无论是新安装的或修理后的天平,都存在着程度不同的力角差(简称角差),一般只要角差不超出微分标牌的正负10格或普通标牌的正负5格就可以使用。在使用中的天平由于力壳螺丝紧固程度不同,在天平偏差增大的同时,天平的角差也可能增大;尤其是在换刀以后,角差可能大大超出允许的范围,如果不加以调整,将给天平的变动性和准确性带来很大的影响。所以对天平角差进行调整是天平调修工作中的一个重要项目。
Whether the newly installed or repaired balance, there is a different degree of force angle difference (referred to as the angle difference), generally as long as the angle difference does not exceed the differential sign of plus or minus 10 grid or ordinary signs of plus or minus 5 grid can be used . Balance in use Due to the different degree of tightening of the force-shell screws, the balance’s angular difference may increase at the same time as the deflection of the balance increases. Especially after the tool change, the angular difference may be greatly out of allowable range. If not, Adjustment, will bring great changes in the balance and the accuracy of a great impact. So adjust the balance angle balance adjustment work is an important project.
