Custom Milling Parte CNC Aluminium Machined Parts CNC Machining Service
The essence of CNC machining, or Computer Numerical Control machining,
lies in its subtractive manufacturing approach, automatically eliminating material from raw
stock based on computer-generated instructions.
Typically, CNC machines fall into two categories: those that maintain the raw stock in a fixed
position while rotating the cutting tool, and those that rotate the raw stock while maneuvering
it against a stationary tool. Numerous adaptations and hybrid methods exist, enabling certain
machines to utilize both techniques concurrently, facilitating the production of parts with
complex features.

Company Profile
FAQ's
1. What are the minimum and maximum dimensions you can machine?
We offer CNC milling (3-axis, 3+2-axis and 5-axis) and turning. Milled parts can be machined up
to 2000 x 1500 x 200 mm (78.7 x 59.0 x 7.8 in.) for 3/3+2 axis CNC milling.
For 5-axis milling, the maximum part size is 650 x 650 x 300 mm (25.5 x 25.5 x 11.8 in.).
The maximum diameter for CNC turning is 431mm (17 in.), length 990 mm (39 in).
Minimum part dimensions recommended are around 0.39 x 0.39 x 0.39 in. (10 x 10 x 10mm).
The minimum for feature dimensions is 0.5 mm.
We are limited to a 1000 mm (39 in.) maximum size for parts on our platform.
If you need higher dimensions, you can place the request through our sales.
2. How much does CNC machining cost?
The cost of CNC machining is influenced by factors such as complexity, quantity, and lead time.
To obtain an accurate quote, we encourage you to submit a 3D CAD model, allowing us to provide
an interactive quote with design for manufacturability (DFM) feedback.
Leveraging proprietary software and automated fixturing processes, we eliminate upfront
non-recurring engineering (NRE) costs. This makes CNC machining cost-effective for quantities as
low as 1 to 200 parts. While prices may compare similarly or slightly higher than 3D printing, CNC
machining offers superior material properties and surface finishes.
3. How quickly can I get my parts?
We can produce quality parts in as little as two weeks if complete 2D and 3D CAD models are provided.
However, more intricate parts with special features may require additional time. For more precise lead
times based on your project, request a quote.
Regarding shipping, the majority of our shipments are via air freight, taking only a few days from China
to Europe or North America.
