Granite square ruler

Granite right angle ruler is a measuring tool,abbreviated as angle ruler,and in some cases,it is also called a guiding ruler.According to the material,it can be divided into cast iron right angle ruler,magnesium aluminum right angle ruler,and granite right angle ruler.It is used to detect the verticality of the workpiece and the verticality of the relative position of the workpiece,and sometimes it is also used to draw lines.Suitable for verticality inspection,installation,machining positioning,and marking of machine tools,mechanical equipment,and components,it is an important measuring tool in the mechanical industry.Its characteristics are good stability and easy maintenance.

The granite square ruler is made of Jinan green stone material through mechanical processing and manual precision grinding.Black luster,structure,uniform texture,good stability,high strength,can be maintained under heavy loads and general temperatures,and has advantages such as non rusting,non magnetization,and unchanged shape.

1.After long-term aging,the internal stress of the rock disappears and does not deform,therefore.

2.Not afraid of acid and alkali erosion,not prone to rust,does not require oil,is not prone to sticking fine dust,maintenance is convenient and simple,and has a long service life.

3.There will be no scratches,not hindered by constant temperature conditions,and the temperature measurement accuracy can be maintained at room temperature.

4.Non magnetized,able to move smoothly during measurement,without any sluggishness,unaffected by moisture,and well balanced on a flat surface.
