Numerical control lathe is by feed of box of lathe bed, main shaft, tool carrier bits of system of system, tailstock, hydraulic pressure, cooling system, lubricant system, platoon implement wait for a part to comprise. 1. The lathe bed structure of lathe of lathe bed numerical control and slideway have a variety of forms, basically have horizontal lathe bed, tilt inclined saddle of lathe bed, level lathe bed. The numerical control lathe of small norms is used in tilt inclined saddle of lathe bed and horizontal lathe bed is more. Tilt lathe bed uses 30º , 45º , 60º , 75º and 90º part more, have 45º commonly usedly, 60º and 75º horn. Lathe of large numerical control and lathe of small-sized and rigid numerical control use horizontal lathe bed more. 2. Advocate transmission system and main shaft component are shown like graph 2-2 place. Of numerical control lathe advocate transmission system uses direct current commonly or communicate electromotor of stepless speed regulation, pass belt-conveyor, drive main shaft to rotate, realize automatic stepless speed regulation and constant to cut speed control. The execution that main shaft component is whirligig of machine tool implementation. Graph feed of 3 X of graph of component of 2 main shaft, Z is smooth board 3. System of transmission of feed of feed transmission system is shown 3 times like the graph. System of transverse feed transmission is to drive tool carrier to make transverse (X axis) mobile unit, it controls the radial dimension of workpiece. Fore-and-aft feed device is to drive tool carrier to make axial (Z axis) athletic device, it controls the axial dimension of workpiece. 4. Tool carrier of automatic circumgyrate tool carrier is the important part of numerical control lathe, it installs all sorts of cutting to machine cutting tool, its structure affects the cutting function of the machine tool and work efficiency directly. The tool carrier cent of numerical control lathe is turn tower type and tool carrier of the type that discharge a knife two kinds big. Turn tower type tool carrier is the tool carrier form that uses generally, it what through turning the whirl of tower head, graduation, fixed position realizes a machine tool is automatic the job that change a knife. If pursue,4 are shown. Two coordinate are successive lathe of pilot numerical control, use 6~12 to be versed in commonly turn tower type tool carrier. Tool carrier of the type that discharge a knife basically is used at lathe of small-sized numerical control, apply to short axis or cover kind of spare parts treatment. If pursue,5 are shown. Graph 4 turn tower type tool carrier pursues tool carrier of 5 knives type CNC Milling CNC Machining
