In the world of hard, brittle materials, the edge is everything.
A ceramic tile with a chipped edge is rejected
A glass mirror with a rough edge is unsafe
A magnetic component with an uneven edge won't fit
Edge finishing – chamfering, beveling, and corner rounding – is not just cosmetic. It's functional.
It prevents chipping. It improves handling. It ensures proper fit. It enhances safety.
But grinding edges on hard, brittle materials is challenging. Standard abrasives cause chipping, generate heat, and wear out quickly.
The solution? Electroplated diamond bevel / edge Grinding Wheels.
In this article, we'll explain why diamond is the only choice for edge finishing on ceramics, glass, and magnetic materials – and how the right wheel delivers perfect edges every time.
Ceramics, glass, and magnetic materials are difficult to grind.
| Material | Hardness | Grinding Challenge |
|---|---|---|
| Ceramics | Mohs 7-9 | Very hard – wears abrasives quickly |
| Glass | Mohs 5-7 | Brittle – prone to chipping |
| Magnetic materials (ferrite) | High | Hard and abrasive – difficult to cut |
| Hard stones | Mohs 6-9 | Abrasive – wears tools rapidly |
| Problem | Cause | Result |
|---|---|---|
| Chipping | Blunt abrasive or too much pressure | Scrapped parts |
| Cracking | Heat buildup | Damaged workpiece |
| Rough edge | Wrong grit or dull tool | Poor quality finish |
| Short tool life | Wrong abrasive | High cost per part |
| Requirement | Why |
|---|---|
| Clean, chip-free edges | No chipping – parts pass quality inspection |
| Consistent angle | Uniform chamfer – proper fit and function |
| Smooth surface | Safe handling – no sharp edges |
| Efficient processing | Fast cycle times – high productivity |
Diamond is the only abrasive that can effectively grind hard, brittle materials without chipping or cracking.
| Abrasive | Ceramics | Glass | Magnetic Materials | Reason |
|---|---|---|---|---|
| Diamond | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | Hardest – cuts cleanly |
| CBN | ⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐ | Not as effective on non-ferrous |
| Silicon Carbide | ⭐⭐ | ⭐⭐⭐ | ⭐⭐ | Wears quickly |
| Alumina | ⭐ | ⭐⭐ | ⭐ | Not suitable |
| Feature | Benefit |
|---|---|
| Extreme hardness | Cuts through hard materials |
| Sharp cutting edges | Clean cuts – minimal chipping |
| Low friction | Less heat – prevents cracking |
| Long life | Consistent performance – lower cost |
Electroplated diamond is the ideal choice for edge finishing applications.
| Bond Type | Diamond Layer | Sharpness | Life |
