Chaoyang chaogong machine tool co.,ltd.is a individual proprietorship subsidiary of chaogong group,which is a specialixed manufacturer of vertical shaft rotary table grinder.The company is complete in acilities,advanced in technology,perfect in means for test and measurement,strong in technical staff and rich in experience.Our products consist of 74 series vertical shaft rotary table grinders,74series vertical shaft rotary die grinders,MK74 series numerically-controlled vertical shaft table grinders and miniature machining center.The company was authorized gb/tl9001-1994 idt ISO9001:9004standard puality system certificate.
    74 Series Vertical Shaft Rotary Table Grinders have been inproved greatly in rigidity of the bed and grinder head.The three-point adjustment has been adopted and its mechanism is compact.The bench is a round electromagnetic chuck,and the magnetic force of which is smooth and adjustable.the accuracy of the grinder is stable,and the roughness of which is greater than 1.25.The planeness is smaller than0.02/1000.
Disk chuck has been adopted in 74 Series Vertical Shaft Rotary Die Grinders,which can grind to the internal hole,excircle of large workpieces and workpieces with shoulders.Die can work and grind to R-arc without removing Guede-pole,and grinder head can rotate in the range from +45o to -45o.Accordingly,the life of die is longer than before and accuracy of the die is stable.
    MK 74 Series Numercally-controlled Vertical Shaft Rotary Table Grinders are a series of new products improved on the basis of the 74 series surface grinding machines,which adopt with linear guides and ball screws.Grinder head is droved by AC servomotor,and the bench is adjusted with frequency conversion speeder.Therefore,grinding accuracy and work efficiency has been greatly improved.the series machine tools are suitable for autonomous working or automatic mass production line.
    Miniature Machining Center is a new product developed by Tianjin University and us,which can operate tutomatically on drilling,milling,boring,tapping and so on after chucking.The performance index and the accuracy index are in accordance with nationl standard.
    We maintain the principle of “Quality First,Reputation First and Service First”,and we sincerely provide the top quality service for users.We trust our products will be your final selection.
