introduction： 1)One slow, two fast, three steady。At the beginning of pouring，Especially when the liquid metal is just touching the foam，A large amount of gas produced by the gasification of the pattern material，When the straight gate is not filled or the static pressure of the metal liquid at the beginning of pouring is less than the gas pressure of the polystyrene decomposition product，Pouring too fast is easy to produce choking phenomenon，Make liquid metal splash。To avoid this phenomenon，At the beginning of pouring, the method of slow pouring can be adopted，After the pouring system is filled with liquid metal，Can increase the pouring speed，The sooner, the better，However, the rule is that the sprue cup is filled with metal and does not spill。In the late stage of pouring，When the liquid metal reaches its shape

introduction： Transport vehicles for short distance transportation of trackless trains。Tractors and trailers belonging to handling vehicles do not include cars driving on the road、Tractors and trailers。A tractor is used to tow a trailer，It is sometimes used to pull other equipment，Towing aircraft or air cushion handling devices, etc。The trackless train evolved from the narrow-gauge rolling stock，Its transport routes can be changed，It has greater flexibility，And has been developed into a driverless handling system。The structure will be complex in the transport vehicle、The driving part with high cost and the bearing part with simple structure are made into tractor and trailer respectively，And form a train to run，Can improve drive part turnover

introduction：The raceway sound is due toinabearing[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。]When rotating, the rolling element rolls in the raceway and generates a smooth and continuous noise，It attracts attention only when its sound pressure level or tone is extremely high。In fact, the sound energy stimulated by raceway sound is limited，As in normal circumstances，High quality aligning ball bearing track sound

introduction： Fengye Mall clutch introduces you to ball screw testing and maintenance。 When the CNC machine has a large reverse error、Positioning accuracy is unstable、When theres a knife mark across the quadrant，First check the lead screw system for gaps。The detection methods are:Place the dial indicator with the steel ball in the center hole of one end of the lead screw In the，Measure the axial movement of the lead screw，Another dial gauge measures table movement。Turn the lead screw forward and backward，Observe the values reflected on the two dial gauges，Determine the fault location according to the different value changes。 For example, when the dial indicator measuring the lead screw rotates positively and negatively, the pointer does not
