1、 Precision machining manufacturer Rigidity of shafting

　　 Mainly determined by the structure of the shafting ， Especially the rigidity of the medium between the main shaft and the main shaft sleeve 。 Increasing the spindle diameter increases rigidity ， But the structural size of the shafting is increased 。 High precision parts customization ， If the spindle is designed as a stepped shape ， Generally, the rear journal is the front journal 0.7~0.8 Times 。

　　2、 Precision machining manufacturer Flexibility of shafting

　　 Mainly determined by the spindle 、 Shape and structure of spindle sleeve and properties of Middleware 。 For the cantilever shafting, the cantilever amount should be reduced as much as possible ， Best choice 4 Tapered spindle No ， Select the large end diameter as the small end diameter 1.5~2 Times 。 For the rolling bearing shafting, the preload is applied to the bearing to adjust the friction torque 。 Choose a good lubricating oil for sliding shafting 。 Reasonable selection of interference for dense ball shafting 。 Pneumatic 、 Gas control for hydraulic shafting 、 Mass and flow of liquid 。

　　3、 Precision machining manufacturer Stability and life of shafting

　　 Mainly depends on the wear condition of the shaft system in use 。 Machining website requires reasonable selection of spindle and sleeve 、 Wear resistant materials such as axle pads ， Determine reasonable hardness ， And in Processing technology Necessary wear resistance and stability treatment shall be carried out in ， If multiple aging treatment is adopted 、 Cooling treatment after quenching to ensure the stability of accuracy of main parts of shafting ， It is also required that the vibration of shafting in service environment is small ， Small temperature change ， No harmful gas ， Require user Science 、 Reasonable use 。 The vulnerable parts in the shafting mechanism shall be easily removed and replaced ， And it can realize the adjustment and compensation of precision 。

　　4、 Precision machining manufacturer Rotary accuracy and speed of shafting

　　 The rotation accuracy of shafting mainly depends on the accuracy of main shaft and main shaft sleeve and the medium between them （ Component ） Performance ； Determination of rotation speed Mainly determined by the spindle Media between spindle sleeve ( Component ) Performance And quality ， As well as the size and distribution of shafting load
