Product Details

1. The part is a testing fixture for a research institute, made of 606L aluminum alloy. It measures 3,200 mm in length, 450 mm in width, and 235 mm in height, with a required surface form error of 0.05 mm.
2. Challenges: High accuracy is required for surface error inspection, with a roughness requirement of Ra 3.2; the part dimensions are large, and machining is prone to deformation.
3. A CNC gantry milling machine XK204 is used for rough machining, aging treatment, semi-finish machining, finish machining, inspection, and re-machining followed by another round of finish machining. Subsequently, portable three-coordinate measuring equipment is employed for inspection, after which final finish machining is performed to ensure compliance with the required surface accuracy specifications.
