More Materials For CNC Machining Components
As the development of the CNC machining, more and more materials are used in the CNC machining. People have many choices on the materials, from aluminum to copper, from plastic to wood. It is a good advantage of CNC machining that the number of materials that can be used with them, providing owners with multiple options. The most common materials we are used now are metal, plastic, wood, and so on. So let’s talk about one by one, and welcome visit our material sheet guide too.
Metal Material for CNC Machining Components
Now, most parts are made of metal. It is used widely as accessories for all kinds of machines. Especially its precision and short lead time make people prefer to do with it. Different metal has a different characteristic. Among them, aluminum is easiest to work with. It is extremely durable, can be recycled, and is easy to cut through. But sometimes, the customer has special requirements on the material, such as thickness or toughness, we have to check whether the aluminum can meet the requirement, or we need to change to steel, even brass or bronze, which is really not easy to produce on the machine. What’s more, metal has a very distinct and shiny appearance, so when we make the metal projects, we should pay attention to appear clean and sharp. That’s why the labor cost for the metal part is higher than the others.
The common metal material such as:
- Aluminum 6061T6, 6063T6, 6028T6, 7075T6.
- Stainless Steel: 304, 303, 316/316L.
- Steel Alloy – Gray (Steel Alloy 4140)/ Steel Mild Low Carbon – Gray (Steel Mild Low Carbon CR1018).
- Brass – Yellow (Brass C360)/Copper.
Plastic Materials for CNC Machining
Plastic is also used by many people too. Easy to work, lightweight, and low cost is preferred by customers. If a part can be done both by metal and plastic, obviously, plastic is the best choice, since it is much cheaper. There are also many kinds of plastic. PVC is one of them. PVC which stands for polyvinyl chloride is a plastic that is easy to work with CNC machines. It is cut through by CNC machines and with a smooth finish. Another good point for plastic is it comes in a variety of color options without extra paint. It gives designers lots of ideas about developing new products. Another commonly used plastic is plastic acrylic sheets. It has lots of different colors too and varies of thickness. If customers want to signs, storage boxes, protection shell, or something else, this material is the best.
The common plastics material: ABS, PP, Nylon, POM-C, PEEK, PFTE, PC, etc.
Wood is commonly seen in our daily life. It has a long history. When CNC machines come out, the wood continues to move forward on its development. Different from the traditional process, the CNC machine makes the wood easier to work with. Due to its non-recyclable, most of them are used for decoration or something similar. Also, the wood is easy to bent due to the humidity, though it is a popular material preferred by people, it is not an easy material to work with.
The common wood materials: Walnut, Oak Wood, Rose Wood, and Bamboo, etc.
CNC machines can work with various of materials. It depends on customers which material they prefer. Different materials can meet different requirements. Customers can choose the material according to the designer’s idea, the function, and the cost, and so on.
