Programmable Coolant (PCOOL) - Spigot Positioning

Applies to machines built from: 
January, 1992

Programmable Coolant - Spigot Positioning - Introduction

This procedure tells you how to find the best Programmable Coolant (P-Cool) spigot position for each tool. The P-Cool spigot adjusts its position when the program calls a tool offset.
caution: Do not move the P-Cool spigot by hand. This causes damage to the motor. Use only control commands.


Software Required:
  • Mill Software Version 4.19 or higher

Programmable Coolant - Spigot Positioning - Positioning

Step 1

Set the ball valve to the P-Cool position.


This step is necessary only when you have a ball valve control to change between conventional coolant (lock lines or coolant ring) or P-Cool.

Valve placement and style can be different from the illustration.

Step 2

Press OFFSET until the TOOL OFFSET table [1] appears on the display.

Command the first tool into the spindle.

Step 3

Press COOLANT to start the coolant flow.

Press CLNT UP or CLNT DOWN to change the position of the spigot [1].


Continue to the next step after you find a good position, where the coolant sprays on the tool tip.

Step 4

Press COOLANT to stop the coolant flow.

Record the value next to CLNT POS [1] at the bottom of the TOOL OFFSET table.

Step 5

Highlight the tool offset you want to adjust.

Select the COOLANT POSITION column [1].

Type the coolant position number that you recorded in step 4.

Press F1 to enter the value into the COOLANT POSITION column.

note: The P-Cool spigot adjusts to the position in the COOLANT POSITION column when the program calls a tool offset.

Programmable Coolant - Spigot Positioning - Other Positioning Methods

You can also use these methods of changing the position of the coolant spigot.
  1. Coolant Position System Variables
    • You can specify the coolant positions for tools 1 through 200. The systems variables you will use are 3401 through 3600.
    • Example: #3401=15 sets the coolant position for Tool 1 to position 15.
    • The machine must have Macros enabled.
  2. Coolant Position in the Program Blocks
    • You can adjust the spigot in a program block with an M34 or M35 command.
    • The M35 command moves the spigot one position up.
    • The M34 command moves the spigot one position down.

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
