MitsubishiFXWhich products in the series have pulse output function?How to select? 1、 Transistor output types are programmable such as FX1S-*MT(max 100K) FX1N-*MT(max 100K) FX2N-*MT(max 20K) 2、 Pulse output module FX2N-10PG-E FX2N-1PG-E 3、 Position control unit FX2N-10GM FX2N-20GM The transistor pulse train is mainly used in simple position control module,
1.introduction Machinery manufacturing as the basis of the entire industry,Moving towards high precision、The rate of、The direction of intelligent and flexible development。grinding、Super finishing(For short“Grinding supermachining”)It is often the ultimate processing link of mechanical products,The quality of its machining directly affects the quality and performance of the product。As one of the basic parts of machinery industry 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,To reduce the power transmission process
The selection of cutting tools and the determination of cutting parameters are important contents in NC machining technology,It not only affects the processing efficiency of CNC machine tools,And directly affect the quality of processing。CAD/CAMDevelopment of technology,It can be used directly in CNC machiningCADThe design data becomes possible,Especially the connection between microcomputer and CNC machine tool,Make design、The whole process of process planning and programming is completed on the computer,It is generally not necessary to output special process documents。 now,A lot ofCAD/CAMAll software packages provide automatic programming capabilities,These software usually prompts the process planning in the programming interface
Rolling 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。]Combinatorial design 1bearing[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,
NSKbearing[NSKbearing:Seiko Co., LTD(NSK LTD.)Be established in1916years,It is the first manufacturer to design and produce bearings in Japan。NSKThe function of the bearing fit is to makeNSKThe stationary ring and rotating ring of the bearing are respectively the stationary part of the installation part(Usually a bearing seat)And rotating part(Usually an axis)Solidify together,Thus, the basic tasks of transferring the load in the rotating state and defining the position of the moving system relative to the stationary system are realized。]Use water-soluble cutting fluid,Users must work hard on machine maintenance and management,To control corrosion,Or even almost eliminated
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 outer packaging is clear In general,Bearings of the factory brand[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 are opposite each other on the shaft
By base code、The prefix code and the post code are composed。 Base code representationFAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]Basic type of、Structure and size。 Prefix code representationFAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]Parts are placed before the base code。 Post-code representationFAGbearing[FAGbearing:The main shaft bearing is made up of real
In the grinding process,The workpiece surface layer will be subjected to the cutting force of the grinding wheel、The force of compression and friction。Especially the role of the latter two,The surface layer of the workpiece forms a strong directional plastic deformation layer and work hardening layer。These metamorphic layers must affect the surface layer residueNSKImported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing,ikobearing,fagbearing,Of good quality,Of course, the price is not cheap。]Change of stress。 (1)Cold plastic deformation layer In the grinding process,One particle per moment
1.Frictional compatibility The property of preventing adhesion and boundary lubrication when the bearing diameter is in direct contact with the bearing bush。The material factors that affect the friction compatibility of friction pairs are: (1)The degree of difficulty in forming alloys in metallurgy。 (2)Affinity of material to lubricant。 (3)Friction factor of the auxiliary material in the non-lubricated state。 (4)Microstructure of materials。 (5)Thermal conductivity of the material。 (6)The size of the surface energy of the material and the characteristics of the oxide film。 2.embedability The material allows foreign hard particles in the lubricant to clamp in and prevent scratching or scratches(and
