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)

Anodizing: natural color/black/silver, enhancing corrosion resistance and appearance texture

Sandblasting/Drawing: Optimize surface visual effect, conceal slight knife marks
