Granite T Slot  Surface plate , also known as granite t slot surface plate , is made of high-quality "Jinan Qing" stone material through mechanical processing and manual precision grinding. It has the advantages of high precision, long service life, acid and alkali resistance, and is not easily deformed. It is suitable for precision inspection, precision measurement, and precision marking work in mechanical processing and component manufacturing industries.

　　Characteristics of granite T-slot  surface plate :

　　1. 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.

　　2. No scratches will appear, not hindered by constant temperature conditions, and can maintain temperature measurement accuracy at room temperature.

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

　　4. Rock undergoes long-term natural aging, with a uniform organizational structure, extremely low coefficient of linear expansion, complete disappearance of internal stress, and no deformation, resulting in high accuracy.

　　5. The granite t slot surface plate  has good rigidity, high hardness, and strong wear resistance.
