Maschinenfabrik ALFING KESSLER GmbH

Final assembly of a 'FLEX' hardening machine


Our machine design offers maximum flexibility for including a wide range of crankshaft types and variants in the construction of truck engines in line with requirements. This allows optimum coordination between the cycle time and the required investment. The option of making subsequent adjustments to modified cycle time requirements enhances this flexibility.


  • Ideal ratio of machine size to crankshaft size
  • Loading via gantry systems or manual loading
  • Integrated and highly flexible heavy load system
  • Short conversion times and maximum user friendliness
  • Outstanding workstation overview
  • Maximum of three crankshafts in machine
  • Can be individually extended, e.g. with pre-washing, post-washing, tempering via residual heat, concentricity measurement, marking unit
  • Crankshafts up to a length of 1.5 m and a weight of 250 kg
  • Cycle time approx. 60 s
