UMC Hydraulic Vise - Installation/Removal

AD0514

Revision A - 06/2026

Introduction

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

Please refer to the hydraulic workholding procedure to install the HPU, hydraulic manifold, and the other components that drive the hydraulic vise.

Pre-requisites: 

  • Software version 100.20.000.1110 or higher.

Kits applied:

  • 08-1862 6in HYDRAULIC VISE KIT - UMC
  • 08-1863 8in HYDRAULIC VISE KIT - UMC
  • 08-1864 10in HYDRAULIC VISE KIT - UMC

1

This section is for hydraulic vises with 2 mounting bollts.

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 hydraulic 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:

  • Haas Hydraulic Vise: (2x) 1/2-13 holes at 9 in. (on center) [2]

for the mounting bolts, the mounting bolt. Use the brake bleed access hole for reference [3].

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

This section is for hydraulic vises with 4 mounting bollts.

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 hydraulic 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:

  • 6 & 8 in. Hydraulic Vise  – 4x ½-13 at 103.6mm [2] x 63mm [3] (on center)
  • 10 in. Hydraulic Vise – 4x ½-13 at 124.7mm [2] x 63mm [3] (on center)

For the mounting bolts, the mounting bolt. Use the brake bleed access hole for reference [3].

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

Installation

1

In the position shown the air line is the hole denoted [2] use the brake bleed access port [1] as a reference.

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 hydraulic vice for chips and left over oil. Make sure the screws and washers are removed as well

To install the vise [1] carefully place the vise into the bore, make sure to align the hydraulic holes inside the bore with the hydraulic holes on the vise. 

NOTE: The coupler on the platter can only be installed in one orientation.  The hydraulic holes can only be oriented in one way, be sure to match the holes on the coupler to those on the spud.

Use the SHCS and washer [2] to bolt the vise to the T-nuts in the slot shown in the image. 

 While placing the vise make sure the aligning block are in the center T-slots.  

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

5

To activate the vise, press [CURRENT COMMANDS] and under the workholding tab [1] select workholding type [2] to Custom Hydraulic Vise. 

Adjust Clamp Force

1

Determine the type of Hydraulic Vise is installed on the machine.  LMC or Autogrip.

Use the Hydraulic Vise Clamp Force Chart decal to find the PSI to achive the desired clamp force.

Adjust the Hydraulic Unit pressure valve to the correct PSI.

2

Finally, make sure the vice actuates, to do so press the foot pedal. 

Removing the Vise

1

To physically remove the hydraulic vise press [CURRENT COMMANDS] and disable the vise by going to the workholding tab under the device tab. Change the value of the workholding from Custom Hydraulic Vise to None.

De-pressurize the HPU  by pressing [F3] on the maintenance tab.

Remove the vise and plug the three port holes with the 5/16-18 screws provided in the kit.

Re-activate the HPU by pressing [F4] on the maintenance tab.

2

After the vice is removed plug the hydaulic ports with the 5-/16 screws and washers.

 NOTE: Make sure there are O-rings in the grooves before plugging with the screws.
