Frequently Asked Questions (FAQs) ♦ Dressing and Grinding Tools
The wheel is loaded and it's burning parts. What can I do?
Try increasing the traverse rate of the dressing tool. If you are using a single point; check to see if the point has worn, if so return it for reset or replace it. If you are using a particle dresser; check to see if there is any wear in the diamond section. New diamonds should be exposed, matrix should not be loaded, and diamonds should not appear flat and shiny. If you are using a rotary dresser, contact us or return for evaluation.
The wheel is not giving the required surface finish. What could be the problem?
Be sure the dressing tool is rigid in its holder. Slow down traverse rate of tool. If you are using a new single point tool, the finish will continuously improve as you wear the diamond. If you are using a particle dresser, consider going to a finer grit. If you are using a rotary dresser, contact us or return for evaluation.
The tool life of the dressing tool is shorter than it used to be. How can I resolve this?
Make sure the tool is rigid in the holder. Try rotating a single point tool to extend the life. Check to see if your process has changed. Is the material the same, are the grinding wheels and coolant the same, has any thing changed in your cycle. The slightest change can impact the life of the dresser and needs to be evaluated. If every thing has remained the same contact us for assistance.
What are the differences between electroplated and brazed tools?
Electroplated tools offer a mechanical bond holding the diamond or Cubic Boron Nitride (CBN) to the substrate. This works roughly the same as an iceberg; two thirds of the particle is buried below the bond and one third of the particle is exposed. Electroplated tools tend to hold tighter tolerances, and can provide better finishes.
Brazed tools offer a chemical bond holding the diamond or CBN to the substrate. This bond takes place at the base of the particle and allows for maximum particle exposure. Brazed tools offer aggressive removal rates, are free cutting, and longer lasting. Braze alloys have multiple features, they can be more abrasion resistant, more impact resistant, and offer a stronger bond than the same electroplated tools.
Both tools can be stripped and recoated.
Can you braze CBN?
Yes, you can. Bruce Diamond offers DAC and General Electric CBN material.
Should I use an electroplated or a brazed product?
Sometimes these tools are interchangeable but typically one is better suited for the application. Our sales engineers will be happy to evaluate your application to determine which product is best.
