used Gantry-high-bed Portal Miller FOOKE ENDURA 704 LINEAR

manufacturer: FOOKE
type: ENDURA 704 LINEAR
built: 2015
control: HEIDENHAIN iTNC 530 HSCI

Highly dynamic Gantry-high-bed Portal Milling Machine in compact design
Portal moving in X direction
Machine bed in rigid cast iron, side walls, cross slide and portal as welded steel construction, walking beam in cast iron.
Foundationless installation of the machine. Due to the inherently rigid machine bed, only a standard industrial floor,
approx. 300 mm thick, steel-reinforced, is sufficient for installation. A special foundation, however, is not required.
The machine is installed and aligned by means of fixators with anchor bolts.

• Highly dynamic Gantry-high-bed Portal Milling Machine in compact design
Portal moving in X direction.
• Machine bed in rigid cast iron, side walls, cross slide and portal as welded steel construction, walking beam in cast iron.
• Foundationless installation of the machine. Due to the inherently rigid machine bed, only a standard industrial floor, approx. 300 mm thick, steel-reinforced, is sufficient for installation. A special foundation, however, is not required. The machine is installed and aligned by means of fixators with anchor bolts.
• The linear axes (X,Y,Z) are equipped with water-cooled linear motors made by SIEMENS. The X-axis is designed as a GANTRY-axis.
• The linear and rotary axes are equipped with direct measuring systems.
• The Z-axis drive is supported by highly dynamic pneumatic cylinders (weight compensation).
• The linear axes are equipped with a safety system which brakes and safely holds the axes in case of voltage loss. The linear axes are equipped with hardened and ground, backlash-free preloaded linear-guideways.
• The guideways are protected by bellows.
• All guideways as well as the counterbalance cylinders, which have to be lubricated with grease or oil, are equipped with catching systems so that excess lubricant is collected in a controlled manner and the workpieces cannot be contaminated. The workroom is closed all around.
• A top cover prevents dust form escaping unhinderd from the work area and also limits the upward flight of chips.
• The front part of the cover (loading side of the machine) can be manually unlocked or locked so that the machine can be loaded and unloaded by crane or forklift truck.
• The working area is illuminated with fluorescent tubes (IP 54, protected against water jets and solid foreign bodies).
