With its sophisticated and streamlined design, CORVUS BBA has become the leading grinding machine for broaching tools of all configurations. It is the result of many years of collaboration between renowned broach manufacturer K. HOFFMANN GmbH (Pforzheim Germany) and J. SCHNEEBERGER Maschinen AG.For flat, cylindrical or helical tools, the machine kinematics and powerful software provides the end-user a highly efficient system for mastering a full range of grinding requirements.

CORVUS BBA is available in three X-axis travel lengths:1100 mm (43.30”), 1700 mm (66.50”) und 3000 mm (118”).

– diversified application range

– continuous precision

– rapid stock removal rate

– speed and rigidity

– long service life

For broach grinding

Flexibility and Precision

Smart grinding headWith the programmable B and C axes, CORVUS BBA can meet the challenges of the most complex geometries – with the accuracy one has grown to expect from SCHNEEBERGER.

Optimum kinematics and superior machine construction are the fundamentals of enduringly

accurate grinding results within the tightest tolerances.When it’s a question of high stock removal rates, the

machine is uniquely suited to face the challenge with its water-cooled 9 kW (13 HP), direct-drive spindle motor.

Programming technology

QUINTOThe SCHNEEBERGER grinding software

Our many years of experience in tool grinding providedthe core values for the creation of QUINTO – a namewidely recognized in the tool grinding industry for its easyto understand, user-friendly interface. One remarkable feature of QUINTO is its windows menu, guiding the userthrough the programming of the most complex tools.New applications are easily integrated into the program.For grinding broaches, the geometry data is either readilyavailable in the program library, or is quickly and accu-rately determined by the measuring probe, guaranteeingthe ability to grind within minutes.
