What to Look for When Buying a Used Klingelnberg
Klingelnberg gear machines are engineered for precision production across bevel and cylindrical gear applications. Here is what to inspect on used units.
On Oerlikon bevel gear cutting machines, check the cutter spindle and workhead. Measure cutter spindle runout across the full speed range. On the vertical C series, verify workhead indexing accuracy and the integrated deburring station. Run a test cut and check tooth contact pattern with marking compound. On dry-cutting configurations, inspect chip evacuation and thermal stability.
On Höfler cylindrical gear grinders, verify the grinding spindle and dressing system. Test wheel spindle runout, vibration, and thermal behavior after warm-up. On VIPER 500 models, confirm quick-changeover between generating and profile grinding. On RAPID machines, verify all axis drives and the internal grinding arm if equipped. Inspect the diamond dressing roll for wear.
On precision measuring centers, confirm probe calibration and axis accuracy. Run a known master gear through the full inspection cycle and compare to certified values. Verify rotary table indexing and 3D scanning probe function. On machines with optical capability, confirm sensor alignment.
Identify the CNC platform and software version. Klingelnberg machines use Siemens Sinumerik 840D controls with proprietary software (KIMoS for bevel gear design, Gear Operator/Gear Production for cylindrical machines). Software version determines Closed Loop compatibility.
Oerlikon Bevel Gear Machines
C Series (Cutting) & G Series (Grinding)
The Oerlikon C series (C 30, C 50) uses a vertical concept for CNC spiral bevel gear cutting with dry or wet processing. The C 30 handles automotive bevel gears; the C 50 covers commercial vehicle and industrial sizes. Both support ARCON and SPIRON cutter head systems with continuous and single indexing. The G series (G 30, G 35, G 60, G 80) provides hard finishing of spiral bevel gears, with the G 35 targeting aerospace and the G 60/G 80 handling workpiece diameters up to 600 and 850 mm. All feature vertical grinding spindles and CNC diamond dressing.
Höfler Cylindrical Gear Grinding Machines
RAPID Series
The RAPID series (RAPID 650, 800, 1250, 2500, 3500, 5000, 8000) covers generating and profile grinding of cylindrical gears up to 8,000 mm diameter. These machines serve wind energy, mining, marine, and heavy industrial gearbox applications. Optional internal grinding arms extend the work range to internal gears. The RAPID platform's modular design accommodates a wide variety of workholding and automation configurations.
VIPER 500, Speed Viper & HELIX
The VIPER 500 grinds workpieces up to 500 mm in profile (K), generating (W), or combination (KW) modes with less than five minutes changeover time. The Speed Viper (80, 180, 300) delivers high-volume automotive generating grinding, with dual-spindle configurations (Speed Viper²) that minimize non-productive time. The HELIX 400 handles profile and generating grinding of larger cylindrical gears. The R 300 roll testing machine supports all five roll testing methods in a single platform.
Klingelnberg Precision Measuring Centers
The P series (P 16, P 26, P 40, P 65, P 100) provides fully automatic CNC gear inspection for workpieces from 160 mm to 1,000 mm diameter. These machines measure cylindrical gears, bevel gears, worms, hobs, and rotationally symmetrical components with optical and tactile probing modes. Surface roughness measurement capability and the award-winning Done-in-One concept enable complete inspection in a single automated cycle, making the P series a standard in gear quality labs and production environments worldwide.

Frequently Asked Questions About Used Klingelnberg Machines
Are used Klingelnberg machines reliable?
Yes. Klingelnberg has manufactured gear equipment since 1863 and is a global leader in the field. Machines are built in Germany and Switzerland with thermostable beds, direct-drive spindles, and vibration-damping mineral-cast or cast-iron construction. The integrated Closed Loop quality system ensures consistent precision from design through cutting, grinding, and final inspection.
What CNC controls do Klingelnberg machines use?
Klingelnberg machines use Siemens Sinumerik 840D controls with proprietary software. Bevel gear machines run KIMoS. Höfler cylindrical grinders use Gear Production or Gear Operator. P-series measuring centers run Klingelnberg's own measurement and analysis software.
What is the difference between Klingelnberg, Oerlikon, and Höfler?
They are all part of the same company. Klingelnberg (founded 1863, Germany) acquired Oerlikon Geartec AG (Zurich, Switzerland) in 1993 and Höfler Maschinenbau GmbH (Ettlingen, Germany) in 2012. Used machines may carry any of these names depending on the product line and year of manufacture.
What should I inspect before buying a used Klingelnberg?
On bevel gear machines, check cutter spindle runout, workhead indexing, and run a test cut. On cylindrical grinders, verify grinding spindle condition, dressing accuracy, and axis backlash. On measuring centers, run a master gear through the full cycle and compare to certified values.
What Klingelnberg models hold their value best?
Oerlikon C 30 and C 50 bevel gear cutters hold strong resale values. VIPER 500 and RAPID cylindrical grinders are in steady demand. Speed Viper machines command premiums for automotive applications. P 26 and P 40 measuring centers maintain demand for production and lab use. Call (844) 478-8181 for current valuations.
What industries use Klingelnberg machines?
Klingelnberg equipment serves automotive and commercial vehicle drivetrain production, aerospace gearing, wind power gearbox manufacturing, marine propulsion, mining, robotics, and the electromobility sector.
