Customer-specific solutions with measurable results

Gearboxes for up to 1000kW and with torques up to 400,000Nm are the Knödler-Getriebe GmbH calling cards. The primary motivation for the investment in a globally first 4-axis machining centre model H 14000 of theHELLER superlative, was to create universal and reliable reserve capacity.

Task Setting

  • Manufacturing of gears with torques from 500 to 400,000Nm and weighing up to 12t
  • Everyday subjection to very high volumes and a high chip removal rate
  • Long service life and highest precision of the machine
  • Universal flexibility with adequate reserves for individual customer demands

Project scope and solution

  • H 14000 with a rated torque of 2300Nm, a 4-speed gearbox working unit and HSK-100 spindle taper

Result

  • The output, the mechanical construction and the structural loading stand for the sustainable use of the machine
  • Using the H 14000, bearing seats of up to 600mm in diameter were for the first time pre-milled using a porcupine cutter, before final circular milling with a special solid carbide end mill cutter. The results are reflected in the measurement records – 5μm roundness and excellent surface finish with Rz in the range 6 to 8μm
  • The H 14000 also has spare capacity for applications such as milling of cooling coils, where a 600mm long projecting special tool is used
