Product Characteristics
The High Precision Straightener is a high-performance coil leveling machine designed for manufacturers processing ultra-thin and high-precision metal materials. It is specifically engineered to remove residual stress, eliminate coil set, and achieve exceptional flatness before stamping, laser cutting, or precision forming operations.
Unlike conventional straightening machines, this model features precision-engineered leveling rollers, a rigid transmission system, and micron-level adjustment capability to ensure stable and repeatable results. It is particularly suitable for processing stainless steel, copper, aluminum, nickel, and other thin metal coils with thicknesses starting from 0.1 mm.
Widely used in electronics, semiconductor components, EV battery parts, precision hardware, medical devices, and connector manufacturing, the Ultra Precision Straightener helps improve stamping accuracy, extend die life, reduce material waste, and enhance overall production efficiency.
Engineered specifically for stamping medium-thin materials requiring micron-level accuracy. Coil materials must undergo stress-relieving leveling to ensure production quality, making the leveler's performance pivotal in manufacturing excellence.
Optimized for flawlessly leveling ultra-thin sheets (stainless steel, copper, iron, and aluminum) with thicknesses as low as 0.1mm, delivering unmatched surface flatness.
All leveling rollers utilize imported SUJ2 steel, heat-treated to HRC 60°, followed by hard chrome plating and precision grinding to guarantee uniform coating (±0.001mm) and cylindrical tolerance (±0.003mm).
Equipped with a floating four-point micro-adjustment mechanism and integrated dial indicator, enabling rapid calibration for immediate precision alignment.
Dual fully-driven upper/lower rollers eliminate energy waste and surface abrasion caused by passive rotation in conventional systems, ensuring 100% material integrity.
Advanced auto-lubrication system minimizes wear, extending operational lifespan while maintaining sub-10μm precision over continuous 24/7 runs.
Optional flip-top head design allows instant access to rollers for debris removal, streamlining cleaning without disassembly.
Ultra-thin metal coils often contain internal stress, coil memory, edge waves, center buckles, and other flatness defects generated during rolling and storage. If these imperfections are not removed before stamping or forming, they may lead to:
Poor stamping accuracy
Material deformation
Burr formation
Die wear
Feeding instability
Low product consistency
Increased scrap rates
A high-precision straightener effectively relieves internal stress and restores material flatness, ensuring stable feeding and superior product quality throughout the production process.
In the 3C electronics manufacturing industry, components such as smartphone and tablet parts require extremely high flatness, dimensional accuracy, and surface quality.
