CNC machine tools as the defense industry's strategic equipment, is the most important manufacturing tools of all kinds of weapons and equipment, is an important guarantee for the modernization of national defense and military equipment. A lot of times, the NC machine tool is also called "machining center" ". Since its appearance, the numerical control machining machine tool has brought revolutionary changes to the mechanical manufacturing industry.

数控加工机床在许多方面遵循基本一致的工艺原则。但由于数控加工机床具有自动换刀的特有功能，使得数控加工工艺具有其特点。下边中国机床商务网的小编从加工中心的优缺点两个方面进行分析。

CNC machine tools in many ways to follow the basic principles of the same process. But because of the special function of the automatic tool changing, the NC machining process has its own characteristics. The advantages and disadvantages of the small series of Chinese machine tool business network from the processing center are analyzed in two aspects.

数控加工机床的优点主要体现在以下几个方面：

The advantages of CNC machine tools are mainly reflected in the following aspects:

第一、数控加工机床生产效率高。不仅可省去划线、中间检验等工作，而且由于其具有的自动换刀功能，通常还可以省去复杂的工装，减少对加工零件的安装、调整及多次对刀等相对复杂而繁琐的工作。加工中心能选用最佳工艺线路和切削用量，有效地减少加工中的辅助时间，从而提高生产效率。

First, the production efficiency of CNC machining tools. Can not only save crossed, intermediate inspection work, and because it has the auto tool change function, often omits the complex tooling, reduction of processing parts of the installation, adjustment and multiple knife and other relatively complex and tedious work. The processing center can choose the best processing route and the cutting quantity, which can effectively reduce the auxiliary time in the process, thus the production efficiency can be improved.

.

第二、数控加工机床加工精度高、加工质量稳定。加工中心具有的自动换刀功能，可以非常有效地减少工件的装夹次数，降低或消除因多次装夹带来的定位误差，提髙加工精度。当零件各部位的位置精度要求高时，加工中心具有的自动换刀功能，可以非常方便而有效地减少定位与对刀误差，能在一次装夹与一次性对刀的过程中完成各个部位的加工，保证了各加工部位的位置精度要求。

Second, machining accuracy of CNC machining tools, processing quality and stability. Machining centers with automatic tool change function, can very effectively reduce workpiece clamping times, reduce or eliminate the positioning error due to the multiple clamping, high machining accuracy. When parts of various parts of the position accuracy requirement is high, machining center has automatically change the knife features, can be very convenient and effective to reduce the positioning and tool setting error, in a fixture and disposable knife completed in various parts of the processing, to ensure the position accuracy of the various parts of the processing requirements.

第三、数控加工机床适应性强、灵活性好。加工中心上可方便地实现对箱体类零件进行钻孔、扩孔、铰孔、镗孔、攻摞纹、铣端面和挖槽等多道不同的加工工序，因此能加工轮廓形状特别复杂或难以控制尺寸的零件，如风扇叶片、汽车发动机箱体等零件。能加工复杂曲线类零件以及非常复杂的三维空间曲面类零件。

Third, CNC machining machine adaptability, good flexibility. Machining center can conveniently realize of box type parts of drilling, reaming, reaming, boring, tapping pile pattern, different end milling and dredging multi-channel processes. Therefore, contour shape is particularly complex or difficult to control the size of parts, such as fan blades, a car engine box and other parts. Able to process complex curved parts and complex 3D surface parts.

第四、能提高经济效益，一台数控加工机床，集中了铣床、钻床、攻牙机等多种设备的功能，它可以减少企业机床的数量，因一人可同时操作多台加工中心，减少了操作工人，人工成本相应减少；另外拥有数控加工中心，也是企业实力的具体表现，会促成更多业务量的增加，从而提高经济效益。

Fourth, to improve the economic benefit, a NC machine tools, focused on the functions of milling machine, drilling machine, tapping machine teeth and a variety of equipment, it can reduce the number of machine tool enterprises, because a person can operate a plurality of processing centers, reducing the workers to operate, artificial cost is correspondingly reduced; also has a CNC machining center, the specific performance of the enterprise strength is, contributed to the increase of more traffic, so as to improve the economic benefit.

