Background technology
CNC milling machine is a kind of automatic processing device grown up on the basis of general milling machine, and both processing technologys are substantially identical, and also some is similar for structure.CNC milling machine has to be divided into is not with tool magazine and the large class of band tool magazine two.CNC milling machine wherein with tool magazine is also called machining center.
NC milling, except having the feature of plain-milling machine processing, also has following features:
1, strong adaptability, the flexibility of part processing are good, can machining profile shape complicated especially or be difficult to the part of controlling dimension, as mould class part, shell part etc.
2, machine tool can be processed cannot process or very unmanageable part, as the complex curve part that describes by Mathematical Modeling and three-dimensional space curved surface class part.
3, after clamped one time location can be processed, the part of multiple working procedure processing need be carried out.
4, machining accuracy is high, crudy is reliable and stable, and the pulse equivalency of numerical control device is generally 0.001mm, and high-precision digital control system can reach 0.1 μm, and in addition, digital control processing also avoid the operate miss of operating personnel.
5, production automation degree is high, can alleviate the labour intensity of operator.Be conducive to automation for production management.
6, production efficiency is high.In addition, CNC milling machine has the function of milling machine, boring machine, drilling machine, makes operation high concentration, substantially increases production efficiency.
Current numerical control machining center is primarily of compositions such as frame, workbench, main shaft, tool magazines.Workbench is arranged in frame, and the surrounding being positioned at workbench in frame is loading device, because loading device is fixing, therefore, is inconvenient to clear up scrap.
