CK、CKA、CKJ为经济实用型数控车床系列。结构成熟、性能稳定、*、编程容易、操作简单、适用于各种形状复杂的轴、套、盘类零件的内外表面、圆锥面、圆弧面、各种螺纹甚至孔的钻、扩、铰序等车削加工，尤其适合于多品种、中小批零件的轮番加工。该系列机床*性好、效率高、废品率低、*性好，因而广泛应用于各种行业诸如汽车、石油、等的机械加工。
CK系列通过变频器及液压四档自动转换，主轴可实现全程分段无级调速；CKJ系列通过手动换挡，实现18级转速；CKA系列则采用液压六档自动转换及三档手动转换实现12级转速的半自动变速形式。
CK、CKJ、CKA series are economical and practical CNC lathes. With optimized structures ,unfailing performance,high quality ,simple programming ,and easy handling,they are suitable for turning of complicated shaft,sleeve,and disk type work-pieces such as turning of internal and external cylindrical ,conical ,arc surfaces and various threads,and even drilling ,boring and reaming holes. And they are especially fit for turning of diversified work-pieces on small and medium batches. They are of high versatility ,high efficiency,low inferiority and good conformability.So to be widely used in various trades,such as auto industry,petroleum industry ,military industry ,and so on.
CK series CNC lathes may accomplish step-less spindle speed-changing by means of main motor frequency conversion and 4-shift hydraulic gear-change;CKJ series CNC lathes obtain 18 speeds all manually;and CKA series spindle speed changing introduces 6-shift hydraulic gear-change and 3-shift manual gear-change to obtain 12 speeds.
