Réponse rapide : Le jeu entre les lames de cisaille est réglé à 5–10 % de l'épaisseur du matériau, mesuré au point de coupe. Pour de l'acier doux de 6 mm, cela représente un jeu de 0,30 à 0,60 mm, mais ce pourcentage n'est qu'une plage de départ, pas une réponse définitive. Confirmez la valeur de travail par une coupe d'essai sur votre matériau réel, vérifiez le jeu en trois points le long de la lame à l'aide d'un jauge d'épaisseur, et considérez toute hauteur de bavure supérieure à 5 % de l'épaisseur comme un signal d'alerte pour revérifier le jeu.
Note d'ingénierie : Le jeu entre les lames de cisaille est l'espace perpendiculaire entre les arêtes de coupe supérieure et inférieure, exprimé en pourcentage de l'épaisseur du matériau. Il régit le rapport entre la zone polie et la zone fracturée sur le bord de coupe, la hauteur des bavures et la charge de la lame par coup. Le flux de travail de réglage et de contrôle qualité de Maxtor Metal traite le jeu comme un paramètre de processus spécifique au matériau — et non comme un réglage fixe de la machine — et le documente pour chaque travail en même temps que l'état de la lame et les mesures du rayon d'arête.[→ See Maxtor Metal shear blade specifications and material options]
Le jeu entre les lames de cisaille est l'écart horizontal entre les arêtes de coupe supérieure et inférieure au point de coupe, et sur une cisaille guillotine, il est généralement réglé en pourcentage de l'épaisseur du matériau plutôt qu'en valeur fixe. Une mauvaise valeur entraîne un coût bien concret : le rebut de bande dû à une mauvaise qualité d'arête représente 5 % à 10 % du coût total de possession — un chiffre qui s'accumule à chaque cycle de réaffûtage.
The 5–10 percent rule is a starting range rather than a specification. Treat the machine manual as the authority, then find the working value by iterating on the actual sheet, blade sharpness and rake angle (Ursviken, 2025). Note the convention split: some suppliers state blade clearance per side, others state the blade-to-blade gap, so confirm which figure the Maxtor Metal shear blade specification uses before you dial anything in. Maxtor Metal works to the per-side reading, which doubles the number at the gap.

Mécanique des arêtes de coupe
Shear blade clearance decides how a cut fails, and that failure is what produces either a clean edge or a burr. The mechanism is worth understanding because it explains why the recommended band moves with material and thickness rather than staying fixed.
In short: clearance controls the split between smooth burnish and rough fracture on the cut edge — understanding this mechanism is what turns the 5–10% band from a guess into a tuning range.
Burnish and fracture zones
A sheared edge is not one surface. It is four zones stacked through the material thickness: rollover, where the blade first contacts and plastically deforms the sheet into a rounded, bent region; the burnish or shear zone, a smooth band formed while the blade compresses and rubs the material; the fracture or rupture zone, a rougher angled region where the crack propagates; and the burr, thin elongated metal pushed out at the exit edge (ispatguru, 2019; AHSS Guidelines, 2021).
Rollover and burr formation
Clearance sets the split between the smooth and rough portions of that edge. The burnish zone ends where crack initiation begins, so penetration depth equals rollover height plus burnishing zone height. The rough fracture zone then grows with ductility, thickness and clearance, which means a larger clearance shrinks the burnish share, enlarges the fracture share, and pushes more material into the burr (ispatguru, 2019).
Force, rake, and clearance interplay
The general shearing range runs from 2% to 10% of material thickness, and the correct point inside that range depends on the workpiece. Harder materials and greater thickness need larger clearance. Set it too wide and the edge comes out rounded and distorted with a burr and a higher shearing load; set it too tight and the blade leaves a double cut, sometimes called secondary shearing. Ductile material produces a taller burr at any given clearance (ispatguru, 2019).
That is the mechanism behind the band. The next section turns it into numbers.
