The difference in coaxiality between testing machines

          Leading Testing MachineThe companyis a professional testing machine manufacturer. Leading Testing Machine has high requirements for the overall quality, stability, coaxiality, casting stiffness, sensors, and servo motors of the testing machine. Machines that fail inspection cannot be shipped out of the warehouse, and we cannot provide customers with testing machines with quality defects or damage their interests. Here, we will mainly explain the differences in coaxiality of testing machines!

1、   What is the allowable value of coaxiality according to the national standard? What is the coaxiality of the Li Ling testing machine?

According to the national standard GB/T16491-2008 for electronic universal testing machines, the allowable values for coaxiality of 0.5 level and 1 level precision testing machines are 12% and 15%, respectively. The coaxiality of testing machines from Li Ling Company is between 2% and 7%.

2、 What are the factors that affect the coaxiality of the testing machine?

1. Position and verticality errors of the main installation holes for the upper and lower crossbeams, base, and workbench;

2. Coaxiality error of screw and column;

3. The angle, flatness, and symmetry errors between the wedge-shaped openings of the upper and lower crossbeams and the clamp plates of the jaws.
