tions Manager Markus Kirchner, the machining operation has been almost routine: “We are using a speed of 800 rpm and a high feed rate. That is nothing special to us, but it results in significant time savings, higher precision, and we can use the same milling cutter for all types of components.” Considering all the efficiencies, when does a machining center with a work area of 2400 × 1600 × 1600 mm in XYZ axes provide a profitable solution? The company produces only five cas- ings per year that actually have these dimensions, but in the case of Knödler- Getriebe, the company wants to provide sufficient machining capability to be able to meet individual customer requests. The long traverse paths and high spindle power provided by the H 14000 were fully used for the first time ma- chining a large gear unit that provides 400,000 N•m torque with correspond- ing dimensions. Since the distance of the milling cutter to the spindle is dis- proportionately large and thus requires relatively high power, Werner Knödler thought about purchasing a special turning machine for milling of the cool- ing coils. However, to remain flexible in terms of their machinery, this became another reason to choose the H 14000. For the milling of the coils a spe- cial tool with a length of 600 mm is used. On a conventional machine it would not be possible to insert this tool in automatic mode. The large distance requires a spindle providing the corresponding stiffness and power. For Knödler that was just one of the numerous advantages of the H 14000: “Its power, the mechanical structure and statics as well as the fact that the workpiece moves towards the tool provide huge benefits also in view of the projection length. However, it is not our philosophy to operate the machine to its limits at all times. What is more
