What are the instructions for the NC Hobbing Machine?
In view of the above title, and according to the recent development of numerical control technology, especially the open motion controller, this paper aims at the practical requirement of numerical control for small modulus, less number of teeth and large helical angle helical gear hobbing In-depth research has successfully developed a set of NC hobbing systems based on open motion controllers and is used for actual production.
To Germany, Siemens, the Japanese company that CNC system for the mainstream of the NC hobbing machine, greatly improving the gear processing capacity and processing efficiency. China is currently able to produce CNC hobbing machine only 2-3 manufacturers, and the use of many of the German Siemens CNC system, the processing of modulus gear, there is no core technology of independent property rights, the lack of international competitiveness.
The traditional mechanical hobbing machine mechanical structure is very complex, a main motor not only to drive into the indexing transmission chain, but also drive differential and feed drive chain, the transmission chain of each transmission element itself, the processing error will affect the Processing gear processing accuracy, while processing different gears, but also need to replace the various wheel to adjust the complex time-consuming [2], greatly reducing the labor productivity.
