Moving work pieces between operations, waiting, setups…
Waiting for machine, setup changes, non-cutting times…
Turn and mill operations + 5-axis control eliminate waste
and provide highly efficient production.

Faster axis feeds
32 m/min (X-Y-Z axes)
Max acceleration...	X axis : 0.21G
	Y axis : 0.57G
	Z axis : 0.35G

Shorter ATC time (C-C)
12.5 sec

Shorter B axis indexing
2.4 sec/90º

Circular cutting (X-Y planes)			B-axis control
Roundness: 2.1 µm (actual data*)			Standard: 0.001º orientation Optional: NC-B axis (simultaneous 5-axis control)

Machining dimensional change over time: 20µm*

Turning and milling with room temperature change of 8ºC (8hr)

Okuma´s Thermo-Friendly Concept incorporates advanced structural designing with field-proven thermal control technology to provide stable machining accuracy required by high-precision 5-axis multitasking applications. Turning-milling repetitions present no problem plus machine warm-up time to thermally stable level is reduced (cold start) and dimension control is easier.
