NC Servo Feeder
NC Servo Feeder
YouYi's NC Servo Feeder is a precision coil and strip feeding solution engineered for modern stamping and press automation lines. Driven by a high-performance servo system and a closed-loop encoder feedback, the servo roll feeder delivers repeatable feeding accuracy (typical ±0.02 mm; short-distance accuracy ≤ ±0.01 mm), high responsiveness and flexible feed-length programming. Typical configurations support material widths from 100 mm to 600 mm and thickness ranges from 0.1 mm up to 6.0 mm with servo power options from 2 kW to 5 kW depending on model.
Designed for seamless integration with decoilers, straighteners, and press transfer systems, the NC Servo Feeder supports both mechanical and pneumatic release modes and is also available in a zig-zag feeding model for circular blank layout applications. The standard control system features a PLC with touchscreen HMI for intuitive operation and efficient parameter setting.
Achieving ±0.02mm feeding accuracy means:
• Reduced tolerance stack‑up in downstream operations
• Lower defect rates and material waste
• Stable performance in demanding and high‑speed stamping environments
• Reliable integration with automated press lines and tooling

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 do I choose the right decoiler, straightener and feeder?
A: Select based on material type, width, thickness, coil weight, and required speed. Match decoiler capacity to coil size, choose a straightener for material strength, and a feeder that meets feed length and precision. Ensure compatibility with your press and automation level.
Q: Coil feeder vs servo feeder: what’s the difference?
A: A coil feeder is a broader system for continuous coil feeding, often integrated with decoiler and straightener. A servo feeder uses servo motors for precise, programmable feeding, ideal for short pitches and high accuracy applications.
Q: How to choose decoiler capacity?
A: Select a decoiler rated 10–20% above your maximum coil weight. Confirm inner diameter (I.D.) compatibility and outer diameter limits. Adjustable mandrels are recommended if you run multiple coil sizes.
Q: What feed precision can I expect?
A: Servo feeders typically achieve ±0.01–0.05 mm, with high-end models reaching ±0.005 mm. Mechanical feeders usually provide ±0.02–0.1 mm. Actual accuracy depends on material properties and straightening quality.
Q: How does material affect machine selection?
A: High-strength materials need stronger straightening and drive systems. Thin materials require low-pressure handling. Soft materials like aluminum need anti-scratch solutions.
Q: What affects feeding accuracy most?
A: Key factors include feeder precision, servo tuning, straightener setup, material quality, and press stability. Poor setup or worn dies can reduce accuracy.
Q: What spare parts should be prepared?
A: Common spares include bearings, belts, sensors, seals, guide blocks, and lubrication parts. Keeping key components reduces downtime and improves maintenance efficiency.
Q: Can feeders be retrofitted to existing presses?
A: Yes, most systems support retrofitting. Check press dimensions, feed height, control compatibility, and safety requirements before installation.
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 is the maintenance cycle?
A: Daily cleaning and inspection; weekly check belts, air lines; monthly inspect bearings and guides; yearly replace worn parts. Adjust frequency based on operating hours and workload.
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.
Q: What is the typical lead time?
A: Standard machines usually take 4–8 weeks. Customized systems or full production lines may require 10–20+ weeks depending on complexity and production schedule.
