Tos BUC63B Universal cylindrical grinding machine

Tos BUC 63B  UNIVERSAL CYLINDRICAL GRINDING MACHINE WITH ELECTRONICALLY CONTROLLED INFEED

The BUC 63 B grinding machine is designed for traverse or plunge-cut grinding of both external and internal cylindrical and conical surfaces. With the machine, face grinding can be done on the wheel side or on the wheel periphery when the workhead is swivelled.

The BUC 63 B grinding machine is mainly used in single-part and small-lot production where it allows workpieces of up to 3000 kg to be ground. The automatic working cycle can be used during grinding, and the BUC 63 B provides increased accuracy, allowing individual diameters to be ground within the IT 4 tolerance limits.
