� Chip conveyor types and applications

Various chip conveyors

GrindingGrinding with the M-spindle's cup grinding wheel

Blade machiningHighly accurate machining and synchronized control, even for highly accurate shaping of complicated blades

Eccentric cutting (cam)Eccentric cutting for cams and similar shapes can be programmed and machined very efficiently.

Helical cuttingDone with small-diameter rotating tools in big holes. Helical cutting on slopes also possible.

You can turn reverse tapers as shown below by drawing the B-axis gradually back along the slope at the desired angle.

B-axis reverse taper turning

44/80/120-tool ATCLarger tool capacity for wider range of machining

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

Hydraulic steadyrestIdeal for highly efficient

machining of long work-pieces.

ABSOSCALE

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 gaugingBy ATC-delivered, high-precision wireless touch sensor — for superb auto workgauging (dual dia/radiusgauging).

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.

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