BK-H series Our objective: Creating the economic surplus in your daily manufacturing life precision BK 100 H for small and medium workpieces up to 100 mm in dia. 2 B&K H-series BK 200 H for long and heavy workpieces up to 200 mm in dia., different length versions available

The BK-H series of horizontal hobbing machines for the economic manufacturing of gears and shafts – now for workpieces up to 600 mm in diameter and module 25 .0 We craft each and every machine with a wide range of options to suit your individual needs, guaranteeing you the efcient manufacturing of top quality workpieces. This versatile horizontal series is ideally suited to hob and mill geared workpieces, especially a wide array of small, medium sized and very long and heavy geared shafts. For larger workpiece lots you can equip the BK-H with either a driven chain loader or a portal loader...

The small footprint horizontal hobbing machine for shafts and gears, up to 127 mm in diameter and module 2.54 The BK 100 H is the smallest version of the H series machines. Its compact design leaves you with minimum space requirements to worry about. The simple construction features no hydraulics with only a limited number of wear parts. The machine cuts external spur and helical gears as well as crown gears. It is especially suited for splines and geared shafts up to 100 mm in diameter. 4 B&K H-series BK 100 H Especially advantageous is the possibility to mount tool combinations to cut...
