數控加工中心是由機械設備與數控系統(tǒng)組成的適用于加工復雜零件的高效率自動化機床。數控加工中心是目前世界上產量最高、應用比較廣泛的數控機床之一。它的綜合加工能力較強，工件一次裝夾后能完成較多的加工內容，加工精度較高，特別是它能完成許多普通設備不能完成的加工，對形狀較復雜，精度要求高的單件加工或中小批量多品種生產更為適用。下面就簡單介紹下數控加工中心的有哪些優(yōu)勢：
（1）數控加工中心的功能
數控加工中心是一種功能較全的數控加工機床。它把銑削、鏜削、鉆削、攻螺紋和切削螺紋等功能集中在一臺設備上，使其具有多種工藝手段。加工中心設置有刀庫，刀庫中存放著不同數量的各種刀具或檢具，在加工過程中由程序自動選用和更換。
（2）數控加工中心的自動化程度高
工件在加工中心上經一次裝夾后，數字控制系統(tǒng)能控制機床按不同工序，自動選擇和更換刀具，自動改變機床主軸轉速、進給量和刀具相對工件的運動軌跡及其他輔助機能，依次完成工件幾個面上多工序的加工，并且有多種換刀或選刀功能。
（3）數控加工中心的開機利用率高
加工中心由于工序的集中和自動換刀，減少了工件的裝夾、測量和機床調整等時間，使機床的切削時間達到機床開動時間的80%左右(普通機床僅為15～20%)；同時也減少了工序之間的工件周轉、搬運和存放時間，縮短了生產周期，具有明顯的經濟效果。加工中心適用于零件形狀比較復雜、精度要求較高、產品更換頻繁的中小批量生產。
（4）數控加工中心的精度更高
數控加工中心的加工質量穩(wěn)定，多品種、小批量生產情況下生產效率較高，能減少生產準備、機床調整和工序檢驗的時間，而且由于使用比較佳切削量而減少了切削時間，并且可加工常規(guī)方法難于加工的復雜型面，甚至能加工一些無法觀測的加工部位。
CNC machining center is an efficient automatic machine tool which is composed of mechanical equipment and CNC system. The CNC machining center is one of the most widely used CNC machine tools in the world. Its comprehensive processing ability is relatively strong. After the workpiece is clamped, more processing content can be completed. The machining accuracy is high. In particular, it can complete many processes that can not be completed by ordinary equipment, and the shape is more complex. The single piece processing or medium and small batch multi-variety production with high precision requirements is more suitable. The following is a brief introduction to the advantages of the CNC machining center:
(1) The function of CNC machining center is comprehensive
The CNC machining center is a kind of CNC machining machine with full function. It concentrates the functions of milling, boring, drilling, tapping and cutting threads on a single device, so that it has a variety of technological means. The processing center is equipped with a knife library, which contains a variety of different types of knives or inspection tools. In the process of processing, the program is automatically selected and replaced.
(2) High degree of automation of NC machining centers
After the workpiece is clamped at the processing center, the digital control system can control the machine tool to automatically select and replace the tool according to different procedures, automatically changing the spindle speed, feed amount, and the tool's movement trajectory relative to the workpiece and other auxiliary functions. Complete the processing of several parts of the workpiece in turn, and there are many kinds of knife replacement or knife selection functions.
(3) High utilization rate of boot up of NC machining center
The processing center reduces the time for loading, measuring, and adjustment of the workpiece due to the concentration of the process and the automatic replacement of the knife, so that the cutting time of the machine tool reaches about 80 % of the operating time of the machine tool(the average machine tool is only 15 to 20 %); At the same time, it also reduces the workpiece turnover, handling and storage time between processes, shortens the production cycle, and has obvious economic effects. The processing center is suitable for medium and small batch production with complex parts shape, high accuracy requirements, and frequent product replacement.
(4) The precision of NC machining center is higher
The machining quality of the CNC machining center is stable, and the production efficiency is higher under the conditions of multi-variety and small batch production. It can reduce the time for production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the optimal cutting amount. And it can be processed complex surfaces that are difficult to process by conventional methods, and can even process some unobservable processing parts.
