FEATURES Rapid blade gap
adjustment lever
Frame and Bed

Welded all-steel frame provides maximum rígidity and cutting accuracy. Gap in frame depending on model. Recessed table with filler plates provides easy access to manípulate and handle sheets.
Cutter Beam

The swíng frame design of the cutter beam tracks the upper blade past the stationary lower blade along an arc producíng a clean
burr-free cut surface, perpendicular to the plane of the sheet.
Due to the curved path of the cutter beam, the upper blade moves away from the lower blade duríng the cut, reducíng blade wear and increasing blade life.
The backgauge, whích is fitted to the cutter beam, also swíngs back
along an arc providing automatic cIearance between the cut
materíal and the backgauge.

Over-dimensioned, high precision, roller bearings at the swíng beam
pivots support the cutter beam precísely and elimínate fríctíon. These
self-alígning, sealed bearings provide a maíntenance-free operatíng
life as compared with traditional shear constructíon, whose vertícal
ram travellíng ín guídeways, requires both contínuous lubrication and
gib alignment. A simple lever rapidly adjusts the blade gap by displacing the axis of rotation of the cutter beam via an eccentric bushing whích houses the swing beam pivot bearings. The swing beam design utilizes low fixed rake angles to reduce cut dístortíon.
lnfinitely variable stroke length adjustment aíds productívíty by increasing the number of strokes per minute as stroke length decreases.

Shear Blades Profíle of model wíth gap
HCHC blades are supplíed. The lower shear blade has four cutting edges; the upper blade has two cutting edges.
Fíne adjustment system for blade truing.
Holddowns

lndependent hydraulic holddowns secure the plate to the table.
Standard Gauges
PROGRAMMABLE NC front operated power backgauge wíth dígital inch/metric display. Manual or automatic positioning. Stroke counter.
Automatic positioníng of gauge to any of 10 programmable positíons.
Gauge always approaches posítion from the same dírectíon to elíminate backlash.

T-slotted side squaring arm with scale and stop.
Two front support arms.
Shadow light for cuttíng to scribed 1ine.
Fínger Guards
See through finger guards protect the operator and permit a clear
víew of the blades and holddowns.

Standard Equipment for a11 models Optional Equipment
PROGRAMMABLE NC Backgauge, lnch/Metric switchable, Large throat gap
can be programmed with the size and quantity of cuts of up to Backgauge: Travel extended to 48 or longer
10 different parts. Each part size in memory has an associated CNC gauge
count down cut counter that is programmed to a maximum of Ba11 transfers
99 cuts per size. The control counts down to zero from the Holddown pads
pre-set quantity and then automatically positions the gauge Ang1e gauge
bar to the next part size. In this way, the control cycles squaring arms 48, 
through each of the 10 part sizes allowing for a maximum of
10 parts x 99 cuts/part or 990 parts to be programmed. The control can be set to automatically repeat the program at its end. Display resolution is inch / mm.
Backgauge bar lifts up automatically at the end of its travel allowing for the entry of plates into the shear which are longer than the backgauge bar travel.
