Cnc Turning Companies
Last updated: January 2026
This directory lists 114 cnc turning companies across the United States, from high-precision medical device component specialists to large-volume automotive part manufacturers.
Buyers are primarily solving for precise cylindrical component fabrication, often requiring complex features like internal threads, specific knurling patterns, or very fine surface finishes (e.g., Ra 0.8 µm). Common challenges include achieving critical concentricity between different diameters, ensuring bore straightness, and managing material characteristics to prevent chatter during deep cuts, all while optimizing cycle times for cost efficiency.
The spectrum of CNC turning suppliers is broad. You'll find job shops specializing in rapid prototyping and low-volume, high-mix work, often utilizing standard 2-axis or 3-axis lathes. On the other end are contract manufacturers focused on high-volume production, typically leveraging multi-spindle machines, Swiss-type lathes for micro-components, or machines with sub-spindles and live tooling for single-setup complex parts, aiming for lights-out manufacturing.
To engage effectively, buyers should come prepared with detailed CAD models (STEP, IGES), 2D drawings with clear GD&T callouts, material specifications, and anticipated annual volumes. Suppliers, in turn, expect clarity on critical features, surface finish requirements, and any post-machining operations like heat treatment, plating, or passivation, to provide an accurate and comprehensive quote.
A significant trend in the CNC turning sector is the increased adoption of automation, particularly robotic tending for machine loading/unloading and integrated in-process gauging. This is driving down labor costs, improving consistency, and enabling longer unattended run times, pushing shops towards greater efficiency and responsiveness for higher-volume orders.

How to Choose a Company
- Verify their ability to hold specified concentricity and runout tolerances, particularly for assemblies where precise alignment is critical, by requesting example CMM reports or first-article inspection data.
- Assess their machine fleet: Do they have live tooling capabilities for secondary milling or drilling operations, or sub-spindles for back-side machining, enabling single-setup manufacturing and reducing part handling?
- For industries like aerospace or medical devices, require proof of AS9100 or ISO 13485 certification, respectively, ensuring their quality management system meets stringent regulatory and performance standards.
- Scrutinize their material expertise. A common red flag is a shop quoting highly specialized alloys (e.g., Inconel, Titanium) without demonstrating prior experience or specific tooling designed for those challenging materials, leading to poor surface finish or high scrap rates.
- Inquire about their in-house post-processing capabilities (e.g., deburring, tumbling, passivation) versus what they outsource. Extensive reliance on external vendors can introduce lead time variability and quality control risks.
- Always request a sample or prototype of a representative part, especially if your design has critical features or demanding surface finish (Ra) requirements, before committing to a full production run. This helps validate their process control.
Frequently Asked Questions
How do I accurately specify surface finish for CNC turned parts beyond a simple Ra value?
While Ra (average roughness) is common, consider specifying Rz (mean peak-to-valley height) or Rt (total roughness) for critical sealing or bearing surfaces. Also, indicate the machining process (e.g., turned, ground, polished) and any lay direction requirements using symbols on your drawing to avoid ambiguity and ensure the supplier understands the functional need.
When should I consider a supplier with multi-axis capabilities or a Swiss-type machine for my turned parts?
Multi-axis machines (e.g., with live tooling or sub-spindles) are ideal for complex parts requiring milling, drilling, or off-center features in a single setup, reducing cost and improving accuracy by minimizing part handling. Swiss-type lathes are best suited for small, slender, high-precision parts (typically under 1.25" diameter) where exceptional straightness, tight tolerances, and fine surface finishes are paramount, such as medical implants or electronic connectors.
What are the common pitfalls when quoting CNC turned parts based solely on hourly machine rates?
Focusing only on hourly rates can be misleading. Consider the machine's capabilities (e.g., older 2-axis vs. modern multi-axis with live tooling), material waste, setup time, tooling costs, and included quality inspections. A lower hourly rate on an inefficient machine or one requiring extensive secondary operations might result in a higher overall part cost and longer lead times.
What documentation should I provide to get the most accurate and competitive quote for CNC turning?
Always provide a 3D CAD model (STEP, IGES) alongside a fully dimensioned 2D engineering drawing. The drawing is crucial for communicating critical dimensions, GD&T callouts, surface finish requirements, material specifications (including specific alloys and temper), and any necessary heat treatment or plating. Also, specify estimated annual volume and required lead times for both prototypes and production.
How can I assess a CNC turning supplier's capacity to scale from prototype to high-volume production?
Inquire about their machine mix (dedicated production machines vs. versatile job shop equipment), their approach to tooling (soft jaws for prototypes vs. hard tooling for production), and their quality control processes for different volumes (e.g., first article inspection vs. in-process statistical process control). A supplier with robust automation, multiple similar machines, and a clear scaling plan indicates better readiness for volume.
