随着我国社会主义革命和社会主义建设日益发展,为了保证精密机械高精度加工的要求,全国各地兴建了相当面积的恒温车间。由于恒温车间的造价和日常管理费用昂贵,因此需要从实际出发正确制订精密机械加工的环境温度和湿度规范。 过去我国精密机械加工的恒温车间大多因袭苏修框框, With the socialist revolution in our country and the continuous development of building socialism, in order to ensure the precision machining requirements of high-precision machining, a considerable area of ​​thermostatic workshop has been built across the country. Due to the high cost and daily management cost of a constant temperature shop, it is necessary to correctly formulate the environmental temperature and humidity specifications for precision machining from a practical point of view. In the past, most of our thermostatic workshops for precision machining were struggling with Su boxing,
