Customer evaluation: the quality of the blades purchased this time is good, and the after-sales service attitude of Maanshan Yongzhou Machinery Technology Co., Ltd. is also relatively good. I asked a lot of questions and answered them patiently. The blade of the former machine was not used very fast, and the effect was not very good. It was not smooth enough. It was a headache for the later processing. Now a new blade has been replaced, and the ones that come out are relatively smooth and smooth. I hope we can continue to cooperate.
