introduction：A gauge capable of forming an accurate Angle between two flat surfaces that have coalescing properties。Using the Angle measuring block attachment, the measuring blocks with different angles are formed into the required angles，It is often used to verify the Angle template and universal Angle ruler，It can also be used to directly measure the Angle diagram of the workpiece[Two angular measuring blocks]For two Angle measuring blocks：in10°～79°A measurement Angle between them is calledⅠType Angle measuring block； in80°～100°occasionally4One measuring Angle is calledⅡType Angle measuring block。Angular measuring blocks are supplied in complete sets，points0level、1level、2level3Species accuracy,The allowable deviations of the measurement angles are respectively±3、±10and±30。 Son Songquan

introduction：one、Basic finishing technology 1.stentering(stentering) Tensioning is the use of cellulose、silk、The plasticity of fibers such as wool under wet conditions，The fabric width is gradually stretched to the specified size and dried，The process by which the shape of the fabric is stabilized，Therefore, it is also called finishing。Some processing such as scouring and bleaching of fabrics before finishing、Dyeing and other processes，Often subjected to meridional tension，Force the warp elongation of the fabric，Zonal contraction，And produce some other disadvantages，Such as uneven width、The cloth has uneven edges、Rough feel、Flat with aurora, etc。To make the fabric uniform and stable

introduction：High speed milling of hardened steel is an advanced machining technology，It is one of the effective hard milling techniques。For a long time，People have always used milling - grinding or milling—Electric discharge machining(EDM)The method of realizing the processing of the mold。Although EDM has process characteristics independent of workpiece hardness，However, the low material removal rate limits its application range。With the development of modern processing technology and the appearance of superhard tool materials，Milling instead of grinding、Milling insteadEDMEconomical mold processing has become possible，Remarkable economic benefits have been obtained in production。 Adopt hard milling technology

introduction： 1 introduction At present, the fine blanking process is more and more widely used in the manufacture of automobile parts(As CAM、Tooth plate and clutch plate, etc) 。Due to the high pressure of the fine stamping die, convex、The die gap is very small(0. 01～0. 02mm) , And the thermal effect in the fine blanking process、Friction and other reasons, It is difficult to guarantee the life of the fine stamping die, Lead to premature fine die damage or scrap。The cost of fine blanking die is generally that of ordinary blanking die5～10 times, And because of the fine blanking machine production efficiency is very high, Frequent mold changes due to low mold life will also reduce productivity,
