Spex offers CNC turning for precision cylindrical parts with bar capacity up to 4" diameter. Our CNC lathes with live tooling capabilities maintain tight tolerances across prototype and production volumes. Our ISO 9001:2015 certified facility delivers both quick-turn parts and ongoing production runs with consistent quality.
Spex delivers precision CNC turning services you can count on. We u advanced multi-function turning centers and decades of expertise to produce complex cylindrical components with exceptional accuracy and efficiency.
CNC turning produces cylindrical parts where accuracy of diameters, concentricity, and surface finish is critical. The process excels at both long, slender components like shafts and shorter parts like bushings and sleeves. Live tooling capabilities add cross-holes, milled features, and precise threads to turned components. Parts that combine turned diameters with secondary features are completed efficiently in single setups.
Fluid & Gas Systems
These require precision-turned components for flow control and valve assemblies. Accurate diameters, surface finishes, and thread specifications maintain system pressure and flow requirements.
Industrial Pump & Hydraulic
These systems depend on turned components for pump assemblies and hydraulic applications. Precise fits, surface finishes, and geometric tolerances ensure proper sealing and operation in high-pressure environments.
Precision Hardware & Components
Custom fasteners and turned components where dimensional accuracy drives assembly fit and function. Consistent quality across production runs maintains assembly requirements in critical applications.
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.

This process is ideal for parts with rotational symmetry. Common examples include shafts, pins, bushings, sleeves, fittings, valve components, and custom fasteners. It's particularly well-suited for components requiring precise diameters, concentricity, and specific surface finishes.
Lead times can be affected by several factors, including the complexity of the part design, the availability of the specified raw material, the quantity ordered, the specific machining and finishing processes required, and the machine shop's current workload and scheduling capacity.
Live tooling refers to powered cutting tools (like drills or milling cutters) integrated into the lathe's tool turret. This allows for secondary machining operations, such as drilling holes perpendicular to the axis of rotation (cross-holes), milling flats or slots, or tapping threads, to be performed within the same machine setup as the turning operations.
To provide an accurate quote, machine shops typically require a detailed technical drawing or a 3D CAD model of the part. Key information includes material specifications, desired tolerances, the quantity of parts needed, and any requirements for surface finish, heat treatment, plating, or other secondary processes.
Key considerations often include the supplier's technical capabilities (machine types, live tooling, size capacity), experience with relevant materials and tolerances, documented quality systems (like ISO 9001 certification), production capacity relative to your volume needs, communication responsiveness, and overall track record for quality and on-time delivery.
