Nexturn SA(B) Swiss CNC lathe series represent a cost efficient and productive 7-axis machine for complex precision parts. Three models feature synchronous guide bushings, 7 machining axes and as many as 22 tools to handle maximum bar diameters of 12mm, 20mm and 32mm. Maximum turning lengths are 6.3″ on the 12mm machine and 8″ on the 20mm and 32mm models.
Built-in motor on main spindles range from 3 – 10 HP and maximum RPM capacity up to 10,000 RPMs, while sub-spindles offer 1.5 – 3 HP and up to at 10,000 RPMs. Both spindles have full C-axis with .001° positioning. Powerful live tools, operating at 1.3 HP and 6,000 RPMs allow for complex milling operations.
Excellent rigidity results from the use of FEA technology in the one-piece bed casting design. The machine design maximizes ease of use with ergonomically arranged controls and fully opening covers and doors.
