What are the common faults of CNC pipe bending machine?
At present, the CNC tube bending machine produced in China which can be roughly divided into three types: economical pipe bender, popular bending machine and high-grade bending machine. So what are the common faults of CNC pipe bending machines?
1. The main shaft fault of the CNC pipe bending machine .Due to the use of adjustable speed motor, the spindle box structure of CNC tube bending machine is relatively simple, and it is easy to cause failure of the tool holder automatic tensioning device, automatic speed control device, etc.
2. The fault of automatic tool changer (ATC).
3. The fault of feed drive chain.
4. Failure of the accessory.
5. The stroke switch pressing fault for detecting the movement position of each axis.
In the CNC pipe bender, in order to ensure the reliability of the automation work, a large number of stroke switches for detecting the movement position are used. This is also a relatively common symptom. I hope that everyone can analyze and understand the problem after understanding.
