CK61100,CK61125,CK61160 and CKJ61100,CKJ61125,CKJ61160 series are economical large type CNC lathes. Spindle speeds of CK61100,CK61125,CK61160 series are changed by frequency converter in 4 hydraulic gear-shifts,and it’s all manually for CKJ61100,CKJ61125,CKJ61160series. AC servo motor is adopted in feeding system ,and the tailstock is moved electrically .So these machines are ideal equipment for large and middle sized complicated workpieces precision machining in baches.
