Since the 1970s, the North Gear Machinery Power Plant has copied the West German double-head straight bevel milling machine, which is the first manufacturing plant in China. With the world's machine tool industry fully entering CNC automation, the mechanical power plant began to cooperate with Henan University of Science and Technology in 2005 to carry out numerical control transformation of the Y2726 straight bevel gear milling machine.
First, use an existing equipment of the import and export company to carry out overhaul and restore the factory precision. The original mechanical hydraulic transmission system was replaced by Siemens digital control system, and the cradle and indexing head transmission system were redesigned and manufactured, and the original gearbox, machine wheel hanging mechanism and counter were eliminated. In order to match with the numerical control system, the original hydraulic system was modified, the original manual control was changed to automatic control, the special hydraulic components were reduced, and the movement of the cradle and the indexing head was controlled by the servo motor through the numerical control system. CNC machining of milling teeth.
The modified CNC machine tool greatly reduces the complicated program of calculating the adjustment card and machine adjustment. The operator will automatically display it on the screen as long as the relevant parameters are input. Moreover, the factory precision and smoothness of the original machine tool are improved by an accuracy level, which greatly reduces the noise of the machine tool, greatly improves the quality of the processed product, improves the production efficiency, and is recognized by the user.
