually activate the pump at the beginning of each day, or allowing the Auto
Lube to run dry may cause severe damage to the lathe way surfaces and ballscrews.
CAUTION!
Oil that is too heavy and viscous such as 50W or 90W oil can clog oil line tubing. Do not
mix detergent type automotive or multi-purpose oils with the Mobil Vactra Oil No.2 used
in this application.
