CNC machining manufacturer
The accuracy of precision CNC machining is affected by natural climate. China has a vast territory, with most areas located in subtropical regions. The temperature changes greatly throughout the year, and the temperature difference varies throughout the day. Therefore, people have different intervention methods and levels for indoor (such as workshop) temperature, and the temperature atmosphere around the machine tool is also different. For example, in the Yangtze River Delta region, the seasonal temperature change range is about 45 ℃, and the diurnal temperature change range is about 5-12 ℃. The CNC walking machine machining workshop generally does not have heating in winter and air conditioning in summer, but as long as the workshop has good ventilation, the temperature gradient in the CNC walking machine machining workshop does not change much. In the northeast region, the seasonal temperature difference can reach 60 ℃, and the diurnal variation is about 8-15 ℃. From late October to early April of the following year, the processing workshop is designed with heating, but the indoor ventilation is insufficient. The temperature difference between inside and outside the workshop can reach 50 ℃. Therefore, the temperature gradient in the workshop during winter is very complex. When measuring the outdoor temperature of 1.5 ℃ from 8:15 to 8:35 in the morning, the temperature change in the workshop is about 3.5 ℃. In such a workshop, the machining accuracy of precision CNC machining machines is greatly affected by environmental temperature.
