5 Grinding Considerations for Improving Surface Finish

Finishing touches on your machined pieces can be the difference maker between getting the job or not being considered for future work. Ideally, the specification for particular finish will be detailed, so any ambiguity or guessing is left out of consideration. Grinding process offers several ways through which you can arrive at desired finish. You can adjust parameters of the machine, size of the wheel grit and even the way you deliver the coolant. Overall maintenance of the machine is also an important factor for the quality of your work.

Key Takeaways:

  • Adjusting key parameters, such as wheel speed and depth of cut, is the easiest way to improve a part’s? surface finish.
  • Reducing either the dressing depth or the dress traverse speed is another option.
  • Other actions to consider are selecting the correct grit size and ensuring sufficient coolant application.

“If the goal is to improve the current surface finish from 20 microinch Ra to 17 microinch Ra, then simply increasing the wheel speed and/or reducing the feed rate slightly might be sufficient.”
