As a result of CNC high-speed machine tool a wide range of CNC system, equipment, different structure, a variety of design methods, fault phenomena vary widely, maintenance of CNC equipment is a very difficult job. Therefore, in order to ensure the safe operation of machine tools, CNC high-speed machine linear axis is usually set with a soft limit (parameter setting limit) and hard limit (limit switch limit) two protection "line of defense." But will often occur within the limit failure, then what is the cause of it? The following by the World technical staff for everyone to analyze:
CNC high speed machine
1, the relevant control circuit is broken or the limit switch is damaged
The same time as the above-
The cause of the "limit alarm" is relatively high, due to external components affected by the environment, such as mechanical collision, dust, corrosion, friction and other factors, easy to cause damage to the relevant limit switch itself and control circuit Open circuit, and produce "limit alarm" information. Also encountered after the overtravel switch can not be reset after the situation. This type of fault handling more direct, the damaged switch, wire repair or replacement can be. Wire breakage or poor contact when the need to carefully line and observation,
The same time as the above-
2, the operation is not standardized, malfunction or machine out of control
The same time as the above-
Among them, mainly to cause the hard limit alarm-based, in general, through direct remedial measures can be restored, the use of CNC high-speed machine itself, the overtravel function or short connection is routine maintenance of the usual method.
The same time as the above-
The above is the knowledge of today's share, the emergence of CNC high-speed machine is a good solution to the complex, sophisticated, small batch, multi-species parts processing problems, and it has a very good surface finish, can save polishing time, sometimes Can achieve smooth effect.
