Fly Shears For Cutting Strip At Full Line Speed
Shears that cut while the strip keeps moving, so the line never decelerates for a crop.
A stop and cut shear caps line speed, wastes yield at every crop and marks the strip through repeated starts and stops.
Fly Shears We Supply
Rotary and servo driven configurations for pickling, galvanizing, slitting and cut to length lines.
High Speed Fly Shear for Continuous Strip Cutting
Rotary fly shear cutting at line speed, up to 2500 strokes per minute with carbide tipped blades.

View DetailsWho Buys Fly Shears
Who fits a fly shear.
- Rolling mills whose shear is the speed bottleneck
- Service centres cutting sheets to preset length
- Plants moving to thinner gauges at higher speed
- Project teams modernising an older cutting section
- Line speed capped by stop and cut shearing
- Yield lost at every deceleration and restart
- Surface marks and warping from static shearing
- Blade wear at high cutting frequency
Why Plants Source Fly Shears From Ascon
Performance you can measure.
2500 Strokes Per Minute
Maximum cutting frequency of 2500 strokes per minute with micron level accuracy and no strip warping.
40 Percent More Output
Output rises around 40 percent against a hydraulic static shear because the line never stops for a cut.
Lower Energy Per Tonne
The energy efficient drive cuts power consumption by around 30 percent compared with conventional hydraulic shearing.
Application Scenarios
Where they are used.
Head And Tail Cropping
Cropping moving strip in continuous rolling lines without deceleration.
Cut To Length Production
Cutting sheets of preset length on the fly with closed loop length control.
Multi Material Processing
Carbon steel, stainless steel, aluminium and titanium alloy strip with blades matched per material.
Fly Shears Buying Questions
How does a fly shear hold length accuracy at speed?
A length measuring encoder feeds a PLC motion controller and servo drive, with closed loop feedback on shear position and speed.
Which materials can it cut?
Carbon steel, stainless steel, aluminium and titanium alloy, with blade specification matched to the material.
What blade life can we expect?
Carbide tipped blades give around 50 percent longer service life with 60 percent lower friction than the standard blade they replace. Actual life depends on gauge and cut frequency.
Can it be retrofitted?
Yes, subject to space and the automation interface. Send the line layout, speed, gauge range and PLC type.
How much output will we gain?
Around 40 percent against a hydraulic static shear, because the line no longer decelerates and restarts for each cut.
What do you need to quote?
Material and gauge range, width, line speed, required cut lengths and your control system.
