oR

Our external milling machine configuration.

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.
