A: I've often confused about the kinds of CNC lathe, can you explain them to me? B: OK, let me tell you. CNC lathes are classified as horizontal and vertical CNC lathes. Horizontal CNC lathes are for a longer axial dimension or a small disc-type workpiece turning. Vertical CNC lathes are used to turn large diameter disc-type workpieces. ;A: Do you know about the mechanical components of CNC lathe？ B: I know some of them. They are bed, headstock, three jaw chuck, turret, tailstock, operation panel, protective shield and guide way etc. A: What’s this? B: It’s a three-jaw chuck and a workpiece can be mounted on it.;A: What’s that? B: It’s a bed. These are all the main structure of the lathe. A: Oh, I see. Thanks. B: It is my pleasure. ;1. General introduction about a CNC Lathe 2.Components of a CNC Lathe 3. Hydraulic Control of a Chuck / Tailstock 4. Electrical Control of a CNC Lathe ;CNC lathe is computer numerical control lathe. It is primarily used to rotate body workpieces with turning， boring， drilling， reaming， tapping and other machining processes. 数控车床是计算机数字控制车床，主要用来对旋转体零件进行车削、镗削、钻削、铰削、攻丝等工序的加工。 Firstly， the information for machining workpiece required to process is recorded by the program that is stored in some media when CNC lathes work， and then the program is input to the numerical control device. 数控车床工作时，首先要把加工零件需要的工艺信息以程序的形式记录下来，存储在某些载体上，然后输入到数控装置中。;Processed by the CNC device， command and control signals are issued to servo system that drive machine， coordinate machine movement and make it produce a series of machine movement such as the main motion and feed motion， so complete workpieces machi
