Introduction

Granite Straight Edge purposes:to measure straightness and flatness of the work piece and equipment installation.Flatness,straightness of machine table,guides and precision work.Granite straight edge material JinanQing,granite straight edge is black gloss,structural precision,uniform texture,good stability,high strength,and high hardness.Granite square foot is made of natural stone materials,precision reference measurement tools,instruments,precision tools,machine parts inspection,is an ideal base level,especially for high precision measurements. 

Features 

1.High precision  reliable stability resistant to deform and guaranteed accuracy under normal ambient temperature.

2.No-rust and anticorrosion.

3.Wear resistance long service life.

4.Any cutting or scraching for working surface does not bring about rough  edges which might  influence its measuring precision.

5.Non-magnetization.

6.Glossy surface  without sluggishness when the workpieces or tools are moving on it.
