(1) Work objects should be clamped with pressure plates, screws or special equipment. Do not use a normal wrench to add casing, so as to avoid slipping and hurting people.
(2) The tool must be clamped, otherwise it is not allowed to drive.
(3) Before the work, check the running condition of the transmission part of the machine tool and install the baffle of the machine tool to run.
(4) Milling various workpieces, the unique is the rough cutting, the initial should be slow cutting.
(5) When moving the table and the tool holder, loosen the constant screw first.
(6) When loading and unloading tools, use a copper hammer or a raft to lightly prevent the pieces from flying out of the wound.
(7) During cutting, the tool is not allowed to shift and adjust the tool to prevent the workpiece from being touched or measured.
2. Gantry milling structure: The portal milling machine includes a bed, a workbench mounted on the bed, and a numerical control circuit control system. The gantry milling machine bed is equipped with an X-axis guide gantry milling workbench that is fastened to the bed. The gantry frame is arranged on the movement spanning frame above the workbench, and the gantry frame further comprises: a gantry carriage, and the gantry carriage movement is clamped on the X-axis guide rail. The Z-axis guide rail is mounted on the gantry. The beam is provided with a Z-axis carriage, and the beam is moved and clamped on the Z-axis guide rail through the Z-axis carriage, and the Y-axis guide rail is further mounted on the beam. The milling device and the milling device of the gantry milling machine are mounted on the Y-axis guide rail, so that the gantry frame is subjected to three-dimensional space milling processing of X, Y and Z under the control of the numerical control circuit control system.
