Rotary Transfer Machining Applications
Rotary transfer machines consist of a large, rotating indexing table surrounded by machining stations that carry out operations including drilling, cross-drilling, boring, turning, milling, internal and external recessing, threading, tapping, and broaching. Once a cycle is complete, the table rotates and delivers the workpiece to the next station.
Hydromat machines are known for their precision and efficiency, making them ideal for creating:
- Automotive Parts: High-precision automotive components for fuel rails, brake systems, and transmissions
- Hydraulic and Pneumatic Components: Valves, fittings, and other components used in hydraulic and pneumatic systems
- Medical Devices: Medical device components, including surgical instruments and implantable devices
- Aerospace Parts: Various high-precision engine and structural aerospace components
- Consumer Goods: Components for products like home appliances and electronics
Rotary transfer machines are highly customizable, which allows them to fabricate a diverse array of parts, including:
- Fittings/Connectors: Fittings, unions, adapters, connectors, and terminals for fluid/gas transfer and electrical connections
- Valve Components: Valve cups, seats, plates, bodies, bushings, and related parts for controlling flow; includes check valves and control valve assemblies
- Sensor Components: Sensor bosses and fittings for mounting and connecting sensors
- Electrical/Electromagnetic Components: Armatures, cores, pole pieces, flux tubes, and coil bodies for electromagnetic devices
- Fasteners: Screws, bolts, nuts, and specialized fasteners
- Shafts/Rods/Pins: Various shafts, rods, pins, and sleeves for mechanical movement and connection; includes steering pinions
- Housings/Caps/Plugs: End caps, plugs, housings, cases, and other enclosures for various components
- Other Mechanical Parts: Pistons, plungers, sleeves, rings, brackets, retainers, seals, and other miscellaneous mechanical parts
Our Rotary Transfer Machines
Greystone currently has 42 Hydromat rotary transfer machines with 10 to 16 stations. Machines can be bar fed or blank fed; our blank fed machines use both cold-headed and in-house machined blanks.
Depending on product tolerance requirements, our rotary transfer machines can include CNC programmable stations to achieve tight tolerance geometries.
