Qingdao Yongji Heavy Machine Tool Co.,Ltd (Former Qingdao Fourth Machine Tool Factory),established in 1958, lies in Qingdao Environmental Protection Industrial Park,covering 100,000 square meters. we are specially engaged in heavy CNC gantry machining center machine and single column vertical lathe ,double column vertical lathe,CNC vertical lathe,CNC heavy vertical lathe.We have a very powerful expert team for designing,machining,installation and quality inspection,having the ability of research and development,manufacturing and assembly.We can produce over 400 sets per year and successfully sale our product to more 20 countries including France,German,America,Korea,Brazil and so on.

1. The design of column effectively to enlarge the ground area can make machine cutting more stable.

2. Hydraulic pieces all adopt import accessories,good stability,low trouble rate ,low noise, utmost to protect the servo motor

3. Machine bed,column,beams,slide,ram are adopt resin sand shape of high strength casting iron and reasonable of reinforced structure, good rigidity, strong stability.

4. The main movement adopts width speed AC servo main motor and equipts ZF gearbox, making spindle output large torque at low speed,suiting for heavy cutting,constant power suits for finishing machining at high speed.

5. Spindle is prop up by exclusive bearing of precisional machine spindle ,after pre - tighten making spindle rigidity and rotary accuracy good.The adoption oil colder(circulatory system) to cool spindle set and availably control the spindle set heating.
