introduction：Lead screw processing，The center hole is the positioning reference，But because the lead screw is flexible，Poor rigidity，Easily deformed，Appearance straightness、Machining errors such as cylindricity，It is not easy to meet the technical requirements of shape and position accuracy and surface quality on the pattern，Auxiliary supports must also be added during processing。Contact the outer round surface with the tool holder，Prevent workpiece bending and deformation caused by cutting forces。meanwhile，In order to ensure the accuracy of the positioning reference，In the process, three grinding operations of the center hole were arranged。 Because the lead screw thread is the key part，The grinding allowance is made to prevent cracks caused by quenching stress concentration and to avoid the deformation of the thread on the full length

introduction： Hefei electromagnetic clutch said，To ensure the normal operation of the electromagnetic clutch，It must be regularly maintained and basic maintenance by a professional eye。 First of all，Pay attention to check the operation of the equipment，Once you feel that the rotating part is not flexible enough，It is necessary to check whether it is because of the lack of lubricating oil。secondly，The length of the armature should be checked regularly。The clutch is in the process of operation，Because youre constantly getting friction from the profile，The length of the armature also increases;In the process of inspection，If you find that the length of the armature is not enough，Then adjustments must be made immediately;
