The CNC machining process, standing for computer numerical control machining, is a subtractive
manufacturing approach that utilizes a synergy of computerized controls and machine tools to
eliminate layers from a solid block of material. Programming dictates the desired cuts in the metal,
aligning them with specific tools and machinery, and the automated process executes the machining
task accordingly.

FAQ's
1. What are the minimum and maximum dimensions you can machine?
Our comprehensive CNC machining services cover milling (3-axis, 3+2-axis, and 5-axis) and
turning processes.
In 3/3+2-axis CNC milling, we can achieve part dimensions up to 2000 x 1500 x 200 mm
(78.7 x 59.0 x 7.8 in.). For 5-axis milling, the maximum part size is 650 x 650 x 300 mm
(25.5 x 25.5 x 11.8 in.). CNC turning accommodates a maximum diameter of 431 mm (17 in.)
and a length of 990 mm (39 in.).
Smaller parts are recommended to have dimensions around 10 x 10 x 10 mm
(0.39 x 0.39 x 0.39 in.), with a minimum feature size of 0.5 mm. It's important to be aware that
our platform imposes a maximum part size of 1000 mm (39 in.), and for larger requirements,
we encourage you to contact our sales team for tailored support.
2. How much do CNC machining materials cost?
The multitude of materials available for CNC machining introduces a range of costs, influenced by
the unique properties and characteristics of each material. In the realm of metal parts,
Aluminum 6061 is a standout for its economical pricing. If cost efficiency is a priority, ABS takes
the lead as the most budget-friendly option.
Importantly, the ease of machining is a key factor impacting costs. Stainless steel, known for its
hardness in comparison to aluminum, presents higher machining complexities, contributing to an
overall increase in costs.
3. Can passivate my parts?
Passivation is a treatment designed to change the surface chemistry of select metals.
We offer passivation services to provide corrosion protection, improve durability, enhance aesthetics,
and more.
4. What are you shipping terms?
Our standard shipping terms, applicable to both rapid prototyping and regular production orders,
are Ex Works (EXW). Under these terms, the customer assumes responsibility for shipping, customs
clearance, and all associated fees once the goods have left our premises.
For express shipments, we follow the Delivered Duty Unpaid (DDU) model, placing the onus on the
client to pay import duty upon the goods reaching their destination.
