On March 15, 2015, the CNC hot forging synchronous robotic arm used on a 250 ton open pneumatic punch press was successfully tested at Ansheng Machinery Co., Ltd. It can produce nuts with a mating edge of 70 for double punch and 80 for single punch, with stable performance and meeting design requirements. The robotic arm of this model can be out of sync with the punching machine, and the height of the produced products can reach about 80. 2015-04-15
