The as-machined parts have the tightest tolerances, and because no post-machining is required, you can save a lot of surface treatment costs.
What is As Machined Surface?
As-machined surface refers to the original appearance of parts processed after CNC machining. This surface shows the real appearance of the part, and the tolerances will not be affected in any way.
Why Choose The Machined Surface?
The surface of the part formed after CNC machining is completed will have clear processing lines, and the surface roughness value is Ra0.2-Ra3.2. There are usually surface treatments such as deburring and sharp edge removal. This surface is suitable for all materials. In addition, this surface ensures that the accuracy of the part is not affected and saves a lot of secondary processing costs.
Polishing refers to a surface treatment method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of parts to obtain a bright and smooth surface.
Sandblasting is a surface treatment method that uses the impact of high-speed sand flow to clean and roughen the surface of the workpiece to obtain a certain degree of cleanliness and roughness.
Anodizing is a surface treatment method that uses electrochemical oxidation of metal or alloy to form an oxide film on the surface of parts, which can prevent wear and oxidation of parts and increase the aesthetic effect. Different colors can be achieved on the part surface. This surface treatment is only suitable for metal parts.
Galvanizing is a surface treatment method of plating a thin layer of zinc on the metal surface, which can prevent metal oxidation, improve wear resistance, corrosion resistance and enhance aesthetics. The surface of the parts can also be plated with copper, nickel, silver or gold. This surface treatment is only suitable for metal parts.
