What level of machining accuracy can the granite base of a five-axis ultra-precision machine tool achieve?
Combining industry general standards, machining processes, and the operational requirements of five-axis ultra-precision machine tools, accuracy levels are divided into three major categories: basic geometric accuracy, form and position tolerances, and surface quality. These levels further distinguish indicators for rough machining, precision machining, and ultra-precision grinding stages, while marking conventional industry thresholds. Machining Accuracy Levels…
