I. Why Modern Precision Workshops Still Cannot Do Without These Three Granite Measuring Tools II. Their Truly Irreplaceable Core Advantages Far superior temperature stability compared to steelThe coefficient of linear expansion is only about 1/3 to 1/2 that of steel, so workshop temperature fluctuations have minimal impact on precision. No deformation, no release of internal…
