Document Type and Number:
Japanese Patent JP4467192
Kind Code:
B2
Abstract:
The invention relates to a device for fracture-separating a workpiece comprising several ring-shaped workpiece sections which are aligned axially one behind the other. The device comprises at least one expansion device which can be introduced axially into a borehole, formed in each ring-shaped workpiece section and has at least one expansion element that can be expanded in at least two axial expansion areas which lie at a distance from each other in the axial direction. The expansion device is provided with an integrated expansion control device which interacts with the expansion element for controlling a variable position and/or a variable expansion distance and/or a variable expansion period and/or a variable expansion sequence of at least the two expansion areas.
