Metal cutting guillotines for the cutting/shearing of sheet metal, or steel plates.
When choosing a metal cutting guillotine,
There are a variety of factors that will influence your selection of a metal cutting shear, such as :
Hydraulic metal cutting shears are used for heavy duty metal fabrication work,
ie sheet materials above 4/6mm thick upto approx 25mm
Hydraulic heavy duty metal cutting guillotines are slower in strokes per minute than a mechanical sheet material guillotine, but generally offer features of value, such as : longer length stroke back gauges, variable cutting rake angles, stroke length limitation.
Mechanical direct drive (DD) guillotines tend to be used for lighter sheet metal working.
Thickness capacities in the order of 1mm to 4mm, with strokes per minute upwards of 30spm. power back gauge with digital readout, pneumatic sheet support systems, are generally viewed as a desirable options.
‘Swing Beam’ Guillotine :
Offers a fixed cutting rake angle, the fabricated top blade carrying structure is mounted to the rear of the machines side frames,
into eccentric bearings, it is the rotation of the eccentric bearing(s) done via a handle on the side of the machine, that moves the fabricated top shear beam forward or back to create the blade gap.
The fixed rake angle differs between manufacturers, a rake angle under 3° degrees is preferable to avoid excessive curl of the cut piece,
high cutting rake angles of 3° to 4° may result in excessive curl to the cut piece. High rake angles [+3°] indicating lightly built machines, the flatter the rake angle, the more frame rigidity required.
‘Variable Rake’ Guillotine
The top blade carrying beam is attached to 2 hydraulic cylinders, by varying the stroke of each of the 2 hydraulic cylinders the top blade beam
is inclined creating the rake angle. this ability to change cutting rake angles assist in the reduction of curl in the cut piece.
‘Guided Frame’ Guillotine
The top cutting beam is held at each end in vertical slides, therefore the cutting action is vertical, the cutting beam has a fixed cutting rake angle. This system is used in all direct drive mechanical steel cutting guillotines.
Touch & Go Back gauge, type in dimension press go button, backgauge finds position, or a NC control, offering cutting programs, cut counter etc.

If cutting thin materials, thin sheets bend and dip below the backgauge system.

The chosen cutting blades of a steel cutting guillotine need consideration. Is the steel you are cutting carbon or stainless steel. Note: *Manufacturers will fit as standard metal cutting guillotine blades for carbon steel cutting. These blades are very hard and produced to predominately give wear resistance, however because of their hardness, they are likely to chip if used for cutting steels with the higher tensile strengths, like stainless steel.
