Jinan Changlong CNC Equipment Co., Ltd.

Jinan Changlong CNC Equipment Co., Ltd. was established early in 2020. After years of development and refinement, it has become an integrated CNC machine production and sales company that combines design, manufacturing, and technical services. In addition to general CNC equipment, the double-head series of processing machines designed and manufactured are widely used for simultaneous processing at both ends of shaft tube shells, saving labor. The double-head lathe can bore large through-holes up to 500, with a double-system double-traverse side spindle movement, allowing simultaneous processing length of up to five meters. The automatic flexible clamping is injury-free and scarless, making it an important choice for the processing of non-metallic pipes such as copper, aluminum, and high polymers. The company's developed hydraulic/electric synchronous self-centering clamps have high precision, large torque, and a wide clamping range, making automatic centering and positioning of shaft tubes more convenient and reliable, and processes like double-head drilling, milling, and boring simpler. The gantry forging press features a vertical clamping, horizontal forging molding, and mold opening design, offering a low-cost, high-efficiency solution for forging and straightening machines for non-standard blanks. The roller spinning technology disperses and releases internal stress, ensuring long-term shape retention. The automatic straightening is stable and efficient, with a diameter 50 round steel requiring only ten seconds!
