First, the shutdown 1, the machine clean: the machine tool, fixtures, iron filings and other clean-up, external chip removal machine iron clean up; external sheet metal wipe clean, electric control box air conditioning, oil cooler filter clean ;
2, anti-rust treatment: A. Clean the workbench wipe clean, cast anti-rust oil; B. Spindle taper: wipe with a cloth sticky oil spindle taper hole C. Machine slow run all the way, lubricating rail. D. cutting fluid need to be replaced, the first priority to deal with rust, the machine needs to start work is to add cutting fluid.
3, power off: the X, Y-axis run to the middle, Z-axis back to zero, the total power switch off the machine and the transformer into the line switch, gas source;
4, rain and moisture: off the electrical box to do a good job of protection;
5, the machine is also good rodent control to prevent rats bite off the wire.
Second, the boot 1, check before boot: Check the machine's external environment, the electrical box with or without water and other anomalies, whether the deterioration of oil, knife cylinder, rail oiler, oil cooler and other oil is enough;
2, gradually boot: the first external power switch, check whether the voltage phase and phase is too low, without exception, open the machine power and observe whether there is an abnormal phenomenon, with or without leakage;
3, boot without alarm, do not perform any action, so that electrical components energized for 30 minutes;
4, slow moving: Check for interference, move the machine with the hand wheel, and pay attention to whether there is an abnormal phenomenon, and then perform the origin regression steps;
5, machine run-in: a long time automatic slow machine, and low-speed rotation of the spindle.
Third, the placement conditions 1, CNC machine tools should be placed in a constant temperature environment, the working environment temperature should be between 0 ~ 35 ℃. Avoid sunlight on the CNC machine tool directly affected by thermal radiation, to avoid the impact of moisture and airflow. In general, NC electronic control box with exhaust fan inside to maintain the electronic components, especially the CPU temperature is constant or small temperature changes. Extreme low temperatures or instabilities result in reduced life of control system components and increased failure. At the same time, the interior should be equipped with good lighting equipment.
2, in order to improve the accuracy of machining parts, reduce the deformation of the machine, if conditions permit, the CNC machine can be installed in the relatively confined, installation of air-conditioning plant.
3, the relative humidity of the working environment should be less than 75%, humidity increased, increased dust will bond in the integrated circuit board and lead to short circuit. Therefore, in the rain and snow to pay special attention to the environment, try to keep dry, you can also add a dust cover on the machine to prevent dust.
4, CNC machine tools should be installed in a place away from the liquid splash, and prevent leakage of the plant. Keep away from excessive dust and corrosive gases while away from vibrating equipment such as punching machines and equipment with electromagnetic interference.
On the eve of the Spring Festival holiday, we must stop the machine tool and place it. Finally, I wish you all a happy year of the monkey!
