BORING SYSTEM FOR ITEMS WITH VARIOUS GEOMETRIES

摘要

There is disclosed a boring system (2), preferably for circular, elliptic or plane items (4). The boring system (2) includes a drive unit (6) with a boring member (8), the drive unit (6) being secured in a holding element (10) which may be displaced radially in against and away from the item (4), respectively. The boring system (2) includes further contact members (12, 14) which during use of the boring system (2) bear on the item (4). The contact members (12, 14) are provided in such a way and with such mutual spacing that will enable moving the boring member (8) in against the item (4) via an area delimited by the contact members (12, 14) while the contact members (12, 14) are simultaneously bearing on the item (4). The holding member (10) is displaceably mounted on one or more displacement means (16) on which the holding member (10) can be displaced radially in against and away from the item (4), respectively.
