<p>The spindle of the unit, with pneumatic feed, is directly driven by a motor (12) or a by a flexible shaft (9). An interchangeable gear set (4) allows to appropriately select the number of revolutions of the tool: a plurality of gear sets (5, 6) are available as desired and simultaneously, these gear sets (5, 6) being axially connectable one into the other. The motor output side (11) is connectable to the machining unit directly or by at least one gear set (5, 6) or by a coupling device (8) for a flexible shaft (9). With a machining unit of this type it is possible to actuate separately and efficiently spindles.</p> |
