Summary
This article lists the full technical specification checklist you need to provide when submitting custom carbide component drawings. Clear specs help suppliers deliver accurate quotation and shorten sample development cycle.
Full Article Structure
1. Why Complete Technical Specs Matter for Custom Carbide
Custom carbide components cover wear parts, cutting inserts, forming dies and anti-slip studs. Missing technical details often lead to different interpretation between buyer and factory. Standardized technical specs help our engineers evaluate manufacturability and quote accurately.
2. Core Specification Checklist for Drawings
- Material grade, hardness and density requirement
- All dimension tolerances, geometric tolerances and datum marks
- Surface roughness, polishing or coating requirement
- Edge condition: sharp, hone, chamfer or radius
- Inspection method, acceptance criteria and required test report
- Packaging, marking and batch traceability requirement
3. Common Specification Classification Table
| Spec Category | Standard Level | High Precision Level |
|---|---|---|
| Surface Roughness Ra | Ra0.8 ~ Ra1.6 | Ra0.2 ~ Ra0.4 |
| Hardness | Within grade range | Narrow hardness window |
| Marking | Laser marking optional | Fixed font, position and depth |
| Inspection | Spot check | 100% key dimension check |
4. How to Handle Special Functional Requirements
- Impact resistance: Confirm dynamic load, recommend higher cobalt grade
- Corrosion resistance: Special anti-corrosion treatment or tailored binder
- High temperature working: Optimize grade and coating system
- Magnetic requirement: Specify non-magnetic carbide if needed
5. FAQ: Spec Revision and Sample Validation
Q1: Can we adjust specs after sample approval?
Yes, revised drawing and specs will trigger new quotation and re-evaluation of lead time.
Q2: What if I do not know the exact hardness requirement?
Share your working condition, we can suggest suitable grade and hardness range for your reference.
6. Summary
Complete technical specifications attached to your drawing is the foundation of stable OEM carbide orders. Avoid vague description such as “good quality” or “hard enough”. Write measurable standards so both sides follow the same acceptance rule.
