摘　　要：超精密加工所能达到的精度是衡量一个国家制造技术水平的重要标志之一。随着加工精度越来越高,被加工零件对机床周围环境的要求也越来越高。超精密加工中除了液压、气压源的波动外,工作环境的温度、洁净度和振动等方面对加工质量影响很大。因此,主要从气源压力波动、环境温度变化、外界和自身振动几个主要因素,详细介绍了以上因素对超精密零件加工的影响,分析了影响原因,并提出了相应解决途径,为超精密加工环境建设提供了参考。The precision of ultra-precision machining is an important standard to represent a nation- al＇s manufacturing technology. With higher and higher machining accuracy, the parts to be machined on the machine surroundings are of increasingly high requirements.In addition to the fluctuations of hydrardic pressure source ,temperature ,cleanliness of the working environment and vibration in ultra-precision ma- chining also have a great influence on the quality of processing.So here the influence of ultra-precision ac- cessory machining is introduced form the aspects of the gas source pressure fluctuation,environment tem- perature changing, in and outside vibration.The influence causation of machining precision is analyzed,and the solving scheme is put forward.This research provides a reference to construct the ultra-precision ma- chining environment.
