introduction：abbaRail maintenance abbarail(ABBALinear)It is a kind of linear slide produced by ** Standard Linear Technology Co., LTD。This kind of guide rail is slowly popularized in the major machinery industry，For such a hot rail if you dont know how to maintain it that doesnt make sense，Next Xiaobian will take you to understand it。 abbaGuide rail cleaning and maintenance： rail、The linear shaft is one of the core components of the equipment，Its function is to guide and support。In order to ensure that the machine has a high processing accuracy，Required guide、The straight line has high guiding accuracy and good motion stability。The device is running，Due to the workpiece in the processing will produce a lot of corrosive dust and smoke，These smoke and dust are deposited in large quantities on the rail for a long time、Straight axis surface，It has a great influence on the machining accuracy of the equipment，And it will form corrosion points on the surface of the linear axis of the guide rail，Shorten the service life of equip

introduction：abbaGuide agents teach you how to distinguish between true and false abbarail：A groove or ridge made of metal or other material，endurable、immobilization、A device that guides a moving device or device and reduces its friction。A longitudinal groove or ridge on the surface of a guide rail，For guidance、Fixed machine parts、Special equipment、apparatus。Guide rail is also called slide rail、Linear guide、Linear slide，Used for linear reciprocating motion，Has a higher load rating than linear bearings， At the same time can bear a certain torque，High precision linear motion can be achieved under high loads。Guide rail is mainly divided into two categories: roller guide rail and ball guide rail。 Here are a few simple ways to tell，Not absolutely，For reference only： 1---Slide rail Early stage（At least09Years ago）Arc grinding marks are visible on the upper surface of the slide rail，Bottom ground on both sides，The indentation in the middle is black without grinding。 2---Sliding block The unground part of the upper surface of

introduction：The master controller generally consists of a contact system、Operating mechanism、pivot、Gear reduction mechanism、CAM、The shell is composed of several parts。 Its operating principle is the same as that of the universal transfer switch，All rely on CAM to control the closing of the contact system。But compare that to the universal switch，It has a larger contact capacity，There are also more maneuvering gears。 The combination of different shapes of cams can make the contacts act in a certain order，The CAM Angle is determined by the structure of the controller，The number of cams depends on the requirements of the control line。 Because the control object of the master controller is the secondary circuit，So the working current of the contact is not large。The group of cams is combined with the corresponding contact system through the screw，The rotating shaft can be directly connected with the operating mechanism，It can also be connected with the reducer。If the number of circuits being controlled is

introduction：What is a CAM controller？ Also known as contactor controller。Because it moves、The operation principle of the static contact is very similar to that of the contactor。As for the difference between the two，Only different from the CAM controller is manually operated，And can be replaced by most of the purpose of electrical appliances，The contactor system has an electromagnetic attraction to realize the remote operation mode of driving，The number of contacts is small。 Its a large control appliance，Its also multi-gear、multicontact，By hand，Turn the CAM to make and break the contact switch through the high current。CAM controller is mainly used to control the start of small and medium-sized winding rotor asynchronous motor in lifting equipment，stop，Speed regulation，Reversing and braking，It is also suitable for other electric drive occasions with the same requirements。 The working principle of CAM controller： The shaft of the CAM controller is covered with a lot of sleeves（Generally speaking12slice
