Quick Answer
EV battery recycling equipment requires CNC machining of D2 tool steel and 4140 steel for cutting blades, crushing chambers, and separation tools with wear part tolerances of ±0.02 mm. Critical features include disassembly fixture precision ±0.05 mm and cutting edge sharpness to safely dismantle battery packs.
Definition
CNC machining for battery recycling involves specialized tooling for safe battery pack disassembly, module separation, and material recovery. This includes cutting tools for aluminum enclosures, crushing equipment for cells, and sorting fixtures for material separation.
How It Works
Tool Steel Machining: CNC grinding of D2 steel cutting blades with 0.02 mm edge accuracy.
Crushing Chamber Machining: 4140 steel machining for high-impact crushing chambers.
Disassembly Fixtures: Precision aluminum fixtures for safe battery pack dismantling.
Separation Tooling: CNC-machined screens and separators for material sorting.
