Coolant

Machine coolant must be water-soluble, synthetic-oil based, or synthetic based coolant/lubricant.

  • Do not use mineral cutting oils; they damage rubber components and void the warranty. 
  • Do not use pure water as a coolant; components will rust. 
  • Do not use flammable liquids as coolant. 
  • Do not submerge the unit in coolant. Keep the coolant lines on the workpiece spraying away from the rotary unit. Tool spraying and spatter are acceptable. Some mills provide flood coolant such that the rotary unit is practically submerged. Try to cut down the flow to match the job. 

Inspect the cables and gaskets for cuts or swelling. Have damaged components repaired immediately.

HRT / TRT Inspection

Warning: The Rotary Servo Control box will not work properly without the batteries.  These batteries are used by the control to retain the rotary servo control configuration parameters and programs.

Parts Required:

  • Lithium Battery (Qty: 2) (see note for sourcing instructions)

NOTE: To determine which battery to source please refer to our Lithium Battery Reference Guide

Battery Installation

Remove the SHCS using a 7/64 allen key that hold the cover of the rotary box.

Note: Be careful with the rotary box fan cable and external battery cable.

 

Remove the clips on the external battery board [1].

Install the batteries and place the clips back around the batteries as they were found originally.

  • The external battery board is mounted on the side of the cover using Velcro and can be removed from the Velcro to make installing the batteries easier.  
  • Reinstall the cover and verify the rotary control box functions properly

Refer to the How to Initialize Servo Control to Factory Default Parameters procedure.

6.6 Rotary - Backlash Testing

Rotary - Backlash Testing

Revision A - 4/2025

Introduction

The document below provides a detailed explanation for finding backlash on a Haas Rotary unit.

Note: The following rotary units can not be checked for backlash HRT110, HRT210SHS, HRT160SS /210SS.

 

 

Backlash Test for HRT and HRC

Note: HRC units must be plugged, powered up, and disconnected from the air when checking backlash. 

Disconnect the air supply to the rotary.

Put the dial indicator on the rotary as shown in the illustration.

Use an aluminum pry bar (approx. 1" X 1/2" X 18") to push down the spindle [1] at about 15 ft-lb (20 N-m), and then release. Set the indicator dial to 0.

Use the pry bar to push up the spindle [2] at about 15 ft-lb (20 N-m), and then release.

If the indicator shows more than 0.0005" (0.01 mm), the adjustment of the spindle backlash is necessary.

For this adjustment you must send the rotary to a certified rotary repair facility.

For instructions on where to find a rotary repair facility and how to send your rotary unit, go to  www.haascnc.com.

 

Backlash Test for Trunnions

A / B Axis

Place a flat rectangular magnet on the flat part of the TR as shown in the picture. The flat side that will be used to measure backlash should be pointed to the center of rotation of the axis. 

Set the tip of the dial indicator on the flat surface of the magnet as shown in the picture. Pull the bar three times to get the gear teeth fully engaged in one direction and set the dial gage to zero. 

Push the bar in the opposite direction once and read the dial gage. It will show the amount of backlash. 

C Axis

Disconnect the air supply to the rotary.

Put the dial indicator on the rotary as shown in the illustration.

Use an aluminum pry bar (approx. 1" X 1/2" X 18") to push down the spindle [2] at about 15 ft-lb (20 N-m), and then release. Set the indicator dial to 0.

Use the pry bar to push up the spindle [2] at about 15 ft-lb (20 N-m), and then release.

If the indicator [1] shows more than 0.0005" (0.01 mm), the adjustment of the spindle backlash is necessary.

For this adjustment you must send the rotary to a certified rotary repair facility.

For instructions on where to find a rotary repair facility and how to send your rotary unit, go to  www.haascnc.com.

Backlash Test for TRT

A Axis

Place a magnetic block on the front of the TRT platter as shown in the following image. 

Place the dial gauge tip on side of the block's machined surface. [1]

Note: Measure how far the tip of the indicator is to the  A -Axis of rotation [2].

Zero the indicator, then move the A axis towards the indicator (.001). This will allow enough rotation to engage the gears in one full direction. 

Important: Write down the initial measurement found of the dial indicator as this value will be used later. 

Select the smallest increment (.0001) and move away from the indicator 10 times.

Note: Backlash value will be the difference from the starting measurement subtracted by the final position found on the dial indicator. 

B Axis

Place a magnetic block on the front of the TRT platter as shown in the following image. 

Place the dial gauge tip on side of the block's machined surface. [1]

Note: Measure how far the tip of the indicator is to the  B -Axis of rotation [2].

Zero the indicator, then move the B - Axis towards the indicator (.001). This will allow enough rotation to engage the gears in one full direction. 

Important: Write down the initial measurement found of the dial indicator as this value will be used later. 

Select the smallest increment (.0001) and move away from the indicator 10 times.

Note: Backlash value will be the difference from the starting measurement subtracted by the final position found on the dial indicator. 

Calculating Arc Seconds

The backlash tolerance on rotaries is given in arc seconds. The equation to calculate arc seconds is a=(1,296,000*b)/(2*pi*r). Where; a=arcseconds, b=backlash, r=radius of measured arc and pi=3.14. 

The total backlash tolerance is plus or minus 30 arc-seconds. 

   Base to A axis [2] Rim to B Axis [1]
TRT100 .88 from platter 2.0 in (50 mm)
TRT160 1.66 3.2 in (80 mm)
TRT210 1.4 4.6 in (115 mm)
TRT310 1.93 in 6.1 in (155 mm)

Note: The TRT 100 can be back driven so it needs to be plugged into power and disconnected to air.
