ABSTRACT:
A boring and turning mill, comprising a nonrotatable tool ram, a rotationally drivable tool spindle in the tool ram, an auxiliary head which can be attached to the tool ram in a nonrotatable manner, two work slides arranged in opposition to each other and displaceable and movable in a radially adjustable manner in the auxiliary head, each slide having a respective tool receptacle, and a drive connection to the slides for effecting a radial infeed movement of the work slides, between the tool spindle and the work slides. The drive connection is a threaded spindle which engages threads on the work slides, so that axial movement of the threaded spindle causes radial movement of the work slides.
