The product design and technology of Dalian automatic processing should be advanced, stable and reliable, and remain basically unchanged for a long time. The adoption of automatic line in mass production can improve labor productivity, stabilize and improve product quality, improve working conditions, reduce production floor area, reduce production cost, shorten production cycle, ensure production balance, and have remarkable economic benefits.

Automatic line of modular machine tool for processing box, shell, miscellaneous parts and so on; Automatic line composed of general, specialized or special automatic machine tools for machining shaft, disc ring and other parts; Automatic processing line of rotating body; Rotor automatic line for machining small parts with simple process, etc. U-shaped production line: arrange the equipment counterclockwise according to the engineering sequence, and one person is responsible for the exit and entrance.

Inquiry and investigation when receiving the information about the troubleshooting of the machine tool on site, first ask the operator to keep the on-site fault state as far as possible without any treatment, which is conducive to the rapid and accurate analysis of the fault cause. Fault analysis analyzes the fault type according to the known fault conditions and the fault classification method described in the previous section, so as to determine the troubleshooting principle. Since most faults are indicated.

Therefore, in general, a variety of possible causes of the fault can be listed according to the NC system diagnosis manual and operation manual of the machine tool. Some faults are often complex and require a series of preparations, such as preparation of tools and instruments, local disassembly, repair of parts and components, procurement of components and even formulation of troubleshooting plan steps, etc.

For the measurement of relevant signal state measurement points set on some circuit boards, use an oscilloscope to observe the amplitude, phase and even presence of relevant pulsation signals, and use a PLC programmer to find out the fault position and cause in the PLC program. The faults in PLC program and processing program are usually equipped with alarm display. According to the displayed alarm number, the possible fault causes and troubleshooting methods can be known by comparing with the corresponding diagnosis instruction manual.
