Abstract
A machining assembly with a drive unit (10) detachably mountable to the feed module (30) and moveable along a guide track on a machine stand via the feed module. The feed module is provided with a feed gear wheel (33) configured for engagement with a cog track on the machine stand. An electric drive motor (12) for rotating a spindle (13) and an electric feed motor (16) for rotating the feed gear wheel are arranged in a housing (11) of the drive unit. The drive unit comprises a drive member, which is rotatable by the feed motor and which is operatively connectable to the feed gear wheel via a torque transmitting coupling mechanism (50) when the drive unit is mounted to the feed module so as to allow the feed gear wheel to be rotated under the effect of the feed motor when the drive unit is mounted to the feed module.
