The environment temperature and humidity requirements. Numerical control lathe generally requires the use of environmental temperature, to ensure the working accuracy of machine tools, general requirements temperature 20 degrees Celsius. A lot of practice has proved that the summer high temperature period, numerical control system failure rate increases greatly, is very easy to cause collision accident. Moist environment and reduces the reliability of CNC lathe operation, thus dehumidification measures dealing with numerical control lathe environment, in order to avoid short circuit and wrong operation cause nc system, the collision accident. At the same time, it also requires the numerical control lathe from forging equipment vibration source, away from electromagnetic interference, away from the welding machine, away from the wire-cut machine and electric machine tools, such as edm machine.
