introduction：（1）Measurement of bore The bore can be measured by checking the reference size on the outer micrometer with the inner diameter gauge，It is also necessary to measure the roundness and cylindricity of the bore。Burnt out 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 diameter of the bore at the opening is often reduced and the roundness is excessive，Butt bearing[bearing:bearing（“Bearin

introduction： 1. DCSIs a kind of“Distributed control system”，whilePLC (Programmable controller) Just a form of control“device”，Both are“System”with“device”The difference of。The system can realize the function and coordination of any device，PLCThe device only implements the functions of this unit。 2. In network，DCSThe network is the central nerve of the whole system，It is a high speed communication network with security and redundancy，The expansion and openness of the system are better。whilePLCBecause they basically work for individuals，Its in relation to something elsePLCOr the host computer to communicate，adopted

introduction：（1）Choice of abrasives The type of abrasive should be selected according to the base material and polishing requirements of the machined part、Shape and particle size，Polishing after testing is usually required（grind）The effect is final。 Usually, hard abrasives are used in polishing metal parts，Soft parts such as plastics are polished with a mixture of animals and plants and hard abrasives。When polishing surfaces that require high finish quality，Abrasive with a smooth shape should be used。The size of the abrasive should be larger than that of the inner hole of the part1/3Still young，But not too small.，To prevent holes from being blocked by abrasives。 To improve the finish effect and production efficiency，The right one should be chosen

introduction：Problems of carding machine before transformation The electrical control box is in disrepair，Internal element aging，There are frequent faults of short circuit and open circuit； Poor quality of output strip。Because Doffer speed control mode is unreasonable，Cause to start、The speed changes unsteadily during braking and Doffer fast/slow transition，The quality of the strips deteriorates； Low yield，Due to the poor stability of the machine，Raw strip weight unevenness and other reasons，The speed of the tin can not be increased，The output of carding machine is affected； The start-up process of the machine is noisy，Because of the high moment of inertia of the tin，Serious belt slippage during startup
