What are the common faults in the hydraulic system of CNC machine tools?
CNC machine tool processing has brought great convenience to our industrial life.Hydraulic system,as one of the important structures of CNC machine tools,plays a vital role in the work of CNC lathes.The problems of hydraulic system seriously affect CNC lathes.Working condition.The following small series will take you to see more common faults in the hydraulic system.
1.Hydraulic system oil pollution
Oil pollution is a common phenomenon in hydraulic systems.Oil pollution is also an important cause of the whole hydraulic system.Because the hydraulic system components will have some pollutants entering the system during the assembly process,and even in the system operation,because of some The sealability of the parts will also form aggression of contaminants.When the pollutants in the hydraulic system exceed a certain amount,the hydraulic system will be shut down or the system will be destroyed.Others,because some protection and maintenance personnel have a small sense of job responsibilities and enthusiasm for work,daily protection operations are not in place,resulting in oil contaminants in the hydraulic system not being removed in time,which is also an important reason for the formation of pollutants.
2,hydraulic system sensation and noise
Hydraulic system sensation and noise are one of the common problems in hydraulic systems.The first thing is that the operating frequency of the hydraulic pump resonates with the system that is unique to the CNC machine.Other hydraulic pumps will draw in some air during normal operation.These bubbles will The effect of high pressure is instantaneously released,and a pressure pulsation occurs,which is a noise generated by the hydraulic system during operation.The sensation of the hydraulic system and the noise have a very strong impact on the operation of the entire CNC machine tool,affecting the power and quality of CNC machine tools.
3,the hydraulic system
The data in the hydraulic system of the machine tool has a very arrogant effect on the operation of the whole system,which will directly affect the quality of the machined parts of the CNC machine.The primary causes of hydraulic system defects are as follows:First,the conflicting force changes during low-speed motion.The paralyzed phenomenon of CNC machine tools is mainly presented in the low-speed motion of the system.This is mainly because the conflict is added because of too many contact surfaces.,a paralysis phenomenon.Second,the wear of the components will cause defects.In the operation of the CNC machine tool,the loss of components will be presented.This will add gaps between the components,affecting the sealing of the components,and affecting the thrust of the hydraulic cylinder to a certain extent.Force causes paralysis.
The above is the fault that often occurs in the hydraulic system.The fault occurs on the one hand because of the problem of its own product work,and on the other hand,our maintenance is not in place.In the future,the demand will further focus on and improve the protection of the hydraulic system of CNC machine tools,reduce the typical problems of the hydraulic system,and ensure the smooth operation of CNC machine tools.
