oR
The oR series of machines have been developed applying extensive know-how of high productivity systems for steel and cast iron crankshafts and camshafts.
Based on a milling center configuration and our experience with the XFlex series, it is equipped with 2 sliding NC controlled workpiece driving spindles, a NC independent steady rest, and 2 external milling tool spindles, offering extra capabilities and flexibility.
Thanks to its modularity, it is prepared to be retooled into an internal milling machine or a turn / turn-broach machine.
Our unique configuration allows for an increased machine stiffness, improved chip shedding, and a safe and easy access for maintenance.
- High level of modularity between ID, OD and TTB.
- 2 sliding NC controlled workpiece drive spindles. Electronic spring to control force between centers.
- Standard off the shelf pull-down and compensating clamping chucks, with fixed centers. Fully sealed and low maintenance.
- Highest stiffness of workpiece spindles, due to reduced overhang length from chuck face to guiding.
- Highest stiffness of tool spindles, due to bigger bearings.
- Automatic tool clamping.
- Low maintenance components, as the Direct Drive motors for workpiece spindles.
- Design focused on favoring chip shedding.
- Ergonomic design for tool change and maintenance activities.
- 9 axes machine: 7 linear axes provided with linear scales and 2 rotary axes for workpiece drive equipped with direct angular encoders.
- Workpiece Direct Drive by torque-motors.
- Fixed centers in both chucks with no hydraulic sliding and chip build-up.
- Steady-rest NC controlled in an independent slide.
- Tool clamping with automatic high force draw-bar.
- Part and tool settling control.
- Tool drive by Main spindle motors, with speed full range adjust thru electronic driver.
- Increased stiffness of the machine configuration.
- RFID of OD tools.
- Higher stiffness of tool spindles, by a big ASA cone and increased face support.
- Unobstructed chip shedding designed for dry machining.
- Totally sealed stainless steel front guarding with no horizontal surfaces.
- Honeycomb bed design so chips fall directly to the conveyor.
Machining units
- 2 NC controlled workpiece units (W1, W2).
- 1 NC controlled independent steady rest (W3).
- 2 NC controlled tool units (Z1/X1, Z2/X2), equipped with S1/S2 milling spindles.
- Reduced overhang distance from chuck face to front bearing and its guiding on the column.
Fixture
- 1 part per fixture.
- Rotary axes: synchronized C1 / C2.

a) Rotating pre-locators, fixed to the chuck.
b) Stationary pre-locators, fixed to workpiece spindle-housings.
c) Retractable pre-locators, for improved chip shedding.
Options
- OD tool monitoring for single insert breakage detection.
- Vibration monitoring.
- Tool temperature monitoring.
- Spindles main bearings temperature monitoring.
- Torque-motors temperature monitoring.
