NCF Series Zigzag Servo Feeder for Circle Blanking
Zigzag servo feeder — the Jingcui NCF Series combines a servo roller feeder with an independent oscillating box for X-axis (left-right) lateral shift, nesting round blanks on the strip to save material in circle blanking, while closed-loop servo control holds feeding accuracy within ±0.03mm.
What Is a Zigzag Servo Feeder?
A zigzag servo feeder builds on a standard NC servo roller feeder. The roller feeder advances the coil strip forward as usual. An add-on oscillating box — a caterpillar/track traverse plus a drive (power) electrical box — then shifts the strip laterally (X-axis, left to right) to nest round blanks in a staggered layout.
This lateral (X-axis) oscillation is what separates a zigzag feeder from a standard NC servo roll feeder. Instead of laying round blanks in a single straight line, the machine offsets each row so blanks interlock. As a result, you blank more parts from the same coil and throw away less scrap. Exact saving depends on blank diameter and layout.
Note: the oscillating-box specifications (traverse stroke, swing amplitude, drive power, and saving rate) are pending factory confirmation.
Applications: Where Zigzag Feeding Pays Off
The NCF Series is built for circle blanking and round-part stamping. Typical workpieces include:
- Motor stators and rotors
- Compressor shells for refrigerators and air conditioners — see our appliance metal stamping page
- Clutch discs and brake pads
- Pulley blanks and wheel parts
- Cookware, lamp covers, and stainless tableware blanks
Which industries run these parts? Electric motors and electronics, home appliances, automotive, lighting, and hardware. For example, an appliance maker blanking compressor shells can cut material cost noticeably with a nested layout.

Why Choose Our Zigzag Servo Feeder
Save Material Through Lateral Oscillation
Lateral (X-axis) oscillation nests round blanks on the strip, cutting the scrap between parts. So the same coil yields more finished blanks, which lowers your per-part material cost.
High-Precision Closed-Loop Feeding
Computer closed-loop feedback keeps accuracy within ±0.03mm. Therefore, your blank layout stays accurate over long production runs.
Programmable Multi-Stage Feeding
Enter up to 20 feed-length groups with 999 strokes each (optional), plus 3-stage manual speed for precise material positioning into the die.
Durable Feed Mechanism
Hollow, HR60° hard-chrome-plated rollers are lightweight with low inertia, so they resist wear and hold up under continuous stamping.
Line Integration
A typical circle blanking line pairs this zigzag servo feeder with an uncoiler and a straightener machine, then feeds into a stamping press and die. Stacking, shearing, and scrap handling are available as options. For straight-line progressive-die jobs, our roller feeder series may be a better fit.
Frequently Asked Questions
What is the difference between a zigzag feeder and a standard NC servo feeder?
A zigzag feeder adds an oscillating box that shifts the strip laterally (X-axis, left-right) to nest round blanks and save material. A standard NC servo feeder moves the strip forward only, which suits progressive-die and linear layouts.
How much material does zigzag feeding save?
The saving depends on blank diameter and layout, and is pending factory confirmation for our oscillating box. Lateral nesting reliably reduces scrap between round blanks versus straight-line feeding.
What width can you supply?
The NCF series covers 100mm to 1300mm material width across ten models. Non-standard widths are available on request.
Can you help with the full circle blanking line?
Yes. We supply the feeder, uncoiler, straightener machine, press interface, and optional stacking or scrap handling as a complete turnkey line.
