In a standard rotary transfer machine, bar stock is first segmented into blanks. The blanks are then rotated, indexing from station to station—each of which is designed for a specific machining operation. One can drill, another recess, and others finish, thread, or mill.

In contrast to a traditional lathe—in which the workpiece is rotating and the tools are fixed—rotary transfer machines typically involve the workpiece being fixed and the cutting tools rotating. Most rotary transfer systems involve from 6 to 16 stations, enabling several operations to be carried out in rapid succession for high-volume production.

Common Applications

Rotary transfer machines have widespread applications across industries such as automotive, construction, defense, aerospace, and compressor manufacturing. Common parts produced are:

- Parts turned from bar for oil, water, gas, and electronics (fittings, plumbing valves, connectors, nipples, unions, barbs, covers, rings, screws, caps, inserts, couplings, cartridges)

- Parts for hydraulic and pneumatic use in heating, ventilation, air conditioning (HVAC), fire protection systems, and environmental protection

- Parts turned to precise specifications for appliances, compressors, pumps, and other industrial systems

With their ability to perform multiple machining operations in one setup, rotary transfer machines bring unmatched productivity, consistent accuracy, and economy together—making them the first choice for precision part manufacturing in high-volume output.
