Magna ordered both ANGER HCXchange machines with control and drive technology from FANUC – it was not a new partnership for ANGER, as primarily components of the CNC world market leader were deployed there up to approx. 5 years ago. Roland Haas explains: "At that time, we were doing lots of work for the North American market, which mainly required FANUC controls. The cooperation with FANUC was very good for us. The overheads in the area of service and maintenance were minimal, and the products were absolutely reliable. Unfortunately, the recession in North America and in the automobile industry there caused the cooperation with FANUC to dwindle. So we at ANGER were very pleased about the order from the Magna Group to equip the ANGER HCXchange machines with FANUC. Because now we will have this reliable, strong partner back on board."
In addition to the implementation of the FANUC Series 31i CNC system, major attention was initially focused on the drive system of the machines configured according to the box-and box-system. A special feature, for example, is traversing in a horizontal direction, which is achieved via two ball screws in parallel operation. The object here was to choose the proper settings, and ensure reliable control adjustment. Finally, positioning accuracy in the µm range is required.
Another challenge were the third-party motors to be integrated
. Because ANGER implements proprietary hollow shaft servomotors
in its machine concept. Another issue was that four axes are used as standard on the ANGER HCX machines. A fifth axis is implemented in the clamping device upon customer request.
