Incoming Coil Condition Controls the Process
Two coils with the same nominal diameter can behave differently because of spool diameter, layer position, residual coil set, 抗拉強度, torsion, surface lubrication and previous drawing or tempering.
Before equipment selection, record:
- material grade and mechanical-condition range;
- wire diameter and tolerance;
- spool dimensions, coil weight and winding direction;
- minimum/maximum residual coil diameter;
- visible helix, twist, kinks and crossovers;
- surface finish, coating or lubrication;
- final cut lengths and product family;
- allowable straightness, length error and end condition.
Representative sample coils are required. Short hand samples do not reproduce payoff tension, layer changes or long-run wear.
Roller, Rotary or Combined Straightening
The correct method depends on cross-section, 物質狀態, 直徑, target length and surface requirement.
| 方法 | Typical Strength | 主要驗證風險 |
|---|---|---|
| Multi-plane roller straightener | Adjustable gradual reverse bending; suitable for many wire and profile applications | Roller groove, plane alignment, surface contact and residual helix |
| Rotary straightener | Useful for round linear material and long cut lengths; can combine with servo feed/cut | Tool rotation, 熱, contact wear, diameter window and surface marking |
| Combined system | Adds flexibility where one stage cannot control all deformation modes | More settings, more contact and more changeover variables |
Novo Precision publicly offers both roll and rotary wire straightening and pairs rotary straighteners with feed/cut systems for stainless and spring steel. Ravni uses different straightener types for hexagonal and round wire. These references demonstrate that method selection is application-specific; they do not prove the 0.3 mm project values.
Recommended Continuous Process
1. Controlled payoff
The payoff stand supplies wire without tangles, sudden tension changes or uncontrolled overrun. Dancer, brake or active payoff control is selected from spool inertia and wire sensitivity.
2. Guide and pre-alignment
Guides bring the wire into the straightener without side loading. Contact radii and materials must not scratch or flatten the wire.
3. 拉直
Rollers, rotary tools or a validated combination apply alternating controlled bending to reduce residual coil set and helix. Settings include tool position, groove/contact geometry and speed.

4. Servo feed and length control
The feed system advances the programmed length. Encoder location, wheel pressure and slip detection determine whether controller counts represent actual wire travel.
5. Cut-to-length
The cutting method must match the diameter, material and end requirement. A fixed shear, flying shear or another cutting head may be selected. “Flat” and “burr-free” must be converted into measurable squareness, burr and deformation limits.
6. Discharge and collection
The cut wire must be supported so it does not bend, tangle or strike hard surfaces. Long slender pieces may need guided discharge or length-specific collection.
7. Release, remeasure and classify
After cutting, release the sample from feed-wheel, guide and collection forces and allow any specified conditioning time before measurement. Remeasure cut length, straightness/bow, end quality, diameter and surface by the agreed method. Classify each inspected sample as OK only when every required characteristic is within its limit. A 足夠的 result triggers the defined response: adjust the validated recipe and verify a new sample, segregate affected production since the last accepted check, or stop the line when the reaction plan requires it. A cut piece is not fed through an improvised correction loop unless that rework route has been separately validated.
Record coil/lot, recipe, tool life, measurement result, OK/NOK decision and disposition where traceability is required. Production release resumes only after the required confirmation sample is OK.

Real Fine Wire Straightening and Cutting Video
The following video is published by the Straightening Machine YouTube channel as “Straightening and Cutting Machine for Stainless steel fine wire after Spring tempering.” It confirms the material application and machine process. It does not, by itself, prove 20 米/分鐘, 0.3 mm capability, the stated tolerance, end quality or production yield.
Defining Straightness for Cut Wire
Wire straightness should not be described only as “perfectly straight.” The acceptance method must specify:
- cut sample length;
- horizontal or vertical posture;
- support points or reference surface;
- maximum bow, gap, deviation or runout definition;
- measurement location and resolution;
- whether residual helix/twist is controlled separately;
- conditioning time after cutting, if elastic recovery changes the result.
For very fine wire, gravity, electrostatic effects, handling and gauge force may influence the apparent result. The customer method should be reproduced during sample testing.
Cut Length and End Quality
The original ±0.25 mm/m phrase is ambiguous. A cut-length tolerance is normally tied to a specified nominal length and measurement method; a straightness tolerance over one meter is a different characteristic. The project specification must not combine them.
| Acceptance Characteristic | Required Definition |
|---|---|
| Nominal cut length | Each product length and permissible variation |
| Length datum | End-to-end, gauge stops or another drawing definition |
| End squareness | Maximum angular or height deviation across the diameter |
| Burr | Maximum height and inspection magnification/method |
| End deformation | Allowed flattening, pull, hook or rollover |
| Surface | Scratch depth/appearance and contamination rule |
Tool Material, Wear and Changeover
Tool material cannot be selected from “stainless steel” alone. Contact pressure, wire hardness, 速度, lubrication and surface requirements determine whether carbide, ceramic, hardened steel, polymer or another contact is appropriate.
A validated maintenance plan should define:
- tool/groove inspection interval;
- wear limit and replacement criteria;
- cleaning method and permitted lubricant;
- setup master or first-piece approval;
- recipe and tool identification;
- revalidation trigger after material, 直徑, tool or speed changes.

Sample Test Matrix
| Test Variable | Minimum Coverage |
|---|---|
| Coils | Outer/middle/inner layer and more than one lot |
| 材料 | Lowest/highest tensile condition proposed |
| 直徑 | Minimum/nominal/maximum within supplied tolerance |
| 速度 | Staged speeds up to the requested maximum |
| Cut lengths | Shortest, longest and highest-volume products |
| Quality | 直率, 長度, end, surface and diameter |
| Duration | Long enough to observe payoff changes, heat and tool wear |
| Exceptions | Breaks, tangles, slip, miscuts and manual adjustments |
Only combinations demonstrated as conforming should enter the commercial guarantee. A maximum no-load or short-run speed is not the same as a validated production speed.
Machine and Internal Links
Review the UBS02 Flying Shear Straightening Machine and the broader 醫療線矯直解決方案 when the final product is a medical wire component. Product specifications and application requirements must still be reconciled with sample tests.
What This Solution Does Not Promise Without Evidence
- that every spring-tempered stainless wire behaves the same;
- validated 0.3 mm production capability from a video alone;
- 20 m/min while simultaneously meeting every length, straightness and end requirement;
- that
±0.25 mm/mis a valid cut-length specification until clarified; - no burr, no scratch or perfectly flat ends without defined inspection limits;
- complete removal of internal stress;
- 99.9% consistency, a specific yield or labor saving;
- suitability for a medical application without the customer's controlled specification and validation.

Frequently Asked Questions
Is rotary straightening always better for fine round wire?
不. Rotary, roller and combined approaches each have application windows. The choice depends on material, 直徑, 長度, surface and quality requirements.
Can 0.3 mm wire run at 20 米/分鐘?
Those are reported project inputs. They become a validated combination only after representative coils meet straightness, 長度, end and surface criteria during a sustained trial.
What does ±0.25 mm/m mean?
The source phrase is ambiguous. The customer must confirm whether it describes cut-length error, straightness over one meter or another characteristic before it is used commercially.
How do you prevent scratches?
By validating guide, roller/tool material, 壓力, alignment, cleanliness and lubrication for the actual surface. The acceptance limit must be measurable rather than stated as “no scratches.”
How is tool wear controlled?
Use inspection intervals, defined wear limits, first-piece checks and recipe/tool traceability. Long-run coil trials are required because short tests may not reveal wear or heat effects.
