    摘要： In a machine tool or a processing method, a column base (12) is supported on a bed (11) movably in a horizontal direction, and a column (13) is installed vertically on the column base (12). A saddle (14) is supported on a side of the column (13) movably in a vertical direction, and a ram stock (15) is supported on the saddle (14) movably in a horizontal direction. A spindle (16) is rotatably supported by the ram stock (15), a damper (21) is provided on the ram stock (15), and an O-ring (22) is provided between the ram stock (15) and the damper (21), so that the O-ring (22) can be deformed by a pressing member (23). An NC device (24) can adjust a deformation degree of the O-ring (22) by the pressing member (23) depending on a mass of an attachment (17). Therefore, vibration of a tool can be effectively damped by changing a natural frequency according to replacement or movement of the attachment.

    摘要： A spindle head for machine tools includes a housing (16), a spindle (12) having a through-hole (12b) formed therein and a tapered portion (12c) at one end thereof for receiving a tool holder (8), a bearing means (14, 44) for supporting rotatably the spindle (12) in the housing (16), a draw-bar (30) placed in the through-hole (12b) of the spindle (12), a collet (36) connected to the draw-bar at its one end for holding the tool holder (8), and means (20, 28) for moving the spindle (12), the bearing means (14, 44) having a concave portion (14c). The spindle (12) has a convex portion (12a, 42a) corresponding in shape to the concave portion (14c). The concave portion (14c) of the bearing means (14, 44) cooperates with the convex portion (12a, 42a) of the spindle (12) so that the bearing means (14, 44) can support the spindle (12) in both radial and thrust directions.

    摘要： A device for positioning and locking turning, milling or other tool holders on to mobile slides with an internal spindle, comprising a first system (14) of conventional type for machining centres which is designed to lock tools (37) usually carried by this type of machine; the device also comprises two diametrically opposing levers external to the slide (10), which are hinged (31) to the slide (10) and each comprises two end teeth (32,33), of which the first (32) is opposite a projection (29) on the piston (28) of a hydraulic or pneumatic cylinder (23), and the second (33) is arranged to engage in a tool holder (43) of a lathe tool (42) in order to lock it; the locking condition occurs when the piston (28) carrying the projection (29) has moved under the action of elastic means (27) so as to press against the opposing tooth (32) of the lever (30), so rotating this latter (30) such as to cause its other tooth (33) to engage in the tool holder (43); the release condition occurs when the piston (28) carrying the projection (29) has moved against elastic means (27), so as to cause the opposing tooth (32) of the lever to abandon the projection (29) such that the lever (30), urged by its elastic means (35), rotates in order to disengage the second tooth (33) from the tool holder (43).

    摘要： The present disclosure discloses a complex machining turning center. In the complex machining turning center according to the present disclosure, a tool post 103 is moved on a bed 101 along an X-axis by a slide rest 104, a tailstock 105 is moved along a Z-axis direction, and a headstock 102 is moved in a C-axis direction, and the complex machining turning center includes: a B-axis swing movement unit 110 which allows the headstock 102 to swing along a B-axis on a plane coordinate formed by the X-axis and the Z-axis; and a Y-axis up/down movement unit 120 which allows the headstock 102 to be moved upward and downward along a Y-axis that crosses the X-axis and the Z-axis.
