2022-05-16 15:26:57

When it comes to machining, CNC is one of the most commonly preferred types of machining methods because of its high precision and accuracy. On top of that, CNC pom machining is gaining popularity as a machining method because it requires less tooling and manpower, compared to conventional machining methods. Moreover, CNC pom machining equipment uses smaller workpieces which allows for high production rates. This can be helpful for any company that needs small batches of complex parts for short-run production. CNC pom machines are also very common in companies that have a variety of large and small components to create using different materials. They are perfect for many tasks such as drilling holes in pockets, adding threads, milling press fits, tapping holes in plastic materials, EDM work, and so on.

I work for a custom design and manufacturing service for over 12 years. One of our strongest points is CNC machining, and since I work in that industry, I would like to appear in this blog for the purpose of sharing with others the advantages of CNC pom machining

 

Pom Machining

What is Pom?

POM is a thermoplastic polyoxymethylene resin. It is a form of polyacetal. The acronym POM stands for polyoxymethylene or polyacetal. It is a transparent, hard plastic with low friction, low wear, and excellent chemical resistance. POM has good electrical properties and can be molded into filaments and fibers. POM has the lowest coefficient of friction of any engineering plastic. In addition, it has less creep in the presence of solvents than nylon 66 or acetal (Delrin) which makes it an ideal material for precision bearings and gears. The use of POM as a replacement for metal bearings in appliances like portable fans has had some success. POM can be machined on any lathe with carbide tools using conventional turning techniques.

 

What is Pom Machining?

Pom machining is a process that has been in use for decades. It involves the use of a computer-controlled tool to create parts from a solid block of metal. It is also called CNC machining, which stands for computer numerical control. This process is also known as CAM, which stands for computer-aided manufacturing.

Pom machining is often used for short-run, high-volume production of small, simple parts. It can be used to machine large volumes of parts but isn’t ideal for long runs because there is no way to remove chips from between tools.

Pom machining works with both hard and soft materials, including ceramics, plastics, and metals. It requires minimal setup, so it is well suited for low-volume production runs where it is not practical to set up conventional CNC machines.

In addition to its ease of use, pom machining offers some distinct advantages over conventional CNC machining:

Less expensive than conventional CNC milling

Higher speeds than conventional CNC milling

Lower tool costs than conventional CNC milling

What Are the Most Common Applications for Pom Machining?

The most common application of POM is in the medical industry as bone implants because it has good wear resistance, strength, and stiffness.

Medical Devices - Medical device makers use polymers like polycarbonate, PEEK, and PEI to create molds for their products. These materials are ideal for medical devices because they can be sterilized and won't corrode or react with other substances that come into contact with them during surgery.

Electronics - The electronics industry relies on plastic parts for many of its products, including phones, computers, and televisions. These parts are often made with Nylon 6 or Ultem®, which can withstand temperature changes and extreme environments without breaking down over time.

Another common application for pom machining is in the automotive industry, where it’s used to make high-performance engine valves and other parts that require wear resistance and strength at high temperatures. It’s also used in consumer electronics, sports equipment, and even musical instruments such as guitars and violins.

 

What Are the Benefits of Pom Machining Instead of an Injection Molded Part?

Professional Answers to Your Questions About Pom Machining Versus Injection Molding

Injection molding is a popular way to mass-produce parts. But it has its limitations. Take pom machining for example. This process offers some benefits over injection molding, including:

Lower cost of production. Since pom machining is less expensive than injection molding, the parts produced with this method are cheaper to produce.

More flexibility in design and part characteristics. With pom machining, you can create unique shapes and sizes that would be difficult or impossible with injection molding.

Smaller tooling costs. When using pom machining, you don't need to create molds for every part you want to manufacture because these tools are reusable. Injection molding requires making new molds each time a new part is required, which can be quite expensive and time-consuming if you have several similar parts that require different specifications (such as color or size).

 

Does Pom Machining Conduct Electricity?

The manufacturing and machining of poms are done through CNC and manual machining. The material can be aluminum, brass, or steel. In the process of machining, electricity is conducted through the machine and this can cause injury to the machinist.

Pom Machining Machine Safety

Safety is the key priority when operating any type of machine. When machining poms, there are a few things you need to keep in mind to avoid accidents:

Make sure that all electrical equipment at your workstation is turned off before working with the tooling or parts. This includes routers and grinders.

Make sure that your power tools have been properly grounded by following the manufacturer’s instructions, especially if they have been rewired or modified by a third party.

Always wear protective headgear when operating any power tool. This includes goggles, safety glasses, face shields, or helmets with earmuffs/earplugs when working with routers and grinders.

