Quick Answer
Automated battery recycling requires CNC machining of wear-resistant tooling and robotic disassembly fixtures with chemical compatibility for electrolyte exposure and precision gripping accuracy ±0.10 mm. Critical components include diamond-coated cutting tools and PTFE-lined handling fixtures.
Definition
CNC machining for battery recycling automation involves specialized tooling that safely disassembles, cuts, and separates battery pack components for material recovery. This includes tools resistant to hydrofluoric acid (HF) generated from lithium-ion electrolyte decomposition.
How It Works
Diamond-Coated Tool Machining: CNC grinding of diamond-coated cutting tools for aluminum battery case sectioning.
Chemical-Resistant Fixture Machining: Machining PTFE and PEEK fixtures that resist electrolyte corrosion.
Robotic Gripper Machining: Precision machining of adaptive grippers handling various battery pack sizes.
Material Separation Tooling: CNC machining of screens, classifiers, and sorters for cobalt, nickel, lithium recovery.
