What are machining parts? machining parts are extremely high tolerance requirement metal parts, reflected in tight tolerances, for example, tolerance requirement ISO 2768 -1 precision grade (f), special dimension requirement ± 0.01mm, the parts must strictly control the dimension tolerances and shape during design and manufacturing, the parts meet the specific functionality and reliability requirement. manufacturing machining parts involves multiple links, including material selection, design drawings, numerical control programming, CNC machining processing, surface treatment, and parts inspection. machining parts are often used in high-precision equipment and systems, such as electronics parts, mechanical equipment, medical equipment, high-end watchmaking, and the automotive industry.
How To Select Machining Parts Material
Material selection is critical to manufacturing machining parts, because it directly affects part performance, durability, processing costs, and final product quality. correct material selection ensures the part performs as expected in a specific operating environment, and meets design and functional requirements.
First of all, when selecting materials, consider material mechanical properties are the key factors. different materials have different strengths, hardness, toughness, and elastic modulus. these performance indicators determine the parts’ subjected force response and long-term stability. for example, high strength materials are better suited to withstand high loads, high toughness materials are better absorb shocks without breaking.
Secondly, the material thermal properties, such as thermal expansion coefficient, thermal conductivity, and heat resistance, it is crucial for machining parts application in high temperature environments. The material’s thermal expansion coefficient should match the working environment to avoid dimensional instability caused by temperature changes.
Furthermore, chemical stability and corrosion resistance are factors that need to be considered when selecting materials. when the parts are used in certain chemical or marine environments, the material needs to have good corrosion resistance to prevent performance degradation and structural failure.
In addition, the material processing properties are also important. some materials are easy to process, such as aluminum alloys and stainless steel. while other materials, such as titanium alloys, may be difficult and expensive. when selecting materials, you need to balance the material processing difficulty and cost, it will impact the part’s accuracy and surface quality during the processing.
Finally, material selection needs to consider environmental factors and sustainability. With the emphasis on environmental protection and sustainable development, select friendly environmentally and recyclable materials have received increasing attention. our material conforms to the EU carbon tariff CBAM standard.
Material selection is a multi-faceted process, a comprehensive evaluation based on the parts’ application scenario, performance requirements, cost budget, and processing conditions determines the most suitable material. through accurate material selection, we can ensure machining parts’ performance and reliability during design, processing, and application.
