What is CNC milling ?
CNC milling is a kind of technology based on CNC tool machine, through programming to control the motion track and cutting process of the milling tool, to achieve high-precision milling of the workpiece. CNC milling has the characteristics of high precision, high efficiency and high degree of automation, and is widely used in mold manufacturing, precision parts processing, aerospace and other fields.
Materials of CNC milling
CNC milling is mainly used for cutting metal materials. It can cut all kinds of metal materials and some non-metallic materials, such as steel, iron, copper, aluminum, stainless steel, titanium alloy, plastic, bakelite, wood, etc., and can realize the processing of different shapes and angles of materials.

Surface Treatment of CNC milling
-
Anodizing
Anodizing is a process that oxidizes the metal surface to form a dense, hard oxide layer, which is usually used for the surface treatment of aluminum alloy, magnesium alloy, titanium alloy and other metal materials.
Its functions include:
- Enhance the hardness and wear resistance of the metal surface
- improve the mechanical strength and corrosion resistance of the metal material
- Form a uniform oxide layer, protect the metal surface from external oxidation, corrosion
- Improve the beauty and decoration of metal surface
-
Bead Blasting
Bead Blasting for steel, titanium and aluminum, often used in tactical folding knives and straight shank knives, are characterized by 100% dull tool surfaces and complete elimination of reflections.
-
Powder Coating
Powder coating is the use of powder equipment to spray powder coating to the surface of the workpiece, under the action of static electricity, the powder will be uniformly adsorbed on the surface of the workpiece, forming a powdery coating; The powder coating is cured by high temperature baking and leveling, and becomes the final coating with different effects (different kinds of effects of powder coatings). Its advantages are high efficiency, less pollution, high utilization rate of paint and good film performance.
-
Electroplating
Electroplating is a process in which a layer of metal or alloy is plated on the surface of a metal or other material using the principle of electrolysis. It is a metal coating on the substrate, so as to change the surface properties or dimensions of the substrate, in order to improve wear resistance, corrosion resistance, electrical conductivity, reflective, wear resistance, improve beauty and so on.
-
Polishing
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.
-
Brushing
Brushing is a surface treatment method that forms lines on the surface of the workpiece by grinding the product to play a decorative effect.
Tolerances of CNC milling
CNC milling use high-precision machine tool numerical control system, with high machining accuracy and repeated positioning accuracy, it can meet the high-precision machining requirements of the workpiece.
| Linear dimension | +/- 0.025 mm +/- 0.001 inch |
|---|---|
| Hole diameters (not reamed) | +/- 0.025 mm +/- 0.001 inch |
| Shaft diameters | +/- 0.025 mm +/- 0.001 inch |
| Part size limit | 950 * 550 * 480 mm |
Advantages Of CNC milling
-
Strong adaptability and flexibility of parts processing
It can process the contour shape is particularly complex or difficult to control the size of the parts, such as mold parts, shell parts, etc.
-
High processing precision, stable and reliable processing quality
The pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1um, in addition, numerical control machining also avoids the operator's operation error.
-
High degree of production automation
It can reduce the labor intensity of the operator and is conducive to the automation of production management.
-
High production rate
The CNC milling machine only needs to call the machining program stored in the CNC device, the clamping tool and the adjustment tool data when replacing the workpiece, thus greatly shortening the production cycle. Secondly, the CNC milling machine has the functions of milling machine, boring machine and drilling machine, which makes the process highly concentrated and greatly improves the production efficiency.
Conclusions
CNC milling has a very wide range of applications, can cut a variety of metal and non-metallic materials, and can complete a variety of complex shapes of parts and workpieces.
- Check the machine power and stiffness to ensure that the milling cutter diameter used is as short as possible in the overhang of the tool used in the machine
- The number of teeth of the milling cutter is moderate to ensure that there are not too many blades and the workpiece at the same time during processing and cause vibration.
- Suitable feed per tooth to achieve good cutting results when the chips are thick enough to reduce tool wear.
