The wear-resistant evaluation of dental milling cutters based on cemented carbides

This work presents the evaluation of wear resistance of milling cutters. The subjects of this chapter were the milling tools commonly used in dental laboratory. Based on the results it was found, that the milling cutter during the cutting operation can easily become the destruction, resulting in the mass loss and in the first 10 hours of milling cutters work with high efficiency. It is suggested that after 10 hours of milling work, in order to ensure high standards of materials processing, milling cutters should be replaced by new one.
