隨著cnc加工技術的不斷成熟，許多高科技產品的外殼都采用CNC加工制造。CNC加工能夠實現對產品外殼的高精度、高速度加工，保證產品的精密度和外觀質量(liang)。那么，如何利用CNC加工技術高質量(liang)制造(zao)外殼呢？

　　1.在(zai)設計外(wai)殼時，要考慮產(chan)品的整體(ti)外(wai)形尺寸和(he)形狀，以及零部件的尺寸和(he)位置。設計師需要根據產(chan)品的功(gong)能和(he)使用(yong)環(huan)境，選(xuan)擇合(he)適的材料和(he)工(gong)藝，并(bing)考慮到CNC加工(gong)的特點和(he)限制，設計出合(he)理的外(wai)殼。

　　2.選擇(ze)材料(liao)(liao)時，要(yao)根(gen)據產(chan)品(pin)的(de)(de)使用環境(jing)和功能(neng)(neng)，選擇(ze)合適的(de)(de)材料(liao)(liao)。一(yi)般來(lai)說，機械產(chan)品(pin)外殼(ke)的(de)(de)材料(liao)(liao)要(yao)求耐(nai)(nai)磨、耐(nai)(nai)沖擊(ji)、耐(nai)(nai)腐(fu)蝕、耐(nai)(nai)高溫(wen)，而光學產(chan)品(pin)外殼(ke)的(de)(de)材料(liao)(liao)要(yao)求耐(nai)(nai)高溫(wen)，并具有較好的(de)(de)硬度、剛度和抗沖擊(ji)性(xing)(xing)。此外，還需要(yao)考慮(lv)材料(liao)(liao)的(de)(de)機械性(xing)(xing)能(neng)(neng)、導(dao)電性(xing)(xing)、熱(re)傳導(dao)性(xing)(xing)、耐(nai)(nai)磨性(xing)(xing)、抗沖擊(ji)性(xing)(xing)、阻燃性(xing)(xing)、耐(nai)(nai)腐(fu)蝕性(xing)(xing)和耐(nai)(nai)熱(re)性(xing)(xing)。

　　3.在設計外(wai)(wai)殼(ke)(ke)時，應考慮外(wai)(wai)殼(ke)(ke)的(de)結構、工(gong)藝和(he)性(xing)能(neng)等(deng)因素，該設計將直接影(ying)響外(wai)(wai)殼(ke)(ke)的(de)成(cheng)(cheng)本、交(jiao)付時間和(he)質量(liang)。外(wai)(wai)殼(ke)(ke)的(de)結構一(yi)般分為單殼(ke)(ke)和(he)雙(shuang)殼(ke)(ke)兩種。單殼(ke)(ke)一(yi)般由一(yi)塊板(ban)材剪切而成(cheng)(cheng)，而雙(shuang)殼(ke)(ke)則是由兩塊不同板(ban)材密封而成(cheng)(cheng)。外(wai)(wai)殼(ke)(ke)的(de)工(gong)藝一(yi)般有注塑、鑄造(zao)、沖壓和(he)熱(re)成(cheng)(cheng)型等(deng)。外(wai)(wai)殼(ke)(ke)的(de)性(xing)能(neng)一(yi)般包括防(fang)水性(xing)、防(fang)塵性(xing)、防(fang)護性(xing)、耐磨性(xing)和(he)耐沖擊性(xing)等(deng)。

　　4.在CNC加(jia)工外殼時，應充分(fen)考慮機械性能、導(dao)(dao)電性、熱傳(chuan)導(dao)(dao)性、耐磨性、抗沖擊性、阻(zu)燃性、耐腐蝕性和耐熱性。

　　機械性(xing)能是CNC加(jia)(jia)工外殼的基本性(xing)能，導(dao)(dao)電(dian)性(xing)和(he)熱(re)傳導(dao)(dao)性(xing)是CNC加(jia)(jia)工外殼的主要性(xing)能。耐磨(mo)性(xing)和(he)抗沖(chong)擊性(xing)是CNC加(jia)(jia)工外殼的次(ci)要性(xing)能。阻燃性(xing)和(he)耐腐蝕性(xing)是CNC加(jia)(jia)工外殼的特殊性(xing)能。耐熱(re)性(xing)是CNC加(jia)(jia)工外殼的附(fu)加(jia)(jia)性(xing)能。

　　With the continuous maturity of CNC machining technology, the shell of many high-tech products is manufactured by CNC machining. CNC machining can realize high-precision and high-speed machining of product shells, so as to ensure the precision and appearance quality of products. So how to use CNC machining technology to manufacture high-quality shells?

　　1. In the design of the shell, the overall size and shape of the product, as well as the size and position of the parts, should be considered. Designers need to choose appropriate materials and processes according to the function and use environment of the product, and take into account the characteristics and limitations of CNC machining, so as to design a reasonable shell.

　　2. When choosing materials, appropriate materials should be selected according to the use environment and functions of the products. Generally speaking, the materials of mechanical product shells should be wear-resistant, impact-resistant, corrosion-resistant and high-temperature resistant, while the materials of optical product shells should be high-temperature resistant, and have good hardness, stiffness and impact resistance. In addition, the mechanical properties, conductivity, heat conductivity, wear resistance, impact resistance, flame retardancy, corrosion resistance and heat resistance of the materials need to be considered.

　　3. In the design of the shell, factors such as structure, process and performance of the shell should be considered. This design will directly affect the cost, delivery time and quality of the shell. The structure of the shell is generally divided into two types: single shell and double shell. The single shell is usually cut from a single piece of plate, while the double shell is sealed by two different plates. The process of the shell is generally injection molding, casting, stamping and thermoforming. The performance of the shell generally includes water resistance, dust resistance, protection, wear resistance and impact resistance.

　　4. In the process of CNC machining the shell, the mechanical properties, conductivity, heat conductivity, wear resistance, impact resistance, flame retardancy, corrosion resistance and heat resistance should be fully considered.

　　Mechanical properties are the basic properties of CNC machined shells, and conductivity and heat conductivity are the main properties of CNC machined shells. Wear resistance and impact resistance are the secondary properties of CNC machined shells. Flame retardancy and corrosion resistance are the special properties of CNC machined shells. Heat resistance is an additional property of CNC machined shells.
