What is a Vacuum Brazed Grinding Wheel?

◆A vacuum brazed grinding wheel is a revolutionary abrasive tool designed for extreme performance and efficiency. Unlike traditional electroplated or sintered tools, vacuum brazed wheels feature a single layer of high-quality diamond or CBN (Cubic Boron Nitride) grains permanently bonded to a steel core using a high-temperature, high-pressure process in a vacuum furnace.

This advanced manufacturing technique creates an incredibly strong metallurgical bond, resulting in a tool that is sharper, more aggressive, and far more durable than conventional options. At HIZAR, we pioneer this technology to provide stone fabricators and construction professionals with the most reliable tools on the market.

Key Advantages of Choosing HIZAR Vacuum Brazed Grinding Wheels

• Unmatched Cutting Speed: Experience up to 30% faster material removal compared to electroplated wheels, drastically reducing project time.

• Exceptional Tool Life: The strong bond prevents premature diamond loss, offering a significantly longer lifespan and a lower cost per linear foot.

• Cool & Smooth Operation: The efficient chip evacuation reduces heat buildup, minimizing the risk of material damage (like burning stone) and extending the tool's life.

• Versatility: Perfect for a wide range of materials, from hard granite and engineered stone to concrete and ferrous metals.

• Economic Efficiency: While the initial investment may be higher, the unparalleled longevity and performance lead to substantial long-term savings on tool replacement costs.

Applications: What Can You Use Them For?

HIZAR vacuum brazed wheels are the ideal choice for professionals in:

• Stone Fabrication: Shaping and grinding edges on granite, marble, quartzite, and engineered quartz countertops.

• Construction & Renovation: Leveling concrete joints, removing high spots, and preparing surfaces.

• Metalworking: Grinding welds, deburring, and stock removal on steel and other ferrous metals.

• General Industrial Use: Any application that requires aggressive, fast grinding with a smooth finish.

How to Choose the Right Vacuum Brazed Wheel? (A Quick Guide)

Selecting the correct tool is crucial for optimal results. Consider these factors:

1. Material to be Ground:

   • Granite/Quartzite: Choose a wheel with a robust bond and durable diamonds.

   • Marble/Engineered Stone: A wheel with a slightly less aggressive bond may provide a smoother finish.

   • Concrete: Look for a coarse grit size for rapid removal.

   • Metal: Ensure the wheel is specifically rated for steel or metalworking.

2. Grit Size:

   • Coarse Grit (e.g., 30/40#): For rapid material removal and shaping.

   • Medium Grit (e.g., 80/100#): For general purpose grinding and smoothing.

   • Fine Grit (e.g., 200#+): For final finishing and touch-ups.

3. Tool Specifications:

   • Diameter (e.g., 4", 5"): Must be compatible with your angle grinder or profiling machine.

   • Arbor Hole (e.g., 5/8"-11, M14): Must match the thread of your machine's spindle.

Frequently Asked Questions (FAQ)

Q1: Can I use a vacuum brazed wheel for wet grinding?
A: While primarily designed for dry grinding, some specific models can be used with water. Always check the product specifications or consult with us before use.

Q2: How do I know when the wheel is worn out?
A: The wheel will stop cutting effectively. Since it's a single-layer tool, it will be completely worn smooth and should be replaced.

Q3: Are they suitable for use on a standard angle grinder?
A: Absolutely! Most of our vacuum brazed wheels are designed to run at standard angle grinder speeds (up to 12,000 RPM).

Q4: How does vacuum brazing differ from electroplating?
A: Electroplating uses a thin nickel coating to hold diamonds, which can wear away quickly. Vacuum brazing creates a permanent metallic bond that holds each diamond crystal much more securely, resulting in longer life and faster cutting.
