Surface Finishes for CNC Milling
There are a variety of surface finishes that can be achieved through CNC milling. The type of finish will depend on the material being milled, the desired appearance, and the tolerances required.
|Alodine||Alodine is a chemical used for metal surface treatment. It is most commonly used to create a protective coating on aluminum, but can also be used on other metals such as steel and brass.||Aluminum||Media Blasting, Tumbling, Type II Anodizing* Type III Anodizing*|
|Anodizing||Anodizing improves corrosion resistance and protects the metal surface. It's used in mechanical parts, aircraft, and automobile parts. Precision instruments also use anodizing for protection.||Aluminum||Media Blasting, Tumbling, Alodine*|
|Black Oxide||Black oxide is a specialized process that can be used to create a number of different finishes on metal surfaces. The most common use for black oxide is to create a blackened finish on steel, but it can also be used on other metals, including aluminum and brass.||Steel, Stainless Steel||Media Blasting, Tumbling, Passivation|
|Electroless Nickel Plating||Electroless nickel plating process is often used to improve the corrosion resistance or electrical conductivity of the metal, or to build up a thick enough layer to serve as a wear-resistant coating.||Aluminum, Steel, Stainless Steel||Media Blasting, Tumbling|
|Electropolishing||Electropolishing can be used to remove burrs, scratches, and other irregularities from the surface of a workpiece. The process can also be used to increase the surface area of a workpiece, which can improve its heat transfer or wettability properties.||Steel, Stainless Steel||-|
|Media Blasting||Media blasting is a process in which a high-pressure stream of media is used to clean or finishing surfaces. It is an effective way to remove paint, rust, and other debris from metal surfaces.||Aluminum, Steel, Stainless Steel, Brass, Bronze, Copper||All post processes except Electropolish and Powdercoat|
|Nickel Plating||Nickel plating is a process in which a layer of nickel is applied to the surface of another metal. The purpose of this process is to provide protection against corrosion and wear, as well as to give the metal a shiny appearance.||Aluminum, Steel, Stainless Steel||Media Blasting, Tumbling|
|Passivation||Passivation is the process of making a material more resistant to corrosion. It is accomplished by the formation of an oxide layer on the surface of the metal. This oxide layer prevents further oxidation of the metal, and it also provides a barrier to the diffusion of corrosive species into the metal.||Steel, Stainless Steel||Black Oxide, Electroless Nickel Plating, Zinc Plating, Tumbling, Media Blasting|
|Powder Coating||Powder coating is a dry powder that can be applied using electrostatic charge to create a smooth finish. Unlike liquid paints, powder coatings do not use solvents that work by evaporating the paint.||Aluminum, Steel, Stainless Steel||-|
|Tumbling||Tumbling is often used to deburr or remove sharp edges from metal parts. It can also be used to polish surfaces or add a decorative finish.||Aluminum, Steel, Stainless Steel, Brass, Bronze, Copper||All post processes except Electropolish and Powdercoat|
|Zinc Plating||Zinc plating is a process in which a thin layer of zinc is applied to a metal surface in order to protect it from corrosion. The zinc layer can be applied either by electroplating or hot-dip galvanizing.||Steel, Stainless Steel||Media Blasting, Tumbling, Passivation|
Precision Machining Tolerance
We follow ISO 2768 standards for CNC Machining.
|Limits for nominal size||Metals (ISO 2768- f)||Plastics (ISO 2768- m)|
|0.5mm* to 3mm||±0.05mm||±0.1mm|
|Over 3mm to 6mm||±0.05mm||±0.1mm|

Overview: What is CNC Milling?
CNC milling is a machining process that uses computer-controlled rotary cutters to remove material from a workpiece. The process can be used to create custom parts or prototypes from a variety of materials, including metal, plastic, and wood.
The Basics Of CNC Mills
Computer Numerical Control (CNC) milling is a specific form of machining that involves the use of computerized controls to operate factory tools and machinery. In CNC milling, programmable commands are fed into a machine that then uses those commands to cut or shape materials.
The first step in any CNC milling project is creating a computer model of the desired object. This model can be created using CAD software or a 3D scanner. Once the model is complete, it is converted into a set of instructions called G-code. This code tells the CNC machine what movements it needs to make in order to create the desired object.
Once the G-code has been generated, it is loaded into the CNC machine and the machining process begins. The machine will follow the instructions in the G-code, moving its cutting tools accordingly. The end result is a physical object that matches the original computer model.
How CNC Milling Works
CNC milling is a process where a machine uses computer-controlled cuts to remove material from a workpiece. The milling machine has a rotating cutting tool, and the computer controls the direction and depth of the cut.
Milling can be done with a variety of different tools, including end mills, ball nose mills, and routers.End mills are the most common type of milling cutter, and they are used to cut horizontal slots, vertical slots, or round holes. Ball nose mills are used to cut three-dimensional shapes. Routers are used to cut curved or irregular shapes.
The computer controls the milling machine by sending commands to an electronic control unit (ECU). The ECU interprets the commands and sends signals to servomotors that move the cutting tool in the desired direction. The servomotors also control the speed and depth of the cut.CNC milling is a very versatile manufacturing process. It can be used to create parts with complex shapes and geometry, and it can be done quickly and accurately.
Frequently Asked Questions
A CNC milling machine is a computer-controlled machine used for the machining of metals and plastics. The three main components of a CNC milling machine are the bed, the column, and the head. The bed is the horizontal surface on which the material to be machined is placed. The column is the vertical support that holds the head in place. The head contains the tools that perform the machining operation.
When it comes to CNC milling machines, there are a variety of materials that they can be used to process. Some of the most common materials include metals, plastics, and composites. Each material has its own unique set of characteristics that need to be considered when choosing the right CNC milling machine for the job.

A CNC milling machine is a computer-controlled device that can create complex 3D shapes from a variety of materials. Although these machines are versatile and powerful, they do have some limitations.
One limitation is the size of the object that can be created. A CNC milling machine typically has a work envelope that is only a few feet in size. This means that larger objects cannot be created using these machines.
Another limitation is the type of material that can be milled. Most CNC milling machines can only mill metals and plastics. This means that tougher materials, such as wood or titanium, cannot be milled using these machines.
