Custom Surface Treatment
AFI Industries Ltd. provides surface treatments for custom precision CNC parts. Whether you need anodizing, electroplating or surface treatment for other projects, our expertise adds value to your parts to meet the quality requirements of your products.
Anodizing: refers to the process of placing the metal in an appropriate electrolyte and forming an oxide film on the metal surface through the action of external current. This layer of oxide film has the characteristics of high hardness, high corrosion resistance and high insulation, which can protect the metal surface from environmental erosion, and improve the wear resistance and corrosion resistance of the metal.
Electroplating: A process that uses the principle of electrolysis to coat the surface of a metal or other material with a layer of metal or alloy. This process, through the action of electrolysis, makes the surface of metal or other materials attached with a layer of metal film, so as to prevent metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflective property, corrosion resistance and improve the appearance of the effect.
Spraying is a coating method by spraying gun or dish atomizer, with the help of pressure or centrifugal force, the paint is dispersed into uniform and fine droplets, which are applied on the surface of the coated object.
Brushed is a surface treatment method that forms lines on the surface of the workpiece by grinding the product to play a decorative effect. Because the surface drawing treatment can reflect the texture of metal materials, it has been loved by more and more users and more and more widely used.
Sandblasting is a process for surface treatment of workpieces. The compressed air is used as the power to form a high-speed jet beam to spray the spray material (copper ore, quartz sand, emery, iron sand, sea sand) to the surface of the workpiece to be treated at high speed, so that the appearance or shape of the workpiece surface is changed.
Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece in order to obtain a bright, flat surface processing method. Is the use of polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece.
Stainless steel is known for its corrosion resistance, making it the first choice for medical equipment and food processing equipment.

Frequent Asked Questions
Precision Grinding and milling are two different machining methods, and they mainly have the following differences:
1, processing principle
Grinding: Cutting the surface of the workpiece using a large number of abrasive particles on a high-speed rotating abrasive tool (such as a grinding wheel). Each abrasive particle is like a tiny cutting tool, which contacts the workpiece at a very high linear speed and removes the workpiece material through the cutting, scoring and sliding of the abrasive particle. The grinding process generates a lot of heat and requires the use of coolant for cooling.
Milling: Cutting the workpiece by means of the cutting edge on the rotating milling cutter. The rotary motion of the milling cutter and the linear or curved feed motion of the workpiece are combined to make the cutting edge continuously cut into and cut out the workpiece material, so as to realize the processing of the workpiece. The milling process also generates heat, but it is less than grinding and can generally be cooled by air cooling or a small amount of coolant.
2, processing accuracy
Grinding: Usually high machining accuracy can be achieved. The dimensional accuracy can reach IT5-IT7 level, and the surface roughness can be as low as Ra0.1-Ra0.8 microns or even smaller. Grinding can achieve very fine processing, suitable for parts with high precision requirements, such as precision bearings, optical components, etc.
Milling: Machining accuracy is lower than grinding. The dimensional accuracy is generally IT8-IT11, and the surface roughness is about Ra1.6-Ra6.3 microns. Milling is suitable for parts processing with general accuracy requirements, such as mechanical structures, molds, etc.
3, processing materials
Grinding: can process a variety of hardness materials, including high hardness hardened steel, carbide, etc., can also process softer materials such as aluminum, copper, etc. Grinding is an effective machining method for some difficult materials.
Milling: It is mainly suitable for processing metal materials with moderate hardness, and it is difficult to process high hardness materials. Milling can also process some non-metallic materials, but the processing effect and scope of application are relatively limited.
4, processing shape
Grinding: mainly used for processing plane, cylindrical surface, conical surface, inner hole and other shapes. For the processing of complex shapes, special shaped grinding wheels or multi-axis linkage grinding equipment are required. Grinding can achieve high-precision shape processing, such as high-precision spherical surface, aspherical surface and so on.
Milling: can process plane, surface, groove, thread and other shapes. Through different types of milling cutters and processing processes, complex shapes can be processed, such as mold cavities, complex mechanical parts, etc.
Processing efficiency
Grinding: The general processing efficiency is relatively low. Because grinding is a micro-cutting processing method, the speed of removing materials is relatively slow. At the same time, in order to ensure machining accuracy and surface quality, cutting parameters and multiple feeds need to be controlled during grinding, which will also affect processing efficiency.
Milling: The processing efficiency is relatively high. The cutting edge of the milling cutter is more, and multiple cutting points can be processed at the same time, and the speed of removing materials is faster. Moreover, milling can adopt advanced processing technology such as high-speed cutting to further improve processing efficiency.
