GB/T 19362.2-2017 Test conditions for bridge-type milling machines—Testing of the accuracy—Part 2:Travelling bridge (gantry-type) machines
Basic Information
Scope
This part of GB/T 19362 specifies the requirements and methods for inspecting the geometric accuracy, working accuracy, and axis positioning accuracy of gantry mobile milling machines for general use and ordinary precision, as well as the corresponding tolerances. This part applies to gantry milling machines with a movable column and a fixed worktable. It does not apply to single-column and gantry milling machines with a fixed column and a movable worktable. It is suitable for accuracy inspection of machine tools, but not for operational checks of machine tools (such as vibration, abnormal noise, and creep of moving parts), nor for parameter checks of machine tools (such as speed and feed rate). These checks should be carried out before accuracy inspection. This part provides terminology for the main components of machine tools and names the axes in accordance with GB/T 19660-2005.
