What should I pay attention to in the maintenance of the mechanical parts of the drilling, tapping and milling machine?

2020/08/26


Maintenance precautions for drilling, tapping and milling:


① Regularly check and adjust the axial clearance of the screw nut to ensure the accuracy of the reverse transmission and the axial rigidity;


② Regularly check whether the connection between the screw support and the bed is loose and whether the support bearing is damaged.




The high-speed electric spindle of CNC machine tools is a set of components, which includes the electric spindle itself and its accessories: electric spindle, high frequency frequency conversion device, oil mist lubricator, cooling device, built-in encoder, change device, etc. The rotor of the motor is directly used as the main shaft of the machine tool, and the housing of the main shaft unit is the motor base, and cooperates with other parts to realize the integration of the motor and the main shaft of the machine tool.


Drilling, tapping and milling machine series are mainly used for drilling of flat plates, flanges, discs, rings and other workpieces whose thickness is within the effective range. Drilling through holes and blind holes can be realized on single material parts and composite materials. The machining process of the machine tool is digitally controlled and the operation is very convenient. It can realize automation, high precision, multiple varieties, and mass production.
