The basic forms are：wear、Severance、Plastic deformation。 The actual working situation of the mold is very complicated，Multiple damage forms interact，Wear promotes plastic deformation and fracture，The deformation of the statue increases the speed of wear and fracture。 1、wear Friction between the mold and the processed blank，Cause the mold surface material loss，The geometry of the mold is changed and cannot be continued in service，That is, wear failure。 The wear failure is manifested as cutting edge passivation、The edges are rounded、Plane subsidence、Surface furrow、Peel off、Mould sticking。 Influencing factor：Chemical composition and mechanical properties of mold materials and billets to be processed；

1、Axial sumNSKbearing[NSKbearing:Seiko Co., LTD（NSK LTD.）Be established in1916years，It is the first manufacturer to design and produce bearings in Japan。NSKThe function of the bearing fit is to makeNSKThe stationary ring and rotating ring of the bearing are respectively the stationary part of the installation part(Usually a bearing seat)And rotating part(Usually an axis)Solidify together，Thus, the basic tasks of transferring the load in the rotating state and defining the position of the moving system relative to the stationary system are realized。]Selection and control of room tolerances：NSKbearing[NSKbearing:Seiko Co., LTD（NSK LTD.
In CNC turning，The program runs through the entire machining process of the part。Because each persons processing method is different，The preparation process is also different，But the ultimate goal is to improve the production efficiency of CNC lathes，Therefore, it is particularly important to choose the most reasonable processing route。This article will start from determining the cutting route、Choose the rightGOrder and other details to proceed,The programming method in NC turning is analyzed。 one、Analyze part drawing Analysis of part drawings is the primary task in process preparation，Directly affect the preparation of parts
The basic use method of electromagnetic clutch 1、Connecting and disconnecting action：A clutch is installed between the driving part and the starting part，There is no need to stop the drive，The starting point will be connected and disconnected according to the necessary reaction 2、 High-frequency operation：Intermittent operation in a fast cycle、Use the motor over and over againON、OFFThe frequency provided is limited、So use the clutch、Make it react quickly、High precision braking 3、 Position reckoning：Stationing in the measured position or quantitative transmission depends on high-precision positioning devices、Positioning can be achieved by using the clutch
