Starrag Bumotec s1000C

The Starrag Bumotec s1000C is a transfer-line-style multi-station machining center designed for high-volume production of precision small parts in medical device, watchmaking, and automotive component sectors. Unlike the single-station s191 family, the s1000C arranges multiple machining stations in sequence, enabling simultaneous operations on different parts to achieve transfer-line throughput with CNC flexibility.

The s1000C features an electrospindle delivering up to 25,000 RPM with the more rigid HSK32 tool holder. XYZ slides with linear guides enable high feed rates, while direct-drive electrospindles reduce maintenance. Accelerometer-equipped spindles provide condition monitoring for predictive maintenance.

Starrag quotes up to 40% cycle time improvement compared to previous-generation transfer systems, with sectioning reduced by 30% and machining by 51%. The s1000C also achieves a 30% reduction in footprint compared to its predecessor. The machine inherits Bumotec’s Swiss precision heritage while targeting production volumes exceeding single-station capacity.

New machines typically price between $800,000 and $1,500,000 depending on station count and automation level. The s1000C competes with transfer machines from Tornos, INDEX, and Mikron.
