What is CNC Milling?

CNC milling is an advanced process of removing material using specialized tools, which are programmed according to design drawings, develop tool paths, and move the cutting tool through multiple axes under computer control to gradually remove material from the workpiece and produce customized parts or products made of different materials, which can be processed by drilling, machining boring, face milling, milling grooves, tapping threads, and milling complex curved surfaces, etc.

Common Materials for CNC Milling

When selecting materials for CNC milling applications we usually consider the strength, wear resistance, weight and corrosion resistance required for the product and the cost of the material to select the material.

Plastic materials are easy to cut, light weight, corrosion resistance, applicability and other characteristics, but the composition of plastics and composite materials change a lot, so the milling process is easy to deformation and other characteristics, suitable for processing materials such as ABS, acrylic, PC, PVC, nylon, POM, PE, Teflon and so on.

Metal materials compared to plastic materials in terms of durability and strength and other advantages, therefore, the milling characteristics of tools used in processing metal requires higher cutting efficiency, long life, hardness and other characteristics of common metals, including aluminum, stainless steel, brass, copper, magnesium, titanium, zinc and so on.

Industrial Applications of CNC Milling

CNC milling should produce precision parts for a wide range of applications, common applications mainly include:

•Aerospace industry

Aerospace products have very stringent requirements for structural performance and quality.Considering the differences between aircraft construction and civil products, the required parts involve many new materials and designs, and advanced CNC technology plays a key role in the manufacture of aviation parts.

Robot parts have extremely high requirements for surface finish and precision, as robots need to overcome friction during movement.The high quality surface finish of CNC parts solves this friction problem, thus increasing robot life.

CNC Milling Tolerances and Surface Finishes

In CNC milling, we all need to enforce tight part tolerances and surface finishes to ensure consistent part quality and to avoid costly production errors and lead time delays.

Machining Tolerances: In practical machining, there is a tolerance range of values for both the machine and the process,at Kingsun, we will implement ISO 2768 standards for the production of parts, and we are able to control dimensions within ±0.125 millimeters, with tight tolerances of ±0.005 millimeters for critical dimensions.

Surface Finish Standards: Milling parts with visible and clear cutter marks on the surface, we can choose from a variety of surface finishes to enhance the functionality and aesthetics of the part. We can provide you with a surface finish that suits your needs. The most common surface finishes are Ra 1.6-0.8 μm.

What kind of surface treatment can make the milled parts more beautiful?

Machined milled parts usually have visible tooling patterns. To enhance functionality and aesthetics we have the option of sandblasting, polishing, anodizing, powder coating, plating and more.

What are the commonly used tools for milling?

The most common tools for milling processing are end mills, drills, ball cutters and fly cutters, etc. The materials are divided into white steel and tungsten carbide cutters, and different tools are selected according to different materials.
