Analysis of the difference between of ZUND Z20 Z21 Z22 Z23 Z28 Z29 cutting machine systems tungsten carbide blades
Tungsten carbide blades for Zund cutting systems (Z20, Z21, Z22, Z23, Z28, Z29) differ primarily in cutting geometry, depth capacity, and material compatibility. These oscillating blades are designed for precision cutting in Zund G3, S3, L3, and D3 series digital cutters using Electric/Pneumatic Oscillating Tools (EOT/POT). Below is a detailed analysis:

Design and Performance
o Both share an 84° cutting angle, but the Z21 offers greater depth (17.2 mm vs 14.3 mm) for thicker materials like leather hides and magnetic foil.
o The Z21’s finer geometry minimizes overcut, making it ideal for intricate patterns.
2. Z22 Distinctive Features
o Unique 63°/79° cutting angle for precision in rigid materials like corrugated plastic and rubber.
o Compatible with Esko and Summa systems, enhancing versatility.
3. Z23 Applications
o Designed for industrial-grade cutting of composites and thick plastics, though exact depth specifications are unlisted
o Limited data available, but thickness matches Z21/Z23 (0.63 mm). Likely optimized for niche materials or tool configurations.
Tool Compatibility
· Shared Compatibility: All blades work with Zund EOT/POT tools
· Material-Specific Pairing:
o Z20/Z21: Foam board, folding carton, polyester fabric.
o Z22: Corrugated plastic, rubber, sandblast film.
o Z23: Thicker composites (e.g., polycarbonates).
Material Considerations
· High-Density Materials: Z21 and Z23 are preferred for leather, polycarbonates, and industrial composites due to their deeper cut capacity
· Angled Cuts: Z22’s 63°/79° angle suits rigid materials requiring bevels or grooves
· Cost Efficiency: Z20 balances performance for mid-density materials like corrugated cardboard
For Z28/Z29, consult manufacturers directly for specifics, as public technical data is sparse. Prioritize Z21 for intricate designs or Z22 for angled cuts in rigid substrates.
