New energy lithium battery production involves complex three dimensional structural parts such as aluminum alloy shells and stacking fixtures. Two dimensional optical measuring equipment cannot capture spatial position tolerance of curved battery components, triggering assembly mismatch and finished battery safety risks. This article clarifies all typical battery production scenes that demand coordinate measuring machine deployment.
New energy vehicle battery aluminum shells contain multiple curved surfaces and assembly positioning holes with strict spatial tolerance limits. Coordinate measuring machine conducts full three dimensional scanning of shell workpieces, detecting flatness verticality and hole position deviation in one inspection cycle. Stable three dimensional measurement data avoids battery shell assembly dislocation during finished pack production and reduces product rejection rate.
Electrode forming molds used in planetary centrifugal mixer slurry processing own complex three dimensional curved inner cavities controlling coating thickness uniformity. Two dimensional measuring tools fail to detect cavity radian and depth error, while coordinate measuring machine completes full spatial dimension verification of mold core. Standardized three dimensional inspection stabilizes electrode coating consistency and improves battery energy density uniformity.
Battery cell stacking fixtures demand ultra high positioning precision to guarantee consistent cell interval during automatic assembly. Coordinate measuring machine with multi angle rotating probe detects hidden deep hole and multi plane positioning structure of stacking fixtures. Regular calibration through cmm measuring machine eliminates fixture deformation error and maintains stable battery assembly yield for long term mass production.
