When it comes to precision grinding and polishing, the debate between resin bonded diamond wheels and metal bonded diamond wheels never seems to end. Both are designed for strength, durability, and cutting accuracy — but they’re not the same. So, why do so many glass processors and CNC factories prefer resin bonded diamond wheels? Let’s dive into the details.

1. What Makes Resin Bonded Diamond Wheels Unique?

A resin bonded diamond wheel uses a resin-based compound to hold the diamond abrasives together. This bond makes the wheel softer and more flexible compared to the metallic bond type.

Because of this flexibility, the wheel adapts better to delicate materials like glass, ceramics, and quartz, preventing chipping or cracking during grinding. It’s a huge plus for industries where surface quality is everything — like architectural glass, automotive glass, and mirror finishing.

In simple words, a resin bond wheel gives you that smooth finish without the stress marks.

2. Main Differences Between Resin and Metal Bond Diamond Wheels

Here’s a quick breakdown for better understanding:

As you can see, resin wheels are all about precision and surface quality, while metal ones focus on longevity and heavy-duty cutting.

3. When to Use Resin Bonded Diamond Wheels

If you’re processing glass panels, mirrors, or optical lenses, the resin bonded diamond wheel should be your go-to tool. Its ability to operate under low pressure and high precision makes it ideal for:

• Glass edge grinding

• Beveling and chamfering

• Fine polishing

• CNC cutting and shaping

It’s particularly effective in CNC glass cutting heads or automatic polishing lines, where smooth feed and temperature control are critical.

And honestly, if you’re tired of micro-cracks or burned edges — this wheel’s your best bet.

4. Advantages of Resin Bonded Diamond Wheels

Let’s get real — everyone wants efficiency without sacrificing quality.
That’s where resin wheels shine:

1. Cooler cutting temperature – Prevents overheating, which can distort glass edges.

2. High surface finish – Delivers a glossy, scratch-free look.

3. Easy to dress – Restores shape quickly with minimal downtime.

4. Reduced vibration – Ensures cleaner cuts during high-speed CNC grinding.

5. Affordable cost-performance ratio – Lower upfront cost than metal bond wheels.

These benefits make resin bonded diamond wheels the preferred choice for manufacturers who value precision over brute force.

5. Why Choose Jinlong Resin Bonded Diamond Wheels

At Shenzhen Jinlong New Material Technology Co., Ltd., we specialize in producing resin bonded diamond wheels tailored for glass processing and CNC grinding. Our products combine:

• Imported resin bonding materials for stable wear resistance.

• Strict quality control for consistent cutting performance.

• Custom grit options (from 100# to 3000#) for every grinding stage.

We’ve been serving global glass manufacturers and distributors for over 18 years — so we know what works and what doesn’t. Choosing Jinlong resin wheels means choosing precision, reliability, and long-lasting value.

Because, let’s face it, your tools should work as hard as you do.

If your goal is mirror-quality glass polishing or fine CNC edge grinding, the resin bonded diamond wheel will outperform the metal bond type in both finish and efficiency. Metal bond wheels still have their place for shaping and rough grinding — but for precision, resin is king.
