Belongs to the high precision CNC machining center equipment, machining accuracy is extremely important, so its artifacts can meet the processing requirements would depend on the accuracy of numerical control machining center itself, and in determining the quality of CNC machining center is its main shaft. CNC machining center spindle is the rotary motion and torque through the shaft end of fixture is passed to the workpiece and cutting tool, requires a very high strength and rotation accuracy, its structure is ladder hollow shaft, cylindrical surface with spline function such as, the key slot and thread. Therefore, the production of the main shaft of the process and processing methods, the entire CNC machining center processing has a very important role.

The processing technology of the nc machining center spindle route roughly, you first need to drawing analysis, determine the cutting surface, and then to analyze the surface roughness, machining precision of each processing surface is determined, to determine the machining method. Finally, according to the processing parts of the blank, heat treatment requirements, batch production size and processing conditions to properly arrange other processing procedures.

Spindle is the core component of numerical control machining center, its machining quality directly affects the effectiveness and efficiency of the numerical control processing center, therefore in the process of machining need according to the working conditions and technology requirements of CNC machining centers, formulate rational and effective processing technology and heat treatment. Nc rapid development in recent years, in the process of nc machining center spindle can with the aid of numerical control processing equipment, such as using CNC production can effectively improve production efficiency and precision parts processing, in the aspect of mechanical equipment can be homemade tightening sleeve and the taper sleeve and so on, to further satisfy the processing requirements.
