Straightener/Leveling Machine
I'ts specially designed for correcting thin sheet materials such as stainless steel, copper, iron, and aluminum. With high-precision leveling rollers and a fine adjustment system, it ensures excellent flattening results for coil thicknesses ranging from 0.2mm to 1.2mm.
Material width (mm): 100-500
Material thickness (mm): 02-1.2
Correction Speed (m/min): 15
Product Characteristics
This series of straightening machine is specially designed to straighten thin stainless steel, copper sheet, iron sheet and aluminum sheet and other thin materials, which can achieve perfect leveling effect
There will be a curvature, and the dance music materials will be leveled and flat.
The leveling path is all made of imported SUJ2 material, heat-treated at HRC60℃, and then plated with hard chrome and then ground to ensure the uniformity of the
hard chrome layer and the cylindricity tolerance of each axis.
The leveling adjustment of this machine adopts a floating four-point balance fine-tuning device, with a dial indicator, which can quickly find the leveling.
In addition to the upper and lower leveling rollers inside the leveling machine, additional leveling auxiliary wheels are installed to prevent excessive pressure and
bending of the leveling rollers, strengthen the leveling strength and life of the leveling rollers, and improve the flatness requirements of the sheet surface.
The upper and lower rollers of this machine are fully driven to avoid the power loss and scratches on the surface of the material caused by the passive transmission of
the rollers on conventional models.
The addition of lubrication system extends the life of the machine and keeps the machine in a precise working state for a long time.
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.

FAQ
Q: How do I determine the right feeder size for my production line?
A: The feeder size depends on the material width, thickness, and feeding step distance required by your stamping press. Choosing the correct specifications ensures smooth operation and prevents feeding errors or misalignment.
Q: What factors should I consider when choosing a servo feeder machine?
A: When selecting a servo feeder, key factors include feeding accuracy (±0.05mm or better), maximum feeding speed (e.g., 20m/min), material compatibility (stainless steel, aluminum, etc.), load capacity, and control system (PLC or touchscreen). Ensure the machine matches your stamping process requirements.
Q: How long does it take to receive the feeder machine after placing an order?
A: Lead time for delivery typically ranges from 4 to 8 weeks depending on customization, production schedules, and shipping location. Once your order is confirmed, we will provide a more precise delivery estimate.
Q: What are your payment terms?
A: We accepts T/T payment, 30% deposit and 70% balance before shipping
Q: How often should I perform maintenance on my servo feeder machine?
A: Routine maintenance should be conducted weekly for basic cleaning and lubrication, while a more thorough inspection should be done monthly to check for wear on rollers, belts, and electrical components. A full servicing is recommended every 6-12 months depending on usage intensity.
Q: What are the most common issues with feeder machines, and how can I troubleshoot them?
A: Common issues include misalignment, inconsistent feeding accuracy, or motor failure. Check for loose bolts, dirt buildup, or software calibration errors. If problems persist, refer to the user manual or contact technical support.
Q: Do you provide on-site repair services if my machine breaks down?
A: Yes, we offer on-site repair services for major issues, along with remote troubleshooting support for minor problems. For urgent cases, we can dispatch a technician within 24-48 hours, depending on your location.
Q: What's the package of your coil feeding machines?
A: For the coil feeding equipment that go LCL shipping, We will use plastic films wrap on the equiment, and then fix it into a wooden box.
For the large coil lines that go FCL shipment, We will fix each part with ropes on the shipping container and then wrapped them with plastic films.
