The company takes the European standard sand casting quasi-transmission parts: pulley, cone sleeve, coupling as the leading products, which are sold to the United States, Italy, France and so on. With the unremitting efforts of the leading team of the company, the company has expanded the advanced precision casting, more than 200 sets of processing equipment, and applied the efficient and flexible management system to achieve one-stop production and sales. For many years by the county party committee, county government evaluation foundry casting factory for the "tax payer", "private enterprise", in 2003 was Handan City as "ten export-oriented private enterprises". In 2008, it was rated as "Star Enterprise", "Private Enterprise" and "Outstanding Contribution Award" by the County Party Committee and the County Government. The new reducer exported to Europe and America is the object of our research and development in recent years, which will promote our factory from single production to complete machine production. European and American gear reducer is widely used high added value. But the variety is many, the technical requirement is high. The technical problems encountered are as follows :1) High precision CNC boring machine equipment is needed to solve the concentricity of shaft hole, and the machining of gear shaft can reach 5 levels of accuracy. (2) How to solve the reducer vibration, yaw, oil leakage and other technical problems.
