摘要： A circulating tool for cutting of workpieces including a carrier element that bears at least one cutter blade insert in an exactly positioned manner. A device is provided for adjusting the position of the insert relative to the carrier element and a clamping device is provided using a clamping claw, with which the insert can be fixed in the adjusted position relative to the carrier element in that the clamping claw presses the insert flat against a support surface. In order to be able to use indexable inserts of any form without providing weakening openings and to obtain the greatest possible measure of free space for configuring the tool and shaving removal with a space-saving configuration of the adjusting and clamping apparatus, the insert is accommodated in a pocket of the clamping claw and the support surface is directly constructed on the carrier element.

摘要： Valve seats are machined at the end of an axially deep, narrow cavity of a workpiece having an axially clampable surface within the cavity adjacent one or more valve seats. The method comprehends: (a) supporting a rotary driven spindle assembly of sufficient length to extend through the axial extent of the cavity and reach the valve seat, the spindle carrying a cutting tool at its extremity, the support being in a nonrotatable housing effective to fit closely to the interior of the cavity (within a tolerance of 0.01 inches) and effective to move along the axis of the cavity to bring the cutting tool into machining contact with the valve seats; (b) securing a radially rigid but axially resilient diaphragm to the end of the housing, the diaphram extending transversely across the interior of the cavity; (c) afer inserting the housing and spindle into the cavity so that the cutting tool is proximate the valve seat but out of contact therewith, axially clamping a portion, of the diaphragm remote from the spindle, against the axially clampable surface; and (d) moving the rotary driven spindle assembly axially toward the valve seat to conduct machining contact of the cutting tool therewith, the axially resilient diaphragm providing accurate supporting alignment for the tool under even high speed machining conditions.
