Zigzag Servo Feeder for Circle Blanking Lines
Henli automatic zigzag servo feeder is a 2-axis press feeding system for cookware, kitchenware, LED lighting parts, washers, motor laminations, and other round metal blanks. The feeder shifts the strip left and right while feeding, creating a staggered circle blanking layout that helps reduce scrap compared with normal straight feeding.
Buyer Intent
Zigzag servo feeding for circle blanking and swing feeding
A zigzag servo feeder, also searched as a left-and-right swing feeder or servo swing feeder production line, is selected when round parts need better coil material utilization. The page focuses on circle blanking, disc blanking, and nested metal stamping rather than general NC roll feeding.
How the feeding path works
The feeder uses X-Y motion to feed forward and shift laterally according to the circle diameter, material width, and programmed nesting pattern. Operators enter key production data on the HMI, and the control system calculates the feeding path for staggered blanking.
When to choose zigzag feeding
Use this machine when a straight feed layout wastes too much material between circles, or when cookware, lighting, washer, motor, or hardware production needs a repeatable circle blanking line.
When to choose standard feeding
For general straight feeding without left-right motion, see the NC Servo Feeder page. For thick plate or special coil data, confirm the complete line before model selection.
Selection Logic
How to choose a zigzag feeder for a press line
Model selection should start from actual coil and blank data. The same feeder model can behave differently when the circle diameter, coil width, material strength, press speed, and die row pattern change.
Confirm blank geometry
Provide circle diameter, product drawing, web allowance, and whether the die needs one-row, two-row, S-pattern, or W-pattern blanking.
Confirm coil data
Material type, thickness, width, yield condition, coil weight, coil I.D./O.D., and surface protection decide feeder width and upstream equipment.
Match press and die
Press tonnage, SPM, stroke, feed timing, die release, and available space decide the line rhythm and feeder installation method.
Plan the complete line
A circle blanking line usually combines a decoiler, leveler, zigzag servo feeder, press, die, and optional stacking or shearing devices.
Check material utilization
Use real diameter and strip width data. The circle blanking material utilization guide is a useful support article.
Core Functions
Key functions for material-saving circle blanking
The value of this machine is not only servo feeding accuracy. Buyers usually need a system that can calculate the staggered layout, move laterally with stability, and connect with the existing press and coil handling line.
Higher material utilization
The zigzag feeding path arranges circular blanks in a staggered pattern to reduce scrap web between parts. Typical projects target 7%-15% material saving, while actual results depend on blank size and strip width.
2-axis servo movement
Forward feeding and left-right shifting are controlled by servo motion, helping the strip follow the programmed blanking pattern for cookware, LED light parts, washers, motor laminations, and other round parts.
PLC and HMI calculation
Operators input material width, circle diameter, and feed step on the touch screen. The system calculates the movement path, reducing manual layout calculation during setup.
Straight feeding option
When the job does not require staggered blanking, the feeder can be used for normal straight feeding. This makes it useful for factories that switch between round and non-round stamping jobs.

Line Integration
Video and complete circle blanking production line
A practical zigzag circle blanking line is not only the feeder. The upstream coil handling equipment, leveler, press, die, and downstream collection method all affect utilization, speed, and daily operation.
Read the video as a line-motion reference
The video is useful for understanding the working rhythm of a zigzag blanking line, but the main selection decision should still come from coil data, blank diameter, die layout, and press speed.
Use it together with the line steps below to check how the decoiler, leveler, feeder, press, and optional handling equipment work as one production cell.

Why the nesting pattern matters
The blanking result depends on the relationship between material width, circle diameter, web allowance, and die layout. A wider strip does not automatically mean better utilization unless the row pattern and press motion are matched.
For new projects, send the part drawing and material data first. Henli can review whether a standard NC model, reinforced B-Series, or thick-plate configuration is more suitable.
Applications
Target applications for zigzag circle blanking
The machine is most useful when the finished part is round or nested in a way that benefits from side-shift feeding. If the job is fixed-pitch rectangular stamping, a standard servo feeder may be enough.
Cookware and kitchenware
Stainless steel pots, pan covers, bowls, cooking discs, and similar round blanks where material cost is important.
LED lighting parts
LED downlight heat sinks, lamp covers, and circular lighting parts produced from metal coil stock.
Automotive and motor parts
Circular automotive components, motor laminations, clutch-related parts, and other repeated round blanks.
Hardware and washers
Water heater tanks, washers, covers, and other circular hardware accessories where scrap reduction affects unit cost.

Compact precision zigzag feeder
For small-format precision stamping and narrow strip projects where material saving still matters. Confirm material width, circle diameter, feed pitch, and press speed before final selection.
Wide zigzag servo feeder
For wider circle blanking work such as cookware, large LED parts, and automotive-related round blanks. The upstream decoiler and leveler must match the coil width and weight.
Quotation Checklist
Send coil and blank data for zigzag feeder selection
For a realistic quotation, Henli needs the production data that affects feeder width, servo capacity, lateral stroke, line height, upstream equipment, and press synchronization.
Buyer Questions
FAQ for zigzag servo feeder buyers
These answers are written for procurement and engineering review. Final model and line configuration should be checked against actual coil, blank, press, and die data.
How much material can a zigzag servo feeder save?
Many circle blanking projects target 7%-15% material saving compared with straight feeding. The actual result depends on material width, circle diameter, web allowance, die layout, and how many rows can be nested across the strip.
What is the difference between a zigzag servo feeder and a normal NC servo feeder?
A normal NC servo feeder mainly feeds the strip forward at a controlled pitch. A zigzag servo feeder adds left-right shifting so circular blanks can be arranged in a staggered pattern. It can also be used for normal straight feeding when the job does not need zigzag motion.
Is this the same as a left and right swing feeder?
In buyer search language, yes, a left-and-right swing feeder or servo swing feeder production line usually refers to the same type of side-shift feeding concept for circle blanking. Henli uses the term zigzag servo feeder for the NC-controlled press feeding machine.
What data is needed before model selection?
Please provide material type, thickness, width, coil weight, coil I.D./O.D., circle diameter, part drawing, press tonnage, SPM, feed height, die information, and expected production mode. These details decide whether a standard, B-Series, or custom thick-plate configuration is appropriate.
Can the feeder work with a decoiler, leveler, and existing press?
Yes, the feeder is commonly integrated with a hydraulic decoiler, precision leveler, power press, die, and optional stacking or shearing devices. For an existing press line, the feed height, timing signal, installation space, and die release method should be confirmed first.
What speed and accuracy should we expect?
The current page data lists a maximum feeding speed up to 15 m/min and feeding accuracy within +/-0.08 mm. Actual production speed depends on press SPM, feed length, lateral travel, circle diameter, and the chosen blanking pattern.
Do you provide installation support for international projects?
Henli can provide English documentation, video guidance, and remote support. For complete production lines, onsite installation and training can be discussed according to the project scope, destination, and service schedule.
