SFL Type precision straightener (Thickness: 0.2-1.2mm)

Precision Straightener Key Features

SFL Type Precision Straightener (0.2–1.2mm Thickness)

The SFL Type Precision Straightener is specially engineered for high-precision leveling of thin metal sheets, including stainless steel, copper, iron, aluminum, and other non-ferrous materials. It is widely used in industries requiring strict flatness control for thin-sheet processing.

During coil uncoiling or sheet handling, thin materials often develop curvature, wave deformation, or residual internal stress. This precision straightening machine effectively eliminates these defects, ensuring consistently flat and stress-relieved sheets before downstream processes.

High-Precision Leveling Rollers

All leveling rollers are manufactured from imported SUJ2 bearing steel, heat-treated to HRC 60, then hard chrome plated and precision ground. This process ensures:

Uniform hard chrome thickness

Excellent wear resistance

Strict cylindricity tolerance for each roller

These features guarantee stable leveling accuracy and long-term performance.

Floating Four-Point Fine Adjustment System

The SFL precision straightener adopts a floating four-point balance fine-tuning mechanism, equipped with a dial indicator. Operators can quickly and accurately locate the optimal leveling position, improving setup efficiency and repeatability for different materials and thicknesses.

Reinforced Leveling Structure

In addition to the standard upper and lower leveling rollers, auxiliary support rollers are installed inside the machine. These auxiliary rollers:

Prevent excessive pressure and bending of the main leveling rollers

Enhance overall leveling force

Extend the service life of the rollers

Improve surface flatness and dimensional stability of thin sheets

Full-Drive Roller Design

Both upper and lower rollers are fully driven, eliminating the drawbacks of passive roller transmission found in conventional straighteners. This design:

Reduces power loss

Prevents surface scratches

Ensures smooth and stable material feeding

Integrated Lubrication System

The built-in lubrication system reduces friction, minimizes wear, and maintains the machine in a high-precision working state over long production cycles, significantly extending the service life of key components.

Application Case: Automatic Coil Feeding Line for Thin Materials

In a precision electronics stamping production line, the SFL Type Precision Straightener is integrated with an automatic uncoiler and a servo feeder to form a fully automated coil handling and feeding system. This setup is used to process thin stainless steel and copper coils with thicknesses ranging from 0.2mm to 1.2mm.
The automatic uncoiler ensures smooth and safe coil unwinding, while the SFL straightener delivers excellent leveling performance. The high-speed servo feeder provides accurate and stable material feeding into the press.
This complete solution greatly improves production efficiency, reduces material waste, and ensures high surface quality—ideal for precision components manufacturing in industries such as 3C electronics, connectors, and small metal parts.
