Why Choose Our Aluminum Cnc Machining Service

Here are the introductions to different types of metal finishes

Anodizing: Usually refers to the process of forming a layer of oxide film on aluminum products, in order to overcome the defects of aluminum alloy surface hardness and wear resistance. Many colors(such as black, red,blue etc.)are available. Divided into Type II (normal) and Type III (hard), Type III is usually thicker than Type II and more corrosion resistant.

Bead Blasted
Bead Blasted: A surface treatment process to obtain a certain degree of cleanliness and different roughness on the surface of the workpiece. The surface after sandblasting is dull and matt.

Powder coat
The plastic powder is adsorbed to the surface of the workpiece by electrostatic spraying to form a powdery coating, and then the powder layer is cured by heating and baking to level it into a uniform film layer.It usually used for appearance parts and a variety of colors are available.


  • Galvanizing: Mainly to make the surface more beautiful and rust free.
  • Chrome plating:It can make the metal products more durable. Hard chrome plating is mainly applied for machinery which under high temperature conditions, such as molds. Decorative chrome plating is mainly to make the surface brighter and more beautiful in appearance.
  • Nickel plating: It is deposited on the metal surface by oxidation-reduction effect, which is used to improve corrosion resistance and wear resistance, and increase beauty and glossy.
  • Titanium plating: preventing pollution, and will not cause allergic reactions in contact with the human body. Because the titanium compound has a variety of colors, it can increase the aesthetic effect. Meanwhile, titanium has the function of anti-acid, anti-alkali and anti-oxidation.
  • Silver plating: There are two main functions, one is decoration and the other is functionality. Decorative silver plating are used for oxidation resistance experiments. Functionality is mainly used in the electronics industry, such as electrodes, wires, electric shocks, pole pieces, and so on.
  • Gold Plating: is a method of depositing a thin layer of gold on the surface of another metal (most commonly copper or silver) through chemical or electrochemical plating.


  • Passivating: In physical chemistry and engineering, it refers to coating materials to make them “passive”, that is, not susceptible to environmental influences or corrosion
  • Electrophoresis painting:is a process in which metal parts are immersed in a water-based solution, and the parts are painted by passing electric current through the plating solution.
  • Chromate Conversion Coating(alodine coating) :converts the surface properties of the substrate (typically aluminum or magnesium) as compared to plating which applies a coating onto the surface of the substrate
  • Polishing is the finishing process of reduction of surface roughness to create a bright and smooth surface by mechanical, chemical or electrochemical action. It uses polishing tools and abrasive particles or other polishing material to enhance the visual appeal of the workpiece.
  • Metal heat treatment is one of the important processes in mechanical manufacturing. By comparison with other treatment processes, heat treatment generally does not change the shape and the chemical composition of the whole workpiece, whereas it improves the performance of the workpiece by changing the internal microstructure or the surface’s chemical composition.
  • Without any surface treatment processing methods, the parts will leave visible tool marks and burrs, which can be completed quickly and cost-saving.

Aluminum Cnc Machining Surface Finishes

Compared to basic CNC machining services, precision aluminum machining manufacture parts to a much more exact standard. Tolerances as small as ±0.0001” with right machines.In CNC machining, our standard tolerance for aluminum is DIN-2768-1-f.

The tolerance is greatly influenced by part’s geometry and material type. For the specific tolerance details of different parts, please contact us.

How can you control the cost of your machined parts?

CNC machining cost is mainly made of machining time, start-up cost, material cost and feature cost. In order to control cost, these factors will help you to some extent.

A design of fast machined features is the best way to reduce machining time. You could design by using correct inner radii, reducing cavity depth, increasing wall thickness, limiting thread length and choosing standard-sized holes and so forth.

Start-up cost can drop through reducing the number of part rotations or repositioning during machining. For instance, you could split the geometry into several parts to assemble them together.

Material cost reduction needs to consider the size of the required stock and both the cost and the machinability of big material. Soft alloys can be generally machined faster.

Feature cost control can consider using tolerances as necessary only, avoiding logo machining and multiple surface treatments.

For more details, please see the full guide of cost reduction about CNC machined parts.

How is the quality of your parts guaranteed?

At BE-CU, we treat your order seriously and attach great importance to the quality.

To ensure high-quality parts, any suppliers can not go into our manufacturing network except for the verified ones.
