Scratch Marks while grinding

Improving centreless grinding requires careful attention to blade material, wheel hardness, dressing techniques, and vibration control. Using softer materials like steel or aluminium bronze can enhance blade support, while adjusting wheel grades addresses surface issues like irregular marks and spiral lines.

Dressing strategies, such as slower traversing rates and frequent diamond adjustments, help avoid uneven lines, spiral marks, and other finish flaws. Controlling vibrations and maintaining a clean, properly balanced system—especially coolant and wheel conditions—are essential. Regularly inspecting and replacing components like diamonds and regulating wheels also ensures a smooth, consistent finish.
