UAD Technology

Indexing heads that are ideal for all types of machining operations, including large stock removal, hard materials, long tools and long 3D finishing operations, etc. This technology is applied in two different geometries:

  • Universal Head at 45º. Compact, robust.
  • Orthogonal head at 90º. Flexible, easy to program. Can reach negative angles of up to 45º.

Flexibility

  • Rotation/indexation every 0,02º thanks to the double Hirth coupling patented worldwide
  • 6.000 rpm with no limitations
  • Adjustable coolant through spindle 17 - 70 bar

Reliability

  • Design and fabrication entirely by NCSA. The whole assembly process is monitored by NCSA
  • Head assembly in a cleanroom with constant temperature 22ºC
  • Milling head run in the test bench
  • 60 hours performing body & spindle rotations

Robustness

  • 4+2 bearings in the main spindle
  • Tool clamping force: 2.500 kg
  • Hirth couplings locking force: 22.000 kg
  • The milling head design allows 52 kW – 1.375 Nm in S1
  • Milling head body made of Casted Steel GGG-50

Precision

  • Maximum coupling repeatability error + - 3”
  • The bearing´s cages of the main spindle & the external spacers of the secondary axes bearings, are cooled with water

E5E Technology

Head with two continuous axes, ideal for machining with 4 or 5 continuous axes, as well as for super finishing operations in 3+2 axes. We offer 3 electro-spindles with different torque-power specifications designed for different applications.

  • Machining of monolithic aluminium parts for the aeronautic industry.
  • Machining of dies and moulds for semi-finishing and finishing.
  • Machining of dies and moulds for high-speed roughing, semi-finishing and finishing.

Flexibility

  • C axis rotation range, from -200º to +200º Option: -360º to +360º
  • B axis rotation range, from -110º to +110º
  • 3 electro-spindles can be installed in the E5E Head.
  • Coolant and/or air trough spindle adjustable from 17 – 70 bar

Reliability

  • Design and fabrication entirely by Nicolás Correa. The whole assembly process is monitored by Nicolás Correa
  • Head assembly in a cleanroom with controlled temperature 22ºC
  • Maintenance free, lubrication processes automatic

Productivity

  • C axis rotation speed: 45 rpm
  • C axis acceleration: 10 rev / seg2
  • B axis rotation speed: 25 rpm
  • B axis acceleration: 10 rev / seg2

Robustness

  • C axis working torque: 2200 Nm(Motor-Torque)
  • C axis torque with brake activated: 4000 Nm
  • B axis working torque: 2026 Nm (Motor + reducer + gears)
  • B axis with brake activated: 4000 Nm
  • Top Class electro-spindle manufacturer Kessler o Fischer

Precision

  • Distance between the nose and the B axis variable according to main bearings temperature.
  • Ps average error (according to VDI 3441) < 0,001º
  • Total positioning error P (according to VDI 3441) < 0,002º
  • B axis encoder located in the final rotating axis.
  • B axis transmission completely symmetric. Heat generated due to B axis transmission is equally distributed around the milling head.

Range of heads

Nicolás Correa has developed one of the widest ranges of heads on the market. All the heads in our range can be interchanged automatically, thanks to our Automatic Head Change system.
