1 located and supported radially and axially by rotor upper end 37 by way of insert concave surface 44 mating with rotor convex surface 43 see fig7 a the final embodiment of the rotary support device allows an end user to adjust each cutting insert 1 in the field after fully manufacturing the cutting tool on which one or more rotary support devices are attached an example of this embodiment is shown in fig8 as an extension of the embodiment of fig7 a the main difference from the previous embodiments fig7 a is that housing 26 stator is extended axially in the direction opposite rotor upper end 37 integrated into the housing lower end 71 stator lower end is wedge interface surface 72 that is at a wedge angle 73 wedge interface surface 72 is not visible in cross section but is indicated with a heavy dashed line relative to being normal to rotor axis 36 wedge angle 73 is generally without limitation in the range of 1 to 20 degrees a larger wedge angle 73 will provide a larger range of adjustment but also generally reduces the resolution of adjustment actuation below and mating with wedge interface surface 72 is adjustment wedge 74 having stator interface surface 75 at substantially the same opposing wedge angle 73 so that it mates with wedge interface surface 72 as indicated in fig8 this embodiment is best achieved by.
