4 2-speed gears The 2-speed gearbox is controlled by M-function. A headstock temperature control system guarantees no expansion of the main spindle unit, even after intensive heavy machining. Machinery construction All guideways are precision ground and hardened. The Y-axis has a 4 guideways. The ball screw mounts, as well as the axis motor flanges are an integral part of the casting which ensures an extremely rigid and precise axle movement, even for workpieces weighing up to 4.5t Ballscrew mounts are an integral part of the casting Control options Heidenhain Fanuc Mitsubishi

5 Various options for 4th & 5th axis Thermal stability by 3 separate cooling circuits The high-performance cooling system ensures optimum temperature stability of the main spindle (cooling circuit 1 & 2) and in parallel with circuit 3, it prevents a heat transfer of the main motor to the spindle. This innovative system ensures constant temperature conditions and high-precision milling. KTR couplings In all machines of the new Alpha Center series quality ROTEX GS KTR couplings are used. Coupling description ROTEX GS is a three-part, free of play under pretension, axial plug coupling. For critical applications they offer backlash-free torque transmission with rigidity and vibration damping. All machining centers measured by VDI DGQ 3441 and compensated Even a QC 10-circle shape is done
