Material of CNC Machining Parts


Aluminum: It is common material for its excellent strength,lower cost and recyclability .It is commonly used for machining parts for gears,lock components,pipe fittings and so on.

Copper: It is a soft,malleable and ductile metal with thermal and electrical conductivity,which is suitable for machining the wire connectors and discharge electrode.

Tool Steel : It has wear resistance character and is used to machine the fixtures ,machinery components ,tools holders and so on.

Stainless Steel :The high resistant to corrosion and rust make it suitable for machining the components with longer use time.

Titanium Alloy :It can withstand high and subzero temperature for machining parts aerospace fasteners,engine components and so on.


ABS: It is a kind of material with lower cost used for injection parts ,then machining.     

Nylon:Resistance to frictional and chemical wear make it suitable for machining parts for medical devices and electronics insulation 

Acrylic  :It is common and resistant plastic material and used for tanks and other application.

PMMA:It is a kind of high transparency material and used for medical instruments and automobile industry.

 PEEK:PEEK material can be working in high-stress or high-temperature applications ,so it can replace some soft materials .

POM:It has higher hardness and resistance compared other plastic ,POM is suitable for machining parts of instruments components and wearing parts.

What is CNC Machining ?

CNC machining is a popular manufacturing process to make raw material into half-machined or final products, Workers use computer program software to input the instructions into the machine’s system. This process can be used in a wide range of complex types of machinery, such as CNC grinding, CNC milling, and CNC turning. With the help of CNC machining technology, Complex machining tasks can be finished in a single set of machines with precision and high velocity.

How Does CNC Machining Works

The programs are usually automatically created by CAM software for the CNC machining process, The computer generates the code for the 3-D model and gives the direction to systems with tools and workpiece material. This code controls the movements of the workpiece and the tools, also the code can give the direction to turn on or off the coolant and other machinery components.

CNC machining can be used for a wide range of materials, such as aluminum, brass, ABS, and PMMA. Whatever the soft or hard material, they all can be CNC machined. It plays an important role in the manufacturing industry.

The Differences of CNC Engraving and High Speed Milling Machines

The working speed and feeding speed of a High-speed milling machine is faster than normal CNC machines, the spindle speed can reach 30000RPM, and the processing speed and reaction speed is obviously superior to other CNC machines with lower speed.So we can use a high-speed turning process with micro-end mills to enhance the productivity and parts’ accuracy.Meanwhile, the deformation of the part is greatly reduced because of less force when milling and turning

In summary, the high-speed milling machine is suitable for machining high-precision parts, brass material, graphite electrodes,s and so on. In the process of molding parts, high-speed milling machines are used to machine the tool steel with 60HRC which greatly reduces the working time of Wire E.D.M.

CNC engraving is a collective name for engraving, carving, and molding. The spindle speed can reach over 30000RPM, but the spindle power is less than the CNC machine center. This CNC engraving machine is suitable for machining small parts with higher accuracy requirements. There’s less advantage during the heavy cutting process, and the whole machine is smaller than CNC high-speed milling machine. Since CNC engraving is mainly used to machine small parts, such as the electrode machining, aluminum parts, and molding industry. The whole machine is smaller than CNC high-speed milling machine.
