Abstract:
A method for lengthening a machining travel of a machine tool comprising a tool-carrying ram which provides tool gripping, exchange, guidance, driving and moving along three axes X, Y and Z, the three axes forming an orthogonal spatial system of axes and Z being a longitudinal axis of the machine-tool, movement of the tool-carrying ram being provided by linear motors, said method comprising the step of combining with the machining movements of the tool-carrying ram along one of the three axes, at least one simultaneous movement of a part to be machined parallel to a rotational axis of the tool-carrying ram and one of the three axes by synchronizing relative travels and speeds of the part to be machined with respect to those of the tool-carrying ram, wherein a first cover made of a first material is provided around the part to be machined and a second cover made of a second material is provided around the machine tool and first cover, wherein the first material is different from the second material.
