RECOVERY OF CUTTING CAPACITY OF WORN STEEL AND CARBIDE DENTAL BURS BY THEIR ELECTROEROSION TREATMENT
The purpose of this paper is to study experimentally how electroerosion treatment (modification) of aworn working surface of steel and hard-alloy dental burs affects the recovery of its cutting capacity. The key elements of the experimental research methods are described, including the description of a device for electro- erosive modification of the worn working surface of steel (XB5) and hard-alloy (ВК6М) burs, and a device for determining their cutting ability by the intensity of their cutting a textolite sample.
