If you’re seeking high-performance, reliable cross-cutting lines or cut-to-length machines for metal coil processing, Tengdi Machinery is your trusted partner. As a professional manufacturer of cross-cutting production lines and cut-to-length equipment, we offer a diverse range of solutions tailored to meet your unique production requirements—ensuring you get the most suitable cutting line for your workflow.

Backed by a team of skilled experts with years of industry experience, Tengdi guarantees top-tier quality in every piece of equipment. Our cross-cutting lines stand out in the shearing equipment field, with two core advantages: exceptional cutting precision (up to ±0.15mm) and high cutting speed (up to 100m/min). These features not only boost production efficiency significantly but also ensure consistent shearing quality, making our equipment widely used in key manufacturing industries such as automobile manufacturing, home appliances, hardware, and metallurgy.

In addition to cross-cutting lines, we also provide cut-to-length machines (also known as cut-to-length lines)—integrated systems designed for uncoiling, leveling, and cutting metal coils into flat sheets of specified lengths, followed by stacking. These machines handle a variety of metal materials, including cold-rolled steel, hot-rolled steel, galvanized steel, silicon steel, stainless steel, and aluminum coils, and can be adjusted to process different widths based on user demands.

A cut-to-length machine (or cut-to-length line) is a specialized metal processing equipment that performs three key tasks: uncoiling metal coils, leveling the uncoiled sheet (to eliminate warping), and cutting the sheet into flat pieces of the required length—finally stacking the finished sheets neatly. It is a critical piece of equipment for converting continuous metal coils into usable flat materials for downstream production.

The cut-to-length machine processes strip steel coils into specified steel plates through a systematic workflow, supported by a complete set of components:

• Key Core Components: Uncoiler (for unrolling coils), pincher & leveler (for flattening sheets), gauge (for width adjustment), cutting machine (for length cutting), stacker (for neat sheet stacking).
• Auxiliary Components: Feeder (for stable material conveying), side guiding device (for preventing sheet offset), transition mechanism, and conveyor (for transferring materials between stations).

Together, these components ensure smooth, automated processing—from coil input to finished sheet output—reducing manual intervention and improving consistency.

Tengdi’s cut-to-length machines are classified based on two key criteria to meet diverse application needs:

• By Metal Material:
  • Stainless steel cut-to-length machine
  • Silicon steel cut-to-length machine
  • Cold/hot-rolled plate cut-to-length machine
• By Electronic Control Mode:
  • Pneumatic cut-to-length line (suitable for medium-precision, cost-effective scenarios)
  • NC (Numerical Control) cut-to-length line (for high-precision, automated production demands)

Below are the comprehensive technical specifications of Tengdi’s cut-to-length machine models, covering thickness range, width range, cutting precision, and more:

The cut-to-length machine follows a standardized, automated workflow to ensure efficient, precise processing of metal coils. The step-by-step process is as follows:

1. Coil Lifter: Lifts and transfers metal coils to the hydraulic decoiler, ensuring safe, stable coil loading.
2. Hydraulic Decoiler: Unrolls the metal coil at a controlled speed, matching the subsequent processing pace to avoid material slack or tension.
3. Snubber Roller: Stabilizes the uncoiled sheet, preventing vibration or offset during conveying.
4. Pinch Roll & Pre-Leveler: Pinches the sheet to maintain tension and performs preliminary leveling to reduce major warping.
5. Loop Bridge: Stores a small amount of sheet material to buffer the speed difference between decoiling and leveling, ensuring continuous production.
6. Side Guide Roller: Guides the sheet to stay centered, avoiding lateral offset that affects cutting precision.
7. Main Leveling Machine: Conducts fine leveling to eliminate residual stress and warping, ensuring the sheet is flat for cutting.
8. Encode & Measuring Device (with Tail Plate Pinching): Accurately measures the sheet length using an encoder; the tail plate pinching function secures the sheet end during cutting.
9. Shear: Cuts the sheet into the specified length with high precision, matching the model’s cutting accuracy standards.
10. Conveyor: Transfers the cut flat sheet to the hydraulic lift platform.
11. Hydraulic Lift Platform: Adjusts the height of the sheet to align with the stacker, facilitating neat stacking.
12. Stacker with Blower Device: Stacks the sheets neatly; the blower device removes dust or debris from the sheet surface to ensure cleanliness.
13. Unload Cart: Transports the stacked finished sheets to the storage area or next production link.
