Multitasking – digital and ergonomic

The “Swiss army knife” of machining: This is the title given to Starrag’s Bumotec s191 mill / turn center thanks to its versatility. Three small letters now denote further development of this top model from the Swiss manufacturer: The Bumotec 191neo is just as versatile as its predecessor. But it is now even easier to operate, mainly thanks to the new Human Machine Interface (HMI).

Concentrated expertise packed into an ergonomic design

“How can we improve upon an extremely reliable, powerful and modular center, when it already offers the perfect solution for dealing with the various challenges encountered when machining precise, small parts with a high degree of added value?” This was the question the team at Starrag, composed of experts from production, process engineering, quality, application, service engineering and construction, asked themselves.

The answer is clear as soon as you look at the Bumotec 191neo: The new model combines concentrated expertise in an ergonomic housing. The large glass surfaces and optimally positioned access doors mean that the model offers a great view of the different areas of the machine and improved access for operators. The light strip allows users to immediately identify the operating status of the machine at a glance. The operator can easily switch between the screens using their finger.

You can track the progress of ongoing machining processes, configure the programming and monitor production – all in real time. All in all, the mill/turn center is intuitive and user-friendly, allowing operators to quickly become familiar with the machine. This is a significant advantage with the lack of highly skilled workers on the job market.

Highly flexible:

The Bumotec 191neo is not just a single machining solution, but is basically twelve different machines in one platform. This diverse range is the only way to meet the specific requirements of typical users in the fields of medical technology, micromechanics and the luxury goods industry in an economical and technologically optimal way.

The tool change time is reduced by around 15%, meaning tough demands relating to the cycle time are met and unproductive downtimes are reduced.

Precision machining with 12 different faces

Starrag offers the machining center in versions with a vice “P”, multipurpose pickup vice “PRM”, back-working spindle “R”, and with combined vice and back-working spindle “RP” and with a bar capacity of 1.65 in., 1.97 in. or 2.56 in. (42 mm, 50 mm or 65 mm). But the Bumotec 191neo is not just a machining solution – it offers twelve different machines in a single platform. According to Starrag, this diverse range is the only way to meet the specific requirements of typical users in the fields of medical technology, micromechanics and the luxury goods industry in an economical and technologically optimal way.

Unproductive downtimes are significantly reduced

Even without user intervention, the Bumotec 191neo operates in a stable, reliable and productive manner. The tool change time is reduced by around 15%, meaning tough demands relating to the cycle time are met and unproductive downtimes are reduced. Other advantages of the new model include the increased torque of the Starrag milling spindle and the pick-up unit, which operates 12% faster than before. The Bumotec tool magazine offers over 90 tool slots as standard and has tool breakage sensor which works in parallel, for when problems arise. In conjunction with a Bumotec palletizer or an automatic cell robot, continuous production can be performed around the clock, which may only stop preventive maintenance.

According to Starrag, the modular design means that a wide range of customer requirements can be met: A variety of peripheral devices are available, including temperature-controlled high-pressure systems, swarf conveyors and bar feeders. Users can machine a range of complex and demanding workpieces in a single clamping, because the Bumotec 191neo not only turns, mills, grinds and polishes, but it can also perform less frequently used machining processes such as hobbing, skiving and diamond cutting.

A machining center with built-in remote control

The new model offers the proven reliability and production stability of the Bumotec s191: It is designed to meet the challenges of digital transformation, as it can be used in conjunction with the latest production technology.
