Abstract

Zur Erhöhung der Schnittleistung einer Teilschnittma­ schine ist der Schneidkopf (2) in eine Außenwalze (3) und eine in dieser konzentrisch geführte und längs verschiebliche Innenwalze (4) geteilt. Die Innenwalze (4) ist stirn- und umfangseitig mit Schaftmeißeln (9) bestückt und dient zur Herstellung einer Pilotbohrung, die auf den Durchmesser der Außenwalze (3) erweitert wird. Danach wird die Innenwalze (4) in die Außenwalze (3) zurückgezogen und der Strecken­ querschnitt nunmehr ausschließlich mit der Außenwalze (3) geschnitten. Da die Außenwalze (3) nur an ihrem Umfang schneidet, kann sie mit Rollenmeißeln (5) bestückt werden. Gegenüber Schaftmeißeln (9) lassen Rollenmeißel (5) wesentlich höhere Schnittleistungen zu und haben bedeu­ tend höhere Standzeiten. To increase the cutting performance of a partial cutting dimension machine is the cutting head (2) in an outer roller (3) and in this concentrically guided and longitudinally movable Inner roller (4) divided. The inner roller (4) is frontal and Equipped on the circumference with chisels (9) and is used for Production of a pilot hole based on the diameter of the Outer roller (3) is expanded. Then the inner roller (4) withdrawn into the outer roller (3) and stretching cross section now exclusively with the outer roller (3) cut. Since the outer roller (3) only on its circumference cuts, it can be equipped with roller chisels (5). Roller chisels (5) leave opposite chisels (9) much higher cutting performance and have meaning tend to have a longer service life.
