The cutting disc smokes and turns blue during use? You must avoid these wrong operations!

If the grinding wheel cutting disc heats up and turns blue, smokes, or even explodes during use, it is often caused by improper operation. The following are common errors and their solutions:

❌ Excessive pressure cutting → ✅ Use the tool's own gravity to cut naturally, and do not force it, which will cause the grinding wheel to heat up rapidly and wear faster.

❌ Continuous long-term cutting → ✅ Intermittent work and pay attention to rest time to prevent the grinding wheel from thermal expansion and loss of roundness or burning of the cutting seam.

❌ The cutting direction does not match the material → ✅ Keep the angle vertical during cutting to avoid bevel cutting and side pushing to ensure neat incisions and prevent edge explosion.

❌ Unfixed workpiece → ✅ Ensure that the cutting object is stable before work to prevent slipping and rebounding, which will affect personal safety.

❌ Not checking the wear of the cutting disc → ✅ Check the thickness and cracks regularly before and after use, and replace the cutting disc with severe wear or notches in time.

Using high-quality cutting discs is important, but reasonable operating specifications can better ensure construction efficiency and personal safety.
