BSB Model
ABOUT MACHINE
“BSB” model is universal cylindrical grinding machine for external and internal grinding of work parts smaller dimensions. It is suitable for flexible and mass production. The model classification is done based on distance between centers – 300 and 500 mm. Maximum swing over diameter is 270 mm, and part weight up to 25 Kg. The maximum external grinding wheel diameter is Ø400 mm, maximum internal grinding diameter is Ø80 mm, while maximum hole grinding length is 110 mm for BSB 300, i.e. 170 mm for BSB 500.
The model is available in NC and CNC option. NC option has a possibility of mounting lifting type internal grinding attachment and belt driven spindle. Basic customization is related to turret wheelhead – B-Axis, with additional equipment according to the grinding requirement, primary in one set up: external grinding, hole, face, taper, complex profiles. A combination of spindles for external and high-frequency spindles for internal grinding.
