GB Plug Copper Part Grooving: Process, Accuracy and Machine Selection

GB three-pin flat plug blades have strict grooving requirements: slot position deviation causes loose assembly or safety compliance failures. The first selection step is defining the blade groove structure — single slot, multi-slot or shouldered profiles — which determines spindle count and tooling.

For accuracy: plug blades are small copper parts where clamping rigidity is critical. Fixtures must be custom-machined to the blade profile to prevent chatter; groove depth should be cut in multiple passes, with real-time inspection monitoring critical dimensions and alarming on tool wear to stop batch defects.

For efficiency: single-side 2-axis models suit small to medium batches; mass production favors double-side or multi-axis configurations that complete multiple grooves in one clamping. Zhongtong's modular machines range from single-side 2-axis to double-side 11-axis, combinable to your capacity targets.
