Latest Patents

One of Tsutsuyama's key patents is a method for chamfering toothed gears. This method enables the lengthening of a tool's life by improving the chamfering process. The technique involves sequentially chamfering the line intersection portions between tooth flanks and end faces of the teeth with end cutting edges. A pitch Pb of the end cutting edges is set to five times a pitch Pa of the teeth. This configuration allows for a faster circumferential speed of the end cutting edges compared to the teeth, thereby reducing cutting resistance during the chamfering process. As a result, the life of the tool can be significantly extended.
