Abstract:
A tool assembly for use on a machine having a spindle for driving a tool to machine cylindrical bores comprising:a removable tool body constructed in the form of a cylindrical shell having an internal axial bore, said shell having a plurality of channels formed in the outer periphery thereof, each channel having a slot constructed in the bottom thereof communicating with said internal axial bore, said body also having torque receiving means constructed therein;a plurality of abrasive assemblies mounted within the channels for radial movement with respect to the tool body;means mounted in the axial bore of the tool body to releasably support the tool body on the spindle, said mounting means including expander means in operative association with the abrasive assemblies through the channel slots to allow the adjustment of the radial position of said abrasive assemblies; andwherein said removable tool body is further constructed with an air gage integrally constructed therein for receiving a source of pressurized air and expelling said pressurized air outward from the outer periphery thereof, thereby enabling the sensing of variations in pressure at a remote location.
