M3 Aluminum Alloy CNC Hardware Parts Square Positioning Block Precision

Product Specification

M3 aluminum alloy precision CNC machined square positioning block

I. Core Considerations for Machining Before processing

1,Select suitable grades: 6061/6063 (general-purpose), 7075-T6 (high-strength), 5052 (precision micro);
2,Remove stress from the raw material (natural / artificial aging, annealing) to prevent deformation during processing;
3,Uniformly leave machining allowance, use soft pads for symmetrical clamping to prevent clamping damage / deformation.

II.During processing

1,Select hard alloy / diamond-coated tools, increase the rake angle to prevent tool adhesion;
2,Match cutting parameters: high speed and high feed for 6 series / 5 series aluminum, low speed and low feed for 7 series aluminum, reduce feed for edge processing to prevent chipping;
3,Use high-pressure coolant / cold air cooling, timely chip removal to avoid thermal deformation / surface scratches;
4,Follow the principle of "coarse first, then fine, surface first, then edge", use climb milling for finish machining, and leave 0.1-0.3mm finish allowance;
5,Real-time inspection: use calipers / dial indicators for rough machining, and use micrometers / CMM for finish machining to control flatness and perpendicularity.

III.After processing

1,Manual / ultrasonic deburring to ensure assembly fit;
2,Common surface treatments for aluminum alloys: choose as needed to enhance performance and fit
     Anodizing (natural / colored / black): general protection, improve corrosion resistance, suitable for 3C, general machinery, and building accessories;
    Hard anodizing: thickened oxide film, high wear resistance, scratch resistance, suitable for fixtures, moving parts, and industrial equipment parts;
    Electrophoretic coating: good insulation, smooth surface, suitable for electrical equipment and smart home brackets;
    Spray painting / powder coating: rich colors, impact resistance, suitable for building materials and appearance parts;
    Passivation / sealing: seal the pores of the oxide film, improve sealing and corrosion resistance, suitable for hydraulic / pneumatic system parts;
    Brushing / polishing: improve surface smoothness and aesthetics, suitable for 3C shells and decorative parts;
    Chemical nickel plating / chromium plating: enhance hardness and wear resistance, suitable for high-precision mechanical transmission parts;
3,Wrap with bubble wrap, store in a dry environment to prevent scratches / oxidation.

 Global Manufacturing Applications and Characteristics

Core Applications

Covering five major fields: precision electronics 3C (micro high-precision parts), general machinery (medium and large structural parts), transportation (lightweight structural parts), building and new energy (standardized connection parts), and medical devices (medical-grade precision parts). The high-end market (aviation / semiconductors) is dominated by leading enterprises in Europe, the United States, Japan, and China, while China is the core supplier in the mid-to-low-end market.

Core Characteristics

Material + structural advantages: lightweight (1/3 of steel), medium to high strength, easy to process, corrosion-resistant, 100% recyclable, lighter than cast iron and stronger than plastic in rigidity;
Manufacturing adaptability: high standardization, multi-directional assembly fit, in line with the global lightweight trend, controllable costs, and significant advantages in batch production;
Market characteristics: high-end focuses on precision / performance, mid-to-low-end focuses on cost / capacity; significant regional demand differences (high-end in Europe and the United States, mid-to-high-end in Asia, mid-to-low-end in South America and Africa), green and recyclable are core trends.
