introduction：It can be found in the processing of threaded holes of different materials，For dense material、Materials with higher strength（steeliness）On the threaded hole，Due to its roughness、High rigidity and strength，The bolts used can be turned in and out multiple times，The screw hole is not easily damaged；And for the threaded holes on the aluminum alloy parts，Its roughness and strength are low，After repeated screw in and out of the bolt，Screw holes are easily damaged，Thus affecting the use of the workpiece。The screw hole on the aluminum alloy workpiece can be better prevented from being damaged by using the extruded tap。 Due to aluminum alloy die casting surface1mmThe following are prone to porosity，So we use drilling、Tapping and other conventional addition

introduction：Rolling ball 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。]With its low friction resistance、Starting sensitivity、High efficiency、High rotation accuracy、Simple lubrication、It has many advantages such as convenient replacement and is widely used in production and life。But because of its high manufacturing precision requirements、Complicated process，At present, the standard rolling bearings are produced by special aircraft，And by professional

introduction：In machine building，In addition to the use of a cylinder and an inner circle as a matching surface，Cone and inner cone are also commonly used as mating surfaces。Such as，The fit of the main shaft hole and the center of the lathe；Cone hole and center of tailstock sleeve、The fit of drill taper shank, etc。The cone has a tight fit with the inner cone，Easy disassembly，Multiple disassembly can still maintain accurate centering effect and other advantages。 There are four ways to conical the surface：Rotating small drag plate method、Offset tailstock method、By the ruler method and the broad knife method。 one、Rotating small drag plate method（Small knife rest inversion method） method：According to the coning Angle of the part（2

introduction：1。Occipital position-----The cavity protrudes the sealing part of the parting surface ； 2。Penetration bit-----Vertical direction of front and rear molds（Usually have3-5Exit Angle）The tight part 。 Occipital yesPLIt occurs when a bit jumps，For better sealing（Guard against criticism），So pull it out horizontally。 The one that goes straight down is the piercing，Easy to wear，FITIts a little bit of trouble，It is easy to leak glue from the insertion position and produce a batch front。 So a major principle of mold parting is：Never Pierce anything you can touch。 The face of the long one is occipital，The one on the side is the penetration position。 row-bit------Sliding block
