Service How To Procedures Programmable Coolant - Spigot Positioning
Last updated: 11/30/2018

Programmable Coolant - Spigot Positioning

Applies to machines built from: January, 1992

Introduction

1

This procedure tells you how to find the best Programmable Coolant (PCOOL) spigot position for each tool. The PCOOL spigot adjusts its position when the program calls a tool offset.

 Caution: Do not move the PCOOL spigot by hand. This causes damage to the motor. Use only control commands.

Software Required:

  • Mill Software Version 4.19 or higher

Positioning

1

Set the ball valve to the PCOOL position.

 

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

Valve placement and style can be different from the illustration.

2

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

Command the first tool into the spindle.

3

Press [COOLANT] to start the coolant flow.

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

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

4

Press [COOLANT] to stop the coolant flow.

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

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 PCOOL spigot adjusts to the position in the COOLANT POSITION column when the program calls a tool offset.

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.
