Magnesium alloys have become the representative of a new generation of lightweight materials due to their low density, high specific strength, and excellent shock absorption performance. The integration of CNC processing technology provides key support for the precision manufacturing of magnesium alloy parts, enabling the mass production of magnesium alloy parts with complex structures and high precision requirements. From aircraft frames at an altitude of 10,000 meters to the chassis of new energy vehicles on urban roads, CNC magnesium alloy parts processing technology is reshaping the landscape of modern manufacturing and promoting various industries to move towards higher performance and greener environmental protection.
Magnesium alloy parts processing
CNC magnesium alloy parts processing refers to the technology of using computer digital control systems to perform automated, high-precision cutting processing on magnesium alloy materials. This technology converts part design drawings into CNC instructions through programming software, controls the tool motion trajectory and cutting parameters of CNC machine tools (such as machining centers, lathes, milling machines, etc.), realizes milling, turning, drilling, grinding and other processing operations on magnesium alloy materials, and finally manufactures high-precision parts that meet design requirements.
Types of magnesium alloy parts processing
Structural parts processing
Mainly used to manufacture frame structures, brackets, shells and other parts in the fields of aerospace, automobiles, etc., such as aircraft fuselage frames, automobile chassis brackets, laptop computer shells, etc. Such parts usually have complex curved surface structures and high strength requirements, and need to be processed with high precision through multi-axis linkage CNC machining centers.
Functional parts processing
For magnesium alloy parts with specific functions, such as engine cylinders, transmission housings, heat dissipation components, etc. In addition to requiring high-precision dimensions and shapes, such parts must also meet functional requirements such as good heat dissipation performance and sealing. Special processing techniques (such as EDM and laser processing) are required for auxiliary processing during the processing process.
Precision parts processing
Precision components used in the fields of electronics and medical care, such as mobile phone camera brackets, medical device shells, precision instrument parts, etc. Such parts are small in size and high in precision (tolerance requirements of ±0.005mm), and need to be processed with high-precision CNC equipment and micro-diameter tools, and the temperature, humidity and cleanliness of the processing environment must be strictly controlled.
Precautions for machining magnesium alloy parts
Cutting parameter control
Magnesium alloy has low hardness and good cutting performance, but high thermal conductivity and low melting point. It is easy to produce problems such as sticking and built-up edge during machining. Avoid excessive cutting temperature, which may cause deformation of parts or increased tool wear.
Tool selection
Tools with good wear resistance and high sharpness should be selected, such as carbide tools and coated tools. The front angle and back angle of the tool need to be optimized according to the machining process to reduce cutting force and cutting heat and improve the machining surface quality.
Chip treatment
Magnesium alloy chips are flammable. During the machining process, a special chip removal device should be used to clean the chips in time, and compressed air should be avoided to blow the chips to prevent the chips from flying and causing fire. Cutting fluid or oil mist cooling and lubrication can be used to reduce the cutting temperature and help the chips to be discharged.
Anti-oxidation and anti-corrosion
Magnesium alloys are chemically active and easy to oxidize and corrode. Protective measures should be taken during the machining process, such as keeping the machining environment dry and avoiding contact with water, acid, alkali and other substances; surface treatment should be performed in time after machining to prevent oxidation, discoloration or corrosion of parts.
Optimization of clamping method
Since magnesium alloy parts have poor rigidity, it is necessary to select appropriate clamps and clamping methods when clamping to avoid deformation of parts due to excessive clamping force. Vacuum adsorption clamps, elastic clamps, etc. can be used to ensure accurate positioning and reliable clamping of parts during processing.
Application fields of magnesium alloy parts processing
Aerospace field
CNC magnesium alloy parts are widely used in aircraft fuselage structures, engine components, avionics equipment, etc. For example, aircraft seat frames, wing brackets and other parts made of magnesium alloy can effectively reduce the weight of the aircraft, improve fuel efficiency and flight performance; magnesium alloy engine covers help reduce engine vibration and noise.
Plays a key role in the process of lightweighting automobiles and is used to manufacture automobile chassis parts (such as subframes, control arms), engine blocks, transmission housings, etc. The use of magnesium alloy parts can reduce the weight of automobiles by 10% - 20%, significantly improve fuel economy and handling performance, and reduce exhaust emissions, which is in line with the development trend of new energy vehicles.
Consumer electronic products
Such as the shells, internal brackets and other parts of electronic products such as mobile phones, laptops, and tablets. The lightweight, high strength and good electromagnetic shielding properties of magnesium alloys make electronic products thinner and stronger, while meeting electromagnetic compatibility requirements and improving user experience.
Medical devices
Used to manufacture surgical instruments, medical equipment shells, etc. The biocompatibility and lightweight properties of magnesium alloys help reduce the weight of medical devices, improve operational convenience, and reduce patient discomfort during use.
Sporting goods
In sports equipment such as bicycles, golf clubs, and skis, CNC magnesium alloy parts are favored by professional athletes and sports enthusiasts for their light weight, high strength, and good shock absorption properties, which improve the performance and user experience of sports equipment.
