A vacuum brazed diamond grinding wheel is a high-performance abrasive tool designed for efficient grinding of cast iron and other ferrous materials. Unlike electroplated wheels, this type uses a high-temperature brazing process to bond diamond grits to a steel core, ensuring superior grain retention and extended tool life.
Features:
✔ **Vacuum Brazing Technology** – Diamond abrasives are securely bonded using a high-strength alloy (e.g., silver or nickel-based) in a vacuum furnace, preventing oxidation and ensuring optimal adhesion.
✔ **High Material Removal Rate (MRR)** – Aggressive grinding with minimal heat buildup, ideal for hard and abrasive materials like **gray cast iron, ductile iron, and chilled iron**.
✔ **Open Structure** – Reduces clogging and improves chip evacuation, critical for cast iron’s graphite flakes.
✔ **Long Service Life** – Stronger bond than electroplated wheels, reducing grain loss and wear.
✔ **Customizable Grit & Shape** – Available in flat, cup, or dish shapes with grit sizes (#30–#200 for roughing, #200–#600 for finishing).

Customization:
Vacuum brazed diamond grinding wheels are a premium choice for industries requiring high-precision grinding of ultra-hard materials. Their superior bond strength and diamond retention make them cost-effective for high-volume or demanding applications. When selecting a wheel, prioritize material compatibility, grit size, and cooling methods to maximize performance and lifespan. Pair with appropriate machinery and safety protocols for optimal results.
If you need to customize, please provide the following information:
1. Dimensions, including outer diameter, aperture, thickness, width and thickness of abrasive layer;
2. Abrasive, abrasive sand particle and concentration;
3. Adhesive;
4. Wheel application;
5. Pictures and drawings of wheels;
We can then design and quote for you
