Diagnose in equipment in, vibration is measured diagnosing is one of commonly used effective methods, the some limits in be in a standard with the oscillatory volume level of actual measurement normally will judge the moving condition of equipment. At present more authoritative diagnostic vibration measures a level is by international Organization for Standardization (ISO) makes, to the axis brace up relevant specification is ISO7919-3, housing brace up relevant specification is ISO10816-3, the national level of our country also is to consult this standard and make. In ISO7919-3 standard, to the axis brace up volume level divides for 4 class, after changing according to rotate speed, be as follows: M of μ of border of area of MC/D of μ of border of area of MB/C of μ of border of area of rotate speed R/minA/B leaves factory check and accept be restricted to be worth call the police be restricted to be worth stop machine be restricted to be worth 30008816524115001242323411000152285417 specifications: Area A: The machine that new consign uses falls into this area normally inside. Area B: Vibration considers as what can accept normally in the machine inside this area, can move for a long time without limit. Area C: Here the machine of area is opposite vibration to move for a long time to consider as normally continuously improper. Say commonly, till have equal maintenance opportunity,the machine can run period of time below this condition. Area D: Vibration thinks in this limits the case is severe normally enough causes damage. CNC Milling
