Abstract: Most domestic broaching machine with hydraulic drive, aiming at the drawbacks that domestic broaching machine are processing quality(accuracy and finish) poor, energy waste and environmental pollution, a system of broaching machine based on permanent magnet AC servo system synchronous driving with the sophisticated intelligent and superior performance permanent magnet AC servo system was designed. The advantage of servo synchronous driving broaching applying in industrial production was described firstly, the vertical internal broaching of servo synchronous driving charts was also given, and an analysis of the characters of organization chart was provided. The design of main slider servo synchronous driving systems, tool servo drive systems and control system software of broaching are expounded emphatically, and the synchronization control strategy of sharing instruction was used to ensure the synchronization performance of broaching machine. Finally, the vertical internal broaching machine was tested under a load of 20 tons force. The test results indicate that the designed control system has the advantages of low cost, good feasibility, stable synchronization performance, high manufacturing accuracy,which has a certain guiding significance for development of domestic broaching machine.
