Touch sensorAuto cutting-point measurement and tool offset/breakage detection

Hybrid coolantOkuma'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.

ABSO SCALE

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.

* A stand may be necessary depending on the type of conveyor. * Chip conveyors developed for machining hard materials are also available.

• Chip conveyor types and applications

Various chip conveyors

Versatile machining variations

• Hob speed 1,000 min-1

• Feedrate: 2 mm/rev (0.079 ipr)

Infrared in-process gaugingBy ATC-delivered, high-precision wireless touch sensor－ for superb auto work gauging (dual dia/radius gauging).

High-pressure coolantunit (7 Mpa specification)

High-pressure coolant flushes chips, eficiently cools tool tips, and extends tool life.

Bar feedersWith part catchers, long and automated operations also possible with the various bar feeder systems available.

OGL gantry loadersAble to handle a flexible arrangement of workpieces, Okuma gantry loaders help automate production lines, and with massive stackers provide long runs.
