CNC Machining Milling Parts Metal CNC Machined Parts Steel Precision

CNC Components

 

Our precision CNC machining services cater to the production of intricate finished parts,

components, and tools for processes like plastic injection molding and pressure die casting.

 

Additionally, CNC manufacturing is employed for secondary tasks such as drilling, tapping, and

milling operations on machined parts or those created through alternative methods.

 

CNC machine tools encompass a diverse range of specialized types, each designed to execute

various operations on raw materials. Nevertheless, CNC mills, as the most prevalent and versatile

multi-axis machines, constitute a significant part of our daily operations at we.

 

Product Details

 

CNC milling machines excel at cutting a wide range of materials, including aluminum, bronze,

copper, ceramics, plywood, various steel types, stone, wood, zinc, and numerous engineering

materials.

This versatility makes them perfect for crafting prototypes during product development.

With CNC milling, you can easily fine-tune and make precise adjustments until you achieve the

desired final product, offering accuracy and efficiency throughout the manufacturing process.

ability to rapidly manufacture precise parts in production-grade materials. Typical CNC parts,

include:

 

1. Housings and enclosures
2. Brackets
3. Fixtures for manufacturing
4. Gears and bearings
5. Internal mechanical components
6. Medical instrumentation

Company Profile

FAQ's

 

1. How does our pricing compare to other suppliers?


When it comes to pricing, we offer a competitive advantage. Typically, our prices for plastic

injection mold tools and CNC machined/turned parts are 25-45% lower than those of suppliers

in North America and Europe.

 

In contrast to Chinese suppliers, we do not compete solely on price. Instead, we prioritize

delivering the utmost quality, rapid responsiveness, and professional results to our clients.

 

2. How soon can I receive my parts?


We can produce quality parts in as little as two weeks if you provide us with complete 2D and

3D CAD models. However, more complex parts with special features may have longer lead times.

Request a quote to receive more precise lead times based on your specific project.


Regarding shipping, our primary method is air freight, which typically takes a few days for

delivery from China to Europe or North America.

 

3. What tolerances can be achieved?


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.

Here are some general tolerance guidelines:

 

General tolerances for CNC machining in metal and plastic.
Tolerances for plastic injection molding.
Reference charts for CNC machining of metals and plastic injection molding materials.
General tolerance for metal 3D printing is +/- 0.5mm.
A shrinkage rate of +/- 0.15% can be expected for vacuum casting.
All manufacturing and technical specifications must be clearly defined in the 2D drawings to be

followed accurately.
