|---|---|
Very hard and wear-resistant (much more than regular steel)
Stays sharp after thousands of cuts
Reduces downtime for blade changes
Good for large-scale automated production
Stiff, so it won’t deform during heavy cutting
Tough and heat-resistant
Cheap and easy to process
Good for small to medium-batch, non-continuous trimming
Easy to sharpen
Small edge angle (15–20 degrees): Sharper, cuts rubber cleanly, no tearing/crushing, flat and burr-free cut
Large edge angle (25–30 degrees): Duller, uneven cuts, rubber deformation, rough surfaces
Small edge angle: Less contact with rubber, less friction and heat
Large edge angle: More contact, more friction and heat
Too much heat: Softens rubber, makes it stick to the blade, ruins the cut, wears the blade faster
Blades expand and deform when heated (even 0.01mm)
Changes edge angle and cutting path
Causes uneven cuts, bad burr removal, failed quality checks
Very important for OTR tire trimming
Repeated heating and cooling weakens the blade
Increases chipping, cracking, or dulling
Less heat = longer blade life, lower replacement costs
Turn off equipment and let blades cool after each shift
Use a soft brush/cloth to remove loose rubber residue
Wipe blades with a special cleaning solution (no harsh chemicals) to remove stuck rubber
Dry blades completely to prevent rust
Apply special lubricant regularly to reduce friction and rubber adhesion
Check blade edges weekly for dullness, chipping, or deformation
Make sure blades are aligned and mounted correctly (no gaps)
Replace or sharpen blades if cuts are uneven or residue is hard to remove
Most common type
Small diameter, fits rotary trimmers
Good for continuous, high-speed cutting
Ideal for large areas of rubber burrs
Custom edge design
For precise trimming of special patterns, corners, and irregular areas
Straight cutting edge
Good for precise linear trimming of tire edges and seams
Large, thick, high-hardness rubber
Need blades with: larger diameter, thicker structure, 20–25 degree edge angle
Tungsten Carbide is best (very wear-resistant)
Smaller, thinner rubber, more precise trimming needs
Need blades with: smaller diameter, 15–20 degree sharp edge angle, lightweight
Use M2 HSS or Tungsten Carbide (depends on production volume)
Use sharp, precise edges
Remove residual rubber quickly and cleanly
Leave a smooth surface that meets factory and retreading standards
Critical for the flash removal process
Used with robotic arms or dedicated trimmers
For high-speed, online batch trimming on automated lines
Trim edges and seams after tread retreading
Ensure quality of retreaded tires
