Title:
MACHINE TOOL ASSEMBLY
Document Type and Number:
WIPO Patent Application WO2003084711
Kind Code:
A3
Abstract:
A machine tool assembly having a base assembly movable relative to a support selectively a) oppositely parallel to a first line, and b) oppositely parallel to a second line that is orthogonal to the first line, and a first spindle headstock movable with the base assembly and having a central axis extending parallel to the first line and a working end. The machine tool assembly further includes a first turret assembly movable with the base assembly and having a first turret headstock and a first turret head that is movable around a first axis relative to the first turret headstock. The first turret head is movable selectively into first and second different angular positions around the first axis relative to the first turret headstock. The first turret head and first spindle headstock are movable relative to each other parallel to the first line in a manner that the first turret head can move up to and past the working end of the first spindle headstock without interference between the first spindle, headstock and first turret assembly with the first turret assembly and first spindle headstock in a first relative state. The first turret assembly and first spindle headstock interfere with each other as the first turret assembly and first spindle headstock are moved relative to each other parallel to the first line in a manner that the first turret head moves up to the working end of the first spindle headstock with the first turret assembly and first spindle headstock in a second relative state.
