Change Gears
Lubricate the change gears with thick machine oil or grease once a month.
5.5
Other parts
There are other lubricating points on the input shaft bracket of the gearbox, the
handwheel on the apron, the longitudinal and cross slide, the thread dial indicator, the
tailstock and the bracket. Use a grease gun to put a few drops of oil onto the
lubricating positions from time to time. Lubricate the apron worm and worm gear, half
nut and leadscrew twice a month. Apply a light film of oil to the bed way and all the
other bright parts like the tailstock quill, feed rod etc. once a day.
6. Test Running
6.1 Spindle Speed Control
A. Identification before operation
Ensure that lubrication has been carried out as described before.
When the main spindle is rotating, the gearbox and the feed axis of the bed sides are
put into operation. The forward/reverse switch (4) should be in the neutral position.
The feed axis selector (6) and feed/thread selector handle (6) are in the disengaged
position. Under these circumstances, both the longitudinal travel handwheel (21) and
the cross travel handle (25) can be operated by hand.
B. Main spindle rotation
The main spindle rotation is selected by the forward/reverse switch.
C. Main spindle speed
The speed of the main spindle is selected by the high/low speed selector (1). For both
the high and low speeds, there are two different positions. For the correct speed, refer
to the speed chart. Never change the speed before the motor has stopped completely!
Adjustment of the speed can be assisted by turning the main spindle by hand.
D. Running In
Running in should be done at the lowest possible speed. Let the machine run at the
lowest speed for approximately 20 minutes, then check for any irregularities. If
everything seems in order, gradually increase the speed.
E. Operation
Only use high peripheral speed type chucks.
The maximum spindle speed for chuck plates with a 250mm should not be more than
1255rpm. When thread cutting or auto feeding are not in use, the feed/thread selector
should be in the neutral position so to ensure the disengagement of the leadscrew and
the feed rod. To avoid any unnecessary wear, the thread dial indicator should be out
of mesh with the leadscrew.
