精密加工是現(xiàn)代化科技跟精密機械制造領(lǐng)域中必不可少的一種機械制造工藝,如果要實現(xiàn)精密加工,除了應(yīng)該需要實現(xiàn)這種工藝的數(shù)控設(shè)備、工件材料、刀具以及檢測儀器跟檢測技術(shù)之外,對于環(huán)境的要求也非??量蹋敲磳τ诃h(huán)境的要求都有哪些?
Precision machining is an indispensable mechanical manufacturing process in the field of modern science and technology and precision machinery manufacturing. If you want to realize precision machining, in addition to the numerical control equipment, workpiece materials, cutting tools, testing instruments and testing technology that should realize this process, the requirements for the environment are also very harsh. What are the requirements for the environment?
精密加工的環(huán)境,能夠因為功能不同而有所不同,其設(shè)計眾多方面的技術(shù),所以是各種不同用途相互配個的特有環(huán)境,有鑒于此,需要將對應(yīng)的環(huán)境條件進行綜合配套,比方說,對鋼材而言,溫度變化1攝氏度,每10cm的長度就有可能產(chǎn)生1um的變形。
The environment of precision machining can be different due to different functions, and its design has many aspects of technology, so it is a unique environment for different purposes. In view of this, it is necessary to comprehensively match the corresponding environmental conditions. For example, for steel, if the temperature changes by 1 degree Celsius, it is possible to produce 1um deformation for every 10cm length.
換句話說,對于要求是0.1um的精密加工,必須有能夠控制小于0.1攝氏度的溫度變化的措施,并且,對于使用光的裝置來說,因為微小的外部換金變化都會引起光軸的偏移。
In other words, for precision machining that requires 0.1um, there must be measures that can control the temperature change less than 0.1 degrees Celsius, and for devices that use light, small external gold exchange changes will cause the optical axis to shift.
所以,對于微小振動、日照、溫度變化所引起的房屋的熱脹冷縮以及室內(nèi)空氣波動跟電磁波影響也有著相應(yīng)的要求,從這兒可以看出來,精密加工的潔凈環(huán)境不僅僅是確??諝獾臐崈舳榷?;
Therefore, there are also corresponding requirements for the thermal expansion and contraction of houses caused by small vibration, sunshine and temperature changes, as well as the impact of indoor air fluctuations and electromagnetic waves. It can be seen from here that the clean environment of precision machining is not only to ensure the cleanliness of the air;
在設(shè)置精密加工潔凈環(huán)境的時候,不能夠進行單獨的設(shè)置,需要采取空間序列化方式,組成由低層次向高層次的流向線,只有這樣,即便是在環(huán)境遭遇破壞的時候,超精讀環(huán)境系統(tǒng)也能夠得到應(yīng)有的保護,精密環(huán)境的整體設(shè)施的一部分是將精密環(huán)境包圍其中的結(jié)構(gòu);
When setting up a clean environment for precision machining, it is not possible to set it separately. Instead, it is necessary to adopt a spatial serialization method to form a flow line from low level to high level. Only in this way, even when the environment is damaged, the ultra precision reading environment system can be protected. Part of the overall facilities of the precision environment is the structure that surrounds the precision environment;
濟南注塑加工廠家提醒您,在精密加工過程中,一個顆粒直徑為0.3um的灰塵,就會引起判斷錯誤而發(fā)生報廢,在沒有凈化的車間內(nèi)裝配空氣軸承或者是其他的精密軸承,落入的灰塵會拉毛零件的表面。
Jinan injection molding manufacturer reminds you that in the process of precision machining, a dust with a particle diameter of 0.3um will cause misjudgment and scrap. If air bearings or other precision bearings are assembled in the workshop without purification, the dust will roughen the surface of parts.
所以,為了進行精密加工,需要建立潔凈室,潔凈室所指的是將空氣中的灰塵、細微顆粒以及室內(nèi)的氣壓、溫度、濕度、氣流分布跟形狀、速度等控制在一定的范圍之內(nèi)而采取措施的房間。
Therefore, in order to carry out precision processing, it is necessary to establish a clean room. A clean room refers to a room that takes measures to control the dust and fine particles in the air as well as the indoor air pressure, temperature, humidity, air distribution, shape, speed, etc. within a certain range.
此外還要防止靜電環(huán)境,因為靜電會造成半導(dǎo)體元器件的傷害,讓膠片感光,出現(xiàn)氣泡以及粘附灰塵等顆粒,造成生產(chǎn)跟質(zhì)量事故,所以,需要采取防止物體帶電的措施。更多相關(guān)內(nèi)容就來關(guān)注我們網(wǎng)站

In addition, it is also necessary to prevent the electrostatic environment, because static electricity will cause damage to semiconductor components, make the film sensitive, produce bubbles, adhere to dust and other particles, and cause production and quality accidents. Therefore, it is necessary to take measures to prevent objects from being charged. Follow our website for more relevant content http://www.wuguliang.net Come on!
