Cincinnati Milacron 3-424-2128A Floppy Disc Drive

The Cincinnati Milacron 3-424-2128A Floppy Disc Drive is a TEAC FD-235HF 5.25-inch floppy disk drive used as an OEM replacement in Milacron Acramatic CNC controls. Identified by TEAC model FD-235HF and Milacron part numbers 19307775-29 and P981001, this unit appears in vendor listings as REV A/B variants of the same drive assembly. As a legacy disk drive, it is designed to read and write data on 5.25-inch disks to support loading CNC software, parameters, and data files for older Acramatic controllers. The part is commonly found in surplus and repair inventories and is described by multiple sellers as a TEAC floppy disk drive compatible with Cincinnati Milacron equipment, making it a practical option for technicians restoring vintage milling and machining centers that rely on the Acramatic family. When selecting this part, buyers should confirm the machine’s controller revision and disk format compatibility to ensure proper operation within the Milacron system. This drive is typically used as an in‑machine spare or replacement component in legacy CNC tooling rather than a current-production storage solution, reflecting its place in older Milacron control ecosystems.
