Part engineering
Design and manufacturing details
The illustrated configuration uses 7075-T6 aluminum bar stock with multi-axis turn-mill machining, grinding and natural-color anodizing. Alloy steel and other aluminum configurations can be discussed against the drawing. This 120 N·m-class configuration has critical mating-bore tolerance bands of 0.006 mm (IT5–IT6), overall shaft length tolerance of ±0.05 mm, small-end journal radial runout of ≤0.01 mm, mating-surface runout of ≤0.02 mm and concentricity of φ0.02–0.05 mm. Reamed locating holes are H7 and bolt-circle tolerance is ±0.1 mm. Mating surfaces are Ra 0.8 μm, with Ra 3.2 μm on other specified surfaces. These figures apply to this 120 N·m-class reducer configuration; requirements are reviewed for each new drawing. The process covers cutting, turning, milling, grinding and anodizing, with CMM dimensional inspection and material traceability.
- Coordinated machining and finishing
- Defined mating fits and runout requirements
- Prototype and production quantities reviewed from drawings
