Spex produces complex turned parts up to 2-5/8" diameter using Davenport multi-spindle automatic screw machines. Our multi-spindle capabilities enable simultaneous operations on 5 spindles, reducing cycle times by 80% compared to single-spindle turning. The multi-spindle department maintains tolerances to ±0.005" while achieving production rates up to 400 pieces per hour. Our ISO 9001:2015 certified machine shop specializes in high-volume production runs exceeding 10,000 pieces.
Multi-spindle machines perform 5 simultaneous operations per cycle, and index workpieces through 5 positions, completing turning, drilling, threading, and forming operations in a single cycle. Each spindle position contains dedicated tooling optimized for specific operations, eliminating setup changes between features. This parallel processing delivers finished parts at rates up to 400 pieces per hour.
Multi-spindle machining produces high-volume precision components where production efficiency drives cost reduction. The process completes complex features in single cycles, achieving tight tolerances on turned diameters, threads, cross-holes, and formed features. Parts combining multiple operations benefit from the parallel processing capabilities of 5-spindle production.
Industrial Pump & Hydraulic Systems
Pump systems require high-volume precision components machined from carbon and stainless steels. Multi-spindle machines produce shaft components, housings, and hydraulic fittings with tolerances to ±0.0005" for proper system operation.
Power & Electrical
Power distribution systems use brass and aluminum components produced at high volumes. Multi-spindle machining creates terminal connectors, bushings, and fasteners combining turned features with cross-holes and threads. Production rates of 400 parts per hour reduce component costs.
Agricultural & Heavy Equipment
Agricultural equipment relies on robust steel and stainless steel components produced in large quantities. Multi-spindle operations manufacture pins, bushings, and hydraulic fittings with formed features and precise thread specifications for reliable field performance.
Our quality control team inspects parts throughout the production process to ensure they meet customer specifications. Our ISO 9001:2015 certified quality system maintains consistent standards from first article to production runs. Documentation includes material traceability, inspection reports, and First Article Inspection Reports (FAIR) based on customer requirements.

The primary advantage of multi-spindle machining is its incredible speed and efficiency for high-volume production. By machining multiple parts simultaneously, cycle times are significantly reduced compared to single-spindle machines, leading to a lower cost per part at large quantities. This makes it exceptionally cost-effective for meeting high-demand production schedules.
This process is primarily chosen for high-volume production runs of turned parts, often those with relatively simple to moderately complex geometries. It excels where speed and cost-effectiveness at scale are critical. Common examples include fittings, valve components, automotive parts, fasteners, and other components needed in large quantities (often hundreds of thousands or millions).
Lead time for multi-spindle projects is heavily influenced by initial setup complexity and tooling requirements, which can be more involved than single-spindle setups. Material availability and order quantity are also key factors. Once set up, however, the per-piece cycle time is extremely fast, allowing large volumes to be produced quickly. Required secondary operations and overall shop capacity also affect the schedule.
To provide an accurate quote for multi-spindle work, suppliers need detailed information, with production volume being particularly critical. A technical drawing or CAD model specifying dimensions and tolerances is essential, along with the exact material specification. Clearly state the required quantity (often high volumes are assumed) and estimated annual usage (EAU), desired delivery schedule, and any secondary operation or specific quality documentation needs.
Choosing a multi-spindle supplier requires evaluating their specific expertise and capacity for high-volume work. Assess their machine capabilities, tooling expertise, and experience with your required materials and part complexity. Verify their quality systems (like ISO 9001 certification) and their ability to maintain consistency across large production runs. Consider their track record for reliability, on-time delivery, and their capacity to handle potentially multi-million piece orders efficiently.
