What is the Bad Phenomenon Caused by Improper CNC Spinning Machine Process?

As a CNC Spinning Machine Manufacturer, share with you.

At present, China's CNC Spinning Machine process parameters are still selected by experience. On the one hand, it has caused problems such as long design cycles, high trial production costs, and difficult manual programming of NC; on the other hand, it also affects the final forming quality of the spin-machined products. In actual production, there are many factors that affect the quality of spinning products, including process device factors, blank factors and process parameter factors.

Before the spinning process, make all preparations, which will help us to complete the entire metal processing process smoothly. Only by making sufficient preparations before the processing technology can future processing work be completed more smoothly. So what preparations should we do?

On the one hand, before the work of spinning processing, we must determine the model of the entire part and confirm the overall design thinking of the processing, which is of great significance for us to do a good job of each process.

On the other hand, we must make a reasonable plan before the entire spinning process begins. This plan includes time and the application of raw materials, which will help us to carry out the following work more smoothly.

Spinning production practice shows that the blank does not meet the process requirements, improper selection of spinning process parameters, irrational design of spinning tools and substandard machining accuracy, etc., often cause the following undesirable phenomena during spinning: The material has fractures, microcracks and internal cracks. The surface bulges or bulges. The inner and outer surfaces are burred. The tail section forms flares or wing cracks. It is not too straight, does not stick to the core mold, the surface peels, and stagnates the front metal. Pile up, ripples on the surface, etc.

Spinning processing Under heating conditions, strong spinning processing will increase the process factors and complicate the process, so cold spinning is generally used for metals with better plasticity, but for refractory metals with poor plasticity, it must be hot Spinning.

The heating temperature of the material during the strong spinning process is slightly the same as that used in ordinary stamping. If the temperature is too high, recrystallization will occur, and recrystallization will make the grains coarse, and the fiber structure of the material will also be coarsened. The multi-pass spinning process will have a very adverse effect. At this time, if you want to successfully complete the multi-pass spinning process, you must perform the corresponding heat treatment, which will greatly increase the cost of the metal spinning processing plant.
