CNC Stainless Steel Machining Part CNC Customized Part Milling CNC Parts
The process of our custom CNC machining service involves leveraging the predominant
subtractive manufacturing technology of CNC machining. This method is particularly effective
in crafting bespoke metal and plastic parts for both prototyping and production needs.
Through the utilization of CAD modeling software and G-code, CNC milling and CNC turning
machines meticulously remove material from solid workpieces with precision and efficiency.
Our service excels in delivering sturdy components with stringent tolerances and diverse
material properties, both mechanical and chemical. Its applicability extends seamlessly to
one-off projects and low-to-medium volume production, facilitated by automation and high
repeatability.
Product Details
CNC machining materials are generally grouped into three primary categories: plastics, soft metals,
and hard metals. This classification includes materials such as aluminum, bronze, copper, ceramics,
plywood, steel, stone, wood, zinc, and various others.
Preference is often given to materials that are considered easy to work with and possess
advantageous properties compared to alternative options.

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. Can passivate my parts?
Passivation is a treatment that alters the surface chemistry of certain types of metals.
We provide passivation services for corrosion protection, enhanced durability, improved
aesthetics, and more.
2. How much import duty will I need to pay for my goods?
The specific import duty for your goods varies, and there isn't a one-size-fits-all answer.
For customers in Australia, new CHAFTA regulations enable a gradual implementation of
duty-free imports.
Import duties are diverse and contingent on the type of goods being imported.
Globally, most countries adhere to international Harmonized System (HS) codes, categorizing
almost all commercial trade goods.
3. Does you provide export molds?
Yes, we do provide export molds. It's essential to note that our tooling is designed to be compliant
with our Modular Unit Dies (MUD). This implies that the tools have a uniform base size.
Therefore, customers should be ready to receive tools of that size to ensure compatibility with their
machines.
