  • Patent number: 10403519
    Abstract: A cutting blade for cutting a workpiece includes a base and a cutting edge fixed to a peripheral portion of the base. The cutting edge is formed by bonding a mixture of abrasive grains and photocatalyst particles with a binder. In cutting the workpiece by using the cutting blade, a cutting water is supplied to the cutting blade and light is applied to the cutting blade to excite the photocatalyst particles. The cutting water supplied to the cutting blade comes into contact with the photocatalyst particles excited, so that the cutting water is given an oxidizing power due to hydroxy radicals.

  • Patent number: 10160095
    Abstract: Dressing tool including a main body having a working surface covered with hard-material grains distributed on the main body. Recesses for accommodating the hard-material grains are created in the main body and then filled with an adhesive, the excess adhesive is removed across the main body, and thereafter the hard-material grains are flung onto the main body so that only the grains located in the recesses remain adherent to the working surface of the tool. The hard-material grains can then be bonded to the main body by a physical and/or chemical bond. Thus, a distribution of the grains over the working surface of the tool that can be precisely defined in advance is ensured.
