Abstract
A process of making brazed monolayer abrasive tools wherein the braze alloy and abrasive particles are applied to the tool form and the weight of each material is monitored after each application step to determine the weight of each of these materials which is applied to the tool form to more precisely control the bond height and diamond concentration in the finished tool product. The weight of each material applied to the tool is compared to a predetermined target weight after the individual steps of applying the material. If the amount of either material applied to the tool falls outside selected limits of the weight target, the tool assembly may be rejected at that stage of the process. Only tools which successfully pass the comparison step are further processed and introduced to the fusion for step braze bonding the alloy and abrasive particles to the tool. This permits the tool components from rejected tools to be recovered and recycled if desired. Also disclosed is a method of using this weight monitoring process to fabricate tools having a known range of amounts of alloy and abrasive particles applied and testing the same to determine the most desirable weight target to be u…
