At present, in the field of mechanical processing, NC bus processing machine has many advantages compared with traditional bus processing machine, so it is increasingly used. However, the equipment is a kind of equipment integrating mechanical, electrical, hydraulic, gas, microelectronics and other technologies. It is difficult to eliminate and maintain after faults occur. This requires the operator to pay attention to prevention when using the NC bus processing machine, so as to reduce the probability of failure and improve the utilization of the bus processing machine. What aspects should be checked before using the NC bus processing machine.
1、 Before use, the bus processing machine shall be placed in a relatively dust-free place with constant temperature and humidity according to the technical requirements of the NC bus processing machine for the installation and use environment. Although it is difficult to do so at present, it should be as close to this use environment as possible. In addition, when the bus processing machine is installed and used normally, pay attention to the following contents:
Before using the bus processing machine, check the bus processing machine, which can reduce the failure of the bus processing machine in the process of use and affect the production.
Before power on, check the appearance of the NC bus processing machine, electrical pipelines and some external auxiliary equipment for abnormalities. Especially for external auxiliary equipment: for pump stations with hydraulic system, observe whether the amount of hydraulic oil is sufficient; For those with air pressure system, regular drainage of air compressor and gas storage pressure vessel shall be carried out to prevent excessive moisture from accumulating and entering the bus processing machine driven by air flow, resulting in corrosion and even damage of parts and components.
Power on, according to the normal power on sequence: main power supply of bus processing machine - power supply of CNC system - power supply of servo system - release the emergency stop button to reduce the impact on electrical components of CNC system and prolong the service life.
After power on, lubrication is an indispensable condition for any moving parts to maintain normal motion track, reduce motion friction and improve service life. This requires us to pay attention to check whether the amount of lubricating oil in the lubricating device is sufficient and replenish it in time when it is insufficient. In addition, we should regularly check whether the liquid filter screen is blocked, whether the oil circuit is unobstructed, and whether there is normal outflow of lubricating oil at each oil outlet point. Once such problems are found, they shall be handled in time. If the moving parts such as the guide rail and lead screw of the bus processing machine work without lubricating oil, on the one hand, it will increase the friction resistance, increase the power consumption of the bus processing machine and waste electric energy. On the other hand, it will accelerate the wear of the moving parts, affect the accuracy of the bus processing machine and the quality of workpiece processing.
The above is what should be checked before the use of the NC bus processing machine. We should pay attention to it in the whole process, so as to give full play to the efficiency of the bus processing machine, improve the processing quality and produce the expected benefits.
