Complete complex parts in one set-up from a blank or a short bar
Machining of hard material such as tough ceramic
A wide range of processes and multiple machine configurations (fixed machining table, Axis rotation with multiple clamping systems,…)
BUMOTEC MACHINING CENTERS INCLUDING AUTOMATION SOLUTIONS
The Bumotec s191V is the combination of proven Swiss made mechanics and state-of-the-art CNC control and drive technology. With the CNC Bumotec s191V mill / turn center, precise and complex components can be produced via 5-axis machining. Thanks to its stable mechanical concept and its linear drive technology, accuracies of just a few microns can be achieved. The integration of an individually adaptable automatic workpiece change unit, allows the machine to be used for one off prototypes or to run so called «unmanned shifts» without personnel. Many different configurations are available with three to five axes of machining capacity. The thermal stabilization unit almost eliminates warm-up cycles when starting or after machining interruptions.
Features
FANUC 31i control
Ease-of-use Bumotec has developped a vast array of smooth interactive subroutines, helping to simplify the programming.
All machine setting A lot of the menus are dedicated to the basic characterictics of the machine. So, the machining programs are not relating to the specific machine data - full interchangeability between the machines is given.
A set of dedicated options, designed to the machining of ceramic and other hard materials, is available.
The tool magazine
Tool Magazine with 30, 60 or 90 tool pockets. All tools, regardless of milling or turning, are stored on 30 pocket discs. The tool return always to their initial position. Tool change in 1.8 sec. Very good accessability to magazine out of working zone.
Special tool holders 2-, 3-, or 4 cutting tips tool holders increase productivity, as they are used like a turret in the working spindle, thus saving a lot of tool-change-time.
A vast range of equipments to even more increase the S191 performance.
Automation A completely integrated loading/unloading unit enables highest autonomy at lowest invest. No referencing needed when changing parts. Parts handling through spindle grippers in the working spindle ( stored in the tool magazine ). Simple use of the machine axes. The pallet magazine can store raw parts as well as rapid indexing pallet systems such as 3R, Mecatool, Yerly and others.
Integration Bumotec integrates on customers demand other loading / unloading solutions.
Oil-Air mist lubrification To achieve longevity, the high spindle rpm‘s demand a top notch lubrification. The direct injection of an oil-air mist into the bearing is the solution.
Leak proof spindle nose Sealing air supports the labyrinth joint in terms of tightness.
Speed and longevity The hybrid bearings ( ceramic balls ) allow upscale spindle speed at minimal wear, supplying a high rigidity.
Spindle interlocking A ingenious locking mechanism assures the perfect mechanical indexing of nonrotating tools ( turning ), disengaging the hybrid bearings of the milling spindle - leading possible shocks and load through the spindle housing. Indexing increments of 45°.
Accessories for main spindle and retaking spindle A vast range covers all clamping requests for blanks or bars. Integrated stoppers associated to a clamping pressure allows to fix the most delicate or massive part.
Clamping systems for retaking units Vices, collet systems or tailstocks are available. Customers special systems can be integrated when needed.
Modularity The majority of all clamping devices can be interchanged between the spindles and retaking units.
The Bumotec S191 is the result of blending «Swiss» mechanics and state-of-the-art axis drive technologies. The cast iron machine base and travelling column eliminate vibrations in a perfect way. The advanced cinematics allow the implementation of numerous machining operations at a very small footprint.
Swiveling B Axis
Linear Motor Drive Option for the Z and Y axis Linear motor slides provide a step up in production speed, quality and stability while eliminating maintenance.
