ave elongated 1pm, the ultra-precision machining and j-1 processing in the machining accuracy are generally micron, submicron or higher precision, and therefore, processing zones must ensure high stability soup.

    For the ultra-precision machining must be under strict multi-temperature conditions that not only put the machine room should i keep a warm, but also to take special measures for the thermostat on the machine. For example, a foreign laboratory a biaxial ultra-precision lathe installed in the rhumb set things j, machine outside cover with a transparent plastic cover, the cover features a tubing, the entire machine jet heated oil flow, pro
