Because the computers and electronics that enable us to program and control CNC machine tools are typically housed in a protective cabinet, we sometimes forget that they are still subject to damage if heat builds up or debris finds its way into the enclosure. In fact, a widely accepted rule of thumb is that the rate of failure for electronic devices is cut in half for every 50º F (10º C) decrease in temperature.
Summer is upon us and, in most parts of the country, that means heat and humidity are on the rise. For CNC machine shops, increasing temperatures and humidity levels are more than a physical discomfort. They represent a real danger for the electronic components of machine tools, computers and other shop equipment.
