Car milling composite parts refer to mechanical components manufactured through car milling composite processing technology. Turning milling composite machining is the integration of turning and milling into one device, which completes most or all of the machining processes of the parts in one clamping, thereby reducing the number of clamping times, improving machining accuracy and efficiency. The following is an explanation based on multiple characteristics combined with professional data:
1. High precision
In the combined machining of turning and milling, the parts are processed in multiple processes under one clamping, avoiding positioning errors caused by repeated clamping. For example, in the processing of aircraft engine turbine discs, the roundness error of the parts can be controlled within 0.003mm and the surface roughness can reach Ra0.8 μ m through a combination of turning and milling equipment. Compared to traditional step-by-step processing, its dimensional consistency has been improved by more than 50%, providing reliable guarantees for the manufacturing of high-precision components, especially suitable for Industries with extremely strict requirements for dimensional accuracy and form and position tolerances, such as aerospace, precision instruments, etc.
2. High efficiency
Due to the reduction of clamping, tool changing, and transportation time between processes, the efficiency of turning milling composite machining has been significantly improved. Taking the machining of automobile engine crankshafts as an example, traditional machining processes require multiple equipment and clamping, and it takes 6-8 hours to process one crankshaft; By adopting the combination of turning and milling processing technology, the processing time can be shortened to 3-4 hours, and the production efficiency can be increased by about 50%. At the same time, the milling and turning composite equipment is equipped with a fast tool changing system, and the tool changing time can be controlled within 1-2 seconds, further improving the processing continuity, which is particularly advantageous in large-scale production.
3. Ability to process complex shapes
The combination of turning and milling composite machining combines the rotational machining of turning and the multi axis linkage machining capability of milling, which can easily achieve the machining of complex shaped parts. For parts with complex surfaces, irregular holes, thin-walled structures, and other features, such as Medical implants (such as artificial joints), the turning milling composite equipment can achieve high-precision machining of complex surfaces through five axis linkage machining, precise control of tool paths, and machining accuracy of up to ± 0.01mm, meeting the strict requirements for biocompatibility and functionality of parts in the Medical field.
4. Wide adaptability of Materials
Car milling composite processing can handle a variety of materials, from common steel and aluminum alloys to difficult to machine materials such as titanium alloys and high-temperature alloys. Taking the processing of titanium alloy aviation structural components as an example, the turning milling composite equipment adopts high-speed cutting technology, with a spindle speed of 10000-20000r/min and a feed rate of 500-1000mm/min. By optimizing cutting parameters, cutting force and cutting temperature can be effectively controlled, tool wear can be reduced, surface quality can be improved, and efficient and high-quality processing of titanium alloy materials can be achieved.
Application scenarios of car milling composite parts
1. Aerospace field
The aerospace industry has extremely high requirements for precision, strength, and lightweight components. Car milling composite parts are widely used in the manufacturing of key components such as engine blades, casings, and turbine discs. For example, the machining of engine blades requires precise control of their profile and airflow channels. Turning milling composite machining can achieve high-precision machining of complex curved surfaces of blades while ensuring the strength and fatigue performance of materials. In the research and development of new aviation engines, the combination of turning and milling technology can shorten the manufacturing cycle of components by 30% -50%, and improve the overall performance and reliability of the engine.
2. Automotive manufacturing industry
The automotive manufacturing industry has strict requirements for the processing efficiency and quality of components. Car milling composite parts play an important role in the manufacturing of automotive engines, transmissions, chassis, and other components. Parts such as camshafts and crankshafts in automotive engines can be produced with high precision and efficiency through milling and turning composite machining, reducing production costs. At the same time, for new components such as motor shafts and battery housings in new energy vehicles, milling and turning composite processing can also meet their special shape and precision requirements, helping the automotive industry to transform and upgrade.
3. Medical device industry
Medical devices have strict requirements for the accuracy, hygiene, and biocompatibility of their components. The car milling composite processing technology can be used to manufacture high-precision medical devices such as artificial joints, dental implants, surgical instruments, etc. For example, the ball head and socket body of artificial joints require extremely high dimensional accuracy and surface quality. The turning milling composite equipment can achieve micrometer level machining accuracy, ensuring the flexibility and service life of the joint, and providing strong protection for the health of patients.
4. Energy sector
In the field of energy, such as wind power generation, nuclear power generation, etc., milling and turning composite parts are also widely used. The key components of wind turbines, such as gearboxes and main shafts, need to have high strength, high precision, and good fatigue performance. Car milling composite machining can achieve efficient and high-quality manufacturing of these large and complex parts, improving the reliability and power generation efficiency of wind power equipment. In nuclear power generation, for some small and precise nuclear equipment components, milling and turning composite processing can also meet their strict processing requirements, ensuring nuclear energy safety.
