Embodiments of the present invention relate to a method and machine tool for machining a workpiece on the machine tool comprising at least 5 axes with a tool by using an NC program, the machine tool comprising a clamp for clamping a workpiece and a work spindle including a tool holder for holding a workpiece. The workpiece is clamped on the tool holder of the work spindle of the machine tool, the tool is clamped in the clamp of the machine tool, and the workpiece clamped in the tool holder of the work spindle is controlled in a program-controlled manner in relation to the tool clamped in the clamp for removing material from the workpiece.

A silent knife-grabbing apparatus includes a stationary disc, a rotary bar, and two locking units each including a latch, a lever unit, and two pushers. The latch is movable between a releasing position to place a first end thereof substantially out of a space of a clasp of the rotary bar and a locking position to place the first end in the space. The lever unit is movable between a folded position to place the latch in the releasing position and an extended position to place the latch in the locking position. A first end of the first pusher normally contacts the stationary disc so that a second end of the first pusher places the lever unit in the folded position. An end of the second pusher places the lever unit in the extended position when the upper end of the first pusher enters a recess of the stationary disc.

An auto tools change with space allowance for tool rejection of spindle includes an arm seat, an arm shaft, a tools change arm, a flat cam, and a driving arm, while the flat cam has a driving groove for driving the driving arm to swing and thus facilitates the tool clamping and tool unclamping. Therein, the driving arm has a tool clamping section having an allowance groove, a first transition section, a tool unclamping section, and a second transition section. Therefore, a larger width of the allowance groove is provided on the driving groove, thereby offering a sliding space for the tools change arm. Thus, a space allowance is produced during tool pushing process, thereby not only preventing the main shaft and the tool from being damaged, but also preventing the tools change arm from deformation.

A method and machine tool for machining a workpiece on the machine tool comprising at least 5 axes with a tool by using an NC program, the machine tool comprising a clamping means for clamping a workpiece and a work spindle including a tool holding means for holding a workpiece, where the workpiece is clamped on the tool holding means of the work spindle of the machine tool, the tool is clamped in the clamping means of the machine tool, and the workpiece clamped in the tool holding means of the work spindle is controlled in a program-controlled manner in relation to the tool clamped in the clamping means for removing material from the workpiece.
摘要:
A tool, magazine (11) for accommodating a plurality of tools (T) comprising a first tool housing portion (17) and second tool housing portions (19, 21, 23) in which a plate-like member having a plurality of tool receiving holes (17a, 17b) and tool receiving recesses (19b, 21b, 23b) formed thereto and each of the tool receiving holes and the tool receiving recesses has at least three supporting members having a convex portion which engages with a V-shape trench of a tool, and a tool transporting means (25) so disposed to face a back surface of the first and second tool housing portions for transporting the tool to/from the first and second tool housing portions from/to a tool exchange position (P), wherein the second tool housing portions are disposed rearwardly offset with respect to the first tool housing portion.
摘要:
The invention relates to a machine comprising a mechanical guide element (2a, 2b) for guiding the displacement of a first (3a, 3b) and a second device (4a, 4b). Said machine comprises a first drive device (5a, 5b, 10a) for displacing the first device (3a, 3b) along the guide element (2a, 2b), and a second drive device (6a, 6b, 10b) for displacing the second device (4a, 4b) along the same guide element (2a, 2b) as the first device (3a, 3b). The mechanical construction of a machine is simplified due to said invention.
