Description
Fillet (Radii)
The recommended minimum internal fillet is 0.5 mm. Larger fillets (up to 3 mm or more) can improve tool accessibility and reduce stress concentration in the part.
Threads and Tapped Holes
External and internal threads can be precisely cut. Standard thread sizes start from M1.6, ensuring that the thread length is at least 1.5 times the diameter for stability.
Minimum Wall Thickness
Metal: Minimum wall thickness is 0.8 mm;
Plastic: Minimum wall thickness is 1.5 mm, to ensure structural integrity without affecting the machining process.
Plastic: Minimum wall thickness is 1.5 mm, to ensure structural integrity without affecting the machining process.
Text
The height of engraved characters should be at least 2 mm, with a depth of at least 0.5 mm, to ensure clarity and readability after machining.
Holes
Minimum hole diameter is 0.5 mm. For deep holes, maintain a diameter-to-depth ratio of 1:10 to avoid tool deflection and ensure hole quality.
