I. Overview of TC18 titanium alloy
TC18 titanium alloy is a high-strength + duplex titanium alloy with excellent mechanical properties and corrosion resistance, which is widely used in aerospace, chemical, medical and other fields. The selection of its machining process has a crucial impact on the performance of the final product.
Material selection: ensure the selection of high-quality TC18 titanium alloy raw materials to ensure the quality of the processed product.
Pre-treatment: carry out the necessary pre-treatment of raw materials, such as cleaning, degreasing, etc., in order to remove surface impurities and oil, and improve processing efficiency and quality.
Cutting: Use suitable cutting tools (such as laser cutting machine, waterjet, etc.) to cut the TC18 titanium alloy raw material into the required shape and size.
Forming: The cut material is processed into the required shape and size by forging, rolling, extruding and other forming processes.TC18 titanium alloy large-size rods are usually forged by a multi-fire forging process with "high - low - high" temperature characteristics, in order to obtain a uniform organization and excellent performance.
Turning: TC18 titanium alloy is turned using a lathe to obtain precise dimensions and shapes.
Drilling: Drilling of holes in TC18 titanium alloy using a drill press or drilling machine to meet specific design requirements.
Selection of suitable tools: Due to the high hardness of TC18 titanium alloy, machining requires the use of high-speed tungsten steel or multi-layer coated carbide tools, and optimization of tool geometry to improve machining efficiency and quality.
After processing, we need to carry out strict quality inspection of TC18 titanium alloy products, including dimensional accuracy, surface quality, mechanical properties and other aspects of the test to ensure that the product meets the design requirements and use standards.
The processing of TC18 titanium alloy is a complex process involving multiple links and technologies, which requires strict control of the process parameters and quality requirements of each link to ensure the performance and quality of the final product.
