The grating ruler is mainly responsible for displacement measurement. It is a high-resolution, high-precision, fully enclosed measuring instrument. It adopts the photoelectric conversion mode to achieve high efficiency and high speed.

Many customers who buy grating rulers cannot distinguish the difference between the accuracy and resolution of grating rulers. What we generally call 5UM, 1UM, 10UM, 0.5UM, etc. refer to the resolution of the grating ruler, which is equivalent to the scale of the grating ruler, just like the scale on an ordinary ruler. There is no definite value for accuracy. Under ideal conditions, the accuracy of the grating ruler can reach the resolution of the grating ruler. However, the accuracy will be affected by various factors and there will be corresponding errors. For example, the accuracy will be affected by the ruler stroke, the working environment, the parallelism of the installation, the temperature, etc. The parallelism of the installation will also have a certain impact on the accuracy of the grating ruler. However, as long as the installation is correct and the environment is not very harsh, the grating ruler can still achieve a very high accuracy. After all, the grating ruler is currently one of the most precise measuring instruments.

The specifications of the grating ruler for the No. 3 milling machine are 850*400MM, 5UM, and the specifications of the No. 4 milling machine are 900*450MM, 5UM. If you need a higher precision, you can choose a 1UM resolution. The higher the resolution of the grating ruler, the higher the precision.
