This product is specifically designed for high-precision metal stamping, precision electronic connector punching, and high-wear applications. It utilizes ultra-fine grain cemented carbide substrate combined with a front-end flat (D-cut or flat positioning) design. This structure ensures ultra-high hardness at the cutting edge while solving the common problem of traditional round punches rotating under heavy loads, which leads to edge chipping. The flat design provides precise angular orientation, ensuring consistent punching direction in multi-station dies.
The unique front-end flat structure (single flat or double symmetrical flats), combined with the flat clamping surface, completely eliminates punch rotation under high-frequency impact. This is critical for irregular hole punching (such as rectangular, oval, or complex shapes), ensuring a contour repeatability of up to ±0.002mm.
Using gradient sintering technology, the punch maintains good fracture toughness (KIC) on the inside, avoiding brittle fracture caused by lateral forces. This is especially beneficial for the thin-walled "flat step" transition zone.
| Parameter | Standard Range / Options | Remarks / Tolerance |
|---|---|---|
| Flat Angle Type | Single Parallel Flat / 90° Vertical Flat / 180° Symmetrical Double Flat | Flatness ≤ 0.002 mm |
| Cutting Edge Shape | Round, Shaped (Square/Oval/Toothed) | Mirror polished / Sharp edge with micro-radius |
| Grade Material | YG6X, YG8, YG10X, YG15, KD20 (Imported) | Selected based on stamping material |
| Surface Coating | TiN (Gold) / AlTiN (Bronze) / No Coating | Reduces friction coefficient to 0.4 |
| Concentricity | ≤ 0.003 mm | Between shank and cutting edge |
