Through Spindle Coolant - Installation

1

Route the clear 5/32 TSC positive pressure pneumatic hose [1] from the CALM cabinet though the cable channels to the top of the motor.

Route the purple TSC air purge pneumatic hose [2] from the CALM cabinet though the cable channels to the top of the motor.

Route the purple TSC auto clean cylinder pneumatic hose [4] from the CALM cabinet though the cable channels to the TSC pump.

Route the TSC coolant hose [A] from the TSC pump though the cable channels to the top of the motor.

Plug the TSC pressure senor cable [B] into the plug on the wire harness labeled "TSC PRESSURE" [3].

2

Install the TSC check valve assembly bracket [1] to the enclosure panel at the back of the column using the (2) 1/4-20 sheet metal screws [2].

Install the TSC check valve assembly [3] onto the bracket [1] using the (2) bolts [4].

3

Install the TSC pressure sensor cable [1] onto the plug at the top of the TSC check valve assembly.

Install the coolant hose from the TSC pump [2] onto the fitting at the top of the TSC check valve assembly.

Install the straight end of the short TSC hose [3] onto the fitting at the bottom of the TSC check valve assembly.

Install the black pneumatic hose [4] onto the push-to-connect fitting marked by the black zip tie.

Install the purple pneumatic hose [5] onto the push-to-connect fitting marked by the purple purple tie.

4

Remove the push-to-connect fitting [1] from the 90 degree fitting [4].

Install the check valve [2] and nipple [3].

Reinstall the push-to-connect fitting [1].

Install the black pneumatic hose [5] from the TSC check valve assembly onto the push-to-connect fitting.

Remove the spindle air purge assembly from the top of the motor.

5

To install the replacement shaft [2]:

  • Be sure the threads and o-ring on the shaft [2] are clean.
  • Apply Red-I grease [1] to the o-ring of the shaft [2].
  • Turn the shaft [2] counterclockwise to install it onto the spindle motor.
  • Torque the shaft [2] to 30 ft-lb (41 Nm).
  • Remove the spindle lock tool.
  • Use the dial indicator [3] to measure the total indicated runout (TIR) of the shaft [2] and the top carbide [4].

The radial [3] and axial [4] TIR must be less than .0005''.  If the TIR exceeds this value, shim the TSC shaft.

6

To shim the TSC shaft:

Measure the radial runout [1].

Mark the high spot with a pen [2].

Loosen the TSC shaft enough to create a gap between the TSC shaft and the motor shaft.

If the radial runout is than .0015'' use .0005'' shim stock.

If the radial runout is greater than .0015'' use .001'' shim stock.

Insert the shim at the marked location [3] and torque the TSC shaft to 30 ft-lb.

Trim away the excess shim stock.

After shimming the TSC shaft:

Measure radial runout [1].  It must not exceed .0005''.

Measure axial runout [2].  It must not exceed .0005''.

If shaft runout cannot be corrected with shims contact Haas service.

7

Install the compensating union [1] using the standoffs [2], washers [3] and bolts [4]

8

Make sure the compensating union with the mounting bolts [1] are loose and insert the aligment tool [2] through the fitting on the top of the coolant union to align it with the motor shaft.

Turn the motor by hand to make sure the shaft is not rubbing as you tighten the union bolts. Torque the bolts to 12 ft-lbs (16 Nm)

Remove the alignment tool.

Run the spindle motor at 100 RPM and verify the union is not rubbing on the shaft.

9

Insert a screw driver [1] into the top JIC fitting [2] until you feel it contact the piston [3].

 Note: The top cover has been removed in this image to illustrate the piston. Do not disassemble the union.

Lightly press downwards until you feel the piston [3] contact the shaft [4] to eliminate the gap [5]. The piston will move about 0.040".

Install the replacement TSC hose from the check valve to the union. Install the new 5/32 clear hose from the spindle solenoid to the union. Connect the drain hose to the union.

10

Install the 90 degree fitting end of the short coolant hose [1] onto the top of the union.

Install the 5/32 clear hose [2] onto the push-to-connect fitting on the union.

Install the drain hose [3] onto the union drain port and route it to the hole in the spindle head casting.

11

Install the push-to-connect fitting [1] the adapter [2] and the T-fitting [3] onto the spindle air solenoid.

Install the 5/32 clear pneumatic hose [7] into the push-to-connect fitting [1].

Install the TSC purge solenoid [4].

Install the purple pneumatic hose from the TSC check valve [6] onto the push-to-connect fitting on the TSC purge solenoid with the check valve.

Install the purple pneumatic hose from the TSC auto clean cylinder [5] onto the push-to-connect fitting on the TSC purge solenoid without the check valve.

12

Remove the cover [1] for the power supply (PSUP) PCB.

Remove the push-on covers [2] for the connectors from position CB4.

Remove the electrical jumper at position JP2 [3] on the PSUP PCB.

Install the 15A circuit breaker [4] at position CB4.
