POM (Acetal)

POM is an acronym for polyoxymethylene. It is a thermoplastic discovered in the 1930s by German engineers.

First, it is semi-crystalline, meaning it has both crystalline and amorphous regions. The crystalline regions give POM strength and rigidity, while the amorphous regions give flexibility and toughness.

Seond, it is also chemically resistant and has a low coefficient of friction. For these reasons, POM is often used in CNC machining. When machining POM, it is essential to use high speeds and coolant, as this will help to prevent melting and chipping.

ABS (Acrylonitrile Butadiene Styrene)

There are many reasons why ABS is well-suited for CNC machining.

First, its strength and durability make it ideal for creating parts that will withstand major wear and tear.

Second, its smooth surface finish gives it a professional look and feel.

Third, its easy machinability means that it can be quickly and easily processed without requiring special expertise or expensive equipment.

Nylon is a versatile plastic used in various applications, including CNC machining.

There are several reasons why nylon is well-suited for CNC machining.

First, nylon is strong and durable, making it ideal for nylon parts that will be subject to wear and tear.

Second, nylon is resistant to heat and chemicals, making it an ideal material for harsh environments.

Third, nylon is easy to machine and has a low friction coefficient, making it ideal for high-speed applications.

PC (Polycarbonate)

Polycarbonate is a strong, durable plastic that can be used in various applications. One of the most common uses for polycarbonate is in CNC machining.

First, polycarbonate is an ideal material for CNC machining because it can be easily cut and shaped into various shapes and sizes.

Second, it is a very strong material that can withstand high temperatures and pressures.

Third, it is clear and can be used to create translucent or see-through products.

PTFE (Teflon)

PTFE is a versatile plastic used in various applications, including PTFE CNC machining. Its unique properties make it ideal for this purpose.

First, PTFE is highly resistant to wear and tear, meaning it can withstand the high speeds and pressures associated with CNC machining.

Second, PTFE is chemically inert and won’t react with the machined materials. This makes it an ideal choice for applications where precision is required.

Third, PTFE is self-lubricating, meaning it doesn’t require using cool or other lubricants during machining. This makes achieving a high precision level easier and helps reduce the overall production cost.

PEEK (Polyether ether ketone)

Polyether ether ketone (PEEK) is a high-performance plastic with unique properties.

First, PEEK is often used in applications where strength and machinability are required because it is strong and stiff like metal, while it can also be machined and molded like traditional plastics.

Second, PEEK is frequently used to create parts with complex shapes and tight tolerances.

Third, it can be easily machined to acceptable tolerances without needing special cooling or lubrication.

Finally, it holds up well to repeated machining and can be polished to a high shine. We can machine PEEK parts.

CNC Turning: Its Definition, Machines, And Operations

CNC Plastic Machining Operations

Plastic CNC Milling

Plastic CNC milling is a process that uses a computer-controlled milling machine to remove material from a workpiece. The milling machine moves the cutting tool in specific patterns to remove material from the workpiece. This process can create parts with complex shapes and features.

Plastic CNC Turning

The cutting tool is mounted on a spindle and is fed into the workpiece as it rotates. The speed and depth of the cut can be controlled to produce the desired shape. CNC turning is an efficient way to produce complex shapes with a high degree of accuracy. The process can create both small and large parts, and can produce parts with a wide range of shapes and sizes.

Plastic CNC Machining: Surface Finishes


Sandblasting is a process that uses high-pressure air to shoot sand at a surface. This method can be suitable for many different materials, including plastic.

When sandblasting plastic, the coarse particles of sand remove the top layer of the material, revealing a new layer beneath. This process can create a rough surface that is ideal for painting or bonding.

Powder Coat

Powder coating is a type of paint that comes in a dry powder form. It forms a strong and durable bond when applied to a plastic surface.It provides even more coverage than traditional liquid paint, making it an ideal choice for plastic surfaces.

Vapor Polishing

Vapor polishing is a process used to improve the surface finish of plastics. The process involves using a hot, wet vapor to melt away small imperfections on the surface of the plastic. This gives the plastic a smoother, shinier finish.

The process removes small scratches and stains from plastic surfaces. Vapor polishing is an effective way to improve the appearance of plastics without damaging the material.

Plastic CNC Machining: Advantages

Easy and Fast To Machining

The use of plastic in CNC machining is becoming increasingly popular due to the many advantages it offers. Perhaps the most significant advantage is the speed with which prototypes can be produced.

Plastic is much easier to machine than metal, so that prototypes can be produced much more quickly. This is a major benefit for companies who need to get their products quickly.


Using plastic in CNC machining is a cost-effective way to create prototypes and production parts. In many cases, it is more affordable than metals and offers a wide range of physical and mechanical properties that make it ideal for many applications.

Good Chemical Properties

CNC machining is resistant to corrosion and chemicals. Metals are prone to corrosion when exposed to certain chemicals, but plastics are not. This makes them ideal for applications where chemicals are present.

Plastics are also resistant to much other damage that can occur to metals, such as scratches, dents, and discoloration.

Plastic CNC Machining: Applications

Medical Devices

CNC machining is commonly used in the medical device industry to create small, precise, and intricate parts. CNC-machined plastic parts are often suitable for implants, prosthetics, and surgical instruments. CNC machining provides a cost-effective way to produce small quantities of medical device components with tight tolerances

Automotive Components

There are so many types of plastics in the automotive industry.

As the automotive industry continues to evolve, so does the technology used to develop and manufacture components.

In recent years, plastic CNC Machining has emerged as a popular choice for developing everything from door panels to dashboards.

Plastic is lightweight yet strong, making it ideal for use in cars. Also, Plastic can be molded into any desired shape, meaning CNC machining has great flexibility when creating automotive components.

Aerospace Components

And plastic is ideal for aerospace parts because it is strong yet lightweight and can withstand harsh chemicals and high temperatures. Thus, plastic are often used to produce aircraft brakes, fuel lines, and nose cones.

Semiconductor Components

Semiconductor components are the foundation of modern electronics, and CNC plastic machining is a key technology used in their manufacture. The combination of precision and complexity makes CNC machining ideal for semiconductor manufacturing.

Many semiconductor components would be impossible to produce without CNC technology. As semiconductor components continue shrinking, CNC machining will become increasingly important. With its ability to create tiny, precise features, CNC machining will help make ever smaller and more advanced semiconductor components possible.
