Choosing the wrong grinding wheel can lead to poor performance, damage to tools, and even serious safety hazards. Here's a breakdown of common issues that arise when the grinding wheel does not match the application—and how to prevent them.

1. Poor Surface Finish, Burn Marks, or Inconsistent Grinding
🔎 Causes:
- Abrasive grain is too coarse, leaving deep scratches.
- Inappropriate grit size results in uneven surfaces.
- The wheel is too hard, causing high friction and burn marks on the workpiece.

✅ Solutions:
✔ Use a finer grit (Grit 150 or above) for smoother surface finishes.
✔ Choose an open-structure wheel to reduce heat buildup.
✔ Adjust the spindle speed to match the grinding wheel type.

2. Fast Wheel Wear or Cracking
🔎 Causes:
- Using a soft grinding wheel on hard metals.
- Incompatible bond type—for example, using Resinoid Bond in heavy-duty applications.
- Applying excessive pressure during grinding.

✅ Solutions:
✔ Match wheel hardness to the material—hard wheels for soft metals, soft wheels for hard metals.
✔ Ensure the RPM rating of the machine does not exceed the wheel’s limit.

3. Excessive Dust or Clogged Wheel Surface
🔎 Causes:
- Wheel structure is too dense, leading to swarf (debris) accumulation.
- Using the wrong wheel type on soft materials like aluminium.

✅ Solutions:
✔ Select a grinding wheel with an open structure for better chip clearance.
✔ Use a dressing tool regularly to clean and refresh the wheel surface.

4. Wheel Breakage or Damage During Use
🔎 Causes:
- Using the wrong type of grinding wheel or exceeding maximum RPM.
- The wheel had cracks or damage before use.
- Improper installation or over-tightening of the wheel.

✅ Solutions:
✔ Always inspect wheels for cracks or damage before use.
✔ Verify the machine’s speed does not exceed the wheel’s rated RPM.
✔ Install the wheel correctly and avoid over-tightening.

5. Slow Grinding and Low Productivity
🔎 Causes:
- Grit is too delicate for rough material removal.
- The wheel is too hard, preventing abrasive grains from fracturing and cutting effectively.

✅ Solutions:
✔ For rough grinding, choose a coarser grit (24–60).
✔ Use a grinding wheel with appropriate hardness for the material.

Summary: Choosing the Right Grinding Wheel Matters
✅ Match grit size to the level of surface finish required.
✅ Select abrasive type and bonding material based on the workpiece.
✅ Check wheel hardness and RPM compatibility before use.
✅ Maintain the wheel with regular dressing to ensure optimal performance.
