How to operate the machining center correctly to prolong its service life

With the rapid development of the machining center market, the correct operation method has also been paying attention to people in the coming months. Problems that should be noticed in the use of high-speed machining center Use environment In order to improve the service life of CNC equipment, it is generally required to avoid direct sunlight and other heat radiation, and to avoid too humid, excessive dust or corrosive gases. Keep equipment away from vibration-intensive equipment such as presses and forging equipment.

High-speed machining centers are not suitable for long-term storage. When there are no processing tasks, the machine tools should also be periodically energized. It is advisable to energize them 2 or 3 times a week, each time air-conditioning is about 1 o'clock, to use the heat of the machine tool itself to reduce the humidity inside the machine. , so that electronic components will not be wet, but also in a timely manner to detect whether there is no battery low alarm to prevent the loss of system settings parameters.

Periodically clean or replace the filters or subfilters of each lubrication, hydraulic, and pneumatic system in the high-speed machining center; periodically check the hydraulic system, add and replace hydraulic oil, and regularly discharge water to the gas pressure system of the pneumatic system. . Machine level and mechanical accuracy are regularly checked and corrected. There are two types of mechanical precision correction methods, soft and hard. The soft method is mainly compensated by system parameters, such as screw backlash compensation, machine tool reference position correction, etc. Hard methods are generally performed during machine overhaul, such as rail repair, ball screw nut pre-tightening adjustment Backlash and so on.

Good power supply guarantee In order to avoid large fluctuations in power supply (greater than ± 5%) and possible transient interference signals, high-speed machining centers generally use dedicated line power supply (such as from the low-voltage distribution room to separate one for CNC machine tools) or add stability. Pressure devices, etc., can reduce the impact of power quality and electrical interference. Formulate effective operating procedures In the use and management of CNC machine tools, a series of practical and effective operating procedures should be established. For example, lubrication, maintenance, rational use, and standardized shift system are the main contents of the use and management of CNC equipment. The establishment and observance of operating procedures is one of the important measures to ensure the safe operation of CNC machine tools. Practice has proved that many failures can be reduced or avoided by obeying operating procedures.
