introduction：In mold making and model making，What kind of materials do you use？Be metal、Plastic or wood？In this way，There are also differences in the molds and models manufactured：Quality must be checked。Molds and models can be inspected in three dimensions。here，It is ideal to use a horizontal arm detector。This instrument has a large detection range。merely，If first is the natural mold andCADThe data was used in a short time，Then you use the detector is really there。 Carl.Zeiss uses the horizontal armCarmetThe detector gives you the possibility to make molds and models：Carmet check

introduction：Oil seal is used to seal oil（Oil is the most common liquid substance in the transmission system，Also refers to the general meaning of liquid substances）Mechanical element of，It isolates the parts of the transmission parts that need lubrication from the output parts，So the oil doesnt leak。Static seal and dynamic seal（General reciprocating motion）Using a seal is called a seal。The representative form of oil seal isTCOil seal，This is a rubber fully covered double lip oil seal with a self-tightening spring，Generally speaking, the oil seal often refers to thistcSkeleton oil seal。 What is the material of the oil seal？ The oil seal is rubber。The oil seal is mainly used in the joint of two lubricating parts，Prevent oil from seeping out，Like crankshaft

introduction： Abstract: 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。]Shell parts require high dimensional accuracy，And visible position tolerance requirements，So after the mold is formed，The dimensional accuracy is achieved by shaping process，At the same time, the end plane of the part meets the requirements of form and position tolerance。Shallow drawing for flange parts，The holder ring is used as a shallow drawing punch
