METHOD AND DEVICE FOR PRODUCING A FRICTION BEARING OR A PART THEREOF, AND FRICTION BEARING OR PART THEREOF

摘要

According to a method for producing a friction bearing or a part, particularly half thereof, while machining the entire width of an inner surface both the radial extension and also the advance in the axial direction of at least one tool are changed during machining. A device for machining friction bearings or parts, particularly halves thereof, has a spindle and at least one cutting tool (14), the radial extension and advance of which can be changed during machining. In a friction bearing or part, particularly half thereof, slots or grooves are formed running in the peripheral direction, the depth and centre distance of which are designed to be larger in at least one axial edge area than in an axial central area.
