Haas CNC Centers: Automatic Programmable Coolant Nozzle for Precise Tool Cooling

Worrying about coolent nozzle adjustments for different tools of multiple lengths, here is a good news,

Haas CNC vertical and horizontal CNC machining centers (VMCs and HMCs) are available with a Programmable Coolant Nozzle (P-Cool) that automatically directs coolant precisely at the cutting area for each tool.

Programmable Coolant Nozzle eliminating the need for constant adjustments of coolent nozzle by the operator.

Programmable Coolant Nozzle is controlled automatically by the part program.

Programmable Coolant Nozzle can be adjusted from the keypad while the program is running.

How to Set-up Programmable Coolant Nozzle Position for Each Tool

The position of the P-Cool nozzle for each tool is specified by entering the appropriate number in the Coolant Position column of the Tool Offsets table.

Adjustments of Programmable Coolant Nozzle

The position of the Programmable Coolant Nozzle can be adjusted while program is running

using the CLNT UP and CONT DOWN keys.

Controlling Programmable Coolant Nozzle with CNC M-Codes

The P-Cool nozzle can also be moved incrementally using M-codes within the program.

Inserting an M34 in the program cause the nozzle to increment down one position.
inserting an M35 will increment the nozzle up one position.
