Universal grinding machine BUB E 32/40/50 CNC
 

BUB E CNC is fully CNC controlled grinding machine designed for traverse and plunge-cut grinding of cylindrical and conical external surfaces, or with internal grinding attachment for grinding of cylindrical and conical internal surfaces. Grinding of surfaces can be performed by the side of grinding wheel or its circumferential surface with using work head swivel. Grinding machine series BUB E can be used particularly in series and large series production for grinding of workpieces up to 500 kg. The machine is made in the high accuracy and enable grinding of single diameters in the tolerance of IT 4 and higher. Standard version of the machine is equipped with control system Siemens 802D sl, alternatively Siemens 840D sl or B&R.
