In the process technology of high precision parts processing, turning has always been difficult. Under the action of cutting force, gravity and top pressing force, the slender shaft placed horizontally is easy to bend or even lose stability. Therefore, the stress problem of the slender shaft must be improved when turning the slender shaft. The slender shaft placed horizontally is easy to bend or even lose stability;

To improve the machining accuracy of slender shaft is to control the stress and thermal deformation of the process system. Therefore, a series of effective measures such as reverse turning, matching with suitable tools and geometric parameters, cutting parameters tensioning device and shaft sleeve type tool holder are adopted to improve the rigidity of slender shaft, obtain good geometric accuracy and ideal surface roughness, and ensure the machining requirements.

All shaft high-precision parts processing in the geometry of the accuracy is relatively high, the main performance is: the accuracy of the geometric shape of the focus refers to the outer cone of the surface, cylindrical degree, shaft tight and the end of the taper hole.

In the processing and production of high precision shaft parts, the tolerance is normally limited to a certain range of dimensional tolerances. However, for the surface of the inner and outer circles with high precision requirements, we should mark the extraction tolerance on the designed drawings. The products we process will undergo strict quality inspection to ensure that the precision reaches the high standard of customers.
