Definitions

  • the invention relates to a method for machining bearing or guide holes or correspondingly acting recesses according to the preamble of patent claim 1 and a device for carrying out the method.
  • DE 10 201 1 000 348 A1 discloses a method in which an inner circumferential surface of a bore of a workpiece is first of all finished by means of a radially adjustable fine boring head.
