Non magnetization No-rust and anticorrosion Jinan/South Africa black Granite Mechanical part

Non magnetization No-rust and anticorrosion Jinan/South Africa black Granite Mechanical part

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 roughedgeswhich might  influence its measuring precision.
5.Non magnetization.                                    
6.Glossy surface  without sluggishness when the workpieces or tools are moving on it.
