Diamut CNC Tools Redressing Service

Diamut tooling is highly designed to achieve tolerances that are extremely tight. The tool redressing process requires extremely skilled operators using a sequence of precision, custom-engineered machines to match original tool profiles precisely.

Braxton-Bragg is offering a service to have your Diamut CNC Wheels redressed for $110.00 per each CNC Wheel by Diamut America. This way you know that the tools you get back are to the exact specifications as the originals. Before sending your CNC tools, please call us and make arrangements to receive a Return Goods Authorization Number (RGA#).


The Process In A Nutshell

  • Customer calls Braxton-Bragg Sales Representative and asks for CNC Tool Redressing Service
  • Braxton-Bragg emails the customer a shipping label with an RGA#
  • An order is created and the customer's account is billed $110.00 (per each tool)
  • Customer prints the shipping label and drops it off at any FedEx location for shipping
    (Please ensure proper packaging of the tools in box to prevent any damaged during shipping)
  • Diamut redresses the tooling and when finished, the tools are shipped back to the customer


The process from the time you make the call to us, to the time you get your tools back is about 3-4 weeks. If you have any questions, please contact your Braxton-Bragg Sales Representative.


Diamut CNC Tool Redressing


What Happens In 5 Steps To The Stone Tools During The Redressing Process?

1. Preparation - Any wheel that Diamut receives from a customer is first inspected, cleaned and analyzed.

2. Erosion - To redress finer wheels, Diamut uses a custom-engineered EDM (electric discharge machine). Its copper electrode, specially machined to fit the inverse of each profile, sits a millimeter away and creates an electrical arc that burns away the diamond on each worn wheel.

3. Grinding - This grinding process is used for diamond wheels that run in position 1. They have protruding diamonds that are bigger than the tolerance, so they don’t need electroerosion like finer wheels. When the wheel is mounted, the camera captures its wear conditions, and custom software optically compares it with a CAD drawing of the original profile. Additional readouts let a skilled operator reach a precise angle of accuracy. A diamond wheel is mounted on one side and a grinding wheel on the other. The material disappears as the wheel is machined, allowing for finer adjustments based on the CAD drawing.

4. Pumice Redress - Next the Pumice Grinder, another custom-made Diamut machine, goes to work. Wheels that have been burnt with an EDM or grinded must be touched up. Pumice is used to sharpen and polish them.

5. Inspection - This last inspection ensures quality of the final product. It includes a visual inspection and usage of an optical comparator to ensure the accuracy of each profile after the redressing process is completed.
