Precision YG15 Tungsten Carbide Punch Professional Manufacturing Solution for Polishing and Mining

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

• 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.
