2.13.2 Automatic Way Lubrication Pump
The 1630 auto lube system provides centralized automatic lubrication for the
carriage, cross slide and ballscrews. The lube pump has a 2-liter reservoir filled with
S.A.E. 30-weight oil.
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 S.A.E. No. 30 lubricating oil used in this application.
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 axis motors are turned off, the
lube pumps internal clock will not reset. The interval between pump cycles is based
on axis motor movement time. Also, every time the control is first turned on, the
lube pump will run for 1 lube cycle as soon as the axis motors are commanded to
run.
2.13.3 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.
Setting Interval Time: Service Code 301
Press "Mode", "Set up", "Service Codes", "E" (Lube Pump Setup), Code 301, and
then enter the desired Interval time in minutes.
Setting Discharge Time: Service Code 302
Press "Mode", "Set up", "Service Codes", "E" (Lube Pump 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.
2.13.4 Factory Default Values
Interval Time - 20 min
Discharge Time - 15 sec
Discharge Pressure - Approximately 690 – 1034 kPa (100-150 PSI)
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.

3.1.5 Threading Problems
Threads can be cut with an unlimited number of pitches and up to 10 leads.
To reduce the relief area when threading up to a shoulder the spindle speed should be
reduced as much as possible. The slower the speed of the spindle, the closer the cutting
tool can come to the end of the programmed thread before it pulls out and retracts. If a
nut must be turned all the way up to a shoulder, machine a relief area behind the last
thread.
NOTE: No machine can thread up to a shoulder and instantaneously pull out.
