Here's how to estimate die clearance required for punching steel and aluminium.

Free online calculator for calculating required clearance for stamping punches and die buttons.

2025年1月6日 · Calculate punch and die clearance for mild steel, aluminum, copper, stainless steel, and more. Help optimize clearance to prevent burrs and fatigue.

The proper and safe clearance between the punch and the die will be different based on the size of hole you are punching, the material thickness, and the material hardness. Use this tool to help determine the correct die size based on the suggested minimal die clearance. Also See Our Punch Tonnage Calculator

2024年11月20日 · Punch and die clearance refers to the intentional gap or distance between the cutting edge of the punch and the cutting edge of the die in metal punching operations. This clearance is expressed as a percentage of the material thickness per side and is a critical parameter in the metal forming process.

2024年12月3日 · Achieving clean and precise cuts while maintaining tooling requires an understanding of punch and die clearance. This article explores what punch and die clearance (clearance) is, why it matters, and how to determine the …

Punch-to-die clearance (Δ) is the space between the cutting edge of the punch and the cutting edge of the die button, which is determined by the thickness and the type of material being punched. Optimizing the die clearance is one of the most important steps to punching success.

Die clearance, typically expressed as a percentage per side, is the distance between a punch’s cutting edge and a die button’s cutting edge. It’s the amount of extra space that’s needed to provide the leverage to shear and break the stock material to create a hole.

Using the correct die clearance for your punching operation is of critical important. Below are some typical die clearance measurements, as well as required tonnages for punching mild steel. Applying the wrong clearance can result in ruined product, damaged machinery and worse.
