For manufacturers striving for precision and productivity in high-volume machining, the choice of grinding tools can make or break operational efficiency. At Henan Youde Superhard Tools Co., Ltd., we’ve engineered a new benchmark with our vacuum brazed diamond grinding wheels—specifically optimized for multi-axis automatic grinding machines used in cast iron processing.
Traditional electroplated diamond wheels suffer from poor bond strength, leading to premature diamond loss and inconsistent surface finish. In contrast, vacuum brazing uses a copper-based alloy (Cu–Sn) at temperatures between 750°C–850°C under controlled atmosphere conditions, creating a metallurgical bond that holds diamonds securely even under heavy load.
Our R&D data shows:
| Performance Metric | Electroplated Wheel | Vacuum Brazed Wheel |
|---|---|---|
| Diamond Retention Rate (%) | ~60% | >95% |
| Tool Life (hours) | ~12 hrs | ~40 hrs |
| Surface Finish (Ra μm) | 1.2–2.0 | 0.6–1.0 |
These numbers aren’t just impressive—they translate into real-world gains. One European automotive parts supplier reported a 3x increase in throughput after switching to our vacuum-brazed wheels on their CNC grinding lines, while reducing tool change downtime by over 60%.
Cast iron is notoriously abrasive and thermally sensitive—a challenge that demands both thermal stability and consistent cutting performance. Our wheels are tested across gray, ductile, and compacted graphite iron (CGI), delivering stable cutting forces and minimal heat generation due to superior diamond distribution and bonding integrity.
Available in diameters from 100mm to 400mm and customizable for specific machine configurations, these wheels support both standard and bespoke applications—from gear honing to cylinder bore finishing.
With growing demand for automation-driven manufacturing, especially in Asia and Europe, this technology is not just an upgrade—it’s a necessity for staying competitive.
Whether you're running a mid-sized job shop or a large-scale OEM, adopting vacuum brazed diamond technology means less waste, fewer interruptions, and more predictable results.
