5 Common Rapid CNC Machining Questions - Zintilon
Locating a CNC machine is relatively easy. However, finding the ideal CNC machine shop for your prototyping requirements could be difficult. A shop may have all of the capabilities you require, but that does not guarantee you can trust them with your parts. Capabilities alone are inadequate. The fact remains that who you work with is more important than what you can do.
How do you locate a CNC machine shop that can handle everything from materials to post-processing to production? When you find your desired CNC machine shop, ask these questions to be confident in their ability to be responsible for your parts.
What Materials Can Be Used?
In rapid CNC machining, various materials can be used to create precision parts. The choice of material depends on the project’s specific requirements, including factors such as durability, heat resistance, conductivity, and cost. Here are some common materials used in rapid CNC machining:
Metals
Here are the common metals used for rapid precision CNC machining:
- Titanium
Titanium alloys are renowned for having remarkable strength-to-weight ratios, allowing them to be robust and lightweight. They also have strong heat conductivity and resistance to corrosion. Furthermore, titanium is biocompatible, making it appropriate for biomedical applications.
However, using titanium has certain disadvantages. It is difficult to machine and has poor electrical conductivity. It is an expensive material to use in CNC manufacturing, and ordinary HSS or weaker carbide cutters are inappropriate for machining.
- Aluminum
As a very versatile metal, aluminum is considered very lightweight compared to many other metals. This feature is especially beneficial in sectors such as aerospace and automotive, where saving weight is very important for fuel economy and overall performance. In addition, aluminum has a high corrosion resistance because of the natural formation of a thin oxide layer on its surface. Its high thermal and electrical conductivity make it even more suitable for usage in heat sinks and electrical parts.
- Stainless Steel
Stainless steel is known for its strength, endurance, and rust resistance. Incorporating chromium in its structure gives it a protective shield that is resistant to rust and corrosion, making it suitable for use in environments where moisture and harsh conditions prevail. The increased tensile strength of stainless steel makes it very useful in many applications that require structural integrity, such as medical devices, kitchen appliances, automotive components, and parts used for building construction.
- Copper
The great thermal and electrical conductivity of copper is well known. However, because of its high malleability, it can be challenging to machine. This may make it harder to generate chips when using a CNC. Furthermore, copper is prone to corrosion, which may be problematic in some situations.
Despite these difficulties, copper is widely used in many industries, including electrical wiring, magnetic products, and jewellery making. Its aesthetic appeal and malleability make it a popular choice in the jewellery industry, and its high conductivity make it an ideal choice for electrical and electronic applications.
- Brass
Brass is known for its superior machinability, corrosion resistance, and aesthetic value. This metal is straightforward to machine, and the fact that it does not rust or tarnish ensures durability and the maintenance of appearance in the long run. The appearance of brass metal is very golden, which makes it one of the best decorative components. It has industrial use in many sectors, such as the production of door handles, ornaments, jewellery, electrical connectors, musical instruments and valve parts for plumbing and hydraulic systems.
- Magnesium
One metal that combines strength and light weight is magnesium. Due to its superior thermal characteristics, it is perfect for usage in engines and other high-temperature settings. Because of its lightweight, lighter and more fuel-efficient vehicles can be produced.
But in some applications, magnesium’s flammability also raises safety issues. In addition, it can be more expensive to machine and has a lower resistance to corrosion than some other metals, like aluminum.
Plastics and Composites
Here are the various plastics and composites used in rapid CNC machining:
- ABS
ABS plastic
ABS is a highly affordable plastic material that works well with CNC machining because of its superior impact and chemical, tensile, and machinability properties. It is also quickly coloured, which makes it perfect for applications where aesthetics are crucial.
Nevertheless, ABS is not biodegradable and should not be used in hot conditions. Additionally, burning it releases an offensive fume that could be problematic in a CNC shop.
- Acrylic (PMMA)
Acrylic is a material that is frequently used and has the potential to replace glass because of its favourable qualities. Because of its muscular rigidity and good optical clarity, it can be used in situations where see-through surfaces are required. Acrylic components are a visually pleasing and practical replacement for glass, possessing excellent optical clarity and a high level of durability.
Acrylic is still a common material for CNC machining despite certain drawbacks, such as its sensitivity to thermal softening and cracking. These drawbacks are offset by acrylic’s ease of use and versatility.

- Nylon
Exceptionally strong, hard, and resistant to impact, nylon is a material that can be used for many purposes. Its exceptional surface lubricating properties enable its use in a multitude of composite forms, including glass-fibre-reinforced nylon. On the other hand, using it in damp environments is not advised.
Applications requiring protection against frictional forces are especially well-suited for nylon. Sprockets, bearings, sliding surfaces, and gears are a few examples of these components. Numerous industrial and sports-related products are commonly made of nylon due to its exceptional strength and lubricating qualities.
- Polycarbonate (PC)
Due to its distinct set of qualities, polycarbonate (PC) is also a popular option. Its exceptional transparency makes it the perfect material for use in items that need to be clear, like electronic displays, medical equipment, and safety glasses. Additionally, it can be used in high-temperature applications due to its good heat resistance.
Unfortunately, its lack of UV resistance and scratchiness can make it unsuitable for use in some situations. It may become brittle and turn yellow after prolonged exposure to sunlight. Unless UV stabilisers are added, this may restrict its use in outdoor settings.
- Polypropylene (PP)
With its high chemical resistance and fatigue strength, polypropylene is a multipurpose polymer that offers many advantages. Furthermore, when machined, this medical-grade material yields a smooth surface finish. It is somewhat difficult to machine, though, because it softens and galls when cut, making it incapable of withstanding high temperatures.
For a variety of uses, PP is still a popular option. Gear and medical products can be made with it thanks to its exceptional qualities.
- Acetal (POM)
Acetal is a very adaptable plastic with a variety of desirable properties that is used in CNC machining. It has low friction coefficients, respectable toughness, and outstanding fatigue and impact resistance. Additionally, it has a high level of moisture resistance, which makes it a great option for use in damp environments.
Acetal’s stiffness, which makes it simple to machine with excellent dimensional accuracy, is one of its main advantages. Because of this, it is a well-liked option for use in precision parts like gears, valves, and bearings. Acetal is a dependable material for various industries, including consumer goods, automotive, and aerospace, because of its superior mechanical qualities and high resistance to environmental factors.