La règle des 5–10 %
The 5–10 percent rule says the shear blade clearance should sit between 5% and 10% of the metal thickness you are cutting. That band is the starting point for mild steels, not a universal setting, and the AHSS Guidelines note that published recommendations place mild-steel die clearance at 5% to 10% of metal thickness. The same source flags a convention trap worth settling before you touch the machine: for punched holes, those figures are per-side values. Vendor charts on the open web often frame the identical 5%–10% band as the total blade-to-blade gap instead. Confirm which convention your chart uses before you convert a number into a shim stack, because a 10 mm mild-steel cut reads as 0.5–1.0 mm per side under one reading and 0.5–1.0 mm total under the other.
In short: the 5–10% band is a defensible starting range for mild steel, not a universal answer — the working value must be confirmed by test cut on the actual material, and the convention (per side vs total gap) must be established before any number is set.
Material-based bands
The band widens as the material gets stronger. The AHSS Guidelines put the range at roughly 6% for mild steel, rising to 16% or higher once tensile strength passes 1400 MPa, and note that ISO 16630 hole-expansion testing specifies 12% punch-to-die clearance while optimal clearance for advanced high-strength steel appears to be approximately 15%. Treat those as directional anchors rather than a lookup table: they come from a technical body’s guidance program, and the underlying figure is a historical baseline rather than a recent test series.
For AHSS and UHSS applications where standard D2 blades are reaching their clearance and wear limits, see the tungsten carbide inlaid shear blades ROI guide for AHSS lines for a full TCO comparison.
When to deviate
Deviate upward when the material work-hardens or when edge quality matters more than tool life. Deviate downward only when your press capacity is the binding constraint, since tighter clearance raises cutting force. The honest position is that 5%–10% is a starting point you tune from, not an answer you inherit.
Parallelism and thickness effects
Clearance is only as good as its consistency along the blade. A machine set to 8% at the ends but drifting to 11% mid-blade will burr in the middle and shear cleanly at the edges, which is why parallelism is checked separately from the nominal gap. Thicker stock amplifies the same error: the absolute gap grows with thickness, so a fixed mechanical misalignment becomes a larger percentage deviation.
SOP de réglage
A repeatable shear blade clearance setup follows one sequence: baseline the gap, verify parallelism, lock, test cut, iterate. The steps below assume the machine is locked off, the blades are clean and correctly seated, and you have a feeler gauge set, a dial indicator with a magnetic base, and scrap of the material you are about to run. Budget 30 to 45 minutes for a first setup on a machine you do not know well.
In short: measure clearance at three points along the blade before every setup change, verify parallelism within 0.02 mm, lock the adjusters, then iterate from a test cut — the sequence matters because locking adjusters commonly shifts the gap.
Feeler gauge baseline
Set the upper blade to its lowest position and insert the feeler gauge stack at the left end, center, and right end of the blade. Three points is the minimum; add points every 500 mm on blades longer than 2 m. Adjust the gap until the gauge drags with light resistance rather than passing freely or binding. Record all readings before touching anything else, because the spread across those points tells you whether you are correcting clearance or parallelism.
Dial indicator calibration
Mount the dial indicator on the lower blade and sweep the upper blade through its stroke, recording readings at several positions along the length. Blades should sit within 0.02 mm of each other, and the gap needs immediate recalibration once it exceeds that. Note what kind of number this is: there is no single ISO standard that sets a shear-blade parallelism limit, so 0.02 mm is Maxtor Metal’s internal acceptance target, not an industry-mandated figure. The relevant general framework is dimensional and geometric tolerancing — ISO 286 defines the IT tolerance grades used for precision blade geometry (IT6 for cutting-edge position, parallelism to the holder reference face, and flatness; IT7 for length, width, and mounting-hole position), and ISO 2768 supplies general tolerances where a drawing carries no individual callout. Treat the 0.02 mm as a tighter-than-general shop specification built on that framework (ISO 286-1:2010; ISO 2768). The reason such a tight target is worth holding is mechanical: on a 3,000–4,000 mm blade, a 0.1–0.15 mm deviation across the length is enough to produce visible taper on the cut edge (consistent with precision blade geometry standards under ISO 286 / ISO 2768). Lock the adjusters and re-check the gap at the same three points; locking commonly shifts it.
