In our recent blogs, we talked about how diamond wheels handle the heavy grinding while resin wheels take over the polishing stage. Many glass factories rely on this smooth workflow, but here’s the truth: even the best resin wheel won’t perform well if it’s used incorrectly.

A lot of customers ask us, “Why does my resin wheel wear out so fast?” or “Why is the polishing effect not as smooth as expected?” So today, let’s break down the five most common mistakes when using resin wheels—and more importantly, how to avoid them. And yeah, fixing these can instantly improve your polishing results.

1. Using a Resin Wheel for Heavy Grinding

This is the most common mistake.
A resin wheel is designed for fine polishing, not cutting or shaping. But many users push it too hard, expecting it to do the same job as a diamond wheel.

This leads to:

• Fast wear

• High heat

• Surface burning

• Poor polishing smoothness

If you skip the diamond wheel step and jump straight to resin polishing, the wheel will basically cry—well, you know what I mean.

Correct approach:
Use a diamond wheel for rough grinding, then use the resin wheel only for smoothing and finishing.

2. Applying Too Much Pressure

We talked about pressure control in previous blogs, and it matters just as much here.
Excessive pressure on a resin wheel causes uneven wear and reduces polishing quality.

Here’s the simple idea:
More pressure ≠ faster work
More pressure = more damage

Correct approach:
Maintain steady, gentle pressure. Let the wheel work naturally, not forcefully.

3. Ignoring Cooling Water Quality

Cooling water affects both diamond wheels and resin wheels, but resin wheels are more sensitive.
Dirty or insufficient water can cause:

• Clogged wheel surface

• Burning marks on glass

• Overheating

• Shorter wheel lifespan

And once a resin wheel overheats, its bonding structure weakens permanently — this is where things start gets bad.

Correct approach:
Make sure the water:

• Is clean

• Flows consistently

• Has stable pressure

A good water system extends resin wheel life significantly.

4. Polishing Glass Too Quickly

Sometimes production lines run fast to save time, but resin wheels need a stable polishing speed to produce a clean, smooth edge.

If the feed speed is too fast:

• The wheel cannot polish fully

• The glass edge becomes uneven

• You may see leftover grinding marks from the diamond wheel

And honestly, customers can see those marks immediately — not good for product quality.

Correct approach:
Slow down the polishing stage, even just a little.
A consistent speed results in a noticeably better finish.

5. Using the Wrong Resin Bond Formula

This connects closely to our earlier blog on choosing a Professional Diamond Wheel for Glass Processing.
The same logic applies here:
Different resin wheels are designed for different applications—tempered glass, furniture glass, automotive glass, ultra-clear glass, etc.

Using the wrong bond means:

• Wheel wears faster

• Polishing is harder

• Heat builds up

• Glossiness decreases

Not all resin wheels are the same, and choosing the correct bond is a huge part of efficiency.

Correct approach:
Work with a China supplier or manufacturer who can provide bonded wheels tailored for your machine speed, glass type, and required finish.

Resin wheels play a crucial role in the finishing stage of glass processing.
When used correctly, they help you achieve:

• Smooth edges

• High transparency

• Stable polishing results

• Longer tool lifespan

When used incorrectly, however, they wear out quickly and slow down your entire production line.

The good news?
Each of these mistakes is easy to fix — and once corrected, your polishing line will run much smoother.

If you want the best results, pair a diamond wheel for shaping with a resin wheel for polishing, just like we’ve discussed in previous posts. It’s a workflow that truly works.
