Durma Variable Rake Guillotine

Durma VS Series

The standard features allow the adjustment of a great variety of parameters that influence the cut quality, namely rigidity, rake angle, blade clearance etc. On the CNC-HGM model the blade gap clearance, rake angle, cutting length and backgauge positioning are automatically adjusted after programming the DNC with the data of the plate to be cut.

The deep throat allows for the cutting of sheet plates longer than the blade length. The backgauge has a retract movement for a slight swing during the cut, helping the cut-off strips fall down and therefore preventing the strips becoming jammed between the backgauge and the fixed blade.

Variable Rake

The possibility of changing the rake angle (either increase or reduce) depending on different plate thickness ensures a better cutting performance with minimum strip deformation. The position of the rake angle is set by means of an electronic control, by setting the thickness to be cut, the ram goes automatically into position and chooses the ideal cutting angle.

Finger Guard, Ball Transfers & Holddowns
The first one meter of the finger guard can be flipped up out of the way for easy viewing of the work piece at the cut point. Holddowns are provided to ensure that the plate is held firmly along the length of the cutting area.

Back Gauge
The backgauge adjustment, standard range 1000mm, has play free straight guides and re-circulating ball spindles; it has speed of 200mm/sec, a setting accuracy of 0.1mm and a repetitive accuracy of +/- 0.1mm.
