Do you know the quality inspection of grinding rod? Here I wanna to share my
method for you.
1. The quality and the dimension of the grinding rod manufactured by each
work shift are strictly inspected in line with the above standard. Only after
passing the inspection can the product be stored into the warehouse.
2. Five products are randomly selected from the products of each work shift
for hardness inspection.
If there is one unqualified product, the re-inspection is conducted by
choosing the product with the amount doubled.
If there is still the unqualified one, and the average value of all the
hardness values is compliant with the hardness requirement, then, we can say
this batch of products is qualified.
Otherwise, this batch of products is considered below the standard.
We can supply high quality grinding rod, you can contact us directly without
worry its quality.
