Bumotec 191neo

Extremely stable during production with a minimum of operator intervention

Its man-machine interface switches from one screen to another with a simple swipe so that the machining operations in progress can be monitored, programming parameters can be viewed, and production can be tracked in real time

Designed with reduced consumption in mind, confirming Starrag's desire to develop new equipment which respects the environment


Bumotec Automation Solution


High-precision multi-task production center

Extremely stable during production with a minimum of operator intervention, the 191neo offers a formidable level of productivity. Its responsive tool change, the high torque of the Starrag milling spindle, and its thermal signature inherited from the original s191 model, ensure it maintains the programmed production rate and obtains a high finish quality, regardless of the material and complexity of the part to be machined.

Equipped with "à la carte" peripherals, such as temperature-controlled high pressure, chip conveyor and bar loader, the modularity of the 191neo ensures all production requirements can be met. Coupled with the Bumotec palletiser or with a robotic, modular or custom-made automation cell, this gives you access to "24/7" type production, which is only interrupted by preventive maintenance when required. In addition to milling and turning, it can also be used for grinding, polishing, skiving, gear hobbing and diamond cutting, thereby allowing complex, demanding parts to be completed in a single cycle.

Its man-machine interface, developed on a Windows-based PC application, with support for field technicians, switches from one screen to another with a simple swipe so that the machining operations in progress can be monitored, programming parameters can be viewed, and production can be tracked in real time. Intuitive and easy to use, it requires less training, thereby allowing it be used by operators with a lower skills base.

The s191 model has evolved...:

  • Complete machining solution
  • Production from bars or blanks
  • New generation linear motors
  • Up to 7 axes and 3 spindles
  • 5 simultaneous axes
  • Up to 90 tools
  • Peripherals include high-pressure equipment, chip conveyors and bar stock loaders
  • New MMI touchscreen with Windows-based PC
