CNC machining to prevent deformation of parts

Computer gong processing is an automatic numerical control machine,

Now many processing enterprises need this kind of mechanical equipment, but due to the fierce market competition, computer gongs processing chaos. The author suggests that before purchasing computer gong equipment, we must have a detailed understanding and investigation of the manufacturer.

Computer gong processing in the process of use will encounter some common faults, such as computer gongs can not return to zero, computer gongs positive and negative hard limit alarm, so what are the causes of these failures?

Cause analysis of computer gong can not return to zero

1. The contact of origin switch is stuck and cannot act;
2. The origin stop can not press the origin switch to the switch action position;
3. The water in the origin switch causes the contact rust and poor contact;
4. The line of origin switch is disconnected or the input signal source is faulty;
5. PLC input point burned out.

Cause analysis of positive and negative hard limit alarm of computer gong

In this case, what is the cause of this normal situation?

1. The contact of travel switch is pressed and stuck (over travel);
2. The travel switch is damaged;
3. There is open circuit, short circuit and no signal source in the travel switch circuit;
4. The limit stop can not press the switch contact to the action position;
5. PLC input point burned out.

Most of the time, due to the improper use of technical personnel, or work handover is not in place, computer gong processing will cause some problems.
