Design features


The machine bed is made of high rigidity thermal-treated steel to provide maximum strength of the structure. The wheelhead is equipped with a specifically designed electrospindle that is dynamically balanced and fixed on precision bearings.

Wheelhead orientation regulating device

A specific device  is designed to regulate the orientation and allows maintaining constant perpendicularity between the axis of the grinding wheel and the work table, which makes the geometrical trim of the machine easily adjustable to changed settings.

Feed on handwheel

Quick vertical feed on handwheel is provided by a drive that gives it a move up or down 2 mm per one turn of the handle. Micrometric feed is provided through a coupled ratchet.

Electrical system

All machines are equipped with safe electrical systems with low voltage controls (24 V).

European quality standards
