introduction：For high speed milling we will have to change the machining programming strategy。Here from the use ofCAMThe system provides some tips and find some methods。 High speed millingNCThe programmer must change the entire processing strategy to produce safe、Efficient and accurate tool paths and ideal surface accuracy。Therefore, it is very important to carefully consider each processing factor in the processing process，bestCAMThe system has such an analysis function。 Because the feed speed and spindle speed are very high in high-speed milling，The programmer must know in advance how the tool cuts the material。In addition to using smaller stepping sums

introduction：Aseptic packaged food，It means to make food sterile before packaging，Packed with sterile materials，Foods that do not require reheating to kill bacteria。International food hygiene regulations on food preservatives are strict，And the food tends to be low sugar and low salt health tendency；And the general food itself is poor storage。Therefore, aseptic packaged food is developing rapidly in the world，It preserves the flavor of the food，Save energy。The proportion of aseptic packaged food in the world is increasing year by year，Push the packaging material、Packaging machinery and equipment corresponding rapid development。 Aseptic packaging equipment for food Aseptic packaging equipment for food，By food sterilization device、Sterile packing machine or sterile

introduction： abstract:Introduced the adoptionSBRWhen treating beer wastewater，Organic matter degradation processCODwithDOCorrelation of。The test results show that，Such as changing the concentration of organic matter in the water、Aeration rate or initial mixed sludge concentration，In the process of organic degradationDOThere is a slow downward trend，At the same time，CODIt is degraded at a high rate。After the organic matter reaches the degree of difficult degradation，DOsurge，This marks the end of the reaction process。In addition，Due to floodingCODDifferent concentration，At the same aeration rateDOBig difference，Can start withDOThe size of the water as predicted

introduction：This molding method can eliminate melt cracks in plastic parts、interstice、Defects such as cracks and micro-porosity，And can control the arrangement of reinforcement fibers it uses main、Auxiliary two injection units and a double wound mold。Working hours，The main injection unit pushes the melt through a wound overfill mold cavity。Excess material is fed into the auxiliary injection unit through another gate，The auxiliary injection screw retreats to accept excess melt in the mold cavity；Then the auxiliary injection screw moves forward to inject the melt into the mold cavity，The main injection unit accepts excess melt in the mold cavity。The main、The injection unit is pushed and pulled so repeatedly，The vibration shear flow of the melt in the mold cavity is formed，When the melt near the mold wall is solid
