As we all know, materials will have thermal expansion and cold contraction. In precision machining, the problem of processing temperature must not be ignored! Temperature difference is the enemy of accuracy. If we don’t care about the important issue of processing temperature, how to discuss accuracy? Because most of the machine combination components are steel and cast iron, the shape and length will change according to the room temperature and the heat generated by the machine itself.<\/p>
