Large Round Slitting Blade
Big circular blades concentrate all the hard problems: mass that must stay balanced, an edge that must stay parallel across a wide diameter, and heat treatment that must reach uniformly through a thick cross-section. We build these discs the slow way – stress-relieved blanks, full-surface grinding and verified balance – because at rewinding speed, small defects become loud vibration.
The payoff is a blade that runs quietly, tracks without wander, and keeps cutting fabric, nonwoven, paper and film cleanly for a long service life between regrinds.
Diameters, bores and edge geometries are made to your drawing; send the old blade dimensions or a photo with measurements and we will quote within 24 hours.

Key Advantages
01Stable, Quiet Running
Balanced, parallel-ground discs rotate without vibration – critical on wide rewind stands.
02Edge True Across the Diameter
Full-face grinding keeps the cutting line straight from center to rim.
03Uniform Hardness
Heat treatment penetrates the thick section, so the edge wears evenly instead of softening early.
04Clean Cuts on Bulky Webs
Handles fabric, nonwoven, kraft paper and heavy film without snagging or fray.
05Long Regrind Life
Generous blade thickness leaves metal for multiple regrinds over the disc lifetime.
06OEM & ODM Service
Large diameters and special bores produced to drawing with inspection reports.

FAQ
What is the largest diameter you produce?
We produce large custom discs – send your diameter and thickness and we will confirm feasibility and price.
Can the blade be balanced for high speed?
Yes – balance and runout are checked before dispatch; tell us your machine speed and we meet the spec.
Which material for textile cutting?
Alloy steel covers most textiles; carbide helps with glass-fiber or mineral-filled nonwovens that wear steel quickly.
Do you provide spare edge geometry for regrinding?
Yes – we can supply the profile drawing with your order so your grinder can restore the exact edge.
