CNC Machining Tolerances
Typical machining tolerances fall within the range of ± 0.005
inches or 0.13 millimeters.
Tolerances represent the allowable variation for a specific
dimension.
For instance, if a CNC machining tool has a tolerance of ± 0.01
millimeters, it means that the tool
can deviate by 0.01 millimeters in each cut.
When provided with a drawing, Our CNC machining service can achieve
CNC parts with tolerances
as tight as ± 0.0002 inches.
In the absence of a drawing, all CNC parts are manufactured
according to our ISO 2768 medium
standard. We can also work to even tighter tolerances, such as ±
0.025 millimeters or ± 0.001
inches, when an engineering drawing specifies critical features.
| CNC Turning Tolerances |
| Limits for nominal size | Plastics | Metals |
| 0.5mm* to 3mm | ±0.1mm | ±0.05mm |
| Over 3mm to 6mm | ±0.1mm | ±0.05mm |
| Over 6mm to 30mm | ±0.2mm | ±0.10mm |
| Over 30mm to 120mm | ±0.3mm | ±0.15mm |
| Over 120mm to 400mm | ±0.5mm | ±0.20mm |
| Over 400mm to 1000mm | ±0.8mm | ±0.30mm |
| Over 1000mm to 2000mm | ±1.2mm | ±0.50mm |
| Over 2000mm to 4000mm | ±2.0mm | |
| *Please clearly indicate tolerances for nominal sizes below 0.5mm
on your technical drawing. |

FAQ's
1. What is the difference between rough turning and finish turning?
Rough turning and finish turning are two distinct phases in the CNC
turning process, each serving
a specific purpose.
Rough turning is the initial stage where the primary objective is
to efficiently remove as much
material as possible from the workpiece.
This process prioritizes material removal over precision and
surface finish.
Its purpose is to rapidly shape the workpiece and bring it closer
to the desired dimensions,
allowing for more efficient subsequent machining operations.
On the other hand, finish turning is the concluding phase of the
turning process.
Here, the emphasis shifts towards achieving the desired level of
smoothness and accuracy in the
final product.
Finish turning fine-tunes the workpiece's surface finish and
dimensional accuracy, ensuring that
it meets the exact specifications and requirements.
In summary, rough turning focuses on material removal and shaping,
while finish turning
concentrates on achieving the desired precision and surface
quality.
2. Advantages of CNC Turning
CNC turning offers several advantages, making it a valuable
machining process:
1. Versatility: CNC turning centers can be equipped with rotating
cutters like end mills and drills,
expanding their capabilities to handle asymmetrical features and
various machining tasks.
This versatility increases production efficiency and
cost-effectiveness.
2. Speed and Efficiency: CNC turning enables faster production,
reducing lead times and
increasing overall efficiency. The automation and precision of CNC
systems contribute to
streamlined operations.
3. Radial Symmetry: Achieving radial symmetry in parts is
relatively easy with CNC turning.
This capability simplifies the machining of cylindrical and
symmetrical components.
4. High Precision: Mounting the workpiece in a chuck allows for
high precision during CNC turning
operations. This results in accurate and consistent part
dimensions.
5. Superior Surface Finish: CNC turning often produces a superior
surface finish on workpieces,
enhancing their overall quality and appearance.
6. Safety: CNC turning offers a safer machining environment
compared to manual operations,
as it minimizes the need for direct human involvement in the
machining process.
In summary, CNC turning provides versatility, speed, precision, and
superior surface finish,
making it a preferred choice for various machining needs.
