0.7 mm Technical Clearance: Cutting Geometry and Sheet Thickness

The 0.7 mm clearance in a Ø23.5 mm die is optimally dimensioned for working with carbon steel sheet thicknesses of approximately 3.5 mm to 4.5 mm (applying the technical rule of 15–20% of the material thickness). Proper clearance prevents premature wear caused by friction between the punch and the die wall, drastically reduces the tonnage required by the machine, and avoids the formation of excessive burrs or conical deformation of the punched hole.

Technical Advantages

• Universal Standard No. 6: Fully compatible with the die holders used in the most common mechanical and hydraulic punching machines on the market (Geka, Peddinghaus, Mubea, Sunrise, etc.).

• High-Toughness, High-Hardness Tool Steel: Resists continuous lateral compressive stress and impact without deformation at the die opening.

• Slug Clearance and Relief: The lower channel is precision-ground with a relief taper to ensure the punched-out scrap (slug) falls away smoothly and rapidly, without jamming.

• data-path-to-node="7,3,0">Precision Fit and Centering: Precision-ground seat that ensures ideal alignment with the punch, preventing breakage caused by misalignment.

Technical Product Specifications

• Product Reference: M6R2420.

• Material Compatibility: Structural steel sheet (S235, S275, S355), stainless steel, galvanized sheet, and aluminum alloys.

• Clearance Selection: For thinner sheet metal (e.g., 1.5–2 mm), dies with smaller clearance (0.2–0.4 mm) are recommended; For thicknesses of 3.5 to 4.5 mm, the 0.7 mm clearance of die Ref. M6R2420 is the ideal configuration.

• Recommended Maintenance: Keep the die housing and base free of metal shavings and debris before securing the locking set screw, ensuring that the top surface remains flat and parallel.
