Choosing the right grinding disc isn’t just about size—it’s about matching material, precision, and performance. At UHD Superhard Tools Co., Ltd., we’ve helped over 500 industrial clients across Europe, North America, and Southeast Asia optimize their machining processes by selecting the correct brazed diamond grinding disc diameter (100–180 mm) and shape (flat or curved). This guide breaks down how to match your workpiece material—like gray cast iron, stainless steel, or ceramic—with the ideal disc specifications for maximum efficiency and tool life.
Brazed diamond segments offer superior bonding strength compared to electroplated or sintered discs—especially under high-impact conditions. In real-world tests, UHD’s brazed discs show up to 40% longer wear life on stainless steel parts and 3x higher resistance to chipping when grinding ceramics. The key? A uniform bond between the diamond grit and metal matrix that maintains sharpness even at 1,200 RPM feed speeds.
| Material Type | Recommended Diameter | Shape Suggestion | Key Benefit |
|---|---|---|---|
| Gray Cast Iron | 125 mm | Flat | High cutting speed, low heat generation |
| Stainless Steel | 150 mm | Slightly Curved | Reduced edge burn, consistent finish |
| Ceramic / Glass | 100–130 mm | Custom Radius | Precision control, minimal micro-cracking |
A German automotive supplier was struggling with inconsistent surface finishes on stainless steel brake components. After switching from a generic 125 mm flat disc to our 150 mm curved brazed diamond disc, they saw:
These results weren’t luck—they came from understanding the material properties and choosing the right geometry. That’s why every UHD disc undergoes ISO 9001-certified quality checks before shipment, ensuring reliability across global production lines.
