<p>#CMT# #/CMT# The expandable reamer (1) has a base body (3), a ring section (R), cutting edge (13,15) which is geometrically defined and provided on the outer surface of the ring section. An adjustment device (21) works on the ring section from inside, has an adjustment screw (23) that adjust the radial position of a cutting edge. The adjustment device is arranged in a cavity (7) provided in the base body of the expandable reamer and has a conical or round outer surface (49). #CMT#USE : #/CMT# Expandable reamer. #CMT#ADVANTAGE : #/CMT# The adjustment device works on the ring section from inside, has adjustment screw that adjust the radial position of a cutting edge, and hence enable the accurate adjustment of the radius by making the thread accurately concentric to the axle center of the extension reamer. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional front view of expandable reamer. 1 : Expandable reamer 3 : Base body 7 : Cavity 13,15 : Cutting edge 21 : Adjustment device 23 : Adjustment screw 25 : Adjustment sleeve 49 : Round outer surface R : Ring section.</p> |
