Purposes: of cast iron feet of vertical parallel box combination, applies not perpendicular to the inspection between the high-precision machinery and equipment, inspection and machine is an important tool used to check the verticality between the various machine internal. 


 Feet of cast iron: GB6092-85 standard manufacturing materials HT200-250, for perpendicularity, parallelism detection, can be measured as a 90 ° benchmark.
