Titanium has been chosen as the ideal human implant product due to its good biocompatibility. For more than a decade, many scientific research departments, medical schools and hospitals in many countries all over the world have done a lot of basic work and clinical research. They have admitted that titanium is the best human implant product in depth and breadth. In these years, titanium There have been thousands of records of artificial femoral head, artificial wrist joint, knee joint, artificial tooth, cranial repair, pacemaker and so on. The research, stare and contrast of these years have been reported so far in titanium The ideal product for human implants. Orthopedic devices are designed to conform to the complex shape of bones and joints, and the machining of these parts is complicated. These devices, machined from titanium rods, require a large amount of material to be cut off, making the process expensive because of the low cutting performance index of many materials. So, some parts are cast close to the final shape of the part, which often requires complex and expensive fixtures.

Titanium 6AL-4V ELI is a canonical product for the manufacture of hip joints, bone screws, knees, plate-shaped bones or organs, dentures and surgical equipment.

However, cobalt-chromium alloys are used more and more frequently because of their robustness, tighter grain size and cleaner than titanium. However, the metallurgical nature of titanium alloys makes them harder to machine than steels with the proper hardness. Titanium has a hardenability, a feature that eliminates the consolidation of metal (curling) on the front of the cutting tool. This helps increase the cutting angle during machining, thus forming a thin chip that touches the outer surface of the cutting tool over a suitably small area. Because of this work hardening, in the tool and workpiece movement touch, the feed should not stop. In this way, the large supporting forces that occur during machining, combined with the frictional forces generated by the chips in the touch area, result in a significant increase of heat in the tool section. Cutting heat generated by titanium, will not be quickly dissipated, because it is poor conductor. Therefore, most of the heat is concentrated on the cutting edge and tooling. Large bearing capacity and heat, forming crescent depression near the cutting edge, resulting in rapid damage to the tool. Even worse, there is a strong tendency for titanium alloys to alloy or rejuvenate chemically with product melts at tool operating temperatures, and there is also a tendency that when the chips stick to the cutting edge of the tool, the appearance of the tool damage. These difficulties are doubled when the tool starts to break down. Therefore, tools used to machine titanium and its alloys should be carefully monitored to ensure sharp edges and to be replaced before grinding. The experience with titanium and titanium alloys is that if any change is seen during machining, the tool should be changed immediately because the change means that the tool should be dull. Another reason to insist on sharp knives is that titanium can cause fire when cut with damaged or damaged knives. When burning, the metal produces oxygen, so the fire spontaneously ignites. Therefore, many titanium processing workshop not reported fire, they are equipped with a rescue system on the machine.

Titanium has a moderately low modulus of elasticity and a higher elasticity than steel, and therefore tends to run counter to cutting tools during machining unless robust cutting or proper support is required. Slender parts in the tool pressure, tend to deflect, resulting in chatter, knife friction and work-poor problem. Through the processing experience that the rigidity of the entire tool system is very important to use sharp, accurate shape of the tool. As a result of these pressures, new technologies are introduced to help manufacturers of medical parts respond to competition. Processibility To produce these complex parts with very high accuracy; many of the innovations in EDM make high quality parts faster and eliminate many older processes The inherent problem.

As a new product, medical titanium is used in the development of China's pharmaceutical industry, medical devices, human implants, etc., for nearly two decades. However, it achieved great success and achieved significant social and economic benefits, shortening the gap between China and the advanced countries in the world.

Titanium advantage

1. Titanium is a green product, titanium reduction fast wear and tear regeneration of 50 years will not rust, Hagrien drawn The raw materials used are from China Baoji (China titanium Valley)

2. Hardness, Titanium alloy than the strength (strength  density) is much larger than other metal structures, titanium is very strong, can withstand high pressure.

3. Good heat resistance the new titanium alloy can be long-term use at 600 ℃ or higher temperature.

4. Corrosion resistance is a very lively metal, the titanium surface to generate a dense, strong adhesion of the oxide film to protect the titanium substrate is not corroded. Even self-healing or regenerating quickly due to mechanical wear.

5. Physical Features Titanium has a metallic luster, ductility. Pure titanium, plastic greater. Has good corrosion resistance, will not be affected by the atmosphere and sea water will not rust for 50 years.

6. Heat transfer performance is good although the thermal conductivity of titanium than carbon steel and copper, titanium surface scaling can also reduce the thermal resistance, the titanium heat transfer performance significantly improved.

7. Non-magnetic, non-toxic Titanium is a non-magnetic metal, non-toxic and has good compatibility with human tissues and blood, it is used by the medical profession.

8. Uses electronics, chemicals, watches, glasses, jewelry, sporting goods, machinery and equipment, electroplating equipment, environmental protection equipment, golf balls and precision machining and other industries.

9. Titanium wire Uses military, medical, sporting goods, glasses, earrings, headdresses, electroplating rack, wire and other industries.

10. Titanium rod purposes mainly for mechanical equipment, electroplating equipment, medical, all kinds of precision machinery and other industries.
