introduction：Ball screw machining Ball screw is a precision transmission element，Widely used in CNC machine tools。The machining accuracy of ball screw is higher than that of sliding screw，The process is divided into five stages：Preheating treatment、Rough finish、semi-finishing、Finishing and finishing stages。The surface of the lead screw thread is composed of two arcs，The grinding wheel during fine grinding is corrected with special corrector。To eliminate internal stress，Arrange four heat treatment processes。

introduction：ABBABall screw these knowledge，A foreign country bombs a country and no one knows。ABBAThe ball spline uses a ball mounted in the outer cylinder of the spline，In a rolling groove of precision grinding，Smooth scrolling on one side，One side of the transfer torque，It is an epoch-making linear motion system。ABBAThe ball spline is different from the traditional construction，Because a single splined outer cylinder can be pre-pressed，therefore，It can be used in places where the vibration impact load is too large，Places that require high positioning accuracy，And where high-speed performance is needed，Play an effective role。meanwhile，Even when used instead of linear ball bushings，Because of the same situation in the axle diameter

introduction：In most operating conditions,Rolling bearings are used with appropriate clearance。Depending on the purpose，There are also bearings when installing，Prestressing the bearing internally，So that the bearing can be used under negative clearance，This method of use is called pretightening。Most of them are like angular contact ball bearings and tapered roller bearings，Apply two sets against each other、Bearing with adjustable clearance。If the preload exceeds the required limit，Will cause abnormal fever，Friction moment increase，Fatigue life decreases and so on。therefore，To fully study the working conditions、Preload purpose to determine the preload force。Purpose of rolling bearing preload，The main purposes and typical examples of preloading are shown below：(1) The diameter of the shaft

introduction：Bearing steelIts used to make ball bearings、Steel for rollers and bearing rings。Bearing steel has high and uniform hardness and wear resistance，And a high elastic limit。Uniformity of chemical composition of bearing steel、Content and distribution of nonmetallic inclusions、The distribution of carbides and other requirements are very strict，It is one of the most demanding steel grades in all steel production。1976International Organization for StandardizationISOIncorporate some common bearing steel numbers into international standards，The bearing steel is divided into：Fully quenched bearing steel、Surface hardened bearing steel、Stainless bearing steel、High temperature bearing steel and other four categories total17Steel size。 Bearing steel performance requirements： In order to meet the above requirements for the performance of dynamic bearings，The following basic performance requirements are proposed for bearing steel materials： 1）High contact fatigue strength， 2）After heat treatment, it should have high hardness
