Claim 1
Independent Claim
227 words
In a machine tool having tool support structure and a spindle axis, the combination comprising a tool carrier arranged to be mounted on said tool support structure, a tool holder arranged to be supported and located by said tool carrier in a predetermined position thereon, said tool holder being arranged to hold a tool in an adjustably preset position relative thereto, said tool carrier being provided with means defining an aperture in which said tool holder is supported and located, the means defining said aperture including two angularly inclined locating surfaces, arranged to extend parallel to the spindle axis of the machine, said tool holder having corresponding seating surfaces for being clamped against said locating surfaces of the tool carrier, and clamping means for releasably holding the tool holder with its seating surfaces in engagement with the respective locating surfaces of the tool carrier, said angularly inclined locating surfaces being positioned at accurately known distances from the machine spindle axis and the tool holder and tool carrier being provided with corresponding engaging abutment surfaces so as to determine the position of the tool holder along an axis parallel to the machine spindle axis in the operative position of the tool carrier, whereby said tool holder and associated tool can be accurately positioned relative to the machine spindle axis using the locating and abutment surfaces as reference data.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
125 words
A tool carrier arranged to be mounted on a machine Tool, the carrier having two locating surfaces for engagement with corresponding seating surfaces formed on a tool holder, the locating surfaces being angularly inclined relative to one another and arranged so that in the operative position of the tool carrier the locating surfaces extend parallel to the spindle axis of the machine tool, said locating surfaces being formed in an aperture of the tool carrier, and clamping means being provided on the tool carrier for releasably holding the tool holder with its seating surfaces in engagement with the respective locating surfaces, said clamping means being in the form of a screw-operated wedge device mounted with its screw axis parallel to the axis of the aperture.
Claim 4
Dependent Claim
125 words
A tool carrier arranged to be mounted on a machine Tool, the carrier having two locating surfaces for engagement with corresponding seating surfaces formed on a tool holder, the locating surfaces being angularly inclined relative to one another and arranged so that in the operative position of the tool carrier the locating surfaces extend parallel to the spindle axis of the machine tool, said locating surfaces being formed in an aperture of the tool carrier, and clamping means being provided on the tool carrier for releasably holding the tool holder with its seating surfaces in engagement with the respective locating surfaces, said clamping means being in the form of a screw-operated wedge device mounted with its screw axis parallel to the axis of the aperture.
Claim 5
Dependent Claim
31 words
A machine tool according to claim 1 wherein the clamping means is in the form of a screw mounted in the carrier and arranged to be engageable with the tool holder.
Claim 6
Dependent Claim
32 words
A machine tool according to claim 1 wherein the clamping means is in the form of a screw-operated wedge device mounted with its screw axis parallel to the axis of the aperture.
Claim 7
Dependent Claim
79 words
