Title:
DEVICE FOR CUTTING BAR-SHAPED OR TUBULAR WORKPIECES
Document Type and Number:
WIPO Patent Application WO2007137561
Kind Code:
B1
Abstract:
The invention relates to a device for cutting bar-shaped or tubular workpieces (1, 27), for example, a stripper. According to the invention, the tools (7, 26, 44, 46) are initially advanced by means of a relative rotational movement between a tool holder (3, 25, 45) which supports the tools (7, 26, 44, 46) and an advancing sleeve (4, 24, 47). The tool holder (3, 25, 45) and the advancing sleeve (4, 24, 47) are driven by means of toothed wheels (19, 18) which are arranged on the same drive shaft (17) and which comprise a helical gearing oriented in the opposite direction. An axial displacement of the drive shaft (17) produces a relative rotation between the tool holder (3, 25, 45) and the advancing sleeve (4, 24, 47). The invention also relates to milling cutters (26, 44) used as tools.
