5.1.17 Aligning Tailstock to Spindle (See Figure 19)
If there is taper appearing on the workpiece while machining by using the tailstock,
the tailstock will need to be realigned to the spindle. Follow these steps:
1. Insert a mandrel between the spindle and tailstock, attach a base of a dial
indicator to the saddle, apply the needle of the indicator to the surface of the
bar, then move the saddle through the longitudinal travel. Take the
measurement of its maximum difference from end to end for later adjustment.
2. Release the 2 bolts labeled “A” in the drawing.
3. Release the screw labeled “B”.
4. Adjust using the 2 opposing screws “C” until the tailstock is aligned with the
spindle.
5. Tighten screw “B” first and then lock “A”.

5.1.18 Spindle Motor Wiring
The SLX 1630 spindle motor is wired for 415 volts in the configuration. The wiring
consists of 3-phase power for the motor and 110 V power for the spindle motor fan.
Please see the diagram found on the motor junction box cover for wiring information.
Each machine does however use a different spindle motor and pulley combination.
Each junction box contains 6 terminals. The terminals should be jumpered together
as shown in the figure. Connect the incoming 3 phase power to the terminals. Make
sure to hook up the wires in the same terminals after the replacement motor is
installed. Failure to do so may run the motor in the wrong direction.
The spindle motor fan wires are also found in the junction box. There is 1 hot wire, 1
neutral wire and 1 ground wire. The hot and neutral wires are connected as shown
for each motor. It does not matter which wires are connected to the hot and neutral
wires. All grounds from each cable are connected to either of the screws labeled
ground.
