introduction：Screw screw can do？ Is made by the feeding sectionL1、Compression sectionL2Sum metering sectionL3Make up，It is a cylinder with a spiral groove cut on its surface or a cone with a spiral groove cut on a cone，The rubber material gradually becomes a linear moving element with the rotating motion。How it works：The screw is moved in a straight line towards the head，And fit into the fuselage，Heat generation by compression、Softening stirring，Mixed compound。Its the heat extrusion plasticized part，One of the cores of plasticizing machinery。 Scope of application：For injection molding machine screw type、Bakelite screw、Rubber machine。 ?Feed section parameters： Selection of spiral lift Angle，The best spiral Angle is45°，however，It is difficult to choose the best spiral Angle according to theory，This is because of the coefficient of friction during the extrusion process、Extrusion pressure is an uncertain factor。And there is the influence of shuttle width，Plus from the machine tool processing difficulty to consider，

introduction：Working principle of ball screw nut？ The ball screw nut pair is a commonly used transmission device for converting rotary motion into linear motion in CNC machine tools。It replaces the sliding in the screw nut pair with the rolling of the ball，Low friction，It has good performance。 Make up：Mainly by the screw、nut、Balls and raceways（baller）、Nut seat, etc。 1.Working principle：The screw rod and nut are machined with spiral grooves，When fitted together, they form spiral raceways，And fill the raceway with balls。The ball rolls along the raceway，And through the return bead tube for a cyclic motion。Both ends of the bead tube also play the role of bead blocking，In case the ball falls off the raceway。 2．peculiarity： .High transmission efficiency：Mechanical efficiency up to92%~98%。 .Low friction：It mainly uses the rolling of the ball to replace the sliding of the ordinary screw nut pair。 .Axial clearance can be eliminated：Also due to the role of the ball，The rigidity of the system is improved。The gap can be eliminated a

introduction：What are the types of nuts？ A nut is a nut,A part screwed together with a bolt or screw for fastening，An original that is required for all manufacturing machinery.There are many kinds of nuts,We commonly have national standards,UK standard,American standard,Date nut.Nuts vary according to material,Split into carbon steel、High strength、Stainless steel、Plastic steel and other major types.According to the product attributes corresponding to different countries of the standard number is divided into ordinary、non-standard、（The old）National standard、New national standard、American system、British system、German standard。Different in size,The thread is divided into different specifications. General national standard、Standard of virtueMexpression(Such asM8、M16)，American system、The English system uses fractions or#Presentation specification（Such as8#、10#、1/4、3/8） Nuts are parts that hold mechanical devices together,Threaded through the inside,Nuts and screws of equal size，To be connected together，Such asM4-0.7The nut

introduction：Pneumatic actuator that converts the pressure energy of compressed gas into mechanical energy。There are two types of cylinders for reciprocating linear motion and reciprocating swing（See picture[Type of cylinder]）。The reciprocating linear movement of the cylinder can be divided into single action、Double acting、Diaphragm type and impact cylinder 4Kind of。①Single acting cylinder：Only one end has a piston rod，Air is supplied from the piston side、Output force in one direction，Return by spring or self weight。②Double acting cylinder：Alternate air supply from both sides of the piston，Output force in one or both directions。③Diaphragm type cylinder：Replace the piston with a diaphragm，Output force in only one direction，Spring reset。It has good sealing performance，But the trip is short.。

introduction：The particulate emission of an engine is closely related to the oil consumption，The oil consumption of the engine is largely determined by the amount of leakage between the cylinder and the piston ring。The surface quality of the cylinder has an important influence on this。The German Volkswagen company relies on emery-Liquid injection-Finishing honing method（carborundum-FGmethod）A new processing method was developed，The main advantages are reduced oil consumption and reduced wear on piston rings and cylinders。 Status quo of cylinder processing technology The final processing of cylinder barrel of automobile engine is almost without exception carried out by honing technology。According to the geometry of the workpiece and the characteristics of the tool kinematics，Cylinder processing technology involves a long stroke-interior-Circular honing。In this process，The rotary motion and moving motion of the tool are superimposed together，This superimposed tool movement creates a very special cross groove structure on
