CNC Machining Materials
These are low-carbon metal alloys that shows good mechanical properties, machinability and weldability at a reasonable price. It can also be carburized to increase the hardness. Common grades are: Q235, Q345, 1020, 1045, etc.
Other alloying elements together with carbon forms Alloy steels. They are associated in improving hardness, toughness, fatigue and wear resistance. Common grades are: 40Cr, 4140 (42CrMo), 4340, etc.
Stainless steel alloys offers high strength, ductility, wear and corrosion resistance. You can easily weld, polish, or machine them.
Common stainless steel cnc machining grades are: 304, 310, 316, 17-4ph, 2205, etc.
Aluminum alloys show good strength-to-weight ratio, possessing high thermal and electrical conductivity, natural corrosion resistance, low density and it can easily be anodized.
Common aluminum cnc machining alloys are: 6061, 6063, 6082, 7075, etc.
Brass & copper are basically metal alloys that offers good machinability and excellent electrical and thermal conductivity. They can ideally be used in places where low friction material is required. It’s often used for bus bars, wire connectors, and other electrical applications. Examples of alloys are: C36000, C10100, C11000, etc.
Surface Finishing Options
As-machined
When the CNC machining process is finished, it can creat a smooth surface finish with minimum roughness Ra6.3. The parts will keep as machined surface when there is no additional surface finish requirement. CNC machining can also produce a part with higher surface finishes such as Ra3.2 or Ra1.6.
Powder Coated
This is a process where CNC machined parts are sprayed with powdered paint and then baked in an oven under a certain temperature. Compared to painting process, powder coated finish is more durable, as the surface layer of cnc machined parts are strong, wear- and corrosion-resistant. A variety of colors can be chosen to achieve a decorative effect.
Anodized
Anodizing is one of the most durable finishes that prevents cnc machined parts from scratching. This type of surface finish is only suitable for machined aluminum parts. Like power coating, a wide variety of colors are available to create the desired appearance.
Zinc Plated
Zinc plating, as known as galvanization, applys a thin coat of zinc to the surface of cnc machined steel parts by electrical current. After forming a protective layer of zinc oxide, cnc machined parts will not rust when exposed to air or water.
Applications of CNC Machining
Aerospace Industry
CNC machining was first used in Aerospace. It is used in this industry because it offers lightweight parts with exceptional physical properties and high tolerances. CNC machining can be used for aircraft parts as well as during the development stages.
Automotive Industry
CNC machining is also beneficial in the automotive industry during the production of high-performance custom parts. CNC machining is usually used in the production of key components.
Electronic Industry
The electrical and electronic manufacturing industry also prefers CNC machining in various processes, such as CNC machining, to manufacture parts for high-power electronic sensing systems.
Defense Industry
The military sector also uses CNC machining to prototype rugged and reliable parts. The machining intends to allow the parts to withstand wear and tear with minimal upkeep.
Robort & Automation
Robotics and automation industry mainly uses CNC machining for fabricating robotic end effectors, custom jigs and features, and storage units. Since CNC machines can hold the tolerances of ±0.05 mm and surface roughness of Ra 0.8μm, the designers can achieve dimensional accuracy for robotic parts.
Oil & Gas Industry
The oil and gas industry also requires tight tolerances for the safety-critical application of CNC lathe. This sector uses CNC milling machines for the production of precise, reliable parts such as cylinders, pistons, rods, pins, and valves.

CNC Milling vs. CNC Turning
CNC Milling and CNC turning are all the machining processes in CFS Machine Shop. Although they look similar, are actually two kinds of different manufacturing processes, and suit for different shapes of machined parts. Understanding the differences between CNC milling and CNC turning will help to choose which one is suitable for your project, which saves both time and money.
What is CNC Turning?
CNC Turning Definition CNC turning, a short for Computer Numerical Control Turning, is a modern automatic CNC machining process to creat cylindrical components by removing material from a workpiece. It uses a computer control system to precisely control the movement of cutting tool, and shape out the desired dimensions in a high effecient way. For the advantage of flexibility, CNC
What is CNC Milling?
CNC milling, a typical CNC machining type, produces custom designed part by removing materials under computerized controls and rotating multi-point cutting tools. It is an ideal machining process to creat custom parts in different shapes. The available CNC milling materials could be metal, plastic, glass and wood. The CNC milling process begins with a CAD model, and the CAM soltware

Overview: What is CNC Machining?
CNC (Computure Numerical Control) machining is CNC machine tool processing, is equipped with digital control system of automated machine tools. It is a combination of machinery, automation, computers, and other high-tech new technology. Its basic components are digital control program carrier, machine tool device, drive spindle device, machine tool body, and safety guards.
CNC machining is controlled according to the programmed programming, usually G-code, to make the machine tool machining. The G-code digital language can control the machining process of CNC machine tools. It makes the tool control system use different position coordinates, control the tool feed and spindle speed, coolant and other functions.
The correctness of the toolpath can be analyzed using the CNC machine’s idle run. When the digital program is entered into the machine, the fixture tool and workpiece are installed. When the idle button is pressed, the spindle does not rotate and the table automatically runs along the programmed path. At this step, it is found out if there is any contact between the tool and the workpiece or the fixture. The above operation control is controlled by the cam, die and dividing device in the form of analog quantities. The machining accuracy of the parts is affected by the accuracy of the cams and dies, and it can process complex parts with certain flexibility and versatility and long process preparation time. CNC machining solves the problem of complex and precise, small batch and multi-species machining, and it is widely used in modern industry, which greatly improves the production efficiency of companies.
