»We have known HELLER for many years and appreciate the quality of their machines, since we subject them to very high volumes of machining every day. Our conviction that slideway guides are optimal for heavy machining long ago motivated us to retrofit and to have our HELLER BEA ranges overhauled on a regular basis. Since buying a HELLER MCH 450 with anti-friction guides, however, our viewpoint underwent a fundamental change. Based on our positive experience, our con fidence in HELLER and Siemens 840D sl control, we were upbeat that the H 14000 is the ideal complement to the range of our products. Especially since specific functions have now been improved based on past experience.« Werner Knödler, Managing Director

Power pack H 14000 – Its strength is in the detail

HELLER solutions at Knödler-Getriebe GmbH

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 the HELLER 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
