Specialized In Providing Custom Metal Fabrication And Sheet Metal Manufacturing, Quality Metal Machining Services Since 2007
Aluminum alloy CNC precision structural parts (6061/7075 aluminum alloy), mainly used for equipment clamping, positioning or connection
Structure and accuracy requirements
Exterior structure: arc-shaped body+square mounting seats at both ends, including flat, arc-shaped, and stepped surfaces
Characteristics of pore system:
Install threaded holes at both ends (for fixing)
Intermediate positioning pin hole/screw hole (for precise positioning or locking)
Tolerance requirements:
Dimensional tolerance: ± 0.05mm (ensuring assembly consistency)
Hole position accuracy: ± 0.02mm (ensuring coaxiality/positional accuracy with mating parts)
Geometric tolerance: Flatness ≤ 0.03mm, parallelism ≤ 0.03mm, arc surface contour ≤ 0.05mm
Surface quality:
Surface roughness: Ra ≤ 1.6 μ m (visible fine cutting patterns, no obvious cutting marks)
Edge chamfer: C0.3~C0.5 (to prevent sharp edge scratches and meet assembly safety requirements)
No burrs, no knife tumors, no deformation

CNC Customized processing services for
Cutting: Aluminum alloy sheet/square material, cut according to the shape of the part+machining allowance (leave 0.5-1mm on one side)
Deburring: Remove burrs from the cutting edge to avoid scratching during clamping
CNC process:
Milling reference plane
Rough milling outline
Rough drilling threaded bottom hole, positioning hole
Tools: Hard alloy end mill (φ 10/φ 6), high-speed steel drill bit
Parameters: Vc=150~200m/min, fz=0.15~0.2mm/tooth, ap=1~2mm
Clamping: Use customized fixtures (to avoid clamping deformation and ensure the accuracy of hole position and shape)
CNC process:
Fine milling all flat, curved, and stepped surfaces to meet the requirements of size and roughness
Precision hinge positioning pin hole ensures positional accuracy and roundness
Tapping: Install threaded holes (using an extrusion tap to ensure thread strength and accuracy)
Chamfering: All sharp edges are chamfered C0.3~C0.5
Cutting tools:
Precision milling: Hard alloy high gloss aluminum milling cutter (unequal pitch, anti vibration)
Tapping: Squeezing tap (suitable for aluminum alloy, chip free, high thread accuracy)
Parameters: Vc=300~400m/min, fz=0.05~0.1mm/tooth, ap=0.2~0.5mm (high-speed small feed, ensuring smooth surface)
Surface treatment of aluminum alloy parts
Anodizing: natural color/black/silver, enhancing corrosion resistance and appearance texture
Sandblasting/Drawing: Optimize surface visual effect, conceal slight knife marks
