What’s the Difference Between Resin Wheels and Diamond Wheels for Glass Polishing?

If you’ve read our previous posts, you know that diamond wheels and resin wheels both play essential roles in glass edge processing. But many factories still ask:

"Can’t I just use one wheel? Why do I need both?"

Let’s break this down, show the differences, and explain how pairing these tools correctly improves efficiency, quality, and tool lifespan.


1. Diamond Wheels: Shaping and Grinding

Diamond wheels are all about cutting power.

  • Made with natural or synthetic diamonds embedded in metal or resin bonds

  • Best for rough grinding, shaping, and removing material quickly

  • Durable and heat-resistant

Use diamond wheels for:

  • Removing sharp edges

  • Shaping thick panels

  • Preparing surfaces before polishing

Remember, forcing a diamond wheel to polish edges directly can lead to:

  • Uneven edges

  • Shorter wheel life

  • Overheating

That’s why they’re paired with resin wheels for finishing.


2. Resin Wheels: Polishing and Smooth Finishing

Resin wheels are softer and designed for fine polishing.

  • Remove micro-scratches

  • Provide smooth and glossy edges

  • Reduce edge chipping

  • Work best after diamond grinding

Applying too much pressure or skipping cooling can cause the resin wheel to wear prematurely — and that’s when customers notice quality drops.


3. How They Work Together

Here’s a simple workflow that most high-efficiency glass factories follow:

  1. Diamond Wheel Stage → rough grinding and shaping

  2. Resin Wheel Stage → smoothing and polishing

  3. Optional CNC polishing → final fine-tuning

Using both tools ensures:

  • Optimal edge clarity

  • Consistent gloss

  • Longer wheel lifespan

  • Lower overall costs

Without this combination, you risk uneven surfaces, higher waste, and increased downtime.


4. Tips for Selecting the Right Wheels

  • Diamond Wheel: choose grit, bond type, and wheel shape based on glass type and CNC machine specifications.

  • Resin Wheel: pick the correct bond and wheel hardness depending on the polishing stage and glass thickness.

  • Cooling System: clean, steady water flow is essential to protect both wheels.

  • Maintenance: dress wheels regularly and avoid excessive pressure to maximize efficiency.

Working with a professional supplier ensures you select the right combination for your production needs.


5. Why Jiangxi Jinlong Is Trusted

Since 2003, Jiangxi Jinlong has offered:

  • Diamond grinding wheels for glass

  • Resin polishing wheels

  • CNC tools for glass shaping

  • Complete sets for edge finishing

Factories worldwide rely on us because our products are engineered to work together, reduce tool wear, and provide a consistent polished finish.

As we always say: pairing the right diamond wheel with the right resin wheel is the key to high-quality glass processing.

Understanding the difference between diamond wheels and resin wheels is crucial.

  • One shapes, one polishes

  • One removes material fast, one smooths the surface

  • Used correctly, they save cost and boost efficiency

Choosing the right wheels from a reliable China manufacturer and supplier ensures smoother production, longer-lasting tools, and better glass edges.
