Abstract: A method for machine measurement for an NC processing machine is provided. The processing machine has a machine head, for example, a fork head and an associated mechanical and electrical spindle changing interface for holding a motor spindle. A laser interferometer with a beam generator and a beam detector is also provided and at least one measurement optic which interacts with the laser interferometer, for example, in the form of a reflector, and laser interference measurements, which are directed at a measurement optic, in particular distance measurements, carried out for machine measurement. The laser interferometer has an interface which corresponds to the spindle changing interface, and the laser interferometer is substituted for the motor spindle via the spindle changing interface for machine measurement, and is aligned by means of the machine axes for the laser interference measurements.

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.
