Zusammenfassung |
AB |
[EN] The invention relates to a method for producing heat-resistant casting molds from molding sand containing binder, particularly for producing an inner contour of casting molds for prototypes, large volumes and deep grooves often being produced especially in the machining of molds for rapid production of prototypes from casting materials. To increase efficiency, in a first step blocks of molding material are produced whose dimensions correspond to a mold cavity depth typically of 300 mm to 400 mm. The inner contour of the mold is then produced oversized with spacing close to the contour of the inner wall of the mold cavity by means of a roughing tool ( 4 ) that has an effective cutting diameter of 12 mm to 35 mm. The mold cavity is then machined by fast milling away of the oversize material following the contour, with a finishing cutter ( 3 ) that has a diameter-to-length ratio between 1:10 and 1:30. |
