| 摘要 |
<p>The invention relates to a machine tool for the mechanical machining of workpieces, e.g. by means of deep drilling or milling, comprising a machining beam (3) on which a headstock (6) is guided, whose spindle shaft (9), rotatably mounted in a spindle sleeve (8), is provided with a clamping device for clamping in interchangeable tools, the front end of the machining beam (3) being assigned a chip separator (19) and a removable boring bush (18). In such a machine tool, in order to fix the spindle sleeve (8) better to the machining beam (3) during operation without a boring bush, the invention proposes that, at the front end of the machining beam (3), there be provided a supporting bearing for the spindle sleeve (8), which bearing is provided on the inner side thereof with conical supporting surfaces (20) for the spindle sleeve which, on the outer side thereof, is provided with matching conical mating supporting surfaces (21). Furthermore, the chip separator (19) with the boring bush (18) arranged therein and a sealing system is implemented as a removable, cartridge-like housing, which can be inserted into the supporting bearing (17) from the side facing away from the spindle sleeve (8) and can be fixed there by a quick-release lock.</p> |
