PURPOSE:To shorten blade grinding time of dies and to reduce the cost of grinding, by protruding the top part of each die from the upper surface of a casing by a specified height, and embedding a grinding plate in a region between the protruded top parts. CONSTITUTION:In a part of a machining region 24 of a casing 23, rectangular holes 25 are provided at a specified interval. A die 26 is coupled in each rectangular hole 25 so that the top part of the die is protruded from the upper surface of the casing 23 by a specified amount and the die can be freely attached and removed. The thickness of the top part of each protruded die 26 is set in consideration of the thickness of a body to be processed, quality of material and blade grinding allowance. On the casing 23 between the rectangular holes 25, blade grinding plates 28 are coupled between the dies 26. Since the blade grinding plates 28 are coupled between the neighboring dies 26, the grinding stone is directly contacted with the tip parts of the dies 26 when grinding is required, and the blade grinding can be quickly performed. |
