Your sharpening system ships with a wheel. When that wheel wears out, your customer has two choices: buy your OEM replacement, or find a generic alternative that “fits.” The difference between those two outcomes is whether your wheel is a commodity — or a precision component your customers trust. LIVTER’s diamond sharpening wheel OEM program builds the latter.
Dual-Quality Tier Program: Imported & Domestic
Not every sharpening system needs imported abrasive. LIVTER offers two distinct sharpening wheel tiers for OEM partners:
| Tier | Abrasive | Grain Tolerance | Hub | Label | Best For |
|---|---|---|---|---|---|
| Export (出口级) | Japanese-spec imported diamond | ±5μm | 3-spoke machined aluminum | 进口砂 + 出口级 | Premium sharpeners, pro-grade tools |
| Standard | Domestic diamond | Industry standard | Solid or spoked aluminum/steel | Standard marking | Value sharpeners, entry-level |
Custom Hub Engineering
The 3-spoke design is LIVTER’s standard, but OEM partners specify their own:
- Spoke Count: 3-spoke, 4-spoke, 5-spoke — balanced for your RPM range
- Cutout Geometry: Curved (centrifugal fan effect), straight, or custom profile
- Hub Material: 6061/7075 aluminum, stainless steel, or black phenolic
- Mounting Pattern: Central bore + 3-bolt (standard), 4-bolt, or custom
- Bore Size: 20mm standard, 12.7mm (1/2″), 15.875mm (5/8″), 25.4mm (1″), or custom
- Diameter Range: 80–150mm for sharpening wheels; 125–300mm for bench grinder wheels
- Branding: Laser-etched logos, 出口级/进口砂 tier markings, serialized QC tags
