Try to move the aluminum block. If the drawbar height is correct, the block does not at 0.100".

Jog the Z Axis 0.110" above the block.

Push and hold the tool-release button.

Try to move the aluminum block. If the drawbar height is correct, the block should be loose at 0.110".

Important: New tolerance for Single Sensor TRP VF-1 trhough VF-5 machines. No need to make adustments to the drawbar height if tight between 0.080" to 0.130". 

Note: The number of jog increments in the negative direction is the number of shims to add. The number of jog increments in the positive direction is the number of shims to remove.

VMC - Belt/Gearbox Drive - TRP - Add or Remove Shims

1

 

Note: For TSC g to step 2.

Disconnect the proximity-swich and solenoid cables at the solenoid bracket. Disconnect the pre-charge and tool-release air tubes from the solenoid. Lift the TRP assembly from the spindle an dmove it foreword to remove it. Use an open-ended wrench to hold the TRP shaft. Use a closed-end wrench to turn the TRP bolt [1] clockwise to loosen.

Note: The threads for the tool-release bolt in the opposite direction.

Add or remove shim washers [2] from the tool TRP bolt. Apply medium-strength thread-locking compound (for example, blue Loctite®) to the TRP bolt. Install the TRP and do the "TRP Push Out - Check" steps again.

Disconnect the proximity-switch and solenoid cables at the solenoid bracket. Disconnect the TSC hose. Disconnect the pre-charge and tool-release air tubes from the solenoid. Lift the TRP assembly from the spindle and move it forward to remove it. Remove the TSC seal housing [1] and the TSC seal [2]. If the seal housing has hoses attached to it, remove them. Use an open-ended wrench [3] to hold the TRP shaft. Use a closed-end wrench [4] to turn the TRP bolt [5] clockwise to loosen.

 Note: The threads for the tool-release bolt go in the opposite direction.

Add or remove shim washers [6] from the tool TRP bolt. Apply medium-strength thread-locking compound (for example, blue Loctite®) to the TRP bolt.

Install the TSC seal and TSC seal housing. If you removed hoses from the housing, connect them. Do the "TRP Push Out - Check" steps again.

VMC - TRP - Pre-charge - Adjustment

Caution: Do not do this procedure on a machine that has through-spindle coolant (TSC). Thisdamages the TSC system.

1

Find the knob on the pre-charge air regulator. Turn th eknob counter clockwise until it stops.

Make sure Parameter 149 PRE-CHARGE DELAY is set to 300.

Make sure no tool is in the spindle.

Push the [Tool Release] button.

Note: If th epre-charge is not correctly adjusted, you hear a loud noise when the piston hits the drawbar.

Turn the main air pressure regulator clockwise one half turn.

Push the [Tool Release] button.

If you hear the TRP hit the drawbar, turn the main air pressure regulator clockwise one quarter turn.

Caution: Do not increase the pressure too much. Only increase the pressure until you cannot hear the TRP hit the drawbar.

VMC - TRP - TSC - Pre-charge - Adjustment

This procedure tells you how to do these tasks:

  • Assemble the pressure gauge service kit.
  • Use the pressure kit to adjust the TRP pre-charge.

 Note: Do not do this procedure if the machine does not have through-spindle coolant. The location of the pre-charge solenoid may vary.

1

Do these steps to make a pressure-gauge assembly:

  • Attach the gauge [1] to the tee-fitting [3].
  • Attach the (2) quick-release fittings [2] to the tee-fitting.
  • Put the 1/4" tubing [4] into one of the quick-release fittings [2].

2

Disconnect the tube [1] from the output-side of the pre-charge pressure regulator [4].

Put the tube into the top of the pressure-gauge assembly [2].

Connect the 1/4" tube [3] from the pressure-gauge assembly to the regulator.

3

On some machines, you cannot adjust the regulator. Use the pressure-gauge assembly to make sure the regulator operates correctly. Do these steps to make sure the regulator [2] operates correctly:

Adjustable regulator:

Push and hold the button on the pre-charge solenoid valve [1]. Do this for 20 seconds.

Pull the regulator adjustment knob to unlock it. Set the air pressure to Belt/Gearbox: 4 psi (0.28 bar) Inline: 30 psi (2.1 bar). Release the solenoid button. Push and hold the button on the solenoid valve [1], again. Do this for 20 seconds.

Make sure the gauge shows Belt/Gearbox: 4 psi (0.28 bar) Inline: 30 psi (2.1 bar). Release the solenoid button. Push the regulator adjustment knob to lock it.

Non-adjustable regulator:

Push and hold the button on the pre-charge solenoid valve [1]. Do this for 20 seconds.

Make sure the gauge shows Belt/Gearbox: 4 psi (0.28 bar) Inline: 30 psi (2.1 bar). If the gauge does not shows the correct pressure, the regulator is defective. Replace the regulator.

Both: Remove the pressure-gauge assembly from the regulator.

VMC - TRP 2 Sensor - Adjustment

Prerequisites:

  1. Set Parameter 76 LOW AIR PRESSURE to 99999
  2. Turn the main air regulator to decrease the air pressure to 75 psi (5.2 bar).

 

1

Adjust the Draw Bar Closed sensor as follows:

Put a piece of paper on the table to prevent damage to the table.

Put the aluminum block [2] on the piece of paper.

Slowly jog the Z Axis until the toolholder lightly touches the block.

Push [POSITION] [ORIGIN] to zero out the Z Axis.

Push [ .001/1 ].

Jog the Z Axis 0.060" (1.52 mm) above the block.

2

Go to the I/O Diagnostics page.

Push and hold the [Tool Release] while you monitor the status of Draw Bar Open.

Adjust the unclamp sensor until Draw Bar Open changes to 1 when you push the tool-release button.

Jog the Z Axis 0.050" (1.52 mm) above the block.

Push and hold the [Tool Release] while you monitor the status of Draw Bar Open.

Adjust the lower (unclamp) sensor until Draw Bar Open changes to 0 when you push the tool-release button.

3

The adjustment of the lower unclamp sensor is complete when:

  • At 0.060" (1.52 mm) above the block, (Draw Bar Open=1) . The sensor is on.
  • At 0.050" (1.27 mm) above the block, (Draw Bar Open=0) . The sensor is off.

4

Adjust the Draw Bar Cloased sensor as follows:

Remove the toolholder from the spindle.

Go to [MDI/DNC] and delete everything.

Write M59 P1120.

Put a 0.020" (0.508 mm) feeler gaugue (or shim stock) [1] between the tool-release bolt [2] for the TRP and the drawbar [3].

Push [Cycle start] to activate the unclamp pre-charge solenoid.

5

Monitor the status of Draw Bar Closed. Adjust the clamp sensor until the Draw Bar Closed = 0 when the unclamp pre-charge solenoid is activated.

6

Push [Reset]

Put a 0.020" (0.508 mm) and a 0.040" (1.016) mm feeler gauge (or shim stock) [1] between the tool-release bolt [2] for the TRP and the drawbar [3].

Push [Cycle start] to activate the unclamp solenoid.

Make sure Draw Bar Closed = 1 when the unclamp pre-charge solenoid is activated if not readjust if necessary.

7

Set Parameter 76, LOW AIR DELAY, to 1500.

Do some tool changes to make sure that the TRP is correctly adjusted. Make sure the TRP has no leaks.
