Claim 1
Independent Claim
333 words
A collet chuck comprising a tool mounting member provided with an elongated frusto-conical recess, said tool mounting member having an interior threaded portion, a passageway for introducing fluid into said member, an elongated tool having a fluid passageway located within the mounting member, an adjusting nut having a threaded exterior engaging the interior threaded portion of the tool mounting member, said adjusting nut having a fluid passage and being positioned contiguous to an end of the tool, a collet located within said frusto-conical recess, said collet having a tapered outer surface that is complimentary to the recess of said mounting member, said collet having a central bore of a size to receive a portion of said tool, said collet being provided with a plurality of radially disposed slots that permit the collet to be expanded and contracted, a coolant seal affixed to one end of said collet, said seal being of a sufficient size to sealingly engage the frusto-conical recess of said mounting member and said elongated tool, said coolant seal including an enlarged rouned toroidal portion and a flange of reduced size on one side of said toroidal portion, said flange being received snuggly in a circumferential recess that is provided in said end of the collet, an end of the flange abutting a shoulder on the collet and the flange having a generally circular formation, means on said mounting member for causing said collet to expand and contract to clampingly engage said tool whereby the fluid passes through the passageway of said mounting member and said tool but is prevented from passing around said tool by said collet and seal, said seal being made of a compressable material having memory characteristics, an adhesive for securing the seal to the end of the collet, said means for expanding and contrasting said collet comprising a retainer arranged in threaded engagement with said tool mounting member, an inner element arranged within said retainer, and a bearing interposed between said inner element and said retainer.
