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 automobile 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.
