Biglia B446 - T2 B465


The range of QUATTRO machines have been produced by Biglia since 1990 and celebrating the third generation is now further enhanced by the B436Y2 model. This new model is launched to meet with the specific market requirements for bar machining in automatic turning: a twin-turret and twin-spindle CNC-lathe with fixed headstock, compact, versatile and quick for combined turning, milling and drilling of small-sized parts. The B436Y2 has a very compact structure offering optimum use of available space in the workshop (less than 5 sqm). The sturdy cast-iron construction, the robust components such as the main bed, linear rails, turrets and spindles combined with powerful spindle motors (11 kW) and live tools (max. 4.6 kW) will allow you to achieve significant results: - optimal machining of all materials, especially tough alloys - reduction of cycle times and longer tool service life - perfect and efficient method of ‘Chip’ removal - ergonomics and easy access for setup and retooling operations.
