Abstract: A tool support base and a tool post for cutting a casting, in which contact surfaces in sliding contact with both side plates are formed on both sides of the tool support base and the tool post. A cut recess is formed in the sliding contact surface so as to vertically extend in the surface. Deposit welding is applied to the cut recess and a ridge of weld deposit generally flush with the contact surface is formed by grinding means that makes the weld deposit, formed by the deposit welding, flush with the contact surface. The construction minimizes wear of the contact surface as much as possible, and even if particles of casting waste materials enter gaps between the tool support base and the tool post and the side plates, the construction can avoid wear by such particles.

Abstract: A production method for deburring die for castings utilizes a machining gap defined between an electrode of an EDM apparatus and a deburring die member or a cut member, feed control of the electrode and electric discharge machining effected by applying a pulse voltage between the electrode and a steel sheet or cut member. In this method, a prototype of castings is horizontally hung in the apparatus with either one side thereof serving as a model for the front side of the lower deburring die while a contour of the prototype is two-dimensionally detected based on the X- and Y-coordinates, the values of which are inputted in a control unit of the EDM apparatus. Based on the values, a lower deburring die hole symmetrical with the contour of the prototype is formed in the steel sheet thereby producing the lower deburring die and the cut member.
