Custom CNC Milling Part Service Stainless Steel Machining CNC Part Professional
Manufacturer Milled CNC Parts
CNC milling is a machining process that combines computer numerical control (CNC) machining
systems with a multi-point cutting tool or milling cutter.
This method, classified under CNC machining, entails securing the workpiece on a machine bed
and removing material from a solid block to fabricate various products.
These products can be crafted from a wide range of materials, including glass, metal, plastic,
wood, and specialized materials.

CNC Machining Tolerances
Tolerances are not standardized across all processes and materials.
The final tolerances on your part depend on various factors, such as part size, design complexity,
the number and size of features, materials used, surface finish, and the manufacturing process
employed.
Once your order is confirmed, we conduct a Design for Manufacturing review to identify areas that
may need modification for better manufacturability.
It's helpful if you can specify which areas in your design have critical tolerances that must be met
and which can be adjusted, if necessary, to optimize production time and cost.
CNC Milling 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. A Brief Overview of CNC Machining Parameters
In CNC machining, many parameters are determined by the machine operator during the
generation of G-code.
Among these parameters, we will focus on the build size and accuracy of CNC machines.
CNC machines are known for their relatively large build areas, particularly when compared to
3D printers. CNC milling systems, for instance, are capable of machining parts with dimensions
of up to 2,000 x 800 x 100 mm (78” x 32” x 40”), while CNC turning systems can handle parts
with diameters of up to Ø 500 mm (Ø 20’’).
One of the notable advantages of CNC machining is its ability to produce parts with exceptional
accuracy and tight tolerances. CNC machines can achieve tolerances that are even less than
half the diameter of an average human hair, which is approximately ± 0.025 mm or .001’’.
In cases where the tolerance is not specified in the technical drawing, the operator typically
machines the part with an accuracy level of 0.125 mm (.005’’).
2. Delivery Time and Quotation Turnaround
Our delivery time and quotation process are influenced by the complexity of your project.
For low-complexity parts, expect a lead time of 2-3 days. As complexity increases, the lead time
can range from 2-5 days. High-complexity parts may require a lead time of 5-15 days.
Quotation turnaround time varies based on complexity as well. For straightforward designs,
we can provide a quote within 1 business day or even faster. However, for more intricate projects,
the quoting process may take 3 or more business days.
If you have a design that needs assessment and a quote from our team, please don't hesitate
to contact us.
3. Ensuring Part Quality
Our commitment to ensuring the quality of your parts includes a comprehensive approach:
1. Design for Manufacturing (DFM) Review: After your order is confirmed, we conduct a thorough
DFM review to identify and address any potential issues that could impact part quality.
2. Incoming Material Inspection: All incoming materials undergo rigorous inspection and
verification using advanced testing equipment to ensure they meet our quality standards.
3. Final Inspection Reports: Before shipment, each part undergoes a final inspection.
We provide detailed inspection reports, giving you complete visibility into the quality of your parts.
4. Real-time Inspection Data: We have the capability to share inspection data with you in real-time.
This collaborative approach allows us to address any quality concerns during the production process,
ensuring that your specifications and expectations are met.
Our commitment to quality control is integral to delivering parts that meet your exacting standards.
