Tornos MultiSwiss 8x26

With eight spindles, 18 linear axes and 31 tool positions, the Tornos MultiSwiss 8x26 is the model in the range for parts with many operations. Bar capacity runs from 8 to 26 mm and part length is up to 65 mm. Every spindle delivers 11.00 kW and 17.30 Nm at up to 8,000 rpm.

Two extra spindles change how a job is laid out. Main operation works with 7 cross slides plus 1 for cutting, where the MultiSwiss 6x32 on the same footprint has 5 + 1. Because the longest station sets the cycle on a multi-spindle machine, a deep hole or a long turning pass can be divided between two stations, and operations that would otherwise go to a second machine can stay in the cycle. Y axes are listed as 3 / 6 (option). Ask Tornos which of the two counts a given configuration carries before planning milled features around them.

The back side is handled by a pick-off spindle with the same 8,000 rpm and 11.00 kW as the main spindles but less torque, 12.00 Nm, and a Z stroke of 150 mm. Up to 4 tools serve back operation. On the main side the Z stroke is 75 mm and the maximum remnant length is 118 mm.

This is a big installation: 9000 mm long, 2260 mm wide and 2160 mm high, 15,000 kg, and 140 kW of installed power. The oil tank holds 2000 l with 50 μm filtration and a standard pump flow of 140 l/min. High-pressure pump option A is listed at 35 l/min and option B at 37 l/min. The control is programmed with TB-DECO ADV on an integrated PC.
