Therefore, be sure to install and adjust carefully. After installation, shake the square head at the belt reel with your handle, and the console should be able to move.


Install the cross beam lifting cabinet and the side knife table equipment, install the cross beam lifting cabinet on the top of the column, accurately position it with nuts, and tighten the screws, and then put the side knife table slide against the right column guide rail. At this time, the guide rail should be cleaned. , And coated with grease, then insert the outer strips, install the pins, and use hydraulic jacks or wooden squares to resist, and screw the side turret ball screw from the lifting chassis to tighten the side turret nut. Before this, the right cross beam The elevator nut should be crossed by the side knife table ball screw and put in, and then the cross beam ball screw shall be inserted into the elevator nut.


Install the crossbeam: clean the surface of the vertical column and the crossbeam and apply grease. Before this, adjust the elevator nut to the same height-to-width ratio, and then place the crossbeam against the column guide rail. , And connect with the elevator nut to make the rail on the crossbeam level, and install the clamping plate, pins and inserts. CNC gantry milling the nut above the ball screw to adjust the leveling accuracy of the beam.


For the installation and wiring of CNC gantry milling machine manufacturers, see "Instructions for Use of Electrical Equipment".

Start the drilling machine and install the operating table. Before starting the drilling machine, check whether the operation organizations and electrical equipment are complete and appropriate, and master the functions of the control buttons and joysticks. According to the CNC gantry milling accuracy table, check the accuracy of the bed again. After reaching the standard, press the "lubrication sign" to drip oil to each position. After starting the operating table transmission device, turn the commutation power switch with your hand to observe whether the transmission gear of the transmission system is running normally, and then clean the bed guide rails and the operating table guide rails, and then the operating table can be lifted.


(1) Start the machine tool to move the worktable, check whether the moving direction and the rotation of the motor are correct, and pay close attention to the lubrication of the worktable guide rails.


(2) Test feed movement: Before the test, adjust the gap of each sliding guide surface of the tool post, check the tightness of each sliding surface by hand cranking the tool post, and then inject oil into each sliding surface to start motorized feed. Before the test, the gear or the handle that is connected to the feed can be placed in the neutral position to observe whether the feed mechanism is operating normally, check whether there are obstructions, and then place each tool post in the horizontal and vertical feed state respectively. Motorized feed test.


(3) Test the lifting movement of the beam: Before starting, adjust the gap of each sliding guide surface, and loosen the screw to carry out the lifting movement test.


(4) After the test run is completed, check the accuracy and make adjustments item by item according to the qualification certificate. If necessary, the "T" groove of the countertop can be refined.
