FAQ of CNC Machining

What is CNC Machining?

CNC Machining is the use of CNC machines such as CNC mill or CNC turn to process metals or plastics to obtain high precision parts. The parts produced by CNC machining are very accurate and repeatable.

What are the common types of CNC machining service?

CNC machining generally refers to high precision CNC machining. Common precision CNC machining methods include CNC milling, CNC turning, 5 axis machining, Swiss turning, EDM, WEDM, grinding etc.

How much does CNC machining cost?

The cost of CNC machining mainly depends on the complexity of product structure and tolerance requirements. A more complex custom CNC machining product request higher accuracy and higher the price. Accordingly, more product demanding means a more economical price.

What kind of surface treatment can CNC machined parts do?

There are many kinds of surface treatments for CNC machined parts such as anodizing, coating, polishing, bead blasting, blacken, plating etc. However, the surface treatments on each material are limited. For example, CNC machined aluminum parts are most suitable for anodizing, while steel parts are suitable for polishing or heat treatment.
