The price of the blade

In the case of the same material and processing technology, the price of the blade cutter is almost the same. Customers can first understand the market price of raw materials used in the production of shearing machine blades, and then compare the prices of shearing machine blade manufacturers. If the quotation is lower than or slightly higher than the price of the material, then it is shoddy.

The production process

In addition to the material, that is the processing technology in the production process. In the production of shearing machine blades, each process is very important, and the most important thing is heat treatment, and a set of qualified shearing machine blades must be quenched at least twice before the blade hardness can be purchased inside and outside. It can be tested with a metal hardness tester to see if the hardness is up to standard and consistent.

Accuracy

The parallelism of the blade of the general shearing machine is 0.03mm, and the thickness of the full length of the blade can not exceed 0.03mm. To achieve such precision, it can be regarded as a set of qualified shearing machine blades. After the purchase, the measuring tools can be used to compare the errors of the two ends of the single piece, and then measure the accuracy of the whole set of blades one by one, and then see if there is no gap at the joint, and whether the touch is flat or not.

Warranty

A set of high-quality qualified shearing machine blades, at least one or two years, up to three or five years. Therefore, when purchasing, you must ask about the after-sales guarantee and sign the agreement.
