Abstract
PURPOSE: To facilitate opening of irregular shaped holes and flash removing of castings through the eutectic reaction of contact faces by forcing a knife-form or bar-form copper material into an aluminum material which has been heated to its eutectic temperature or more and its melting point or less.
CONSTITUTION: A copper knife 2 is forced into an aluminum base material 1 which has been heated partially or wholly to its eutectic temperature 548°C or more and to the melting point of aluminum material or less to caused eutecting melting at the contact faces of both materials and fusion-cut the materials. Also, holing is done in the similar manner by forcing a copper material 3 to the material. If the thermal deformation of the aluminum base material 1 is of problem, heating the material in such a manner that the eutectic temperature of more is reached by contacting between the copper material and aluminum material is equally well and it is also possible to perform continuous working by maintaining the copper material at a high temperature. In addition, similar working may be done as well even by making use of the heat after casting or forging.