任何事物都具有两面性，数控加工机床也存在不足之处，主要表现在：加工中心配套的夹具刚度、加工中心自身的刚度和精度保持性要求非常高；加工中心技术复杂，对使用、维修、管理要求较髙；加工中心一次性投资大，需配置其他辅助装置，如数控刀具系统。

Everything has two sides, NC machine tool also has shortcomings, mainly in: supporting the processing center fixture stiffness and machining center of rigidity and accuracy retention requirements are very high; machining center technology complex, the use, maintenance, management requirements is high; machining center one-time investment large, need to configure other assistive devices, such as CNC tool system.

从以上两次方面考察，在购买数控加工机床时，消费者一定要注意选择规模大、实力强、服务有保障的生产单位，这样华球体育中国股份有限公司的质量才能得到保证。

From the above two aspects of the investigation, in the purchase of CNC machine tools, consumers must pay attention to the choice of large, strong, and services to protect the production units, so that the quality of products can be guaranteed.

数控加工机床是一种高度机电一体化的华球体育中国股份有限公司，适用于加工多品种小批量零件，结构较复杂、精度要求较高的零件，需要频繁改型的零件，价格昂贵不允许报废的关键零件，要求精密复制的零件，需要缩短生产周期的急需零件以及要求100%检验的零件。数控加工机床以其卓越的柔性自动化的性能、优异而稳定的精度、灵捷而多样化的功能引起世人瞩目，它开创了机械华球体育中国股份有限公司向机电一体化发展的先河。因此，数控技术成为先进制造技术中的一项核心技术。数控加工机床的特点及其应用范围使其成为国民经济和国防建设发展的重要装备。

NC machine tool is a high degree of mechanical and electrical integration products, applicable to the processing of multi varieties and small batch parts, structure is complex, high precision parts that require frequent modification of parts, expensive and does not allow scrapped the key parts, parts of precision replication, to shorten the production cycle of the needed parts and require 100% inspection of the parts. CNC machine tools to the excellence of the flexible automation performance, excellent and stable precision, agile and diverse functions caused worldwide attention. It opened the machinery products to the development of mechanical and electrical integration precedent. Therefore, numerical control technology has become a core technology in advanced manufacturing technology. The characteristics and application scope of CNC machine tools make it become an important equipment for the development of national economy and national defense construction.

近年来，中国家具及木工机械产业取得了快速的发展，但在中高端华球体育中国股份有限公司领域，国产设备就其品种、质量、可靠性、交货期以及售前售后服务等方面仍相对滞后，尚无法满足巨大的市场需求。目前，我国正处在以高新技术和先进适用技术来改造和提升家具这一传统产业，以信息化建设提升我国家具制造业竞争力的关键历史时期，作为制造、装备信息化的典型关键技术，开展中高端家具及木制品加工设备的应用研究具有重要意义。

In recent years, China's furniture and woodworking machinery industry has made rapid development, but in the field of high-end products, domestic equipment the variety, quality, reliability, delivery period and pre-sales and after-sales service etc. are still relatively backward, is still unable to meet the huge market demand. At present, our country is in the high technology and advanced applicable technologies to transform and upgrade the traditional furniture industry, with construction of informatization promotion our country furniture manufacturing industry competitiveness of the key historical period, as a typical key technology for manufacturing, equipment information, it is very important to study the application of high-end home and wood products processing equipment.

中国作为一个制造大国，主要还是依靠劳动力、价格、资源等方面的比较优势，而在华球体育中国股份有限公司的技术创新与自主开发方面与国外同行的差距还很大。中国的数控加工机床产业不能安于现状，应该抓住机会不断发展，努力发展自己的先进技术，加大技术创新与人才培训力度，提高企业综合服务能力，努力缩短与发达国家之间的差距。力争早日实现数控加工机床华球体育中国股份有限公司从低端到高端、从初级华球体育中国股份有限公司加工到高精尖华球体育中国股份有限公司制造的转变，实现从中国制造到中国创造、从制造大国到制造强国的转变。

China as a manufacturing power, mainly rely on labor, price, resources and other aspects of comparative advantage, and in the product of technological innovation and independent development of the gap with foreign counterparts is also great. China's CNC machine tool industry can not be satisfied with the status quo, should seize the opportunity to continue development, efforts to develop its own advanced technology, increase the intensity of technological innovation and personnel training, improve enterprise integrated service capabilities, to shorten the gap with the developed countries. Strive for the early realization of the transformation of CNC machine tool products from low-end to high-end, from the processing of primary products to sophisticated products manufacturing, from China made in China "to" created in China, from a big manufacturing country to shift manufacturing power.
