BFR2

5-Axes in the basic version

Stable basic concept for coping with high machining forces.

The generously dimensioned machine concept with flat guides guarantees dimensional stability and smooth running even under extreme cutting forces. 5-axis machining centers are subjected to more complex loads than other machining centers due to their significantly larger technology spectrum. All forces occurring during multi-axis or simultaneous machining have therefore already been taken into account in the dimensioning of the machine cross-section. The machine concept can be expanded on a modular basis.
The mechanical components vary only in the X-axis, i.e. depending on the traverse path and the table variant.

Highlights

Compact milling head with 1'135 Nm torque

Continuously developed since 1982 and proven hundreds of times in use, its compact design withstands even the greatest cutting forces.

The torque is transmitted via a 2-stage ZF gearbox from the gear shaft to the spindle via a bevel gear. The milling head can be optionally equipped with SK50 BigPlus or HSK-100.

2. operating station on the rear side

In addition to the front control panel, the same control panel is optionally available at the rear. By means of the transfer key, control can be transferred to the other console at any time. This allows a perfect view of the workpiece and the tool even with the head in a horizontal position.

Electric-hydraulic beam compensation

The physically induced sag of the milling beam during extension is compensated by means of electro-hydraulically controlled mechanics. The deviation of the cutting edge can be guaranteed within +/- 0.01 mm for a travel of 1'200 mm by means of this compensation.

Cooled tours

The scraped guides of the BFR2 are deep-hole drilled in the Y-axis and are permanently flown through with cooling medium. This prevents the frictional heat of the sliding guide from having a negative influence on the accuracy of the axis. The temperature of the medium is measured with various temperature sensors and regulated accordingly.

Minimal non-productive time thanks to automation concept

Pallet changer

The flexible automation concept enables the machining of large and complex single parts during the manned shift and small and medium series during the unmanned shift. The modular design allows the machine to be expanded from the standard pallet with two tables to linear storage. The operator friendliness as well as the handling of the machine are not affected.

Energy Efficiency

Measures by our machine tools

Even in developing a machine, we look for components and elaborate solutions that make it possible to keep the consumption of expensive resources such as electricity and air in daily use as low as possible. This not only helps to protect the environment, but also minimise the daily running expenses. The most important measures to increase energy efficiency are the following:

 
  • Power regenerating drive systems
  • Chip conveyors with interval function
  • Coolant flushing with interval function
  • Automatically deactivating suction system
  • Automatic shut-down of auxiliary programs after the program cycle ends
  • Leaktight valve technology
  • Frequency-regulated coolant high-pressure pumps
  • Weight-optimised moving masses
  • Low-watt valve technology
  • Patented spindle drive concept DDT
  • Consumption-optimised pneumatic system
  • High-quality servo axes
  • Machine lighting with high-efficiency LED lights
  • Use of high-quality components with high efficiency
  • Readjusting hydraulic system (BFR2)

The use of polymer concrete as base material requires around 30% less primary energy than equivalent cast body. And even the CO2 share can be reduced by 66%. The disposal of polymer concrete, too, is uncomplicated, because as regular construction rubble it can be recycled for new filling materials or soil stabilisation.

As a producer of machines with a single production location, a high level of own production and local supplies, we are able to reduce transports to a minimum. At the same time, our machines have a long service life, which adds to the overall positive balance.
