Core Process Details
Roller Process
45# steel material → High-frequency heat treatment → Hard chrome plating → Precision outer circle grinding → Ensures high hardness and surface brightness.
The process begins with high-quality 45# steel, selected for its excellent mechanical properties and machinability.
High-frequency heat treatment is applied to enhance the material's hardness and strength, preparing it for demanding industrial use.
Hard chrome plating adds a protective layer that improves corrosion resistance and reduces friction during material feeding.
Precision outer circle grinding achieves a smooth, mirror-like finish, ensuring minimal wear and optimal contact with various materials.
This comprehensive process results in rollers that maintain high hardness (typically HRC58-62) and superior surface quality, extending service life and performance.
Transmission Gear
20CrMnTi gear steel → Carburizing and quenching → Super-hard and wear-resistant surface, with 4-gear precise meshing transmission to ensure error-free feeding.
Starts with 20CrMnTi alloy steel, known for its high strength, toughness, and suitability for gear applications in heavy machinery.
Carburizing process infuses carbon into the surface layer, followed by quenching to create a hard outer shell while keeping the core ductile.
The resulting super-hard surface (HRC58-62) provides exceptional wear resistance, capable of withstanding continuous high-load operations.
Features a 4-gear precise meshing system designed for smooth power transmission, eliminating backlash and ensuring zero-error feeding accuracy.
This advanced gear technology guarantees reliable, maintenance-free operation in high-precision stamping environments, reducing downtime and costs.
Frequently Asked Questions
What is the difference between an NC servo feeder and an air feeder?
An NC servo feeder uses a closed-loop servo motor with electronic cam synchronization to pull coil stock, giving programmable feed length (0–9999.99 mm) and ±0.03 mm repeatability. An air (pneumatic) feeder relies on a fixed gripper stroke and is cheaper but far less precise. For high-speed stamping and progressive-die work, the NCF servo roller feeder is the more accurate, flexible choice.
What feeding accuracy and feed length does the NCF servo roller feeder achieve?
The NCF feeder achieves an overall precision of ±0.03 mm when the mold uses positioning pins, thanks to closed-loop control plus a hollow, low-inertia roller for immediate stopping. Feed length is freely programmable from 0.1 up to 9999.99 mm through the human-machine interface, and feeding speed reaches 100–150 times per minute for high-throughput stamping press automation.
What coil materials and thicknesses can the NCF feeder handle?
Standard models handle steel, aluminum and copper coils from about 0.2 to 2.5 mm thick (the series spans 0.0–3.5 mm), in widths from 200 mm up to 1300 mm across the NCF-200 to NCF-1300 range. Thicker plate up to 6 mm and roller base-machine or thick-plate feeders can be customized — contact customer service to match your coil line.
What power supply and relaxation options does it need?
The feeder runs on 220 V single-phase or 380 V three-phase power, with standard three-phase 380 V configuration. It offers optional mechanical or pneumatic relaxation, chosen to match your press characteristics: mechanical relaxation is robust and maintenance-free for heavy-duty work, while pneumatic relaxation gives adjustable pressure for delicate or ultra-thin materials.
Where does the NCF servo roller feeder fit in a 3-in-1 coil line?
It is the precision feeding stage for punch press automation, typically following a decoiler and straightener in a coil-handling line. It suits automotive parts, precision electronic components and metal stamping, especially high-speed continuous stamping over 200 strokes per minute, multi-process forming, and precision processing of ultra-thin (<0.5 mm) or high-strength plates.
