1 Scope

This specification applies to the calibration of frame level and strip level with a graduation value of (0.02~0.10) mm/m.

2 Citations

This specification refers to the following documents. GB/T 16455-1996 Strip and frame level JJF 1001-1998 General measurement terms and definitions JJF 1059-1999 Measurement Uncertainty Evaluation and Representation Use of this specification should be done with the current valid version of the above cited documents.

3 Overview

The frame type and strip level are based on the principle of liquid level, and the horizontal displacement is directly displayed by the level bubble, and the measurement is relative to A universal angle measuring instrument with a slight tilt angle for horizontal and vertical positions; it can also be used to measure various machine tool guides Straightness, flatness and parallelism, correcting the level of installation and vertical position of the equipment. The outline structure of the frame level and the strip level is shown in Figure 1 and Figure 2. figure 1 figure 2
