3ATC Electrospindle

for compact tapping machinig centers with "revolver" style automatic tool change system

Brushless DC Motors

  • No special maintenance needed
  • Longer lifespan guaranteed

Motors for machinig up to 60.000rpm and 80.000 rpm

  • iSpeed Series with 150W Power

No thermal expansion

  • More accurate machining

Ceramic bearings

  • Optimal solution for continuos machinig, with less vibrations due to high temperatures and high rpm compared to traditional bearings

Less than 1 micron run-out

  • Maximum accuracy during maching
  • Extended tool life

BT30 Shank


  • The rotary joint mounted on the revolver of automatic tool change gives power to the electrospindle and assure pressurization and cooling to the system
