1. Introduction: Common Doubts for Carbide Custom & OEM Buyers
Many industrial purchasers face uncertainty when sourcing custom cemented carbide parts. Questions about drawing review, material grade selection, lead time, minimum order quantity and inspection standards often slow down project progress. This FAQ guide collects the most frequent questions from our global customers about tungsten carbide custom machining and OEM orders, to help you make clear decisions before quotation.
2. What Is Tungsten Carbide Custom Machining & OEM Service
Carbide custom machining & OEM means we produce tungsten carbide parts strictly following your drawings, samples or technical requirements. It covers sintering, grinding, edge honing, polishing and other secondary processing. We do not sell only standard stock items; we tailor geometry, hardness, surface treatment to match your application scenarios.
3. Our Standard OEM Workflow for Custom Carbide Parts
- Receive your drawing / sample and technical requirement sheet
- Internal DFM review, grade suggestion and quotation
- Sample production for verification if required
- Mass production, in-process inspection and final QC check
- Packing and shipment with inspection report
4. VUILI Acceptable Drawing & Technical Document Requirements
We accept PDF, DWG, DXF, STEP and IGES drawing files. Drawings must mark key dimensions, tolerance, surface roughness, material grade and special surface treatment requirements. If you only have physical samples, we can arrange reverse measurement and drawing creation for you.
5. Machining Tolerance & Surface Finish Reference Table
| Processing Type | Typical Tolerance | Surface Roughness Ra |
|---|---|---|
| As-sintered blank | ±0.05 ~ ±0.15 mm | Ra 1.6 ~ Ra 3.2 μm |
| Precision surface grinding | ±0.01 ~ ±0.03 mm | Ra 0.4 ~ Ra 0.8 μm |
| Fine polishing | ±0.005 mm | Ra 0.05 ~ Ra 0.2 μm |
| Edge honing / passivation | Micro radius control, no bulk dimension change | Depends on honing specification |
6. Core FAQs for Tungsten Carbide OEM & Custom Machining
Q1: What is your MOQ for custom carbide OEM parts?
MOQ depends on part structure. Simple blanks support small trial orders; complex shaped parts have higher minimum quantity. We support sample order for performance testing.
Q2: Can you suggest suitable carbide grade for my working condition?
Yes, share your workpiece material, impact load, wear requirement and temperature, our engineer will recommend matching cemented carbide grade.
Q3: How long is the lead time for custom carbide OEM?
Samples usually take 7–15 working days, mass production lead time 15–30 working days, subject to complexity and order quantity.
