Pressure Under normal working pressure, the thickness of air space between air bearing and guide rail is fixed, which can ensure good repeatability of CMM. If the pressure of air supply fluctuates, the change of the pre-tightening force of the air bearing will accordingly lead to the change of inter membrane space. When the inter membrane space becomes very small, there is a certain friction between air bearing and guide rail, which may cause relative friction between air bearing and guide rail when the machine is running. It may even seriously cause scratches on guide rail and influent machine’s performance. The effect to balance cylinder Balance cylinder is used to balance Z axis. When the Z axis gravity equals to the attractive force generated by cylinder air pressure, Z axis will keep balance. Once the cylinder attractive force is less than gravity, the whole balance system will be out of control. Z axis as well as the probe head will drop down. It may damage the probe and Z axis. Therefore, it is very necessary to guarantee the right pressure of compressed air for CMM. Although our company has taken a variety of measures to control the negative result of fluctuation of the compressed air pressure, in order to guarantee that you can use the CMM normally, please strictly control air pressure of CMM.

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.