Test cut and iteration
Run a slow test cut on scrap and read the edge. Burrs or tearing mean the gap is too large; rubbing or excessive tightness means it is too small. Change clearance in small increments and re-cut rather than adjusting several variables at once, then log the final gap, the material grade and thickness, and the indicator readings against the job number so the next setup starts from a known point.
Each regrind removes material from the blade thickness. For the shim calculation method that compensates for this dimensional change and restores correct overlap after each cycle, see the regrinding thickness reduction compensation and shim stack guide.
Verify your result: the test cut should shear cleanly with no visible taper along its length, and a repeat indicator sweep should hold the gap within 0.02 mm after the adjusters are locked.
Cas pratique : correction des bavures excessives sur S355 de 6 mm
The clearest way to see why 5–10% is a starting rule and not a fixed answer is to walk through a commissioning-style troubleshooting case. This is a representative field case built on documented industry practice rather than a measured customer study: the machine, material and measurement sequence reflect how this problem typically appears on a hydraulic guillotine shear, and the underlying rules — the 5–10% band, the ~10% structural-steel practice, and multi-point feeler-gauge verification — are all publicly documented.
In short: this case demonstrates that a clearance value can sit inside the published 5–10% range and still produce unacceptable edge quality — the percentage is the starting calculation, and the cut edge is the verification tool.
The situation
| Paramètre | Valeur |
|---|---|
| Application | Hydraulic guillotine shear |
| Matériau | S355 structural steel |
| Épaisseur nominale | 6.0 mm |
| Measured thickness | 5.94–6.06 mm across the test sheets |
| Lame | Hardened cold-work tool-steel shear blades |
| Initial clearance | ~0.30 mm |
| Target window | ~0.30–0.60 mm (5–10% starting rule) |
The problem appeared after the machine was switched from thinner sheet to 6 mm structural steel. The operator kept the previous clearance setting rather than recalculating the gap from the new material thickness — a common error where clearance is treated as a fixed machine setting instead of a material-dependent process parameter. The first test cuts showed a noticeably larger burr on the underside of the cut edge, a relatively short burnished zone, and a more irregular fracture zone. The operator suspected dull blades and considered replacing them.
Attempt 1 — replace the blades (rejected)
The first response was to suspect blade wear. Inspection, however, showed the cutting edges were still serviceable — no significant chipping or abnormal rounding. Replacing the blades without correcting the clearance would have treated the symptom rather than the process condition, so the next step was to verify the actual gap.
Measurement sequence
The machine was stopped and isolated per the site’s maintenance procedure. Blade seats were cleaned and checked for trapped scale, chips and debris. Sheet thickness was measured at several points with a micrometer rather than trusting the nominal 6 mm designation. Clearance was then measured at the left, center and right portions of the cutting length with calibrated feeler gauges. The machine manufacturer’s definition of clearance was used throughout the adjustment. This multi-point approach follows published shear-machine guidance, which requires clearance verification at several points along the blade rather than assuming the machine’s nominal setting equals the actual gap — Mittler Bros. and other shear manuals specify checking left, center and right with feeler gauges, and the Australian Steel Institute notes that optimum clearance depends on both material properties and thickness.
Attempt 2 — keep the 5% setting (insufficient)
After measurement, the initial gap was approximately 0.30 mm — about 5% of the measured 6 mm thickness:
6.0 mm × 5% = 0.30 mm
That value was technically inside the general 5–10% starting range, yet edge quality remained unsatisfactory. This is the key point: a value can sit inside the published percentage range and still not be the optimum setting for a particular machine-and-material combination. Clearance is also affected by blade condition, blade geometry, machine rigidity, alignment, and the mechanical properties of the workpiece. Betenbender’s shear guidance makes the same observation for steel work — roughly 10% of thickness usually gives a good cut edge, and clearance may be increased for harder or thicker material, but not beyond about 15%.
