CNC turning and milling composite machine use the reasons for the failure of the initial period of time

CNC turning and milling composite machine tool adopts bed and foot connected body turning sand process, and adopts roller imported line rail and screw, so it has good shock resistance and strong cutting strength. According to different products to achieve spindle positioning, and can cut any polygon processing, in the use of a lot of problems may occur, the use of the initial period of failure may occur frequently, the reasons are generally as follows:

1, the mechanical part.

CNC turning and milling machine tools, although the factory has been running before the break-in, but the time is relatively short, and mainly on the spindle and guideway break-in. Due to the existence of microscopic and macroscopic geometric errors in the machining surfaces of the parts, the machining surfaces of the parts are still relatively rough before the complete break-in, and there may be errors in the assembly of the parts, and thus a large amount of wear and tear will be generated in the early stage of the use of CNC turning and milling composite machine tools, which will produce a large gap between the relative moving parts of the equipment and lead to the occurrence of failures.

2, the electrical part.

CNC turning and milling machine tool control system uses a large number of electronic components, these components, although in the manufacturing plant after a considerable period of aging test and other ways of screening, but the actual use, due to the heat of the circuit, alternating loads, inrush currents and counter-potential impact and other factors, the performance of the poorer some of the components can not withstand the test, due to the current impact or voltage breakdown and scrapped, or characteristic curve Changes occur, which leads to the whole system can not work properly.

3, hydraulic part.

Due to the CNC milling machine factory transportation and installation stage for a long time, so that some parts of the hydraulic system for a long time without oil, lubricant in the cylinder dry, and oil mist lubrication is not possible to play a role immediately, resulting in hydraulic cylinders or cylinders may produce corrosion. In addition, the newly installed air piping if not clean, some debris and moisture may also enter the system, resulting in the initial failure of the hydraulic pneumatic part.
