Abstract
A pivot body (22) mounted on a machine bed (20) so as to be capable of swinging defines a lift axis (D) which extends transversely of its own pivot axis (A) and along which a reciprocating slide (24) is movable. Infeed of a saddle (26) on the reciprocating slide (24) can be effected along a spindle axis (E) transversely of the lift axis (D). A tool spindle (28) adapted to receive a tool (30) is supported on the saddle (26) so as to be driven in rotation about the spindle axis (E). Furthermore, a workpiece slide (42) is guided for traversing movement on the machine bed (20) and, together with a workpiece support (44), it defines a central plane (G) extending at right angles to the pivot axis (A). An advance finger (58) is adapted to be engaged intermittently with a respective one of the cutting teeth (12) of a workpiece (10) in order to advance the same. A common feeler (70) for determining the distance of the cutting teeth (12) from the workpiece support (44) as well as determining a measurable variable which reflects the condition of wear of the tool (30) or the advance finger (58) is movable from an inactive position into a measuring position near point (H) at which the pivot axi…
