Stability is the key to success. Some machining workshops find it difficult to process titanium effectively, but this view does not represent the development trend of modern processing methods and cutting tools. Some of the reasons for the difficulty are that titanium metal processing is attributed to new technology and has little learning experience. In addition, difficulties are usually associated with expectations and the experience of operators, especially those who are now accustomed to the processing of materials such as cast iron or low alloy steel, which usually require very low processing requirements. In contrast, the same cutting tool and the same speed can not be used to process titanium metal, and the number of tool life is different, even compared with some stainless steel, titanium metal processing is still much more difficult. It is necessary to adopt different cutting speed and feed rate as well as certain preventive measures to process titanium metal. Compared with most data, titanium is also a kind of material that can be processed directly. As long as the titanium workpiece is stable, the clamping is firm, the machine tool is selected accurately, the power is suitable, the working condition is outstanding, and the BT50 spindle with short tool overhang is equipped, all doubts will be solved conveniently. However, in practical milling, the conditions required for titanium metal processing are not simple and satisfactory, because they do not always have ideal stability conditions. In addition, many titanium parts are in a messy shape, perhaps including many thin or far-reaching cavity, thin wall, bevel and thin bracket. If we want to successfully process such parts, we need to use them.

Various characteristics of titanium make it an attractive part material, but many of them also affect its machinability. Titanium has excellent strength-component ratio, and its density is usually only 60% of that of steel. The elastic coefficient of titanium is lower than that of steel, so its texture is harder, its flexibility is better, and its corrosion resistance is better than that of stainless steel. These characteristics mean that titanium metal will produce higher and more concentrated cutting force in the process of processing. It simply vibrates and causes tremor in cutting; it also simply responds to the data of cutting tools, and then aggravates the wear of crescent holes. In addition, its thermal conductivity is poor. Because the heat mainly gathers in the cutting area, it is necessary for the cutting tool to have high thermal hardness.
