Characteristics of titanium and titanium alloys
Titanium is a silvery white metal, it has many excellent performance. The density of titanium was 4.54g / cm3, 43% lighter than steel, lighter than the prestigious magnesium slightly heavier. Mechanical strength of steel but with similar, more than twice as large as aluminum, magnesium than five times. Titanium, high temperature, the melting point of 1942K, higher than that of gold near 1000K, higher than that of steel nearly 500K.
Chemical properties of titanium alloy sheet are relatively active metal. Can be non-metallic effect with O2, N2, H2, S, and halogen when heated. However, at room temperature, dense titanium oxide surface protection film is easy to generate a very thin layer, can resist strong acid or aqua regia role, showing strong corrosion resistance. Thus, the general metal becomes riddled with acid, alkali, salt solution, and titanium are safe and sound.
Dissolve almost all of the liquid titanium metal, and a variety of metals can be formed alloy. Join prepared titanium steel titanium steel tough and elastic. Titanium metal Al, Sb, Be, Cr, Fe, etc. generated between interstitial compound or metal compound.
The same aircraft titanium bar for sale alloy aircraft heavier than other metals contained more than 100 passengers. Made submarines, both seawater corrosion resistance, but also anti-deep pressure, the dive depth increased by 80% compared to stainless steel submarine. Meanwhile, titanium rod for sale non-magnetic, not mine found, with good anti-guardianship role.
Vanadium has a "pro-biotic" 'sex. In the human body, can resist corrosion and non-toxic secretions, adapt to any sterilization methods. It is widely used in making medical devices, making artificial hip, knee, shoulder, threatening joints, skull, active heart valves, bone clip. When a new package in these muscles annulus "titanium-bone", these titanium bone began to maintain the body's normal activities.
Titanium is widely distributed in the body, in an amount of normal body weight not more than 70kg per 15mg, its role is unclear. But titanium can stimulate phagocytic cells, so that the immune system has been proven to enhance this effect.

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 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 material 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 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 medical titanium alloy 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 has 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.
Stability is the key to success lies
Some machine shops find it difficult effective titanium processing, but this view does not represent the development trend of modern processing methods and tools. The difficulty, in part because of the titanium metal processing is an emerging technology, the lack of useful experience. In addition, the difficulties often associated with the operator's experience and expectations related, especially some people have become accustomed to cast iron or low-alloy steel and other materials, processing methods, the processing requirements of these materials is generally low. In contrast, it seems that titanium metal processing is more difficult, because they can not use the same tool during machining and at the same rate, and the tool life is also different. Even compared with some stainless steel, titanium metal processing difficulty also still high. While we can say that the processing of titanium must take different speeds and feed rates and certain precautions. In fact, most of the material compared with the material, titanium is also a fully machined directly. As long as titanium workpieces stable clamping firm, choosing the right tools, the right motivation, good working conditions, and is equipped with a shorter tool overhang of ISO 50 spindle, all problems will be solved - as long as the cutting tool correctly.
However, in actual milling, titanium required for processing is not easy to satisfy all of the conditions, because the ideal conditions do not always have stabilized. In addition, the shape of many parts of titanium alloy wire complex and may contain many fine or deep cavity, thin-walled, bevel and thin bracket. To be successful processing of these parts, you need to use a large overhang, small diameter tools, which will affect the stability of the tool. In the processing of titanium metal, are often easier to potential stability problems.
Must consider the vibration and heat
Non-ideal environment also includes other factors, one of which is that the majority of the current machine is IS0 40 spindle assembly. If the use of high-strength machines, can not long maintain a new knife state. In addition, if the part structure is more complex, usually difficult to effectively clamped. Of course, the challenge does not stop there, the cutting process is sometimes necessary for full slot milling, side cut or contour milling, all of which are likely (but not necessarily) the formation of vibration and poor cutting conditions. Importantly, when setting the machine, you must always pay attention to improve the stability of the trend in order to avoid vibration. Vibration can cause chipping blade, blade damage and produce the results unpredictable and inconsistent. An improved measure is to adopt a multi-stage clamping the part closer to the spindle to help offset the vibration.
Since titanium metal at a high temperature can maintain its hardness and strength, and thus the cutting edge will experience high forces and stresses, together with heat generated in the cutting zone, means that the work hardening is likely to occur, which causes some problems generating, particularly those affecting the subsequent cutting step. Therefore, choose the best indexable insert grades and geometries are critical to the success of the process. Past history has proven, fine-grained non-coated insert grades are very suitable for titanium metal processing; now insert grades have more PVD titanium coating can greatly improve performance.
