Plate Milling Machine ENDURA® 800
Highly dynamic and precise efficient milling machine in portal construction with two CNC controlled axis for rational machining of big sized aluminium plates of up to 3,000 mm x 6,000 mm.
Features, technique and equipment:
- portal (stationary):
pylons and Y-axis made of high-absorption hydropol concrete with steel core insert for taking up the Z-axis slide.
- machine bed:
the machine bed consists of a welded steel construction cast with special concrete, linear guides and a T-slot table. Max. table load approx. 10 to.
- z-axis slide:
designed as a low strain, annealed welded steel construction, hydraulic weight compensation, clamping unit for vibration damping, advance angle to prevent undercuts.
Axis drive technology:
air-cooled digital motors engage with the steering rack via a pinion gear mechanism. The motors are designed as gantry drives with master/slave.
Guiding of linear axes:
the linear axes are equipped with generously dimensioned, hardened and grinded, pre-tensioned, linear guide elements.
Working area enclosure, noise-insulating:
the working area is enclosed from all sides, open at the top, with doors at the front and back (at least 1 meter wide) with laminated glass windows.
Machine table features and technique:
the machine bed consists of a steel welded construction poured by special concrete. The machine table travels along the X-axis and consists of a high-absorption cast steel construction with T-slots for taking up the vacuum clamping plate (customer interface).
fully machined and assembled consisting of:
- 1 x basic structure (42CrMo4V) with max. possible tool-loading of
- 16 x roughing inserts with PCD WSP
- 4 x finishing inserts with PCD wiper insert
- 4 x dummy inserts
