Placement Piece

The approximate centering is obtained by means of cones to be applied on the bar while the precise centering is obtained by means of two universal centering devices with comparator. 

A bridge-shaped comparator-holder ensures perfect alignment of the bar with respect to the mono-block plane.

Head of Command

The head is mounted on a support that can be oriented both vertically and transversely, thus allowing a quick and precise alignment. 

The control elements are grouped on the head making the preparation for processing simple and practical. 

The spindle is equipped with two end stops. 

The lubrication of the head is automatic

Bar supports

The bar supports can be moved across the worktop and are vertically adjustable. 

The bar bearing bushes are adjustable with the possibility of oscillating and moving transversely to obtain a rapid alignment.
