Rotary - Removal - TR - TRT - T5C - AD0247

Introduction

This procedure tells you how to remove a TR, TRT, or T5C rotary from a Haas VMC. For these instructions, the trunnion axis is the A Axis (TILT). The platter axis is the B Axis (ROTARY).

Prerequisites:

Refer to the Tools Required section for images of these tools:

To find the weight of your rotary go to www.haascnc.com. Use the Search function to find the rotary model. Select the rotary model from the list results. Find the weight in the "Specifications" section.

  • Lifting Chain or Strap [1] - The chain or strap must be rated for the weight of the rotary.
  • Spreader Beam [2] - A spreader beam is recommended to keep the lifting chains vertical. It must be rated to the weight for the rotary. The width of the spreader beam must be the same as the width between the lifting eye bolts.
  • Lifting Device [3] - A lifting device, such as a forklift, lifting hoist, etc, must be rated for the weight of the rotary.
Machine Compatibility:
  • All VMCs
  • For a TRT100, the machine must have software version M18.24A or higher.
Tools Required:
  1. Lifting Chain
  2. Spreader Beam
  3. Lifting Device

Rotary - TR/TRT/T5C - Lifting Instruction

Lift the rotary table with the lift rings as shown to prevent damage to the gear set. Attach an air supply to the rotary before you lift it. All rotary tables (HRT's, TR's TRT's and T5C's) use the 1/2-13 eyebolts. Haas Automation, Inc. does not supply lifting chains or straps for rotary products.

If spreader bars are not available, eyebolts may be used as shown:

TR500SS

To lift the TR500SS have your lifting mechanism right above the center of gravity, position [1], to ensure the rotary is lifted uniformly.

Lift the machine from the eye bolts near the A frame [2] and the lifting bracket [4]. 

NOTE: Make sure to use straps [3] or something that wont damage the platter as lifting it from this location will interfere with the platter.

 

Rotary - TR/TRT/T5C - Removal

1

Center the table and jog it to the front of the machine near the door. Turn ("tilt") A axis 90 degrees to access the T-Nuts.

Press [EMERGENCY STOP].

Loosen the T-Nuts. Remove only the inner T-Nuts [4], the 1/2-13 double-threaded studs [3], washers [2], and nuts [1].

 Note: You need the outer T-Nuts [4], the 1/2-13 double-threaded studs [3], washers [2], and nuts [1] to keep the rotary stable until you remove it.

Home the A axis.

 Note: The A Axis must be in the home position to be moved. This will prevent damage to the rotary.

Rotary - Disable

This procedure tells you how to disable a rotary axis. When you disable a rotary axis, you can prevent it from moving but keep it configured.

1

A rotary axis is enabled when it has a mark [3] to the left of the rotary axis. The rotary axis shows in the Position [4] screen when it is enabled.

Select the rotary axis [1] to disable.

Push [ENTER].

The mark for the rotary axis goes away [5].

The axis goes away from the Position screen [6].

Do this step again for the other rotary axis [2] if necessary.

Rotary - Clear

This procedure tells you how to clear a rotary axis configuration from the Current Rotary Selection. Do this procedure when you remove a rotary unit from the machine and you must install a different rotary unit.

1

Push [EMERGENCY STOP].

Push [ORIGIN] to clear the rotaries.

The Clear Rotary Configuration [1] display shows.

Push [ENTER] [2].

Power cycle the machine.

The rotary configurations are cleared from the rotary selection.

Disable Rotary Axes - CHC

1

Release [EMERGENCY STOP].

Change Setting 30 4TH AXIS ENABLE to OFF. Push [ENTER].

Save the file with a unique file name. Use less than (12) characters. Push [ENTER].

Change Setting 78 5TH AXIS ENABLE to OFF. Push [ENTER].

Save the file with a unique file name. Use less than (12) characters. Push [ENTER].

Push [POWER OFF].

Set the main circuit breaker to the OFF position.

Lock the main circuit breaker. Use an approved lock with an approved safety tag.

Disconnect all of the rotary cables from the control. Make sure the rotary air hose is connected to an air supply. The air pressure engages the brake on each rotary axis.

Rotary Blocking

1

Install the standoffs, and shipping brackets on:

  • The right rear [1] of a TR160/210.
  • The top [2] of a TR160Y.
  • The rear center [3] of a TRT100.

 Note: The TRT160, TRT210, and T5C do not have shipping brackets.

For a TR310, install the (2) T-nuts on the rotary platter. Install the (4) 1/2-13 screws and washers [5] and [6] to the shipping bracket [4].

Remove the cable from the clamp, the clamp and cut the zip ties. Coil the cables on the rotary.

Remove the T-Nuts, the 1/2-13 double-threaded studs, washers, and nuts.

 Note: You may not be able to remove all of the T-Nuts until you lift the rotary.

2

Install the lifting chains [1] and the spreader beam [2].

 Caution:

  • Use a spreader beam, chains, and the air hose connected to an air supply to prevent damage to the rotary.
  • Use a spreader beam to make sure the chains stay vertical.
  • Make sure the A Axis is in the home position to prevent damage to the rotary.

Refer to the "Rotary - TR/TRT/T5C – Lifting Instructions" at the end of the procedure for more information.

3

Remove the rotary from the machine. If necessary remove the locating pins and the alignment keys [1] from the rotary.

Slide the T-Nuts off the table.

Disconnect the air hose from the air supply. This disengages the brakes on both of the rotary's axes.

Coil the tube and set it on the rotary.

Set the main circuit breaker to the ON position.

Release [EMERGENCY STOP].

Push [POWER ON]. No alarms will occur if the rotary removal is done correctly.
