Description

Zund Z20 S3, G3, And D3 Flatbed Digital Cutting Systems Tin Coated Oscillating Carbide Knife Blades

Zund Z20 Flatbed Digital Cutting Systems Tin Coated Oscillating Carbide Knife Blades

Zund Z20 is a specialized, fine-pointed oscillating tungsten carbide knife blade designed for Zund S3, G3, and D3 digital flatbed cutting systems equipped with Electric Oscillating Tools (EOT/EOT-250) or Pneumatic Oscillating Tools (POT). Adding a Titanium Nitride (TiN) coating boosts durability and edge life for high-demand, high-frequency cutting.

Why Choose TiN-Coated Z20 Blades?
Minimal Overcut: The fine pointed geometry provides exceptionally sharp steering agility, making it ideal for cutting intricate shapes and tight inner radii without over-cutting adjacent lines.

Reduced Friction & Heat: Titanium Nitride creates a slippery, low-friction surface barrier that prevents gummy adhesives, soft foam, or rubber from sticking to the flat side of the blade during rapid stroke oscillation.

Extended Service Life: TiN coating increases surface hardness (up to ~2800 HV), allowing the cutting edge to resist dulling 2× to 3× longer than standard uncoated carbide when cutting mildly abrasive substrates like corrugated board or dense felt.

Primary Material Applications
Packaging & Board: Corrugated cardboard, solid folding carton, honeycomb board.
Foams & Gaskets: PE/PUR foam board, soft rubber, gasket sheets, and magnetic foils.
Plastics & Textiles: Corrugated plastic (twinwall PP), polyester fabrics, felt, and synthetic leathers.
