數(shù)控加工中心是由機(jī)械設(shè)備與數(shù)控系統(tǒng)組成的適用于加工復(fù)雜零件的高效率自動(dòng)化機(jī)床。數(shù)控加工中心是目前世界上產(chǎn)量最高、應(yīng)用比較廣泛的數(shù)控機(jī)床之一。它的綜合加工能力較強(qiáng)，工件一次裝夾后能完成較多的加工內(nèi)容，加工精度較高，特別是它能完成許多普通設(shè)備不能完成的加工，對(duì)形狀較復(fù)雜，精度要求高的單件加工或中小批量多品種生產(chǎn)更為適用。下面就簡(jiǎn)單介紹下數(shù)控加工中心的有哪些優(yōu)勢(shì)：
（1）數(shù)控加工中心的功能
數(shù)控加工中心是一種功能較全的數(shù)控加工機(jī)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(tái)設(shè)備上，使其具有多種工藝手段。加工中心設(shè)置有刀庫(kù)，刀庫(kù)中存放著不同數(shù)量的各種刀具或檢具，在加工過程中由程序自動(dòng)選用和更換。
（2）數(shù)控加工中心的自動(dòng)化程度高
工件在加工中心上經(jīng)一次裝夾后，數(shù)字控制系統(tǒng)能控制機(jī)床按不同工序，自動(dòng)選擇和更換刀具，自動(dòng)改變機(jī)床主軸轉(zhuǎn)速、進(jìn)給量和刀具相對(duì)工件的運(yùn)動(dòng)軌跡及其他輔助機(jī)能，依次完成工件幾個(gè)面上多工序的加工，并且有多種換刀或選刀功能。
（3）數(shù)控加工中心的開機(jī)利用率高
加工中心由于工序的集中和自動(dòng)換刀，減少了工件的裝夾、測(cè)量和機(jī)床調(diào)整等時(shí)間，使機(jī)床的切削時(shí)間達(dá)到機(jī)床開動(dòng)時(shí)間的80%左右(普通機(jī)床僅為15～20%)；同時(shí)也減少了工序之間的工件周轉(zhuǎn)、搬運(yùn)和存放時(shí)間，縮短了生產(chǎn)周期，具有明顯的經(jīng)濟(jì)效果。加工中心適用于零件形狀比較復(fù)雜、精度要求較高、產(chǎn)品更換頻繁的中小批量生產(chǎn)。
（4）數(shù)控加工中心的精度更高
數(shù)控加工中心的加工質(zhì)量穩(wěn)定，多品種、小批量生產(chǎn)情況下生產(chǎn)效率較高，能減少生產(chǎn)準(zhǔn)備、機(jī)床調(diào)整和工序檢驗(yàn)的時(shí)間，而且由于使用比較佳切削量而減少了切削時(shí)間，并且可加工常規(guī)方法難于加工的復(fù)雜型面，甚至能加工一些無(wú)法觀測(cè)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.
