Key Specifications
Engineering Detail
A 610 mm blade spinning at high RPM will warp if not properly tensioned. We CNC-tension and micro-grind every log saw blade to ≤0.15 mm lateral runout, ensuring it cuts perfectly straight without oscillating and crushing the fragile cardboard core.
D2 and Cr12MoV blades heat-treated to HRC 58–60. This specific hardness range responds cleanly to continuous CBN grinding wheels without loading or glazing them, maintaining a razor edge and protecting your sharpening equipment.
Friction generates heat and explosive paper dust. Hard Chrome or Teflon (PTFE) coated blades lower the coefficient of friction, yielding pristine cut edges on premium 3-ply kitchen towel logs and extending Mean Time Between sharpening cycles.
[ Knowledge Base ]
Core crushing is primarily caused by excessive blade wobble (lateral runout) or a dull cutting edge. When lateral runout exceeds 0.20 mm, the blade physically beats against the core rather than slicing it. Our blades are tension-leveled and CMM-verified to ≤0.15 mm lateral runout. Also verify that your in-line CBN sharpening stones are correctly aligned and actively dressing the blade on every cycle.
Dust is generated when a high-friction blade tears tissue fibers instead of shearing them. We engineer a shallow bevel angle (15°–25°) combined with a mirror-polished face (Ra ≤0.2 μm). For maximum dust reduction, upgrade to our Teflon (PTFE) coated blades, which drastically lower friction and allow the blade to glide through the log with minimal fiber displacement.
Yes. The standard Ø68.26 mm (+0.05 mm) bore fits Fabio Perini and PCMC Forte/Elite directly. The Ø82.55 mm bore covers Casmatic and Kimberly-Clark-licensed OEM platforms. We hold OEM blueprints for Gambini and Bretting and supply guaranteed drop-in replacement tooling.
Log saws use synchronized CBN (Cubic Boron Nitride) stones to hone the blade continuously during operation. If the blade material is too hard or soft, it will load or glaze the stones, rendering them ineffective. Our D2 blades heat-treated to HRC 58–60 shed micro-chips cleanly without clogging your CBN wheels.
We manufacture tissue log saw blades up to Ø1200 mm for large-format industrial wiper and jumbo roll (JRT) production lines. These require our large-format vacuum heat treatment furnaces and CNC grinding equipment. Standard lead time is 10 working days from drawing sign-off.
Direct manufacturer. We forge, grind, and quality-inspect every blade in-house under ISO 9001:2015 certification. You communicate directly with the production engineers who made your blades — no reseller markup.
Yes. We supply matched sets of CBN sharpening stones engineered for our log saw blades, ensuring correct grinding angle, bond hardness, and abrasive grit for maximum blade life and minimum stone wear.
Sureay is ISO 9001:2015 certified. Every shipment includes a Rockwell HRC hardness test report, a CMM dimensional inspection record, and a heat treatment batch certificate. Mill certificates and full material traceability reports are available on request.
