CNC turning service
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.

Surface Finishes for CNC Turning
Improve the performance of the component by choosing surface finishes that enhance the roughness, hardness, chemical resistance and aesthetic properties of the finished product.
Tolerances for CNC turning
Our approach to CNC machining follows ISO 2768 standards.
|Limits for nominal size||Plastics (ISO 2768-m)||Metals (ISO 2768-f)|
|0.5mm* to 3mm||±0.1mm||±0.05mm|
|Over 3mm to 6mm||±0.1mm||±0.05mm|
|Over 6mm to 30mm||±0.2mm||±0.1mm|
|Over 30mm to 120mm||±0.3mm||±0.15mm|
|Over 120mm to 400mm||±0.5mm||±0.2mm|
|Over 400mm to 1000mm||±0.8mm||±0.3mm|
|Over 1000mm to 2000mm||±1.2mm||±0.5mm|
|Over 2000mm to 4000mm||±2mm|
|*Please clearly indicate tolerances for nominal sizes below 0.5mm on your technical drawing.|

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.
