Summary
Surface finish greatly affects carbide component friction, wear resistance and assembly fit. Our tungsten carbide OEM factory supplies multiple surface finishing choices for custom cemented carbide parts. This article introduces common treatments including fine grinding, mirror polishing, blasting and different coating options. We compare roughness level, application scenarios, cost impact and delivery notes for each surface treatment.
Full Article Structure
1. Introduction: Why Carbide Surface Finish Matters
Surface roughness directly influences wear resistance, friction coefficient and assembly performance of custom cemented carbide parts. Different working scenarios require different finishing levels. Our tungsten carbide OEM factory provides multiple surface treatments for custom carbide components to match various industrial application demands.
2. Main Surface Finishing Types We Provide
- Fine ground surface: Standard finish for most carbide inserts and wear parts
- Mirror polishing: Ultra-smooth surface for sealing, sliding friction applications
- Sandblasting: Matte surface for stress release and anti-glare requirement
- PVD / CVD coating: TiN, TiCN, TiAlN coating to boost wear resistance
3. Surface Finish Comparison Table
| Finish Type | Typical Ra Roughness | Common Application |
|---|---|---|
| Fine Grinding | Ra 0.2 ~ 0.8 μm | General cutting, wear-resistant carbide parts |
| Mirror Polishing | Ra ≤0.02 μm | Sliding pins, sealing components |
| Sandblasting | Ra 1.6 ~ 3.2 μm | Non-critical outer surface |
| PVD Coating | Coated on ground base surface | CNC cutting inserts, high wear tools |
4. How Surface Treatment Affects Quotation & Lead Time
Mirror polishing and coating need extra processing steps, adding production time and manufacturing cost. Simple ground finish has lower cost and faster turnaround. Our engineers will recommend suitable surface finish based on your actual working condition instead of blindly pursuing ultra-high smoothness.
5. FAQ for Tungsten Carbide Surface Finishing
Q1: Can we apply coating after carbide polishing?
Yes, but coating will slightly change final surface roughness, which we will note in technical specification.
Q2: Is mirror polishing always better for wear parts?
Not always. For some impact wear environments, a controlled matte ground surface performs better than mirror polish.
