Clamping apparatus for machine tool, material transfering apparatus and linear machining apparatus comprising the same, and three-dimensional linear machining apparatus

摘要

Holding the first and second elongate member gripping means (13, 39) and the second elongate member gripping means 39 is installed on the first the processing head than the elongate member gripping means (13) portion 32-side and, a second elongate member gripping means (39) has a through hole (14c), the elongate member 53 is possible through is formed. First and second elongate member holding means is provided to enable Ivan relatively accessible in the first direction. First by while holding the elongate member 53 by the elongate member gripping means (13), the access path to the second elongate member gripping means (39) direction, the elongated member 53 of the second elongate member gripping means 39 from protrudes by an arbitrary amount toward the processing head portion 32. By doing so, it executes the processing line 3d with respect to the elongate member 53 by the machining head (36). With respect to the elongate member by a free-form surface which can carry out a cutting process and so on in succession, thereby facilitating the production process.
