Rotary - TR/TRT/T5C - Removal - 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).
Safety Notes
Caution: When you do maintenance or repair on CNC machines and their components, you must always follow basic safety precautions. This decreases the risk of injury and mechanical damage.

Do these steps before you do work in the machine or in the control cabinet:
  • Set the main circuit breaker to the OFF position.
  • Use an approved lock with an approved safety tag. Always follow lock-out procedures in accordance to local government rules.
  • After turning off the machine, wait at least 5 minutes before working in the control cabinet, to allow power to dissipate. Wait for the voltage indicator LED on the vector drive to go off completely.
  • Always turn off the main air supply when you work on any part of the pneumatic system.
  • Make sure to rest the spindle head on a block of wood when work is done on a vertical axis. This will prevent any unintended movement that could result in the axis falling.
  • Never alter any safety circuits on the machine.
You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes. Serious damage to the machine components can result in costly repairs. The service technicians at your Haas Factory Outlet (HFO) have the training and experience, and are certified to do these tasks safely and correctly. The repair and service work performed by your HFO is protected with a limited warranty.
danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not fully understand. If you have any doubts about doing a procedure contact your Haas Factory Outlet (HFO) and schedule a service visit.

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

Do this procedure for machines:
  • All VMCs
  • For a TRT100, the machine must have software version M18.24A or higher.

Tools Required

Lifting Chain [1]
Spreader Beam [2]
Lifting Device [3]

Rotary - TR/TRT/T5C - Removal

Step 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.

Step 2

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.

Step 3

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.

Step 4

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.

Step 5

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.

Rotary - TR/TRT/T5C - Lifting Instructions

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:

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
