Precision YG15 Tungsten Carbide Punch with HRA87 Hardness, ±0.002mm Tolerance, and Mirror Polishing for Industrial Applications

Precision YG15 Tungsten Carbide Punch Professional Manufacturing Solution

YG15 tungsten carbide punches utilize premium hard alloy material with 15% cobalt content, offering exceptional hardness (HRA87) and outstanding impact resistance. Our precision manufacturing process ensures dimensional accuracy within ±0.002mm and achieves mirror-like surface finish of Ra0.1, meeting the most demanding industrial applications.

Precision Manufacturing Process

1. Material Preparation Stage

• Uses high-purity WC powder (99.95% purity) with precise cobalt ratio
• Isostatic pressing ensures uniform material density
• Vacuum sintering controls grain growth for homogeneous fine-grained structure

2. Machining Stage

3. Ultra-Precision Finishing Stage

• Nano-level Lapping: Diamond compound with progressively finer grit (W40 to W0.5)
• Mirror Polishing: Fiber polishing wheel with diamond suspension for Ra0.1 finish
• Final Sizing: Real-time adjustment through online measurement feedback system

Key Technical Guarantees

Environmental Controls:

• Temperature-controlled workshop (20±1℃)
• Class 10,000 cleanroom environment
• Anti-vibration foundation (<2μm vibration amplitude)

Inspection System:

1. CMM (Accuracy: 0.5μm+L/200)
2. White light interferometer surface profiler
3. SEM microstructure analysis
4. X-ray residual stress testing

Material Certification

Tungsten carbide (WC) is an ultra-hard ceramic material composed of tungsten and carbon, renowned for its exceptional hardness, wear resistance, and chemical stability. Its chemical formula is WC, with a hexagonal crystal structure and a high density of 15.6–15.8 g/cm³—nearly twice that of steel. It has an extremely high melting point of 2,870°C, ensuring excellent thermal stability. In terms of hardness, tungsten carbide has a Mohs hardness of 8.5–9, approaching that of diamond, and a Vickers hardness of 1,700–2,400 HV, far exceeding high-speed steel. Additionally, its thermal conductivity is 110 W/(m·K), providing outstanding heat dissipation, and it exhibits strong chemical inertness, resisting most acids and alkalis—though it is susceptible to hydrofluoric-nitric acid mixtures.
