In the past, we processed the large-diameter rubber washer by clamping a round wooden board on the three-claw self-centering chuck of the lathe, and cutting the square rubber sheet larger than the outer diameter of the washer with the nail or nail to the end of the board. On the top, it is cut with a special turning tool made of waste hand saw blade. This method wastes waste. Later, we designed and manufactured a cutting tool as shown in the figure. The rubber gasket was cut on the drill bed, and it was not necessary to cut the material into square before cutting. After years of practice, it is very convenient and practical.
