The rotating surface of the parts to carry out processing of CNC turning centre, and ordinary lathes, generally can automatically complete the external cylindrical surface, conical surface, spherical surface and thread processing, but also can process some of the complex rotating surface like hyperbolic, etc., lathe and ordinary lathe workpiece installation is basically the same way, in order to improve the machining efficiency, CNC lathes are mostly used in the hydraulic, pneumatic and electric chuck, which can be divided into two major categories of horizontal and vertical, horizontal lathe and horizontal guideway, and the workpiece installation is basically the same, in order to improve the machining efficiency, CNC lathe more hydraulic, pneumatic and electric chuck, which can be divided into two major categories of horizontal and vertical. Horizontal lathe and horizontal guideway and tilt guideway two kinds. Word version download can be edited at will. Higher grade CNC horizontal lathe will usually use the inclined guideway, according to the number of tool holders classification, can be divided into single tool holder CNC lathe and double tool holder CNC car, of which the former is a two-coordinate control, the latter is a 4-coordinate control, double tool holder horizontal lathe most of the use of the inclined guideway, CNC turning centre its appearance with the ordinary lathe is similar to that is, that is, by the bed, the main spindle box, the tool holders, the feed system, the pressure system, cooling and lubrication system, etc. Composition. CNC turning centre feed system and ordinary lathe there is a qualitative difference, the traditional ordinary lathe has a feed box and exchange gear rack, but the CNC lathe is through the ball screw directly let the servo motor drive sliding plate and the tool holder to achieve the feed movement, so the feed system structure is greatly simplified. CNC turning centre types and specifications, can be classified according to the following way. The lathe spindle is perpendicular to the horizontal plane, there is a very large diameter circular table for clamping the workpiece, belongs to the flexible manufacturing system fms. this type of machine tool is mainly used for processing large and complex parts, these parts radial size is large, axial size is relatively small. Their inclined guideway configuration gives the lathe greater rigidity and makes it easy to remove chips, making them suitable for turning disc-type (including short shaft-type) parts. The clamping method is mostly electric or hydraulic control, and the chuck structure has adjustable jaws or unhardened jaws (i.e., soft jaws), which is suitable for turning longer parts and disc parts with not too large diameter. For example, four-station horizontal indexing tool holder or multi-station turret type automatic indexing tool holder, can also be perpendicular to each other. Because of its lower cost, but the degree of automation is not good, the function is also relatively poor, turning accuracy is also not high, so it is suitable for the turning of rotary parts turning processing requirements are not high. The CNC lathe with powerful CNC system, higher degree of automation and higher machining accuracy is more suitable for general turning of rotary parts. This kind of CNC lathe can control two axes at the same time, that is, the X axis and Z axis. 3/4 [Word version download can be edited at will], it increases the C axis and power head, more advanced CNC lathe with tool magazine, it can control the X, Z, and C three axes, linkage control axis can be (X, Z), (X, C) or (Z, C). Due to the addition of the C-axis and milling power head, the processing function of this CNC lathe has been greatly enhanced, it is capable of general turning, but also capable of radial milling, capable of axial milling, capable of milling curved surfaces, capable of drilling holes whose centre line is not in the centre of the part's rotary centre, capable of drilling radial holes and other processing.
