CNC Turning Service: Precision Manufacturing Solutions
CNC turning is a subtractive manufacturing process where a cutting tool removes material from a rotating workpiece to create cylindrical parts with high precision. Unlike CNC milling, where the tool rotates and the workpiece remains stationary, turning involves a stationary cutting tool and a rotating workpiece.
The process is controlled by computer numerical control (CNC) systems that follow programmed toolpaths to achieve exact specifications. This automation ensures exceptional repeatability and precision, making CNC turning ideal for creating components with circular cross-sections and complex external or internal features.
How CNC Turning Works
CNC turning transforms raw materials into precisely crafted cylindrical components through computer-controlled machining. It's process follows these essential steps:
The workpiece is secured in a chuck or collet that rotates at high speed
A stationary cutting tool moves along two axes (X and Z) to engage the material
The tool removes material as the workpiece rotates, creating the desired shape
Multiple tools can be used sequentially for different operations
The CNC controller precisely coordinates all movements based on the programmed instructions
Advanced CNC turning centers can also incorporate live tooling capabilities, allowing for milling and drilling operations without repositioning the workpiece, significantly enhancing efficiency and precision.

CNC Turning FAQs
CNC turning and milling differ primarily in how the workpiece and cutting tool move. In CNC turning, the workpiece rotates while a stationary cutting tool removes material. This makes turning ideal for cylindrical parts. In CNC milling, the cutting tool rotates while the workpiece remains stationary, making it better suited for prismatic parts with complex features. Many modern CNC turning centers combine both capabilities with live tooling options.
Our standard CNC turning tolerances are ±0.05mm, but we can achieve precision tolerances of ±0.025mm and ultra-precision tolerances of ±0.005mm for critical dimensions. The achievable tolerance depends on several factors including material properties, part geometry, feature size, and specific dimension requirements. We recommend discussing your tolerance needs during the quoting process.
We have no strict minimum order quantity (MOQ) requirements. We can produce as few as one prototype part or thousands of production components. However, the per-unit cost is typically higher for very small quantities due to setup and programming costs being distributed across fewer parts. We're happy to provide pricing options for different volume scenarios to help you make the most cost-effective decision.
Yes, we provide material certifications (mill certs) and detailed inspection reports upon request. Our standard quality process includes first article inspection and batch sampling according to industry standards. For critical applications, we can perform 100% inspection and provide comprehensive measurement data for all specified dimensions. Additional documentation such as material traceability, process certifications, and special testing reports are available to meet specific industry requirements.
Lead times for CNC turned parts vary based on complexity, quantity, material availability, and current production schedule. Typical lead times range from 3-5 business days for rush prototypes to 2-3 weeks for standard production orders. We offer expedited services for time-critical projects. Please contact us with your specific requirements for an accurate timeline estimate.
We accept most standard CAD file formats including STEP, IGES, Parasolid, SolidWorks, AutoCAD, and others. 3D models are preferred for complex parts, but we can also work from 2D drawings with complete dimensioning and tolerancing. For optimal results, we recommend providing both 3D models and 2D drawings with GD&T callouts for critical features.