Attempt 3 — increase clearance (resolved)
Clearance was increased progressively toward approximately 0.50–0.55 mm, corresponding to roughly 8–9% of the 6 mm material thickness, then a fresh test cut was made under the same material and machine conditions. Edge quality improved visibly. The important caveat: this is not a claim that 0.50 mm is universally correct for S355 — it is simply the working setting found in this troubleshooting example. Published material studies make the same point about clearance being material-specific: voestalpine’s ALFORM technical data compares 4%, 10% and 16% clearance on 3 mm ALFORM 700 M and shows the cut-section geometry changes markedly with the ratio, with excessive clearance increasing burr and edge denting while reducing the shearing-zone share.
Effect, recorded honestly
Rather than inventing precise burr-height numbers, a credible record notes the observable change:
| Paramètre | Initial condition | After adjustment |
|---|---|---|
| Matériau | S355 | S355 |
| Épaisseur nominale | 6 mm | 6 mm |
| Measured thickness | 5.94–6.06 mm | 5.94–6.06 mm |
| Autorisation | ~0.30 mm | ~0.50–0.55 mm |
| Clearance ratio | ~5% | ~8–9% |
| Blade condition | Serviceable | Same |
| Test batch | Same heat / comparable material | Same |
| Burr | Pronounced / unacceptable | Visibly reduced |
| Cut edge | Irregular fracture zone | More uniform fracture |
| Blade change | Not required | Not required |
If a team wants to make this rigorous, the fields worth adding are burr height (mm), rollover height (mm), burnished-zone and fracture-zone percentages, cut-angle deviation, machine hydraulic pressure, number of strokes, and blade edge radius.
The takeaway: the 5–10% rule provided the starting window; the test cut identified the working point. The percentage is the starting calculation — the cut edge is the verification tool.
This chain is worth internalising: 5–10% rule → 6 mm S355 gives a 0.30–0.60 mm starting window → measurement shows 0.30 mm gives poor edge quality → step up to ~0.50–0.55 mm → test cut confirms the improvement → do not market 0.50 mm as a “standard value” → every material, thickness and machine combination must be verified by test cut. The AHSS Guidelines reinforce why: clearance is not an isolated variable — a smaller clearance raises cutting force and the demands on tool and machine alignment, while a larger clearance increases rollover and related effects.
Contrôle qualité et maintenance
In short: set a numeric burr height limit before the job starts, log clearance and material lot per job, and treat rising burr height or an edge radius above 0.2 mm as mandatory regrind triggers — not subjective judgements.
Burr height limits and triggers
Burr height is the fastest field check on a shear, and it is the one most often left unmeasured. Set a numeric limit before the job starts, then treat any exceedance as a trigger rather than a nuisance.
A practical default is 5% of material thickness. On 3 mm mild steel that is 0.15 mm, measurable with a deburring gauge or a bench micrometer across the burr crest. Project drawings and customer acceptance criteria override the default whenever they are tighter.
Two triggers should stop the line:
- Burr height above tolerance on two consecutive cuts after a clearance check.
- Edge radius at or above 0.2 mm, measured on the blade bevel with a radius gauge or a 20× magnifier.
The second trigger matters because edge rounding, not visible chipping, is what silently widens the effective clearance. A blade that looks serviceable can already be cutting 0.05 mm wider per side than the setup sheet says. As with the parallelism target, the 0.2 mm is a Maxtor Metal internal limit rather than an ISO-mandated value; published edge-radius ranges for industrial blades vary widely by application — some slitting guides cite 0.05–0.30 mm, disc-shear references hold below 0.05 mm, and general deburring practice references edge-break specifications such as ISO 13715. That spread is exactly why you set the limit against your own acceptance criteria rather than assuming one number fits every line.
For a measurement-based rotation trigger and audit-ready log template that standardises this decision across an entire blade inventory, see the SOP sur le calendrier de rotation des lames réversibles à 4 arêtes et les critères de réaffûtage.
