A thermally insulated container (10) includes an inner container (11), and an outer container (14) surrounding the inner container (11) via a void (15). Each of the inner container (11) and the outer container (14) contains a fiber reinforced plastic prepared by impregnating a base material with a resin. The inner container (11) includes a first tubular container (13) and a second tubular container (22) each having an internal holder (23, 24) to reserve a refrigerant (16), and a refrigerant inlet tube (12) through which the refrigerant (16) is introduced. The holder (24) is in communication with the holder (23). The base material in each of a predetermined area of the second tubular container (22) and a predetermined area of the outer container (14) contains woven fabrics. The predetermined area of the outer container (14) further includes a honeycomb sheet.

The present invention is aimed at the mechanical industry sector and relates to a turning machine tool (1), suitable for machining delicate pieces of the casing type (B), which must be handled with care to avoid damage, scratches, dents, etc., comprising a substantially cylindrical body with a thin wall, a first end (B1) closed and a second end (B2) open so that said body is hollow. Said machine tool (1) comprises: a frame structure (2) for support and resting on the ground; feeding means of pieces to be machined and a mandrel (4) comprising a hole (5) for housing a piece to be machined and jaws (6) for gripping and holding said piece in position; first motor means (M1) adapted to rotate said mandrel; a first tool (7) suitable for machining a first end of said piece, and a second tool (8) suitable for machining a second end of said piece; means for unloading the machined pieces; a command and control unit (100). Said machine tool (1) is characterized in that said second tool (8) is placed on the opposite side of said first tool (7) with respect to said mandrel (4), so as to allow said machine tool (1) to simultaneously machine said first and second ends of the piece held by said single mandrel (4).
