Overview

The Starrag Bumotec 191neo is the next-generation evolution of Bumotec’s legendary s191 platform, featuring a complete redesign with linear motor drives, an intuitive touchscreen HMI, and 12 possible configurations on a single machine platform. Built at Starrag’s Swiss facility, the 191neo targets medical, watchmaking, and precision micro-machining markets, delivering up to 40% faster cycle times through improved dynamics and reduced non-productive time.

The 191neo handles bar stock up to 42 mm, 50 mm, or 65 mm diameter depending on configuration, a significant increase over the original s191’s 32 mm capacity. The machine provides 5-axis simultaneous machining as standard, with expansion to 7 axes and 3 spindles. Tool capacity reaches up to 90 positions for complex multi-operation programs.

A new generation of linear motors replaces ballscrews on critical axes, delivering higher acceleration, better positioning accuracy, and zero backlash. The machine’s Windows-based PC HMI with touchscreen interface modernizes the operator experience. The modular platform concept allows configuration with counter spindles, vice/retaking units with 1-3 positions, high-pressure coolant, chip conveyors, and bar stock loaders.

New machines typically price between $600,000 and $1,000,000 depending on configuration. The 191neo competes with the Willemin-Macodel 508MT2 and INDEX R200 for high-precision complete machining of small complex parts.

Modern Windows-based touchscreen HMI improves operator efficiency
Up to 90-tool magazine capacity ensures complex programs run unattended

Limitations

Premium pricing above $600K reflects advanced linear motor technology
Linear motor drives generate more heat, requiring robust thermal management
12-configuration flexibility means longer lead times for non-standard configurations
Starrag/Bumotec service presence in North America remains limited

Best For

Medical device manufacturers requiring faster cycle times on dental abutments and spinal implants from bar stock up to 65 mm Swiss watch manufacturers upgrading from older s191 machines for 40% cycle time improvements High-volume precision connector manufacturers where linear motor dynamics improve per-part economics Aerospace micro-component producers where 7-axis capability eliminates re-chucking Contract manufacturers serving multiple precision industries benefiting from 12-configuration flexibility

Frequently Asked Questions

01 How is the 191neo different from the original s191?

The 191neo features linear motor drives, Windows-based touchscreen HMI, expanded bar capacity up to 65 mm, 12 possible configurations, and up to 40% faster cycle times.

02 Why does the 191neo use linear motors?

Linear motors provide zero backlash, higher acceleration, better positioning accuracy, and reduced maintenance since there are no wear components.

03 What bar stock sizes can the 191neo handle?

Up to 42 mm, 50 mm, or 65 mm diameter depending on configuration.

04 Can the 191neo run unattended?

Yes. With up to 90-tool capacity, bar stock loader integration, and counter spindle options, the 191neo is designed for extended unattended production.