Conseil de pro : Log clearance, material lot, and burr height per job in one sheet. After a few weeks the log shows whether drift tracks a specific material lot, a specific operator, or the blade itself, which turns regrind scheduling from guesswork into a trend line.
Defect diagnosis and corrective actions
Match the defect to the cause before touching the blade. Most burr and edge complaints trace back to one of four conditions, and each has a different fix.
| Defect | Likely cause | Mesures correctives |
|---|---|---|
| Tall, rolled burr on one side | Clearance too wide on that side | Re-check parallelism, reduce gap toward the lower band |
| Short, brittle burr with edge chipping | Clearance too tight | Open the gap, inspect the bevel under 20× magnification |
| Burr varies along the cut length | Blade not parallel or ram misalignment | Re-shim and verify straightness before the next setup |
| Clean cut, sudden burr spike mid-run | Edge wear or chipping | Measure edge radius, then decide regrind or replace |
When chipping appears suddenly or in a consistent location along the blade, the defect pattern itself carries diagnostic information. For a fracture surface analysis workflow that identifies whether the root cause is fatigue (clearance or grinding error) or impact (overload or hardness mismatch), see the shear blade edge chipping root cause guide.
That last decision follows a chipping-depth ladder. Light chipping under 0.2 mm clears with standard stock removal of 0.25–0.35 mm. Moderate chipping between 0.2 mm and 0.5 mm needs deeper removal and a 20× inspection of the bevel. Severe chipping above 0.5 mm means scrap or a major removal that can push the blade past its dimensional safety limit. The floor on any regrind is 0.254–0.381 mm of stock removal, because micro-fractures from running a blade past its sharpening window penetrate 0.25–0.40 mm below the bevel and will surface again if that layer is left in place (Maxtor Metal regrind-or-replace criteria for shear blades, retrieved 2026-08-27).
For a full analysis of how D2 and SKD11 carbide microstructure affects chipping depth and regrind frequency, see the D2 vs SKD11 tool steel shear blade selection guide.
Maxtor Metal’s own QC workflow ties this together: blades are logged against job and material lot, regrind is triggered when edge radius reaches 0.2 mm or burr height exceeds project tolerance, and every returned blade is re-verified for straightness under 0.02 mm/m, parallelism under 0.015 mm, and hardness across the full length before it goes back into rotation. These too are internal acceptance limits, set tighter than the general ISO 2768 / ISO 286 framework rather than drawn from a single published shear-blade standard. The point of the record is not the paperwork. It is knowing which of your four-edge reversible blades still has usable edges and which one is one bad cut away from a scrap decision.
FAQs:
Q : Qu'est-ce que la règle des 5–10 pour cent pour le jeu des lames de cisaille ?
R : Elle fixe le jeu entre les lames de cisaille à 5 % à 10 % de l'épaisseur du matériau. Pour de l'acier doux de 10 mm, cela représente 0,5 à 1,0 mm. La plage se resserre à mesure que la résistance à la traction augmente : l'aluminium tendre se situe près de la limite supérieure, tandis que l'acier inoxydable et l'AHSS (HSLA) se trouvent près de la limite inférieure. Traitez cette valeur comme un point de départ et confirmez-la par une coupe d'essai sur la coulée de matériau réelle.
Q : Le jeu des lames de cisaille s'entend-il par côté ou au total ?
R : Les deux conventions apparaissent dans les abaques publiés, et les confondre double votre jeu. Maxtor Metal spécifie ses 5–10 % recommandés comme jeu de lame par côté, de sorte qu'une coupe sur de l'acier doux de 10 mm s'effectue avec 0,5–1,0 mm par côté, soit 1–2 mm au total. Vérifiez quelle convention a été utilisée par le fabricant de votre machine avant de procéder au moindre réglage.
Q : Quel jeu dois-je régler pour de l'acier doux de 6 mm ?
R : Commencez entre 0,3 et 0,6 mm et vérifiez l'arête de coupe. Une arête propre et d'équerre avec une légère bande polie indique que vous êtes proche du bon réglage ; un arrondi prononcé ou une bavure irrémédiable signifie que le jeu est trop large. Mesurez la bavure plutôt que de la juger à l'œil nu.
