CNC machining black pom parts high smooth surface

Why always have a bad surface for some factory ? not smotth .

Because  they only rough cnc machining the surface , and no precision milling it . maybe this is why always have a very lower price in China . because they delete lot of cnc work .

For AIXI hardware , we will always precision milling the products surface , smooth surface , looks better . thats why so many customers satisfied us .
