The “HPline” Machining Centre is a milling machine 5-axis on the tool and commanded by a NC, consisting of a structure with Cartesian axes and a mobile crossbeam:

• Moving crossbeam sliding on guides positioned on side pillars: "Y" longitudinal axis.
• The carriage of the “X” transversal axis, which moves the vertical arm for the Z axis, slides on the beam.
• The axis end is the fastening element of the operating unit.
• Separate worktop from the machine bases

• Structures formed with a "alveolar" pattern and whose size is based on the principles of FEM finite element analysis integrated with dynamic simulation
• Motion is transmitted by Brushless motors coupled to precision gear reducers with pinions fastened onto them and running on hardened and ground precision racks with helical teeth.
• The components slide on precision prismatic guides with pre-loaded recirculating ball runners.
• Full digital package: SIEMENS highly dynamic Drives and Brushless Servomotors.
• The brushless motors integrate the position data transmission system.
• The structures are already prepared for the optional implementation of direct measurement systems with inductive linear encoders.
• The crossbeam is motorised on both ends: the electrically synchronised two-axis movement system (Gantry system) allows for precision performance even at very high speed and acceleration.
• Also for vertical axis "Z", motion is transmitted by a double drive unit. Both motors are fitted with a brake and each one transmits motion on a rack: one on the right and one on the left of the vertical arm.
• This configuration with double pinion/gear reducer/motor provides improved electronic adjustment of the preload according to the different operating conditions applied, recovery of clearances thereby maintaining precision, and higher dynamic performance.

Perimeter protections:

At the front, 2 folding doors with manual opening and large inspection windows (laminated and tempered glass).  Optional feature of two doors at the back as well.

Dust protections:

• The runners have a double external protection consisting of special scrapers.

• All the guides and transmissions of the linear axes are covered with bellows.

HS678 Head

Universal head with 2 rotating axes at right angles and simultaneously controlled.

Motion is transmitted by a (Siemens) servo-assisted brushless motor providing programmable positioning in any point of the rotation.

Axes A and C are fitted with a pneumatic brake to lock the axes in a fixed position. This provides greater rigidity during machining that does not require the interpolation of these axes.

• Stall torque:   A =  470  Nm (1400 max)      C =   480 Nm (1450 max)
• Locking torque (brakes):  A = 1800 Nm     C = 1800 Nm
