What are the advantages of High-Precision Micro Flat Wire Rolling Mill

       The core advantages of High-Precision Micro Flat Wire Rolling Mill are concentrated in ultimate dimensional accuracy, mirror level surface, high efficiency and stability, intelligent controllability, adaptability to high-end materials and miniaturization. It is a key equipment for upgrading precision wire (copper, aluminum, precious metals, alloys, etc.) that traditional rolling mills cannot meet.

1、 Ultimate dimensional accuracy (core advantage)

       Thickness tolerance: ± 0.003 to ± 0.005 mm (3-5 microns), while conventional rolling mills only have a tolerance of ± 0.02 to ± 0.05 mm.

       Width tolerance: ± 0.008 to ± 0.01 mm, with no widening or narrowing of narrow lines.

Straightness: ≤ 0.5 mm/m, no side bending, no waves.

       Contour accuracy: regular cross-section, no collapsed edges, no burrs, suitable for precision winding and assembly.

       Control mode: dual servo closed-loop roller gap+online AGC automatic compensation+PLC real-time control, dynamic correction, no drift.

2、 Mirror level surface quality (key value)

       Surface roughness: Ra ≤ 0.8 μ m (up to Ra 0.1-0.4 μ m), close to mirror finish.

       No scratches, no pitting, no oxidation, no adhesion, suitable for post processes such as electroplating, welding, enameling, high-frequency insulation, etc.

       Roll: Hard alloy (tungsten steel)/high-speed steel+ultra precision grinding+closed-loop water cooling, low friction, long life.

       Lubrication and cooling: Special environmentally friendly medium, precise temperature control, and suppression of thermal deformation.

3、 Efficient, stable, and highly consistent (advantages of mass production)

       Speed: up to 600-650 m/min, which is 2-3 times that of a regular rolling mill.

       Continuous production: automatic roll changing, non-stop feeding, tension closed-loop (fluctuation within ± 1%).

       Batch stability: The tolerance of the entire roll/batch is consistent, and the defect rate is less than 0.5%.

       Multi pass continuous rolling: one-time forming, reducing intermediate annealing, and increasing yield by 15% to 25%.

4、 Wide compatibility of materials and specifications (flexible production)

Rolleable material:

       Copper and copper alloys (purple copper, brass, bronze, white copper, copper nickel silicon)

Aluminum and aluminum alloys (1000/3000/6000 series)

       Precious metals (gold, silver, platinum, palladium), stainless steel, nickel titanium alloys, constantan, manganese copper, etc

Specification range:

       Thickness: 0.05-2.0mm (mainly micro ultra-thin)

       Width: 0.5-20 mm (narrowband/micro flat wire)

       Can be made in square, trapezoidal, wedge-shaped, hourglass shaped, and irregular cross-sections.

5、 Intelligence and automation (cost reduction and efficiency improvement)

       Full process PLC+servo control: parameter storage, one click changeover, fault self diagnosis.

       Online detection: laser thickness/width/contour measurement, out of tolerance alarm, automatic compensation.

       Data traceability: production records, quality reports, compliance with IATF16949/pharmaceutical/aviation standards.

       Low energy consumption, low noise, environmentally friendly lubrication.
