The five-axis machining centers are said to be well-suited for automobile suppliers and those in contract manufacturing, tool construction, and the pump and fitting sectors.
Because of its position close to the operating point, the stiff spindle axis increases machining accuracy and precision. Combined with an overhead machining method, the chips fall away from the part, reducing the thermal load in the part. The linear guidance system of the reference axis can be equipped with a temperature-controlled cooling function. The machines are available with either Siemens or Heidenhain CNCs.
A laminated glass safety screen and a wide-opening work area door provide safe access and ergonomic operation. In addition to the basic machine, which can be equipped with a decentralized work area extraction system and automatic work area door, users can also select from various options for the tool magazine, cutting fluid systems, software and other accessories.
