S-320AT Inline Auto Lead Cutter Machine
What Is This Machine?
The S-320AT is an inline automatic lead cutter designed for post-wave-soldering PCB assembly lines. It automatically cuts component leads one by one along a programmed path, vacuums up trimmed waste, and recycles pins — eliminating the need for manual post-solder lead trimming entirely.
