Huludao Shougang Donghua Machinery Co., Ltd is a state-owned enterprise that designs, researches, develops and manufactures special equipment for elevator guide rail. It was originally a non-standard equipment enterprise used to be attached to the National Ministry of Weapon Industry. Depending on its strong ability of designing and manufacturing, in recent years, it has supplied guide rail planning machines to the following users: Shougang Savera in Beiging, Changjiang Runfa in Zhangjiagang and Sanhang in Hangzhou. It can also make other machines of the guide rail production lineincluding planning machine, straightening machine, automatic transforming machine and end finish machining etc. The technology of the production line is advanced in the world. Main processing flu and machines are:

1. removing rust of blank ( the machine uses automatic sand blasting to remove rust.) ――2. straightening ( the machine can straight the guide rail automatically according to the curve and twist of the guide rail.) ――3. planning (high-speed guide rail planning machining consists of loading system through robot, assembling and fixing system, cutters rotating system, machine body system, main drive system, unloading system through robot, automatic bilateral chip removing system, cooling system, hydraulic system, pneumatic system, computer controlling, adjusting, setup system and electric control tank group. In addition, we can adjust the machine according to the needs of users, such as adjustment of the direction of loading and unloading system. planning (high-speed guide rail planning machining consists of loading system through robot, assembling and fixing system, cutters rotating system, machine body system, main drive system, unloading system through robot, automatic bilateral chip removing system, cooling system, hydraulic system, pneumatic system, computer controlling, adjusting, setup system and electric control tank group. It is mainly used to machine two sides and top surface of K value.) ――4. back milling ( Back milling machine is mainly used to mill the plane surface of the two ends of guide rail bottom.) ――5. yang tenon (Machine special for guide rail end machining can automatically mill the right end surface of guide rail and performs the size-- m₂ once. )――6. ying tenon ((Machine special for guide rail end machining can automatically mill the left end surface of guide rail and performs the size—m₁ once，ensures the total length of the guide rail.) ――7. drilling holes (Special drilling machine is mainly used to drill the holes d of two sides of guide rail.) ――8. widening holes (Special drilling machine is mainly used to drill the holes d₁ of two sides of guide rail.) ――9. precision straightening ( Precision straightening machine is used to strengthen stress deformation of guide rail machined )――10. cleaning ――11. painting――12. drying――13. oiling――14. transfer coating ――15. off line.  

Note: All midway transformations during machining guide rail are automatic. We can design, manufacture production line special for guide rail. Do you want to own advanced guide rail production line around the world? Do you want to manufacture the guide rail with maximum accuracy in the world? Do you want to finish machining guide rail with fewer operators? Then please contact us. The earlier you process the line, the more you have the market share. Hand in hand with us, success is in sight!
