Using a square ruler to detect the verticality error of the moving parts of the machine tool
The feed motion of the moving parts of the machine tool includes three directions of vertical movement - vertical direction, vertical direction and horizontal direction, such as: horizontal boring machine, milling machine, etc. Some machine moving parts have only two perpendicular movements, such as ordinary lathes and planers. In machine tool repair and accuracy testing, the most commonly used is the use of a square as a measurement reference to detect the verticality error between moving parts. Figure 1 shows the horizontal boring machine table with a square and a dial gauge.
