High Efficiency Processing Scheme for Titanium Alloy
The technician engaged in the processing of titanium alloy is familiar with this special difficulty cutting material. This material has excellent stability at the same time. The weight is very light. Titanium alloy in the aviation industry is growing. Extensive use of titanium alloy and composite materials is the future development trend of large civilian airliners, military fighters and spacecraft. This technical tendency is not only reflected in the aircraft structural parts, but also in the engine parts.
As we all know, titanium alloy because of its high hardness and poor thermal conductivity of the reasons, the cutting tip need to withstand a high temperature. Moreover, titanium alloy parts of the hair are usually made of cold forging process, the hardness increased significantly, the tensile strength increased by three times the yield strength is the highest reduction of 90%. This makes the tool more easily cutting at cutting time.
Special tools designed for the user process can greatly improve the efficiency and accuracy of titanium processing now people can be based on the final application of parts to optimize the performance of the material. Ti-5553 alloy (Ti-5Al-5V-5Mo-3Cr) is a characteristic. Due to its light weight, high tensile strength and good corrosion resistance, Ti-5553 alloy is the ideal material for today's aviation industry. However, the advent of Ti-5553 alloy makes processing more difficult. Ti6Al4V is a classic α-β aerospace titanium alloy with a balanced crystal structure (α = hexagonal crystal structure, β = central cube crystal structure). Ti-5553 alloy is a titanium alloy closer to the β structure, with more β components. This structure makes the Ti-5553 alloy heat resistance higher, even if the cutting process to produce a lot of heat, but Ti-5553 alloy tensile strength is still 900N / mm2. Therefore, this material is more difficult to cut. The β component increases the effect of sticking a knife.
High efficiency, high precision machining of titanium alloy on the cutting process and equipment is a huge challenge. As early as the 1960s, customers around the world have already used Stalag's equipment and technology to process titanium parts on aircraft; for decades, the technical experts of the Stalag Hector have Alloys and similar difficult cutting materials processing has accumulated a wealth of experience. Thanks to the exceptional processing center and expertise in all aspects of processes, knives and coolants, Stalag Hector has become a leading supplier of titanium and similar hard-to-cutting materials processing centers.
Stark Grove Machining Center uses a finite element analysis of the welded steel structure process, tool and coolant. In order to attain high-precision and high efficiency machining, it is necessary to select the appropriate milling scheme. "Virtual Machining" has a clear advantage in this area. It can save programmers a lot of time, and to minimize the test on the machine.
RCS 7 programming software combined with virtual machining has shown great convenience in turbine blade processing. Virtual machining is also critical and practical in the programming of structural parts. Most of the weight of the workpiece are only one tenth of the original weight of the embryo, and the efficiency roughing strategy is as important as the high quality finishing strategy.
For difficult processing, the Stalag Hecott uses high rigidity special tools, which can dramatically improve the efficiency of turbine blades, integral discs and impellers. Scarborough Hector and the world's leading suppliers of cutting tools and coolants to provide customers with technology-leading solutions.
STC 1000 machining centres is roughing titanium alloy structure. High rigidity machine with good damping performance, high efficiency and high precision machining deep groove is very important strong machining center Stalag Hecott brings its experience of years of five-axis machining difficult cutting materials to STC series processing center of the design. This modern machining center meets the requirements of different clients in terms of process stability, workpiece surface quality, accuracy, reliability and user friendliness. STC series machining center is particularly suitable for demanding cutting materials, such as: Ti-5553 alloy five-axis linkage processing.
In order to satisfy the requirements of titanium processing, STC series of processing centers using high-rigidity, closed welding bed. The damping performance of this structure is similar to that of a cast bed, but its tensile strength is enhanced by 25%. With the self-locking function of the rotating shaft with superior shock absorption, high torsional strength of the worm gear drive, anti-interference ability, even under heavy load conditions can also perform five-axis linkage roughing. This ensures that the tool has a longer life when the titanium alloy is machined with extreme efficiency.
STC series of strong precision swing so that you can in a clamping under the workpiece for the overall processing, reduce unnecessary tooling equipment and shorten the preparation time. The distance from the compact swing head to the end of the spindle is very short, thus reducing the follow-up movement of the other axes of the a-axis during high-precision operation.
In addition, the swing head structure makes the short tool easy to reach the workpiece, and the cutting force in the rotating shaft and the bed of the torque are small. This is a necessary condition for high efficiency and high-precision machining of titanium alloy parts.
Single axis of the BTP-5000 linear axis X / Y / Z of the trip were 5000 (6000) / 2000 / 1200mm, weighing more than 200tSTC series of processing centers in particular to consider the thermal factors of the machine. The thermal expansion coefficient of the machining center is minimized by means of symmetrical bed design, thermostatic coolant, intelligent control of the spindle and continuous cooling of components. The workpiece can maintain the required accuracy even after 100 hours of continuous machining.
BTP-5000 is designed for large structural parts
States Hecott designed BTP-5000 large titanium processing center for aircraft large titanium alloy components, which is also an extension of the successful STC series of machining centers. This large machining center also has the advantages of high-rigidity and high precision. The BTP machining center is dedicated to the overall machining of titanium alloy structures or similar hard-to-cut materials and can be efficiently machined with five-axis linkage.
The structure of the BTP-5000 guarantees that the machining center has extremely high dynamic and static rigidity. BTP-5000 core components are high-rigidity, high precision swing head. The swing head based on STC series swing head advance, the maximum torque of 1000Nm, the maximum spindle speed 8000rpm, to meet a variety of application requirements. The BTP-5000 can be set in a variety of automated machining options such as workpiece and tool measurement, tool identification coding, and status monitoring systems. Self-developed graphical diagnostic system SAM makes the product more perfect.
