TIP of titanium and titanium alloys

TIP of titanium and titanium alloys
Titanium is a refractory metal of a light metal, a density of 4.5 g / cm3, 57% only of iron. Strength titanium plate alloy with high strength comparable to steel, but also has good heat resistance and low temperature performance, long-term work at certain alloy between 450 ℃ ~ 550 ℃ and minus 250 ℃.
Circular blade cutter suitable for milling titanium, because they may be appropriate to change the main angle. As long as these cutters equipped with special blades and apply the correct cutting parameters, under normal circumstances can improve the stability and overall performance. Feed per tooth should be set to the minimum amount, which is crucial.
Titanium and titanium - titanium milling need the right conditions compared with most other metal materials processing, titanium bolts processing requires not only higher, but more limited. This is because the alloy has metallurgical characteristics and material properties and cutting action may have a serious impact on the material itself. However, if you select the appropriate tools and use them correctly and in accordance with the requirements of the titanium processing tools and configuration optimization to the best condition, then fully meet these requirements, and obtain satisfactory performance and perfect results. Many of the problems of traditional titanium metal processing encountered is not inevitable, as long as the properties of titanium to overcome the effects of the process, we can succeed.
Various properties of titanium parts and materials to become a powerful attraction, but many of the properties but also affect its workability. titanium bar stockhas excellent strength - weight ratio, which is usually only 60% of the density of steel. Titanium elastic coefficient lower than steel, so the texture is harder, better deflection. Erosion-resistant stainless steel is better than titanium, and low thermal conductivity. These properties mean that titanium metal in the process will produce higher and higher concentration of cutting force. It is prone to vibrations caused by the tremor occurred while cutting; and, it is easy to react with cutting tool materials in cutting Shihai, thus exacerbating the crater wear. In addition, its thermal conductivity is poor, mainly because of the heat in the cutting area, so the processing of titanium metal tool must have a high thermal hardness.
