C 50

OERLIKON Bevel Gear Cutting Machine

Highly efficient, environmentally friendly dry-cutting

The vertical design of the C 50 bevel gear cutting machine and the direct drives for the tool, workpiece and angle drive make it ideal for dry-cutting bevel gears with coated carbide cutters. The C 50 is designed exclusively for dry-cutting processes. When used in conjunction with the high-performance ARCON® and SPIRON® cutters, the bevel gear cutting machine can be used to produce all common spiral bevel gears in both continuous indexing and single indexing processes with maximum efficiency.

Optimal chip flow thanks to vertical axis concept

Highlights

OERLIKON Bevel Gear Cutting Machine C 50

Optimal chip flow thanks to vertical axis concept

  • Minimal heat input thanks to systematic avoidance of chip deposits in the working chamber
  • Separate working chamber to protect drive components
  • Foundation for trend-setting high-speed machining
  • Improved axis arrangement allows for optimal process Monitoring
  • Moving parts protected from damage caused by chips both inside and outside the working chamber
  • Optimal energy efficiency thanks to recovery and on-demand control of units
Minimal setup times

Highlights

OERLIKON Bevel Gear Cutting Machine C 50

Minimal setup times

  • Vertical axis concept makes it easy to access the workpiece clamping device
  • Bayonet connector speeds up clamping device changes
  • Integrated workpiece measurement system for automatic quality monitoring and faster production release following a component change
  • Blade breakage monitoring allows for fast response to minimize downtime
Intelligent production process for maximum efficiency

Highlights

OERLIKON Bevel Gear Cutting Machine C 50

Intelligent production process for maximum efficiency

  • Temperature compensation inside the machine ensures maximum precision
  • Short processing times and low tool costs make for extremely economic production processes
  • Intuitive operating concept
  • Top-notch quality through automatic pitch compensation in the face milling process via software settings
  • Investment protection provided by tool breakage monitoring
Energy efficiency (e²) for maximum savings

Highlights

OERLIKON Bevel Gear Cutting Machine C 50

Energy efficiency (e²) for maximum savings

  • As-needed control of the chip conveyor with energy-saving stand-by mode
  • Energy-saving cooling technology thanks to effective control of the cooling units
  • High-efficiency-class motors
  • Intelligent reactive current compensation
  • Efficient energy recovery
Minimal auxiliary times thanks to integrated workpiece change

Highlights

OERLIKON Bevel Gear Cutting Machine C 50

Minimal auxiliary times thanks to integrated workpiece change

  • Optimized workpiece changes, since loading system is fully integrated into the machine
  • Automation interface in accordance with VDMA directive 34180
  • Integrated NC axes means intelligent coordination of the machining process and workpiece changes
Closed Loop technology on the machine with the integrated KOMPASS measurement system

Highlights

OERLIKON Bevel Gear Cutting Machine C 50

Closed Loop technology on the machine with the integrated KOMPASS measurement system

  • Series production control at the press of a button by means of a network to KOMET. Correction of flank profile deviations and tooth thickness based on certified P machine measurement
  • KOMPASS startup control at the press of a button through machine-integrated measurement option, and subsequent KOMET correction directly on the machine
  • Flank shape measurement of a component cut with allowance against nominal
    measured data adapted automatically to this allowance
  • Highlight: automatic pitch compensation immediately following pitch measurement for components produced using the single indexing method
Flexible deburring

Highlights

OERLIKON Bevel Gear Cutting Machine C 50

Flexible deburring

  • Visualization of the deburring paths ensures collision protection between the deburring tool, bevel gear cutting machine, and component
  • Early-stage validation of production equipment and fast deburring setup, since all deburring development takes place outside the cutting machine
  • Easy loading of centrally stored deburring processes minimizes tooling time during setup
  • Deburring calculation for flank profiles of various manufacturing methods
