CNC Graphite Electrode Body Automatic Processing Line

CGK·RZ·02 CNC Graphite Electrode Body Automatic Processing Line

Product Overview

This automatic machining line is mainly composed:

  • CGK-19/CGK-74 type CNC electrode double-end boring and scraping machine tool,
  • CGK-31/CGK-73 type CNC electrode multi-cut outer circle lathe,
  • CGK-32/CGK-75 CNC electrode double-thread comb processing machine tool
  • CG-30/CG-78 type suspended automatic conveyor, etc.,

which automatically complete the boring, scraping, outer circle turning, thread comb processing, end surface precision scraping and automatic conveying during the process of the electrode body. In addition, according to user needs, this automatic processing line can also be equipped with CG-77 electrode nozzle bottom circle and CG-35 detection machine to complete electronic weighing, specific resistance measurement, data printing output, nozzle hole bottom circle, etc.

Technical Note

This automatic processing line is a new generation of fully CNC electrode automatic processing line at home and abroad. Invention Patent No.: ZL 0211 2654.2. The main processes are CNC machine tools, especially the thread comb processing machine tools, which adopt full CNC technology, completely eliminates the error of the mechanical transmission chain, and the overall machining accuracy reaches some international advanced levels. Its control method is unique. Each machine tool adopts a dedicated high-performance CNC system and software developed by our company. It can be debugged and processed separately. The entire line is linked by Siemens PLC, with high automation degree and high production efficiency, and can realize unmanned operations. At the same time, it can be equipped with a host computer, a remote access and remote monitoring system according to user needs.