Q : Puis-je utiliser le même jeu pour l'acier inoxydable et l'acier doux ?
R : Non. L'acier inoxydable, l'AHSS (HSLA) et les autres grades à plus haute résistance nécessitent un jeu plus serré, généralement vers la limite inférieure de la plage, car ils résistent à l'écoulement plastique et se fracturent plus tôt. Appliquer le jeu de l'acier doux sur de l'acier inoxydable entraîne des fissures sur les arêtes et une usure accélérée des lames.
Q : À quelle fréquence faut-il réaffûter une lame de cisaille ?
R : La hauteur des bavures est le déclencheur pratique : la pratique courante vise à maintenir la hauteur des bavures en dessous de 10 % de l'épaisseur du métal, et l'augmentation de la hauteur des bavures permet de suivre à la fois l'usure de l'outil et l'augmentation du jeu (Directives AHSS). Pour les aciers avancés à haute résistance (AHSS), la hauteur des bavures seule est un signal faible, de sorte que la qualité de l'arête de coupe constitue un meilleur indicateur. Le flux de travail de Maxtor Metal utilise un rayon d'arête de 0,2 mm ou une hauteur de bavure dépassant la tolérance du projet, selon la première de ces éventualités.
Q : Comment vérifier le parallelisme des lames de cisaille ?
R : Utilisez un comparateur à cadran sur base magnétique, en parcourant toute la longueur de la lame alors que la machine est verrouillée et hors tension. Maxtor Metal vérifie une rectitude inférieure à 0,02 mm/m et un parallélisme inférieur à 0,015 mm lors de la fabrication — il s'agit de limites d'acceptation internes basées sur le cadre général des tolérances ISO 2768 / ISO 286, constituant ainsi une référence judicieuse pour une machine en service plutôt qu'un chiffre exigé par chaque norme standard. Revérifiez après chaque réaffûtage ou changement de lame.
Q : Pourquoi ma cisaille produit-elle une double coupe ?
R : Une double coupe signifie généralement que le jeu est trop large par rapport à l'épaisseur, ce qui fait que le matériau fléchit dans l'espace et se fracture deux fois au lieu d'une. Cela peut également provenir d'une force de pressage (presse-tôle) insuffisante ou d'une lame qui a perdu son tranchant. Resserrez le jeu vers la limite inférieure de la plage et vérifiez la pression de serrage avant de rejeter la faute sur la lame.
Conclusion
Le jeu entre les lames de cisaille est une décision de réglage, pas un chiffre fixe, et la règle des 5–10 % constitue un point de départ défendable plutôt qu'une réponse universelle. Cette plage contrôle deux choses à la fois : l'importance de la zone polie et de la zone fracturée sur l'arête, ainsi que l'ampleur du tombé de bord (rollover) et des bavures laissés par la coupe. Réglez-le correctement et la face de coupe restera propre ; sortez de cette plage et vous ne ferez que troquer un défaut contre un autre.
Ce qui sépare un processus maîtrisé d'un processus fondé sur la chance, c'est la standardisation. Enregistrez le jeu défini pour chaque travail, notez la nuance et l'épaisseur du material pour lesquelles il a été configuré, et contrôlez l'état de l'arête à intervalles réguliers au lieu d'attendre une réclamation concernant les bavures. Suivez les cycles de réaffûtage par rapport à ces journaux de bord afin de pouvoir observer l'usure de l'arête avant qu'elle ne défaille. Considérez cela autant comme une question de flux de travail que comme une question de lame : la même valeur de jeu se comporte différemment d'une équipe à l'autre si personne ne la met par écrit.
Si vous installez une nouvelle cisaille ou standardisez une machine existante, examinez les spécifications de la lame par rapport à votre mélange de matériaux et à votre cycle de service avant de vous fixer sur une valeur. Lorsque le matériau ou l'application se situent en dehors des plages habituelles, consultez un ingénieur application pour savoir où votre processus doit s'écarter des normes et pourquoi.
