BUC E

BUC E is a fully CNC controlled grinding machine designed for longitudinal 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 face surfaces can be performed by the side of grinding wheel or its circumferential surface using grinding wheelhead swivel.
