The normal use of gantry CNC drilling machines meets the following conditions: the power supply voltage fluctuation at the location of the machine tool is small, the ambient temperature is lower than 30 degrees Celsius, and the relative temperature is less than 80%.
- Standardized use of machine tools
When using the machine tool, the user is not allowed to arbitrarily change the parameters set by the manufacturer in the control system. The setting of these parameters is directly related to the dynamic characteristics of each component of the machine tool. Only the value of the gap compensation parameter can be adjusted according to the actual situation.
- Power supply requirements
Generally, gantry CNC drilling machines are installed in machining workshops. Not only does the ambient temperature change greatly and the use conditions are poor, but there are also many electromechanical equipment, resulting in large fluctuations in the power grid. Therefore, the location where the gantry CNC drilling machine is installed requires strict control of the power supply voltage. The power supply voltage fluctuation is within the allowable range and remains relatively stable. Otherwise, it will affect the normal operation of the CNC system.
- Environmental requirements
The location of the machine tool should be away from the vibration source, avoid the influence of direct sunlight and heat radiation, and avoid the influence of moisture and airflow. If there is a vibration source near the machine tool, an anti-vibration ditch should be set around the machine tool. Otherwise, it will directly affect the machining accuracy and stability of the machine tool, and will cause poor contact of electronic components, malfunctions, and affect the performance of the machine tool.
- Temperature conditions
The ambient temperature of the gantry CNC drilling machine is lower than 30 degrees Celsius, and the relative temperature is less than 80%. Generally speaking, an exhaust fan or air cooler is installed inside the CNC electric control box to keep the electronic components, especially the processor, at a constant working temperature or with a small temperature difference. Excessive temperature and humidity will reduce the life of the control system components and increase the number of failures. Temperature and humidity, increased dust will cause adhesion on the integrated circuit board and cause a short circuit.
Daily maintenance of the gantry CNC drilling machine even affects the service life of the machine tool.
- Check the automatic lubrication system of the spindle box.
Whether it works normally The headstock box is generally driven by gears and bearings through shafts to achieve various levels of transmission. Therefore, the oil circuit should be maintained, and the lubricating oil should be replaced regularly for new equipment. The wear of the gears in the new CNC machining center will produce iron smears to prevent dirt from entering the bearings and causing damage.
- Pay attention to check the cooling system
Check the liquid level and add oil or water in time. Replace and clean the oil and water when they are dirty. Cooling with coolant is essential. After a long time, there will be iron chips and coolant sediment in the water. These dirt should be cleaned in time to avoid clogging the water pump and water pipe.
- Clean and lubricate the guide rail surfaces
Machine tools with automatic lubrication systems should regularly check and clean the automatic lubrication system. Most of them use linear rails to achieve circular motion. The sliders in the linear rails are composed of hundreds of high-precision balls, so they cannot lack oil. In addition, the ball screws and nut of the X, Y, and Z axes of the machine tool are also composed of beads, and they cannot lack oil.
- Operators should clean the machine tools every day after get off work
Clean iron filings and wipe the coolant on the guide rails to prevent the guide rails from rusting. Wipe the machine clean with a rag when you get off work. To avoid rusting.
- Check whether the cooling fan in the electrical cabinet is working properly
Whether the air duct filter is blocked and clean the attached dust. For gantry CNC drilling machines, the electrical system of the machine is particularly important. Check the electrical cabinet for dust regularly. Check whether the electrical components are damaged, and check whether the fan and air conditioner of the distribution cabinet are operating normally.
- Pay attention to check the tightness of the guide rail strips and adjust the gap
After the gantry CNC drilling machine has been used for a period of time, due to normal wear, the gap between the strip and the mother-of-pearl should be adjusted frequently to determine the accuracy of the machine tool.
