For UMC's before 04/2020 the platter will be included in the following kits:

  • 93-1000621: AIR VISE READY FIELD INSTALL UMC500 W/P
  • 93-1000622: AIR VISE READY FIELD INSTALL UMC750 W/P
  • 93-1000623: AIR VISE READY FIELD INSTALL UMC1000 W/P

Installation

1

Assemble the pneumatic manifold as shown:

[1] FITG POLY1/4F NPT1/4M STR BRASS 

[2] FITG PC1/4F NPT1/4M STR BRASS(2x)

[3] FITG ORB6M NPT1/4F STR STL (2x)

[4] O-Ring 2-212 (4x)

Note: Install the four O-rings into alternating grooves on the top face of the manifold block, leaving one empty groove between each installed O-ring.

 

2

Connect the 3 Port Rotary Union Shaft to the 3 Port Rotary Union Shaft Extension using [2] SHCS 1/4-20 X 5/8 make sure the O-Ring 2-011 [1] are seated in the cavities of the shaft.

Torque the bolts to their required specs.

 

3

Press the dowel pin [1] into the anti-rotation block [2] until it bottoms out. 

4

Assemble the platter coupler [1] by installing the three SHCS 5/16-18 X 1/2 [3] and the Vise Ready Seal 57-1057 [2]. these will serve as plugs to the pneumatic lines until the vise is installed. 

Finish assembling the coupler by installing O-Ring 2-031 [4] into the groove of the coupler [5].

 

5

Rotate the B-axis +90 degrees and remove the cover [1]. Return the B-axis to its original position at 0 degrees.

6

Remove the platter by following the removal section of the UMC C-Axis Platter Replacement linked below.

 WARNING: IF YOU DO NOT DEPRESSURIZE THE SYSTEM BEFORE REMOVING THE PLATTER YOU CAN PERMANENTLY DAMAGE THE BRAKE BY REMOVING THE PLATTER.

Note: Take note of the platter orientation before removing to make sure to install the platter in the same orientation later on.

7

Place the platter on a bench and bolt the coupler [1] to the platter using SHCS 1/4-20 X 5/8 [2].

While the platter is on the bench insert the felt strip included in the kit in the groove [3]

NOTE: If the UMC is not exchanging platters reuse the felt strip already in the groove. 

Torque the bolts to their required specs.

8

When using the same platter:

The height measurement between the top of the platter and the top of the coupler needs to be taken to ensure proper fittment of the workholding spud. 

Use a depth micrometer to measure between the two surfaces. The measurement should be 0.7000 ± .0010" for machines built before 5/22/2026 and 0.7560 ± .0010" for machines built after 5/22/2026 [1]. 

Note: The measurement is taken without the seal.

Install shims P/N 59-2350 and 59-2351 as needed to achieve proper workholding height. The shims are installed between the workholding and the platter face [2].

9

Install the coupler onto the shaft assembly [1] by using 1/4-20 X 1 1/4 bolts [3]. Make sure the O-Rings 2-011 [2] are in the cavaties of the shaft and not where the bolts attach.

Torque the bolts to their required specs.

10

Install the coupler and platter assembly [2] back onto the rotary using M12 bolts [1].

Tighten the bolts, but do not torque them down yet.

Follow the installation section of the UMC C-Axis Platter Replacement linked below for the full instruction on how to correctly reinstall the platter.

11

Rotate the B-axis 90 degrees [1].

12

Attach the anti-rotation block [3] to the gearbox using the M6 bolts [4].

If the read head is in configuration [1] you will need to clock it to position [2]  this will require you to redo the compensations on the machine.

If the read head is in configuration [2] the compensations will not need to be redone.

Torque the bolts to their required specs.

Please contact service about borrowing a swivel checker.

13

Install the manifold assembly [2] by inserting the anit-rotation dowel pin [1] into the pneumatic manifold.

AD0543

Revision A - 06/2026

Introduction

This procedure will explain how to install the air vise option on the UMC series machines. 

Please refer to the PNEUMATIC WORKHOLDING procedure to install the air booster, workholding manifold, and the other components that drive the air vise.

Pre-requisites: 

  • Software version 100.20.000.1110

This document applies to the following part numbers:

  • 05-0408 AIR VISE SELF-CENTER 100mm, UMC
  • 05-0409 AIR VISE SELF-CENTER 150mm, UMC

Blank platters have a no drill zone [1] of  Ø7.25 in. and ↧1.75 in. for custom workholding on these platters.  

Machines sold with a blank platter also have the option of purchasing the Haas air vise. 

To install the vise the user will need to drill mounting holes outside the no drill zone [1].  Home the B & C-Axis and drill using the hole pattern that follows:

  • 100mm Air Vise – 4x ½-13 at 220mm [2] x 126mm [3] (on center)
  • 150mm Air Vise – 4x ½-13 at 270mm [2] x 252mm [3] (on center)

Use the brake bleed access hole for reference [4].

NOTE: Pictured is a UMC-500 blank platter but the no drill zone and Haas air vise hole pattern will be the same throughout all UMC models. 

Installation

1

Ensure the system is not pressurized before installing the vise.

Close the air valve [1] at the bottom of the lube cabinet.

Bleed the remaining air out of the manifold by pulling on the air release [2]. Make sure the gauge on the manifold reads zero.

2

Remove the (3x) bolts acting as plugs on the coupler [1]. 

3

Verify that the vise seal [1] is seated properly. The o-ring side of the seal [2] should be facing toward the UMC rotary. 

Note: The seal only sits in one orientation. The location of holes on the coupler are not equally spaced and the seal is made to match the coupler's spacing.

4

Set the C-axis to its home position.

Clean the mating surface inside the center bore and on the spud of the air  vice.

 NOTE: Always clean inside the center bore for chips before installing the pneumatic vise.

Safely lift the vise and match the holes on the coupler to the holes on the vise.

NOTE: The coupler can only be installed to the platter in one orientation and the holes on the coupler are not equally spaced. This means that the air vise can only be installed in one orientation to function correctly.

Secure the air vise to the platter using the 1/2-13 T-nuts and 1/2-13 SHCS provided. 

5

Re-introduce air to the manifold by turning the valve [1].
