In this aspect of sheet metal processed parts, today I will mainly answer two related questions, which are specifically: Question 1: What are the machines and equipment used in Kunshan sheet metal processed parts? Question 2: In the case of sheet metal machined parts in Kunshan, if there is a phenomenon of vibration knife, what is the reason? Now that the questions have been asked above, I will answer these two questions in the following, so that everyone can understand them clearly and master them well. There are a lot of machines and equipment used in Kunshan sheet metal processing parts, because there are many procedures, mainly lathes, milling machines, planers, drilling machines, boring machines, broaching machines, grinding machines and polishing machines. These machines and equipment can be subdivided. However, due to the limited length of the article, we will not elaborate here. Kunshan sheet metal processing parts, which also include sheet metal processing, generally use punches, bending machines, cutting machines and so on. And mold processing, in addition to the above, there are EDM equipment, sawing machines and laser marking machines. In addition, in the early and post processing of sheet metal processed parts, heat treatment equipment and electroplating equipment are also used. The main reasons for the phenomenon of knife vibration in Kunshan sheet metal machining parts are as follows: Cause one: The main shaft bearing clearance is too large, or the workpiece surface is too rough. Reason two: In machine tools and tools, resonance has occurred.
