摘要:
In a multi-axis machine tool comprising a first slide way (2a) and a second slide way (2b) set apart one from the other and extending parallel along a longitudinal axis (X), a machining station (3) delimited laterally by the slide ways (2a, 2b) , a cross member (4) presenting opposite ends (4a, 4b) each coupled to a respective slide way (2a, 2b), and a machining head (5) mounted to the cross member (4) and positionable over the machining station (3), at least the cross member (4) is fashioned from a low thermal expansion material.
摘要:
A multi-axis machine tool presents a gantry (2) positioned over a bed (3) equipped with a machining station (4) in which to position a workpiece (100), a moving beam (8) associated slidably with the gantry (2), aligned on a horizontal direction (X) and translatable in a vertical direction (Z), a carriage (9) associated slidably with the moving beam (8) and traversable in the horizontal direction (X), and a tool holder (10) mounted to the carriage (9). The tool holder (10) is mounted direct to the carriage (9), making no use of quills or telescopic arms, with freedom to rotate relative to the carriage about two positioning axes (C, D).

摘要:
A toolhead (1) for use on a multi-axis machine tool consists of a support assembly (2) equipped with a pivoting spindle (3) designed to accept a removable tool-holder (4), and centred on a machining axis (J) about which a tool (U) clamped to the tool-holder (4) can be driven in rotation. Also forming part of the toolhead (1) is a depth stop (9) affording an active surface (10) substantially transverse to the machining axis (J) and positionable against a surface (S) of a workpiece (P). The depth stop (9) is mounted to the support assembly (2) and capable of movement along the machining axis (J) between a first position, distanced from the spindle (3), and a second position of proximity to the spindle (3). Transducers (12) incorporated into the toolhead (1) are able to sense the position of the active surface (10) relative to the support assembly (2), and thus used to control the depth to which the workpiece (P) is penetrated by the tool (U).
摘要:
A machine tool (1) equipped with a supporting body (5) and at least one tool-holder spindle (6), rotatable about a respective axis (A1), also has a built-in dust extraction device (8) comprising an extractor hood (9) located in close proximity to the spindle (6) and presenting a suction port (10) positionable near to a machining area (11), so as to extract chips and dust generated in the course of machining operations; the hood (9) is capable of movement along a direction (D1) parallel to the axis (A1) of rotation, extended and retracted by the action of respective translating members (19) operating in conjunction with sensors (34) able to read the profile of a workpiece (7), in such a way that the suction port (10) can be positioned to best advantage.
