1. The perpendicularity between the main shaft of the piercer equipment and the workbench shall meet the requirements of technical specifications. The commonly used measurement methods are three-point method and dihedral angle method.
2. When testing the verticality, it is necessary to ensure the stability and reliability of the equipment foundation and support points to avoid the influence of external factors on the test results.
3. When testing the verticality of the piercer equipment, high-precision and sensitive testing instruments and related tools should be used to ensure the accuracy and reliability of the test results.
4. The verticality test results of the piercer equipment shall meet the requirements of the equipment manufacturer or technical specifications. If the test result does not meet the requirements, it should be adjusted and calibrated in time.
In a word, the requirement of verticality in the acceptance of piercing machine equipment is to ensure the accuracy and stability of the equipment, so as to ensure the working efficiency and production quality of the equipment in use.
