Bumotec s191H (32mm / 50mm / 65 mm)

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.

• Complete machining solution
• Turn-mill and multiple other operations
• Working from bar or raw parts
• 5 axes simultaneous machining
• Up to 7 axes and three spindles

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.

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.

FANUC 31i control

• State-of-the-art control technology
• Smooth Bumotec man-machine-interfaces

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.

Swiveling B Axis

• Direct drive with 226 or 339 Nm:
• Paramount machining precision
• Improvement of surface quality
• Dynamic movements ( 0° to 90° in 0.35 sec )
• Utterly free of backlash
• No deterioration/wear over time

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.

• Higher precision an repetability
• Better surface finish
• Faster cycle times
• Reduced Maintenance

The Additional Advantage of Speed

• Reduction of bi-times
• Better dynamics and finishes at higher speeds.

A set of dedicated options, designed to the machining of ceramic and other hard materials, is available.

• HF spindle (150,000 rpm)
• Laser tool check
• Working zone entirely in stainless

The tool magazine

• 30 / 60 / 90 tool pockets
• HSK40 or Capto C4

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.

• Fixed touch probe
• Spindle probe
• Automatic barfeeders
• Chip conveyors
• Paperbond chip conveyor
• Parts Conveyor
• High pressure coolant pump\n

• Superior spindle speed and torque
• Outstanding rigidity

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°.
