TECHNICAL FEATURES
GENERAL FEATURES

The “HP line PLUS” 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
MACHINE STRUCTURE
  • Strong structures made of electro-welded and standardised steel formed with a "alveolar" pattern and with size 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 crossbeam is motorised with 2 servomotors per side, each with its own gear reducer/pinion, for better adjustment of the preload and recovery of clearances thereby maintaining precision and higher dynamic performance.
  • The system operating the axes on both sides is electrically synchronised (Gantry system), allowing for precision performance even at high speed and acceleration.
  • Also the movement of the carriage running on the crossbar, the "X" transverse axis, is controlled by 2 servomotors.
  • 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.
  • Measuring system with linear transducers: all linear axes are fitted with linear transducers with a direct and linear inductive measuring system.

 

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.

OPERATING UNIT

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

Direct measuring devices on rotary axes with angular transducers.
