How is the constant temperature machining of high-precision machine tool granite structural components achieved?
Implementation Principle of Constant Temperature Machining for High-Precision Machine Tool Granite Structural Components The thermal expansion coefficient of granite (such as Jinan Blue) is approximately 4.5e-6/℃. Although far superior to cast iron, a 1℃ temperature difference in a 1m component still causes about 4.5μm of deformation. Achieving micron-to-submicron precision machining must be realized through a…
