If you’ve read our previous posts, you already know how diamond wheels and resin wheels work together for perfect glass edges. But in real CNC glass processing, choosing the right tool set can be tricky. Many factories struggle with questions like:

"Which diamond wheel should I pair with which resin wheel?"
"How do I optimize tool life and polishing quality?"

Let’s break it down step by step.

1. Identify Your Glass Type

The first step is simple but crucial. The type of glass you’re processing determines the wheel material, bond type, and grit size.

• Tempered glass → needs tough diamond wheels for rough shaping and a medium-hard resin wheel for polishing

• Ultra-clear or low-iron glass → requires peripheral or cup-shaped diamond wheels for minimal chipping, paired with soft resin wheels for a glossy finish

• Thick architectural panels → use metal bond diamond wheels for heavy grinding and medium-hard resin wheels for polishing

Matching the tool to the glass type ensures efficiency and prevents unnecessary wear.

2. Choose the Right Diamond Wheel Grit and Bond

As we mentioned in previous posts, the grit size and bond type of a diamond wheel matter a lot.

• Lower grit → faster material removal, rougher edges

• Higher grit → slower removal, smoother edges

• Metal bond → best for heavy grinding

• Resin bond → better for fine shaping

Tip: choose a combination that balances speed and edge quality. Too coarse and you’ll damage the glass; too fine and production slows down.

3. Pair With a Suitable Resin Wheel

Once the diamond wheel finishes rough shaping, a resin wheel comes in for polishing.

• Select the resin bond hardness based on polishing depth and glass thickness

• Ensure proper cooling to prevent overheating and reduce wear

• Remember: resin wheels can’t replace diamond wheels—they’re made for finishing, not heavy grinding

Correct pairing improves edge transparency and glossiness significantly.

4. Consider CNC Machine Specifications

Every CNC machine has different spindle speeds, feed rates, and pressure settings. Your tool set must match these conditions.

• High-speed spindles → wheels with balanced grit exposure

• Low-speed spindles → slightly harder resin wheels to maintain polishing effect

• Consistent pressure → reduces chipping and increases wheel life

Integrating the tool set with CNC parameters is key for optimal performance.

5. Work With a Reliable Manufacturer

This is where Jiangxi Jinlong stands out. We provide complete CNC glass tool solutions, including:

• Diamond grinding wheels

• Resin polishing wheels

• CNC glass cutting tools

• Peripheral and cup wheels for fine edges

Our products are engineered to work together, reduce downtime, and improve edge quality. Many factories trust us because we combine:

• 18+ years of experience in glass processing

• Stable diamond exposure

• Optimized resin bonds

• Tailored solutions for different CNC machines

Selecting the right tool set for CNC glass edge processing is more than picking a wheel. It’s about creating a workflow that pairs diamond and resin wheels perfectly.

Do it right, and you get:
✔ Smooth, transparent edges
✔ Longer wheel lifespan
✔ Stable production efficiency
✔ Lower overall costs

Skipping stages or mismatching tools leads to poor finish, high wear, and wasted time. Trust a professional China manufacturer and supplier to guide your selection — it saves headaches and money.
