Mobile phone LCD aluminum frame precision processing process
The precision processing of mobile phone LCD aluminum frame is a very key part of the manufacturing process, which is directly related to the quality, appearance and performance of the final product. The following is a detailed introduction to the precision processing process of mobile phone LCD aluminum frame:
Precision machining process
1. Design and programming
CAD design: First, it is necessary to accurately draw the design drawings of the aluminum frame through computer-aided design (CAD) software. This step ensures that the size and shape of the aluminum frame meet the design requirements.
CAM programming: Next, computer-aided manufacturing (CAM) software is used to translate CAD designs into machining instructions that CNC machines can understand.
2. Material selection and preparation
Material selection: Aluminum alloy is usually selected as a raw material, such as 6063 or 6061 models, which have good mechanical properties and easy processing characteristics.
Plate cutting: According to the design specifications, the use of laser cutting machine or water knife and other high-precision equipment for the preliminary cutting of aluminum alloy plate, forming a blank close to the shape of the finished product.
3. CNC precision machining
Milling: A CNC milling machine is used to remove excess material and precisely define the shape and internal structure of the aluminum frame. This process requires multiple adjustments to the workpiece position to achieve complex three-dimensional shapes.
Drill holes: Drill holes in the specified position for subsequent installation of screws or other fasteners. Ensure the accuracy and consistency of the hole positions when drilling.
Turning: If you need to make cylindrical or other rotationally symmetrical parts, you can use a CNC lathe for machining.
4. Surface treatment
Deburring and polishing: The burrs produced during processing are removed and the surface is polished by hand or mechanically to make it smooth and flawless.
Anodizing: In order to enhance corrosion resistance and allow dyeing, an oxide film is usually generated on the surface of the aluminum frame. This process can also increase surface hardness.
Other treatments: According to specific needs, further surface treatments such as sandblasting and electroplating can also be carried out to improve the appearance or give specific functional characteristics.
5. Quality control
Dimensional inspection: Use high-precision measuring tools such as a coordinate measuring instrument (CMM) to check that key dimensions meet design requirements.
Appearance inspection: manual or automated equipment to detect surface defects, scratches and other defects.
Physical performance testing: including hardness testing, tensile strength testing, etc., to ensure that the product meets the established mechanical performance standards.
6. Assembly preparation and delivery
Preassembly: Add the necessary accessories or components, such as screw holes, interfaces, etc., for subsequent assembly with other parts.
Cleaning and packaging: Clean the aluminum frame thoroughly to ensure that it is free of dust and oil, and use anti-static packaging materials to protect it from damage during transportation.
Matters needing attention
Precision requirements: Since the mobile phone LCD aluminum frame requires a high degree of precision, tolerances must be strictly controlled throughout the processing process, especially in the CNC processing stage, and any small error may lead to assembly problems.
Choice of surface treatment: Different surface treatment methods not only affect the appearance of the aluminum frame, but also affect its durability and functional characteristics, such as electrical conductivity, heat dissipation, etc.
