Introduction: Why the Shearing Mechanism Matters in High-Speed CTL Lines
In each rotary shear cut to length line, the shearing system is always the heart of the cutting process. It determines not only how clean and accurate your metal sheets are, but also the speed, reliability, and wear-resistance of the entire life.
At Kinbenz, our hydraulic shear is specifically engineered for multi-thickness steel, copper, and aluminum coil processing, integrating high-speed servo response with smart automation.

What Makes the Cutting Quality Superior?
A. Bottom-Up Cutting with Burr Facing Up
Unlike traditional top-down shearing, our hydraulic shear cuts from the bottom to the top. This innovative approach pushes any burrs upward, preventing direct contact between rough edges and the material conveyor belt:
- Extends conveyor lifespan
- Reduces surface scratches
- Improves overall downstream material handling safety
B. Servo-Controlled Blade Gap Adjustment
When switching between materials of different thickness, the gap between the rotary shear blades must be finely tuned. Our system uses a servo motor and HMI interface to allow:
- Real-time, tool-free gap adjustment
- Minimization of burrs and warping
- Faster material changeovers without manual recalibration
C. Hydraulic Power for High-Speed Output
Powered by a hydraulic motor, the cutting crankshaft delivers powerful, stable shearing motion - ideal for processing coils at high speed ( Up to 80m/min or more depending on the line configuration). Combined with a robust frame, the system ensures:
- Stable shearing under high tonnage
- Accurate sheet length maintenance
- Long-lasting, low-maintenance operation
Blade Type: Four-Sided Design
The cutting blade is four-sided, meaning it can be rotated up to four times before replacement - dramatically reducing downtime and part cost. This ensures:
- Lower maintenance frequency
- Minimal line interruption
- Consistent cut quality over months of production
FAQ:
Q: Can the shear handle both thin and thick coils?
A: Yes, our standrad rotary shear cut to length line solution it's suitable for 0.3mm-3.0mm thickness range. But we also offer customzied machine solutions to match your actual requirements.
Q: What maintenance is needed for the hydraulic shear?
A: Thanks to its centralized lubrication system and four-sided blade design, routine checks and periodic blade rotating are sufficient for most users.
