Custom CNC turning parts are essential in modern manufacturing, especially for industries requiring high precision, tight tolerances, and consistent repeatability. From hydraulic fittings and automotive components to industrial machinery and electronic hardware, our CNC turning services allow manufacturers to produce complex rotational parts with reliability and efficiency.
Whether you are an engineer, buyer, or product designer, this guide explains how our CNC turning manufacturing process delivers precision components tailored to your needs.
What Are Custom CNC Turning Parts?
CNC turning is a machining process where a workpiece rotates while a cutting tool removes material to produce precise cylindrical or rotational parts. Unlike manual lathes, CNC turning machines are computer-controlled, offering high accuracy, repeatability, and efficiency.
Custom CNC turning parts are made according to customer-specific drawings or requirements. “Custom” can include:
- Unique dimensions and tolerances
- Specific materials
- Functional features like threads, grooves, or internal bores
- Surface finishes
We provide both OEM CNC turning service and ODM CNC turning service to meet diverse manufacturing needs.
OEM CNC Turning Service: Precision Parts from Your Drawings
OEM CNC turning service means you provide complete drawings, and we manufacture exactly according to specifications.
- Customer owns the design
- We handle precision machining and quality control
- No design changes unless requested
Best for:
- Finalized designs
- Stable production needs
ODM CNC Turning Service: Design and Production Support
ODM CNC turning service allows our engineers to handle both design and machining.
- Customer provides an idea, sample, or functional requirement
- We optimize the design and produce the parts
- Reduces development time and cost
Best for:
- New product development
- Customers without in-house engineering
OEM vs ODM CNC Turning: How to Choose
| Item | OEM | ODM |
|---|---|---|
| Drawings | Provided by customer | Provided or supported by manufacturer |
| Design involvement | Minimal | High |
| Customization | Medium | High |
| Time to market | Standard | Faster |
| Best use | Mature products | New or optimized products |
Tip: Have drawings? Choose OEM. Need design support? Choose ODM.

Applications of Custom CNC Turning Parts (With Real Cases)
Our precision CNC turning parts are widely used across industries, and we have successfully delivered projects for clients with strict quality and precision requirements:
-
Automotive: Shafts, bushings, and connectors，sleeve.
Case: We customized precision sleeve for an automotive client, achieving Parallelism demand ±0.01 mm tolerance for high-speed transmission systems. The parts passed rigorous durability tests and were integrated seamlessly into the client’s assembly line.
At the beginning, we used collets with liners for production, but we were unable to achieve the required parallelism. Later, we improved the process by leaving material allowance on the collet during machining, allowing the part to be 
processed on two surfaces in a single setup. This ensured symmetrical length and achieved a precision of 0.02 mm.
-
Hydraulics & Pneumatics: Fittings, valve components.
Case: For a hydraulic valve manufacturer, we produced stainless steel fittings with NPTF threading based on drawing .
