[2]  FITG ORB6M JIC6M STR STL (2x)

[3] 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 staff to the staff extension using [2] SHCS 1/4-20 X 5/8 make sure the O-Ring 2-011 [1] are seated in the cavaties 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.

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 fitment 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.

UMC Hydraulic Vise - Troubleshooting Guide

TG0089

Introduction

The UMC series machines have two types of workholding and vises: hydraulic [1] and pneumatic [2]. This troubleshooting guide will have information in regards to the hydraulic workholding [1]. 

For further information on how to install the hydraulic or pneumatic workholding mechanisms/vises please refer to the links below:

Hydraulic Workholding Links: 

Symptom Table

Symptom Probable Casue Corrective Action
Hydraulic fluid is coming out of the air blast port. Verify orientation of the ports between the coupler and the spud of the vise. The open and close ports may be lined up with the air blast port.  Remove the vise from the platter and verify if the orientation is correct. Newer versions of the coupler will have the air port labeled "AIR" 
Vise jaws are not closing when commanded and HPU is functioning properly.
Hydraulic lines are clogged.  Debris may have been introduced when installing or removing the hydraulic vise from the machine. 

If the system has a the hydaulic filter fitting on the side attached to the HPU, check the filter fittings to see if any debris is present. 

If debris is present clean the fitting off, replace the hydruaulic oil and continuously check the fitting so it does not get clogged. Replace the fittings as needed
Clamp and unclamp solenoids have failed due to debris present in the hydraulic oil.

If the system does not have the hydraulic filter fitting on the side attached to the HPU, update the system by ordering two 58-2127 FILTER 65 MICRON HYD 6ORBM 6JICM STR STL and replace the two 58-0038 FITG ORB6M JIC6M STR STL that were already installed on the hose. 

Replace the hydraulic oil and continuously check the fitting so it does not get clogged. Replace the fittings as needed

Hydraulic Vise - HPU Dial and Valve

1

Pressure drop on the controller gauge page is normal as it is monitoring the accumalator pressure [1]. Pressure on the controller should always be higher than on the dial for the system to keep clamping force consistent.

 NOTE: 100 psi/5 minutes is what is considered normal pressure drop.

2

The HPU dial [1] located on the HPU will display the pressure applied to the vise, the controller HPU pressure found on the gauge page will display the pressure monitored from the accumulator [2].

 NOTE: The pressure may vary within 10 psi as long as the accumulator is funtioning properly. 

3

To make adjustments to the pressure applied to the vise, the knob denoted as [1] is used to make the adjustment while knob denoted as [2] is used to lock the adjustment in place.

NOTE: If the pressure value is drifting more than 10 psi on the dial check if knob [2] is locked in place and check for any leaks from the vise or the system. 

 

4

Haas hydraulic vises will have a hydraulic vise clamp force chart that can be used to achieve the correct clamp force in relation to the pressure on the dial. 

NOTE: This chart will NOT apply to third party vises.
