GB/T 19362.1-2003
ActiveMachine tools--Test conditions for bridge-type milling machines--Testing of the accuracy--Part 1:Fixed bridge (portal-type)machines
龙门铣床检验条件 精度检验 第1部分:固定式龙门铣床
Application Summary AI generated
This standard specifies the geometric and practical accuracy tests for fixed bridge (portal-type) milling machines, including permissible deviations for key parameters like spindle runout and guideway straightness. It is applied by machine tool manufacturers and quality inspectors during final acceptance and periodic verification of large-scale bridge-type milling machines used in heavy machinery, aerospace, and automotive industries. The standard ensures consistent machining precision for components requiring high flatness and parallelism, such as engine blocks and structural frames.
