Multi-Spindle Machining for High-Volume, Precision Parts

Manufacturers across industries rely on Greystone’s multi-spindle machining capabilities to fabricate their high-volume, precision parts. Also known as screw machines, multi-spindle machines are often used to manufacture intricate parts with tight tolerances, including those used in safety-critical applications.  

Multi-spindle machining operations are conducted at Greystone of Lincoln, an IATF 16949 certified, 75,000 square-foot facility that houses over 100 state-of-the-art multi-spindle, single-spindle, rotary transfer and grinding machines.

To maximize the potential of our best-in-class equipment, Greystone’s team of experienced engineers leverage tooling and automation that is custom-designed and manufactured in-house. Our significant capital investments and deep machining expertise allow us to work flexibly and deliver high-quality, cost-effective service.

Multi-Spindle Machining Applications

Multi-spindle machines use six or eight spindles to perform discrete tooling operations simultaneously. The spindles and workpieces are housed inside a drum that rotates to deliver workpieces to their next, programmed workstation. Unlike single-spindle machines, which are only capable of producing one part at a time, multi-spindle machines can work on and manufacture multiple parts at the same time.

By design, these machines have exceptionally fast cycle times. Spindle-stopping and cross-drilling operations play a particularly important role in minimizing machining time. Luckily, speed doesn’t come at the expense of precision: multi-spindle machines are inherently accurate, which makes them suitable for producing high-quality safety-critical components.

Multi-spindle machines are used to create an expansive range of parts including, but not limited to:

• 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
• 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: Shafts, rods, pins, and sleeves for mechanical movement and connection; includes steering pinions
• Housings/Caps/Plugs: End caps, plugs, housings, cases, and other enclosures
• Other Mechanical Parts: Pistons, plungers, sleeves, rings, brackets, retainers, seals, and other miscellaneous mechanical parts
