公差这个概念既包括尺寸偏差范围和表 面粗糙度范围， 也包括由热处理和其它处理操 作所引起的机械特性的变化。
Tolerances cover dimensional variation and surface-roughness range and also the variation in mechanical properties from heat treatment and other processing operations.
通过采取一系列相应措施，并对供应商进行指导和提升，确保了配套件的产品质量，逐步修订了关键尺寸的公差范围，提高了减震器的一次装配合格率。
With some proper measures taken including the quality of the supporting parts, the range of tolerance of the key dimensions reduced, thus lifting the one-time fitting acceptance rate of the damper.
公差范围取决于制造机构的精度、机加工过程和尺寸的量值。
The tolerance range will depend on the accuracy of the manufacturing organization, the machining process and the magnitude of the dimension.
