Doosan TT Series M-Code List (Upper & Lower Turret) – Complete Reference for CNC Programmers

Doosan TT Series M-Code List (Upper & Lower Turret) – Complete Reference for CNC Programmers

Programming a twin-turret CNC turning center requires accurate control of both the upper and lower units. The Doosan TT Series M-Code List is an essential reference for CNC machinists, programmers, and machine operators working on Doosan PUMA TT-series turning centers. These M-codes control critical machine functions such as spindle operation, coolant, parts catcher, air blow, synchronization, and auxiliary functions for both the upper and lower turrets.

In this guide, we've compiled the complete M-code list for the Doosan TT Series, with separate commands for the Upper Unit and Lower Unit, making it quick and easy to reference while programming or troubleshooting. This list applies to popular Doosan PUMA TT-series machines, including:

• Doosan PUMA TT1500MS / TT1500SY
• Doosan PUMA TT1800MS / TT1800SY
• Doosan PUMA TT2000SY
• Doosan PUMA TT2500MS / TT2500SY

Whether you're writing new CNC programs, modifying existing code, or learning to operate a dual-turret Doosan lathe, this reference will help you understand the machine's M-code functions and improve programming efficiency.
