Abstract
A facing head is described comprising two slides which are arranged adjacent each other in a radial plane and on a tool adjustment for active force balancing. The slides are formed as two parallel connecting links (couplers) between two double-armed cranks of a parallel crank mechanism. On tool adjustment, the slides are moved simultaneously and oppositely to each other while they describe a part of a circular path. Guiding of the slides reduces the influence of the centrifugal force on the slide drive force. The cutting angles of tool cutting edges disposed on the slides, therefore, change only slightly on tool adjustment.
