For parts with scale marks, the scale lines, numbers and marks should be accurate, uniform and clear. The handwheel rim and the operating handle should be polished. If chrome plating is used, it should be matte chrome plating.
Springs that affect the performance of bolt former machine should be subjected to performance tests such as force measurement.
5 Assembly quality
bolt maker machine should be assembled according to the assembly process regulations. After assembly, the movements of each mechanism should be flexible, accurate and reliable.
Important fixed joints that affect the accuracy and transmission system of bolt making machine or are subject to impact force should fit tightly. After tightening, check with a 0.05mm feeler gauge (for non-important fixed joints that are generally not subject to force, use a 0.08mm feeler gauge for inspection). Only partial insertion of the feeler gauge is allowed, and the insertion depth is not more than 20mm. The cumulative length of the insertable part should generally not exceed 10% of the detectable circumference.
