Shaft parts processing technology

1. Basic principles of processing technology formulation
The position near the tool point is first produced and processed, and the position far from the tool point is later produced and processed; First arrange rough machining of inner and outer surface, and then finish machining of inner and outer surface; Make the process simple and clear, reduce the probability of error and improve the efficiency of programming.
2. Process division
To a installation, production and processing as a process: suitable for the production and processing of less parts; With the same tool production and processing content division process; Dividing the process by the production and processing position is suitable for the production and processing of many parts.
3. Clamping method
The universal fixture of CNC lathe is chuck, generally three jaw chuck. Selection of three jaw chuck production and processing shaft parts, parts axis to coincide with the middle line of the chuck, usually do not need to find the right, clamping speed is faster.
For parts with higher precision requirements, the following production and processing methods are commonly used:
Two - tip clamping: for longer or must be through several clamping can be produced and processed. Such as long shaft, screw, etc. Convenient clamping, no need for alignment, high clamping accuracy. But the center hole must be drilled in the end face of the workpiece before clamping.
One top and one clip installation: Although the workpiece is loaded with two top clips, the accuracy is high, but the rigidity is poor, which affects the improvement of the cutting dosage. Turning usually shaft parts, especially the heavier workpiece, can not be clamped with two tips, and with one end of the clamp, the other end with the back tip of the clamping method.

In the processing of shaft parts, people often carry out grinding after turning processing, and use circular grinding to improve the accuracy of shaft parts. However, sometimes it is encountered that no matter how good the precision of circular grinding is, the precision of processed shaft parts still cannot be improved.
At this time should think about whether other links out of the problem!
In the cylindrical grinding of shaft parts, there is a very small key point is often ignored by people, that is, the guarantee of the accuracy of the center hole of shaft parts.
The central hole of shaft parts is not only the design benchmark of the parts, but also the processing benchmark and the inspection basis of the qualified parts. Thus, the importance of the center hole of the parts! That is to say, the Angle, circle and roughness of the center hole of the parts should reach a certain accuracy, otherwise the best cylindrical grinding machine can not grind the cylindrical dimension accuracy and shape position accuracy of the parts.
So how can you make a high precision center hole?
The answer is: use the center hole grinder to precision grinding of the two ends of the shaft parts.
