CNC turning service
Source high-performing parts in over 50 distinct metals and plastics through V1's network of advanced CNC turning specialists. Tight tolerances can be achieved, ranging from ±0.0008 inches.
What is CNC turning?
CNC turning creates components by clamping a raw material onto a spindle that spins it while cutting tools remove the material. This technology is perfect for producing symmetrical components along their central axis. Turned components are usually manufactured faster and at a lower cost than milled components.

Our CNC turning adheres to high standards
We create your bespoke components following rigorous manufacturing standards. We ensure that all parts and processes comply with the V1 Standard. We provide a comprehensive inspection report with each order, verifying these requirements.
Following machining, parts may be left in their machined state or undergo a post-processing process to improve the surface properties or aesthetics as specified by the customer's requirements in the purchase order.
In-house quality checks are carried out after production, before the MP sends the custom parts to either our facilities or their final destination, to ensure every component is manufactured to the order's specifications and the V1 Standard.
At this stage, any requested documentation is completed, assuring the conformity of the parts before the order is dispatched.
