HYDRAULIC REAR SHEET SUPPORT
The sheet support is an hydraulic device placed behind the shear to hold the sheet before the cutting operation. It's suggested for cutting sheet of small thick and large width. This device avoids mistakes due to the fall-down of sheet and allows to keep the pre-set measure.
Our rear sheet support has besides a first stop at the middle of the stroke to avoid the sliding of sheet under the hold down pistons.
This equipment is integrated with the cutting cycle and grants a simply and profitable use; its switching off is possible by a push-button on the control panel.

POWERED BLADE GAP ADJUSTMENT
The blade gap and the cutting angle are two devices that optimize the cutting operation. A right use of these two devices grants to carry out cuts without burr and bending.
All our standard GHB shears have the manual adjustment of blade gap. This adjustment is carried out by two levers sliding on the graduated scale. As optional is possible have a powered blade gap adjustment managed by six push-buttons on the control panel.

CUTTING STROKE DEVICE
The cutting stroke device allows to stop the upper blade at a pre-set point of stroke. This device allows to save time during the production cycle.

BACK GAUGE
The back gauge of GHB shears can be supplied with some optionals:
- Stroke 1000 mm. instead of standard stroke of 700 mm. for deeper cutting.
- Recirculating ball screws instead of standard cold-formed ones. This improves cutting accuracy.
- Tilting back gauge. This device allows to make cuttings deeper than ones allow by the back gauge stroke. The tilting can be coupled only with back gauge stroke of 1000 mm. The tilting starts after the back stop has made a stroke of about 850 mm.

OTHER OPTIONAL
Standard GHB shears are equipped with millimeter squaring arm and two front supports on which is possible put the following fittings:
- Sliding balls
- Front micrometrical adjustment
- Disappearing fingers
- Goniometer for oblique cuttings
To make easy the production cycle is possible to equip the machine with the following devices:
- Shadow line lighting : This device threw a light beam on the sheet and a wire placed between the sheet and the light source creates a shadow on the cutting line.
- Sheet chute.
