Mini Mill, Super Mini Mill - P-Cool - Installation - Introduction

Do this procedure for a Mini Mill or Super Mini Mill. This procedure tells you how to install a programmable coolant (P-Cool) system.
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.

Machine Compatibility

Mini Mills (MM) and Super Mini Mills (SMM) built in 2015 and after have these features:
  • cable 200 is installed at the factory. You do not need to install the cable from the kit.
  • a flood coolant ring is installed at the factory. You do not need the modular-hose (Loc-Line) nozzle in the kit.

On Mini Mills and Super Mini Mills built before 2015 you must install these items from the kit:

  • cable 200
  • the modular-hose (Loc-Line) nozzle assembly

Parts Included

KIT PN: 30-9468, INSTALLATION KIT, P-COOLMM. QTY: 1
30-11251a
QTY: 1
PCOOL ASSY, M12, SHORT NOZZLE

Tools Required

Power Drill
3/8" (10 mm) bit
Hacksaw
Metal file

Templates

Some spindle head covers do not have the necessary slot to install the cable. For these machines, use this template.

Remove the spindle head cover.

On the side of the head cover, measure the dimensions [A] from the bottom edge of the cover and [B] from the back edge of the cover.

  • A - 1.25" (32 mm)
  • B - 3.63" (92 mm)

Put a mark [1] at the intersection of [A] and [B].

Drill a Ø0.375" (10 mm) hole at the mark [1].

Use the hacksaw to make (2) cuts [2] between the bottom edge of the spindle head cover and the hole to create the slot.

Use a file to make the edges of the slot smooth.

Mini Mill, Super Mini Mill - P-Cool - Modular-Hose Nozzle - Installation

Do this procedure on a Mini Mill or Super Mini Mill that was made before 2015. These machines have a modular hose (Loc-Line). This procedure tells you how to install a programmable coolant (P-Cool) system.

Step 1

Set the main circuit breaker to the OFF position.
Push POWER OFF.

Lock the main circuit breaker. Use an approved lock with an approved safety tag.

Step 2

Remove the head cover.

Find cable 200 in the installation kit.

To install the cable, do these steps:

  • Open the control cabinet. Find the I/O PCB.
  • Connect the cable [1] to P35 on the I/O PCB.
  • Put the cable into the cable manager [2].
  • Put the cable through the cable carrier [3].
  • Examine the connector bracket [4] at the top of the spindle.
  • Find an open hole that has the label "SPARE."
  • Push the connector on the cable through the hole.

Step 3

Remove the modular-hose assembly [2] from the spindle head casting.

Install these parts for the P-Cool assembly:

  • tee fitting [1]
  • modular-hose assembly [2]
  • adapter [3]
  • P-Cool hose assembly [4]
  • P-Cool assembly [5]

Step 4

Find the P-Cool cable [1] in the installation kit.

Put the cable into the bracket [3] for the pipe fitting. You must turn the cable to put it through the bracket.

Connect the cable to the P-Cool unit [4].

Put a cable clamp [2] onto the cable. Attach the cable clamp to the spindle casting as shown.

Find the connector [5] on the other end of the cable.

Find the receptacle [6] on the connector panel at the top of the spindle.

Connect the cable to the receptacle.

Step 5

If the spindle head cover [1] has a plug [2] at the right rear corner, remove it before you install the cover.

Install the spindle head cover.

Attach the pipe bracket [4] to the spindle head cover.

The P-Cool cable has a special fitting [3] to prevent damage. Make sure the fitting is tight.

note: Machines made before August 2002 possibly do not have the plug in the spindle head cover. Refer to "Mini Mill, Super Mini Mill - P-Cool - Installation - Introduction" for instructions on how to modify the spindle head cover.

Mini Mill, Super Mini Mill - P-Cool - Flood Coolant Ring - Installation

Do this procedure on a Mini Mill or Super Mini Mill that was made after 2014. These machines have a flood coolant ring. This procedure tells you how to install a programmable coolant (P-Cool) system.

Step 1

Set the main circuit breaker to the OFF position.
Push POWER OFF.

Lock the main circuit breaker. Use an approved lock with an approved safety tag.

Step 2

Assemble the return assembly for the flood coolant ring. Do these steps:
  • Connect a straight compression fitting [1] to the return tube [2].
  • Connect a 90-degree compression fitting [4] to the return tube.
  • Connect an inline valve [3] to the fitting.

Step 3

Remove the plug [6] from the manifold [5] for the flood coolant.

Connect the return assembly [4] to the manifold.

Connect the P-Cool unit [1] to the P-Cool bracket [2].

Connect the hose [3] for the P-Cool to the return assembly [4].

Step 4

Remove the spindle head cover.

Connect the P-Cool cable [1] to the P-Cool unit [2].

Put the cable through the slot [4] in the spindle head casting.

Connect the cable to the open connector [3] on the connector bracket for the spindle head.

Install the spindle head cover.
