In precision manufacturing, the surface quality of a punch directly determines forming accuracy and mold service life. Our Carbide Mirror-Finished Polished Punch is specifically designed for high-precision stamping, drawing, and powder metallurgy industries. Using an ultra-fine grain carbide substrate with our exclusive mirror lapping process, it retains carbide's excellent hardness while achieving an ultimate mirror effect of Ra ≤ 0.02μm (nanolevel in some cases). This effectively solves common stamping issues such as material sticking, galling, and abrasive wear.
| Parameter Category | Item | Standard Specification / Range | Remarks |
|---|---|---|---|
| Substrate Material | Material Grade | YG6X, YG8, YG10X, YG15 | Can be recommended based on application |
| Density (g/cm³) | 14.5 - 15.0 | - | |
| Hardness (HRA) | 89.0 - 93.5 | Higher value = better wear resistance | |
| Bending Strength (N/mm²) | ≥ 1800 | Higher value = better toughness | |
| Machining Accuracy | Roundness | ≤ 0.0005 mm (0.5μm) | - |
| Straightness | ≤ 0.001 mm / 100mm | - | |
| Surface Quality | Mirror Grade | Ultra-mirror / Standard mirror / Rough ground | - |
| Surface Roughness (Ra) | ≤ 0.01μm - 0.02μm (Ultra-mirror) ≤ 0.05μm (Standard mirror) ≤ 0.1μm (Rough ground) |
Lower value = smoother surface | |
| Surface Luster | Bright silver / Mirror reflective effect | No tool marks, no drag lines | |
| Dimension Range | Diameter (mm) | 0.10 - 50.00 | 0.10-1.0mm is micro-diameter specialty |
| Overall Length (mm) | 20 - 300 | Recommended length-to-diameter ratio ≤ 15:1 | |
| Head Shape | Flat / Spherical (R-radius) / Tapered / Stepped / Custom profile | Fully customizable per drawing | |
| Key Characteristics | Coefficient of Friction | ≤ 0.1 (against steel, unlubricated) | Extremely low due to mirror finish |
| Thermal Expansion Coefficient | Approx. 4.5 - 5.5 * 10⁻⁶/°C | Approximately 1/2 that of steel | |
| Modulus of Elasticity (GPa) | 600 - 650 | Very high rigidity, resistant to deformation | |
| Usage Reference | Recommended Guide Bushing Clearance | 0.002 - 0.005 mm (per side) | Too little clearance may cause seizure |
| Max. Stamping Speed Reference | Application-dependent, up to 300-600 SPM | High-speed stamping requires rigid press |
