Mazatrol Fusion 640
The transitional control between the T-Plus generation and Matrix
Mid 2000s
What Fusion 640 is
Fusion 640 was Mazak's transitional Mazatrol on the way to Matrix. You'll see 640T on turning machines and 640M on mills, plus a Fusion 640MT for multi-tasking. It introduced more modern parameter management and improved tool data screens.
Fusion 640 had a shorter shelf life than T-Plus or T-32 — Matrix came along quickly and the install base flipped. But you'll still find Fusion 640 machines on shop floors, and the conversational logic carries over cleanly to anyone trained on T-32 or Matrix.
What distinguishes Fusion 640
- Bridge generation between T-Plus / T-32 and Matrix
- 640T for lathes, 640M for mills, 640MT for multi-tasking
- Refined parameter management vs T-32
- Older Quick Turn and Slant Turn iron commonly ran Fusion 640
