,6061 T6 precision cnc machining parts
M3 aluminum alloy precision CNC machined square positioning block - engineered for superior performance in demanding industrial applications.
- Select suitable aluminum grades: 6061/6063 (general-purpose), 7075-T6 (high-strength), 5052 (precision micro)
- Remove stress from raw material through natural/artificial aging or annealing to prevent deformation during processing
- Uniformly leave machining allowance and use soft pads for symmetrical clamping to prevent damage and deformation
- Select hard alloy/diamond-coated tools with increased rake angle to prevent tool adhesion
- Match cutting parameters: high speed and high feed for 6 series/5 series aluminum, low speed and low feed for 7 series aluminum
- Use high-pressure coolant/cold air cooling with timely chip removal to avoid thermal deformation and surface scratches
- Follow "coarse first, then fine, surface first, then edge" principle with climb milling for finish machining
- Leave 0.1-0.3mm finish allowance and conduct real-time inspection using appropriate measuring instruments
- Manual/ultrasonic deburring to ensure proper assembly fit
- Common surface treatments for aluminum alloys include:
- Anodizing - general protection, improved corrosion resistance
- Hard anodizing - thickened oxide film, high wear and scratch resistance
- Electrophoretic coating - good insulation, smooth surface
- Spray painting/powder coating - rich colors, impact resistance
- Passivation/sealing - improved sealing and corrosion resistance
- Brushing/polishing - improved surface smoothness and aesthetics
- Chemical nickel plating/chromium plating - enhanced hardness and wear resistance
- Wrap with bubble wrap and store in dry environment to prevent scratches and oxidation
Core Applications: 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).
Core Characteristics: Material + structural advantages including lightweight (1/3 of steel), medium to high strength, easy processing, corrosion resistance, 100% recyclable. Manufacturing adaptability with high standardization, multi-directional assembly fit, and significant advantages in batch production.