 

Is Pom Machining Recyclable?

The answer is yes, poms are recyclable!

Pom machining is the process of forming a polymer into a specific shape. It's done by adding heat and pressure to the material. The result is a strong, durable piece that can be used in manufacturing processes.

Recycling poms is simple: they're made up of recyclable materials like metal, plastic, and rubber. All you have to do is separate them from other materials and send them off to be recycled!

 

What Are the Typical Sizes of Parts That Can Be Made Using Pom Machining?

The pom is a versatile part that can be made in various sizes and configurations. The smallest parts tend to be around 0.5" in diameter, but it is possible to make them as large as 4" or 5".

The most common sizes are 2", 3", and 4". While it is possible to make smaller poms, there is not much demand for them, so it may not be worth the time and effort required to produce them.

If you want to make parts larger than 5", then you will need a different type of machine tool called a lathe. Lathes are used for metal turning, which means they can turn around an axis that runs through the center of the part being machined.

Poms can also be made in different cross-section shapes such as round, square or rectangular shapes. This is accomplished by using different milling cutters on your machine tool to create the desired shape after each pass of material has been removed by cutting off small chips or shaving off small amounts of material until your design has been fully formed

Can CNC Pom Machining Be Welded?

Here are some of the most frequently asked questions about CNC pom machining:

Does it require welding?

It depends on what type of work you want to do. If you want to machine a single piece and then weld it, then yes. But if you are looking for a full assembly, then no.

Can I use standard tools?

Yes, with some minor modifications. The key is to make sure that your tooling is compatible with the material being used for the pom machining project.

What about tolerances?

The tolerances for CNC machining are typically +/- 0.025mm or +/- 0.005 inches (0.1mm or 0.02 inches).

 

How Are the Machines for Pom Machining Operated?

The machines for pom machining are operated in a number of ways, depending on the type of machine being used. The most common way is to use an electric motor, but there are also manual and hydraulic methods.

Electric Motor: Electric motors are commonly used to power machines for pom machining because they have a high torque rating. They can be found in both AC and DC versions, which makes them capable of performing many different tasks with ease.

Manual Operation: Manual operations are often preferred by hobbyists who want to save money and still get a high-quality machine for their needs. This type of operation is typically less expensive than other types of operation, but it does mean that you will need to spend more time operating your equipment yourself.

Hydraulic Operation: Hydraulic operations are typically only used by professionals who have a lot of experience with machinery or who work in factories where they need to run machines 24 hours a day, seven days a week. These types of operations require very little maintenance work compared to manual operations because they do not rely on human error as much as other machines do.

 

What Arrangement of Teeth is Used on Cutters for Pom Machining?

The arrangement of teeth is important when it comes to pom machining. There are many different tooth arrangements, but the most common ones used in this type of manufacturing are:

1. Straight cutters - The cutter is shaped like an arbor or pinion and is used on straight shank tool holders. The cutting edges are straight and parallel to the axis of rotation. The cutter has a single-sided rake angle and a double-sided clearance angle. This arrangement gives you the best control over chatter because it allows for a greater feed rate than other arrangements. It also has good chip control, which results in smoother finishes and less surface roughness on your part.

2. Spiral point & face cutters - These cutters have a spiral point that helps reduce vibration as well as create chips that are more easily cleared from the workpiece by their shape and size than other designs do for this type of machine tool process. They also have a positive rake angle that helps produce cleaner cuts with less chipping on softer materials like aluminum alloys and plastics such as ABS, polycarbonate, acrylics, PVCs, or urethanes because they're harder than steel or titanium alloys that would be machined with standard straight shank tool holders.

 

How to Choose the Best Plastic Material for CNC Machining Process?

The best plastic material for the CNC machining process is one that can be machined easily and with minimal distortion, while still being able to withstand the stresses of the process.

A good example is POM (polyoxymethylene), which is a thermoplastic that has good dimensional stability and thermal properties, as well as excellent wear resistance. It also has a high resistance to many chemicals, making it ideal for medical applications.

POM is commonly used in gearboxes and other parts that need to be tough and durable.

Another good example is nylon 6-6, which is another thermoplastic that can be machined easily with minimal distortion due to its high impact strength combined with low density. It also has excellent electrical insulation properties, making it suitable for use in electronics products such as smartphone cases.

Nylon 6-6 has been used by Apple Inc., which uses it to make iPhone cases from its own custom-designed material called Liquidmetal (aka Liquid Glass).

 

What Are the Advantages of CNC Pom Machining?
