Drawing-led guidance for machining, materials, tolerances, quality and production decisions, written for engineers and procurement teams.
Use the categories above to move between machining fundamentals, drawing preparation, material choices and inspection strategy.
Mill-turn machining vs separate ops is a setup-count decision on a part that is already a turned family. Use mill-turn (live tooling on a turning center) when flats, cross-holes, slots, or wrench features must…

Aluminum CNC mask anodize for grounding is a drawing task: keep anodic oxide off the earth path. Type II (1.8-25.4 µm) and Type III (12.7-114 µm) films are electrical insulators. Hatch every grounding pad,…

CNC turning vs CNC milling is a geometry decision, not a quality ranking. Quote CNC turning when the part is built around a rotational axis: OD, ID, shoulders, grooves, tapers, and threads on 6061-T6,…

CNC internal corner radius design is how a pocket turns a corner so an end mill can reach the wall, chips can leave, and the part does not crack at a sharp notch. A…

CNC hole depth to diameter ratio (L/D) is the hole’s depth divided by its diameter, and it decides whether a standard twist drill, a peck cycle, a mill, or a deep-hole process can hold…

How to choose a CNC shop in China is a process-fit test, not a hunt for the lowest line. If the part is a 6061-T6 housing with pockets, you need milling. If it is…
