Hybrid coolant
ABSO SCALE
Larger tool capacity for wider range of machining
Auto cutting-point measurement and tool offset/breakage detection
Okuma's hybrid coolant system lets you cut with oil and cool down with water, so you save coolant and extend the life of your tools.
This high-speed high-resolution [0.1 mm (4 min.)] optical absolute position encoder developed by Okuma improves machining accuracy by avoiding ball-screw thermal expansion and backlash.
Infrared in-process gauging
High-pressure coolant unit (7 Mpa specification)
OGL gantry loaders
Bar feeders
By ATC-delivered, highprecision wireless touch sensor − for superb auto work gauging (dual dia/radius gauging).
High-pressure coolant flushes chips, eficiently cools tool tips, and extends tool life.
Able to handle a flexible arrangement of workpieces, Okuma gantry loaders help automate production lines, and with massive stackers provide long runs.
With part catchers, long and automated operations also possible with the various bar feeder systems available.
