Kinematic Superiority
Synchronous Dynamic Cross-Cutting Engineering
Unlike conventional Start-Stop Cut-to-Length (CTL) lines where strip inertia must be repeatedly halted via pinch-roll friction—generating surface scuff marks, roll slip, and severe mechanical vibration—a Flying Shear Production Line operates on continuous kinematics. The shearing die accelerates dynamically to synchronize precisely with the traveling web, executes the cut at zero relative velocity ($\Delta v = 0$), and returns to the initial position in an electronically regulated cam cycle.
By eradicating the acceleration-deceleration cycle of master coils weighing upwards of 35 metric tons, a flying shear maximizes duty cycle uptime, lowers thermal and mechanical stress on electrical drive trains, and boosts net linear sheet output by up to 280% compared to traditional stationary shear operations.
- Zero Surface Friction Marks: Eliminates strip slippage against leveling rollers during cross-cut phases, safeguarding auto-exposed Class A finishes.
- Electronic Cam Profile (E-Cam): Real-time trajectory compensation adjustments driven by high-speed FPGA DSP controllers.
- Ultra-Low Blade Clearence Deviation: Pre-stressed linear guide rails maintain lateral blade clearance under ±0.015mm across entire cross sections.
Dynamic Servo-Drive Kinetic Loop
Our line integrates regenerative AC synchronous servo motors capable of delivering instant acceleration spikes exceeding 12m/s². In conjunction with high-resolution absolute encoders (up to 24-bit feedback), the dynamic control algorithm continuously reconciles material stretch, roll slip, and thermal elongation on the fly.

Global Industry Panorama
Macro-Economics & Global Commercial Realities
Strategic shift in global coil distribution: How modern metallurgy is demanding tighter tolerances, reduced inventory carrying cycles, and accelerated processing speeds.
Pressure on Metal Service Center Margins
Across Europe, North America, and emerging markets, metal service centers face margin compression caused by fluctuating raw steel spot prices and rising labor expenditures. Standard stationary CTL equipment acts as a throughput bottleneck, requiring operators to run second and third shifts to meet delivery windows.
Transitioning to synchronized flying shear solutions enables processors to triple their daily tonnage processing envelope using the identical shop footprint and crane capacity, slashing unit transformation cost ($/ton) by over 40%.
Evolution Toward Advanced High-Strength Steels (AHSS)
The automotive and clean-energy sectors have adopted ultra-high yield strength materials exceeding 780 to 1180 MPa. These alloys possess severe residual springback and intense cutting resistance that trigger rapid fatigue fractures on conventional stationary blade mounts.
Modern Jianfa flying shears feature heavy ductile cast bases, spherical roller bearings with high dynamic load ratings, and proprietary hydraulic dampening manifolds designed specifically to handle extreme yield steels without chatter or blade chipping.

Industrial Q&A
Technical & Commercial FAQ: Flying Shear Lines
Direct engineering responses to key questions asked by manufacturing plant directors, engineering consultants, and procurement managers.
What is the core kinematic difference between a Flying Shear and a Stop-and-Go Cut-to-Length line? +
A conventional stationary Cut-to-Length line forces the feeding strip to accelerate from zero velocity, stop entirely during the mechanical shearing stroke, and accelerate back up. This intermittent duty cycle imposes severe dynamic shock on the uncoiler, induces friction scratches on delicate surfaces via roll slip, and restricts output speeds to roughly 30–40m/min. In contrast, a Flying Shear line accelerates the shear carriage synchronously to match strip velocity perfectly. The cut occurs while the strip travels continuously at up to 100–120m/min, eliminating inertia shock, surface roll marks, and vastly boosting overall line yield.
What thickness and width range can Jianfa Flying Shear Production Lines accommodate? +
Wuxi Jianfa engineers custom flying shear solutions covering strip thicknesses from 0.3mm to 16.0mm and coil widths up to 2200mm. For lighter gauges (0.3–3.0mm) demanding exceptional production rates, our high-speed rotary flying shear provides maximum cuts per minute. For medium to heavy plate applications (3.0–16.0mm), our reciprocating oscillating moving shear systems provide massive structural rigidity and high shear forces required for high-yield hot rolled coils.
How does the system maintain ultra-tight length tolerances at fluctuating line speeds? +
Length precision (±0.2mm to ±0.5mm depending on gauge) is achieved via high-precision closed-loop electronic camming. High-frequency digital surface wheel encoders monitor linear web movement independently of drive roll slip. The master PLC / motion controller processes this position data in microsecond cycles, dynamic adjusting the servo motor velocity profile so the flying shear reaches exact linear synchronization with the predetermined cutting plane.
Can the leveling unit in a flying shear line handle high-yield steels such as S700MC or Hardox? +
Yes. We engineer specialized 4-Hi and 6-Hi high-strength leveling machines equipped with heavy-duty backup rolls, high-rigidity structural frame weldments, and multi-point hydraulic roll crown adjustment. These units deliver the plastic deformation ratios (typically over 75% outer fiber yield) necessary to completely eradicate residual internal stress and eliminate coil memory in ultra-high yield strength steels.
What factory preparation and utility supplies are required prior to line delivery? +
Upon project sign-off, Jianfa provides precise civil foundation blueprints detailing foundation pits, anchor bolt positions, hydraulic conduit trenches, and drainage sumps. Utility requirements generally entail a stable 3-phase industrial power supply (voltage customized to your national grid), clean compressed dry air (0.6–0.8 MPa), and standard industrial cooling water loops for hydraulic fluid heat exchangers.
What quality inspection and factory acceptance testing (FAT) occurs before shipment? +
Every machine is fully erected, mechanically connected, and wired in our Wuxi assembly workshop for comprehensive no-load and full-load running tests. Buyers are encouraged to attend FAT either on-site at our 40,000 m² factory or via real-time high-definition video inspection, verifying precision blade clearances, electronic synchronization, emergency stop responses, and dimensional accuracy on sample coils before sea-freight packing.
