SF-25

Turning center for small precision parts

Multitalent for medical, aviation and automobile industry, this machine is the technical highlight of newest generation.

Based on technology of CNC automatic lathes, high precision and enhanced production of complicated and odd-shaped parts is achieved by the tool spindle.A back-chuck unit mounted on the tool spindle allows machining of all six planes of odd-shaped parts and complex parts up to Ø 25 mm.

10-station turret with single driven stations
Pivoting tool spindle with B-axis up to 20'000 rpm, Capto C3 collet unit and 5.5 kw motor
24-station tool changer for tools and pick-up unit
Available with pick-up collet unit (standard) or 3-jaw chuck (option)
Including high-pressure unit for an optimal cooling of tools
