CK6420 series CNC lathe is a kind of small-sized precision CNC lathe with high accuracy and high performance. It is mostly suitable for machining big-batch of high-precision, high-efficiency, complicated, small-sized revolving Workpieces in instrument, electronic, light industry, medical appa-ratus and instruments, aviation and so on industries.The bearings of main parts all adopt Sweden SKF and Japan NSK products, whose driving noise is low, thus ensures high-accurcy maching and long service lift.This machine can be equipped with Japan FANUC sys-tem, Dasen system and Guangzhou G980T system, or other CNC systems in accordance with requests. This machine adopts row-type tool post, whose changing tool' time is short, thus the production efficiency is high. This machine is equipped with spring collets and chucks controlled by pneumatic system or by hydraulic system.
