Making use of air pressure and air flow to carry on all sorts of work is called "pneumatic technology", and the air in compressed state is called "compressed air". Air is the raw material of the compressed air, therefore, the chemical properties of the compressed air is same as air. As power source, it has the feature of high safety, pollution-free, etc. In addition, the storage capacity of compressed air is very strong. As long as the storage vessel seals well, the energy can be kept in the container all the time. The compressed air has many advantages as a kind of power, so it is widely used. Function of compressed air Because the air is one of the most common compressed medium, the compressed air is easy to get and it can’t cause pollution, so the compressed air is used in various areas and industries to realize automation and to save labor costs. So because of the feature of the high-pressure compressed air, it is possible to be applied in industry of coordinate measuring machine. For CMM, compressed air has the following application: The compressed air can provide power for static pressure type air bearing (also called air bearing. Below we will call it air bearing). Most CMM adopt zero friction movement of air bearing. The principle is to input high-pressure compressed air from the inlet into air bearing, then the air flow out through the hole on the surface of the air bearing. Thus, there will be an air space like a certain thickness of air film between air bearing and guide way. The air film can make the movement of the moving parts to realize approximate zero friction. In this way, it can guarantee the normal work of CMM. Therefore, the compressed air can guarantee the normal work of CMM. The compressed can provide power for cylinder balance. As for the coordinate measuring machine, Z axis is in the vertical direction, so the force made by the weight must be eliminated by other components. Due to the advantages of the smooth movement, reliable positioning, simple structure and easy adjustment, the balance cylinder is currently the first choice for the balance part of all the coordinate measuring machines. The function of the high pressure compressed air is obvious in the balance system.

Učinak pritiska zraka kutem od CMM. 1. pritisak Pod normalni radni tlak, debljina zračnog prostora između klima ležaj i vodič željeznicom je fiksna, koji može osigurati dobra ponovljivostCMM. Ako tlak zraka varira, promjena unaprijed stezanja sile putanju zraka će prema tome dovesti do promjena inter membranskih prostora. Kad inter membranu prostor postaje vrlo mali, postoji određeni trenje između zraka ležaj i vodilicu, što može prouzrokovati relativna trenje između zraka ležaj i vodilicu dok stroj radi. Čak i ozbiljno možete uzrokovati ogrebotine na vodilicu i utjecajni stroj performanse. 2. efekt ravnotežu cilindar Ravnoteža cilindar služi za ravnotežu Z osi. Kada Z osi gravitacije jednaka privlačnih sila generira cilindru tlak zraka, os Z će držati ravnotežu. Nakon što je cilindar privlačnih sila manja od gravitacije, cijela ravnoteža sustava će biti van kontrole. Z osi kao Sonda glavu će pasti. To može oštetiti sondu i Z osi. Stoga, je vrlo potrebno da se osigura pritisak komprimiranog zraka za CMM. IakoNaša tvrtkapoduzela niz mjera za kontrolu negativnih posljedica Fluktuacija tlaka komprimiranog zraka, kako biste osigurali da možete koristiti u CMM normalno, molimo strogo kontrolirati tlak od CMM.
