Even brand-new grinding wheels should be trued before use to ensure the surface is concentric and aligned with the spindle, preventing vibration, chatter marks, and poor results. Truing improves accuracy, smooth operation, safety, and quality. Never assume a new wheel is perfectly true; small adjustments can significantly improve performance. Always follow safety guidelines when truing or adjusting wheels.
Yes. Even brand-new grinding wheels should be trued before use. Truing ensures the wheel’s surface is perfectly concentric and aligned with the spindle, which is critical for accuracy, smooth operation, and a quality finish.
Why is truing important?
- New wheels can be slightly off-center or unbalanced.
- An untrued wheel may cause vibration, chatter marks, and poor grinding results.
- Proper truing reduces the risk of injury by ensuring the wheel runs smoothly.
Key points to remember:
- Never assume a new wheel is perfectly true. Some wheels require more adjustment than others.
- If you notice a slight wobble, loosen the wheel and rotate it on the arbor. A small adjustment—such as a ¼ or ½ turn—can make a big difference.
- Always follow the safety guidelines in your machine’s manual when truing or adjusting wheels.
