introduction： Mold is an important tool used in the process of tire vulcanization，The mold is inevitably subject to rubber during use、Combined deposition contamination of the compound and the release agent used in the vulcanization process(The main pollutant is sulfide、Inorganic oxide、Silicone oil、Carbon black)，Repeated use will cause some pattern contamination dead zones。therefore，The mold must be cleaned regularly to ensure the cleanliness of its surface，In order to ensure the quality of the tire and the life of the mold，In view of this，The development of tire mold cleaning technology is concerned by the industry。 There are two traditional cleaning methods for tire molds： 1.1Mechanical cleaning

introduction：bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The metallurgical quality of the material used to be affectedINAThe main factors of early bearing failure。Following metallurgical technique（For example, vacuum degassing of bearing steel）The improvement of，The quality of raw materials has improved。The proportion of raw material quality factor in the failure analysis of the whole eccentric bearing has decreased significantly，But it

introduction：In the past，Machining a sawtooth on a part requires an additional operation on a milling machine or broaching machine。This requires a separate setup on an additional machine，Incur additional labor costs（For milling machine or broaching machine operators），Of course, there is additional handling、Movement and possible temporary parts storage between processes。In addition，Before the zigzag machining，Parts may require intermediate cleaning operations。 If you are one of the companies that uses sawtooth machining as a separate operation，Then you will surely be pleased to learn that there is now a serrated processing razor，It can be used inCNCDriving on lathe

introduction： First of all，Impact sound of rolling element and its control method Larger type of ball bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Or cylindrical roller bearings running at low speed under pure radial load，Because the centrifugal force of the rolling body is small，The rolling element in the non-load zone will impact the cage or raceway and make noise。But as the RPM increases，this
