What This Machine Does
The QC12Y is a hydraulic swing beam shearing machine, the standard cutting tool under most sheet metal departments. The model designation says exactly what the machine does: in QC12Y-6X3200, QC12Y is the hydraulic swing beam type, 6 is the maximum cutting thickness in mild carbon steel plate in millimetres and 3200 is the maximum cutting width in millimetres. In a swing beam design the upper blade beam pivots through an arc rather than travelling straight down, which keeps the mechanism simple and the machine easy to maintain compared with a guillotine-action shear. The QC12Y and the related QC11Y cover 6mm, 8mm and 12mm cutting thicknesses. Machines of this type are used across industrial machinery, metallurgy, automotive, shipbuilding, electrical appliances, engineering equipment, sheet metal processing, steel pipe welding, electronics, aerospace, agricultural machinery and furniture manufacture.
Why Buyers Choose This Machine
- Swing beam mechanism is simpler to maintain than a guillotine-action blade carriage
- Model designation states cutting thickness and width so the machine is easy to specify
- 6mm 8mm and 12mm thickness options across the QC12Y and QC11Y range
- 3200mm cutting width on the QC12Y-6X3200 takes full standard plate in one cut
- Hydraulic drive keeps cutting force steady through the full stroke on thick plate
- Suits a wide industrial range from shipbuilding and metallurgy to appliance manufacture
Where QC12Y Large Hydraulic Swing Beam Shear Earns Its Place
Problems It Solves
- Thermal cutting of straight blanks leaves a heat affected edge that has to be dressed
- Small shears force wide plate to be cut in two passes with a mismatch at the join
- Mechanical shears lose cutting force through the stroke on thicker plate
- Complex blade carriage mechanisms are slow to maintain in a busy plate shop
- Choosing a shear is guesswork when thickness and width are not stated in the model
Who It Is For
- Heavy fabrication and structural steel shops cutting plate to 12mm
- Shipbuilding automotive and agricultural machinery manufacturers
- Steel service centres cutting plate to size
- Machinery distributors supplying hydraulic shears to plate fabricators
Application Scenarios
- Cutting carbon steel plate blanks in a heavy fabrication shop
- Plate preparation for steel pipe welding lines
- Blanking for automotive shipbuilding and agricultural machinery manufacture
- Cut to size work in metallurgical and steel service operations
- Producing plate blanks for engineering equipment and appliance production

How It Compares With the Alternatives
| QC11K CNC hydraulic guillotine shear | The QC11K guillotine action with CNC back gauge and adjustable shear angle is the choice for tight repeat accuracy; the QC12Y swing beam is simpler and suits general plate cutting |
|---|---|
| Plasma or oxy-fuel cutting | Thermal cutting handles shapes a shear cannot, but on straight blanks it is slower and leaves a heat affected edge; the QC12Y shears a clean edge in one stroke |
| Mechanical shearing machine | A mechanical shear relies on flywheel energy that falls away through the cut; hydraulic drive holds force through the full stroke on thicker plate |
Running the Machine
Step 1
Confirm the plate grade thickness and width are within the machine rating
Step 2
Set the blade clearance for the plate thickness being cut
Step 3
Set the back gauge for the blank width and check it on a first piece
Step 4
Support long plate on the feed and run-off side so it does not drop during the cut
Step 5
Shear a first piece and measure it before running the batch
Step 6
Keep hands and tools clear of the beam area and keep guards in place
Step 7
Check the blade edges for burring and index or regrind when the cut quality drops

Questions About QC12Y Large Hydraulic Swing Beam Shear
What does QC12Y-6X3200 mean?
QC12Y is the hydraulic swing beam shearing machine type, 6 is the maximum cutting thickness in mild carbon steel in millimetres and 3200 is the maximum cutting width in millimetres.
What thicknesses are available?
The QC12Y and QC11Y range covers 6mm, 8mm and 12mm cutting thickness. Send us your heaviest plate and widest sheet and we will recommend the model.
What is the difference between swing beam and guillotine shears?
In a swing beam machine the upper beam pivots through an arc, which keeps the mechanism simple. A guillotine-action machine such as the QC11K moves the blade in a controlled path and offers adjustable shear angle for tighter accuracy.
Can it cut stainless steel?
Ratings are given for mild carbon steel. Stainless steel reduces the usable thickness, so send us the grade and thickness you cut and we will confirm which model suits.
What supply voltage is the machine built for?
Tell us your voltage, phases and frequency with the order and the machine will be wired and tested to that supply.
How is the machine shipped?
It is a heavy machine shipped in export packing from Xi'an. Send us your destination port and we will quote FOB CFR or CIF with the shipping dimensions.
What are your payment terms?
30 percent by T/T on order and 70 percent before shipment, or an irrevocable L/C at sight.
