添加剂：一种化学品，少量增加到切削液中以影响切削液的某些特性。
AGING: The process of running product through low temperature air draw furnaces for the purpose of relieving stress which was caused in the hardening operation. The process stabilizes the microstructure of the product so it will retain desired dimensions during use. Also called tempering or drawing.
时效处理：指让产品通过低温通风炉以释放淬火造成的应力的工艺。这道工艺可以稳定产品的内部微观结构，在实际工作中能保持产品的尺寸稳定性。也称为回火。AIR COOL: To cool by passing air over, into, around or through; cooling hot product to room temperature using air as a quenching medium.空气冷却：用空气作为冷却介质，通过空气使高温的产品冷却到室温。ALL PURPOSE BEARING: 60后省委书记
