How to choose the right blade:
· Material Type:
For cardboard, foam rubber, cork, gasket materials, universal blades like E12, E18, E25, E28 are suitable.
For textile foils, felt, flock materials, specialized wedge blades E50, E70 are better.
For soft polyurethane foam panels, use longer blades E85, E87, or E92 designed for EOT modules.
For fibrous or textured materials like honeycomb cardboard or carbon fiber, wave cut blades W30, W38, W60 with serrated edges are ideal.
· Blade Size and Cutting Depth:
Smaller blades (E12, E18) are good for precision and thinner materials.
Larger blades (E25, E28, E85+) handle thicker or larger cutting depths.
· Cutting Angle and Edge:
Wedge blades with different angles (30°, 50°, 70°) are designed for specific materials and cutting styles.
Wave cut blades have serrated edges for cutting tough or textured materials efficiently.
· Machine Compatibility:
Ensure the blade shank diameter matches your CNC tangential cutting module (usually 6 mm with Weldon surface).
Summary
· For general-purpose cutting of cardboard, foam, cork, choose E12, E18, E25, or E28 depending on desired cutting edge length.
· For specialized cutting of foils and textiles, choose E30, E50, or E70 based on material thickness and type.
· For soft foam panels, use E85, E87, or E92.
· For textured or tough materials like honeycomb cardboard or carbon fiber, select W30, W38, or W60 wave cut blades based on material hardness and thickness.
This approach ensures you select the blade that best fits your material and cutting requirements for optimal performance and blade life
