Bohle’s ENDURA 700Linear Gantry Milling Machine is the newest addition to a family of modular-designed 5-axis simultaneous, high-speed linear gantry milling machines by FOOKE GmbH. They are especially suitable for the efficient machining of five sides of parts made from plastic, composite materials (e.g. CFRP and GRP), ureol and aluminum, as well as for finishing cast and steel materials.
The ENDURA product line meets the need for extremely high-speed milling machines by aerospace, rail transportation, automotive industry and their subcontractors, as well as model-making, prototype construction, tool-making and mold-making.
These applications demand very tight positional control of milling tools in the workspace. In response, Fooke provided the first machine with VCS (volumetric compensation system) to the U.S. market. VCS is now available with either the Siemens or Heidenhain control.
The ENDURA 900LINEAR product line offers axis travel in X-direction up to 20 m, in Y-direction up to 4 m and in Z-direction up to 2 m. Larger, custom machines can be designed for specific applications.
The ENDURA 1000LINEAR product line offers axis travel in X-direction up to 120m and is frequently used in high-speed rail applications.
The use of linear motors as feed drive units eliminates several typical mechanical wear elements, including gears, bearings, ballscrews and rack-and-pinion systems, thus increasing drive rigidity substantially. This is, next to the rigid machine structure, the main reason for the dramatically increased machine dynamics: acceleration values of 5 m/sec on the path contour can be reached easily.
For even quicker performance in the ENDURA range, integration of linear motors into the rigid structures of machines can provide acceleration values of up to 10 m/sec.
