POM is similar to acrylic because of its inherent optical transparency and crystallinity.
Delrin comes in a variety of textures, colors and grades.
POM CNC machining is essential for high volume production and runs efficiently.
It has a lower heat absorption rate compared to other grade polymers such as nylon and polyethylene.
Evolved into CNC POM prototyping, CNC machining plays a key role in prototyping.
Delrine or POM is also known as metallic plastic or super steel because of its high rigidity and strength.
POM can be efficiently milling, drilling, grooving and cutting with CNC machining.
Manufacturers can use it for a variety of applications such as aerospace, automotive and consumer goods.
Design engineers can benefit from its dimensional stability and achieve tighter tolerances of ±0.0005 inches.
Rapid prototyping with CNC machining is feasible.

It describes low-cost solutions and offers economic benefits when produced in large volumes.
POM is a common technique; For example; CNC machining, injection molding, and 3D printing.
Prototypes and complex geometric shapes are easier to manufacture with POM CNC machining.
POM numerical control machining method
Plastic CNC machining can be deployed through various technologies; For example; CNC milling, CNC drilling, lathes, grinding, blanking and punching. Its ease of processing greatly affects its use in these processes. In addition, it has also received a lot of attention for its high elongation. Now, let's discuss the method to get the best results POM CNC machining.
The process begins with computer-aided design and programming to improve accuracy, quality, and optimization levels. After the virtual configuration, the instructions are forwarded to the CNC machine in the following form: G code for further processing prospects.
A cutting operation is then performed on the workpiece material (POM) to obtain the optimal dimensions and dimensions. It is recommended to use coolant when machining Delrin at high speed to prevent ineffective processing operations such as chip buildup or overheating.
The following are some of the techniques commonly used to process strong polyformaldehyde or POM.
1.POM CNC milling
CNC milling is often used to machine POM parts. Tools with sharp edges help to get the best Angle, as well as surface finish. Therefore, it is reasonable to use a single slot milling cutter to process Delrin. These cutters prevent chip buildup during machining operations.
2.POM CNC drilling
Standard twist and center drills are best suited for processing polyformaldehyde resins. These materials have strong, sharpened edges that ultimately allow for smooth milling operations on Delrin. The optimal cutting speed of the drilled POM must be approximately 1500rpm and the lip torsion Angle 118°.
3.POM CNC turning
POM CNC turning operation is similar to brass turning operation. The best results can be achieved by maintaining high speed turning at the same rate as the medium feed rate. In order to prevent interference and excessive chip accumulation problems, a chip-breaker must be used for precision turning operations.
4. Blanking and punching
Blanking and stamping, both methods are preferred for small and medium-sized complex parts. During operation, cracks in the sheet can lead to major problems of improper processing. To eliminate this problem, it is best to preheat the Delrin plate and use a manual or high punch.
Highlights: "During POM CNC machining, it is important to keep the POM tight or hold the POM and use a hard steel or carbide tool.
List of Delrin grades for CNC machining
The two most common acetal grades are very useful for CNC machining; Polyformaldehyde resin 150, polyformaldehyde resin; 100 (AF). Let's evaluate their compatibility;
1. Delrin 150
Derlin 150 belongs to the acetal homopolymer family. It has high mechanical strength, stiffness and wear resistance. Thanks to these unique features, it is ideal for CNC machining of gears, bushings, gaskets and automotive interior and exterior finishes. In addition, its stability under high temperature conditions makes it ideal for irrigation and conveyor parts.
2. Delrin 100(A)
Delrin 100 A is integrated with polytetrafluoroethylene (PTFE) for enhanced mechanical stability and viscosity. It is widely used in gear systems or components that require low friction characteristics. In addition, it has strong moisture and chemical resistance. In addition, it eliminates the self-lubricating (oil or grease) characteristic, making it different from other Delrin grades.
Surface treatment options for POM
The desired surface finish plays a key role in the machining process. When it comes to surface treatment, two options are usually employed: machining and sandblasting. Here is a brief introduction to these;
After processing
CNC machining often leaves a bumpy surface or texture on the surface of the acetal part. When rough or textured parts are needed to improve the frictional properties of the parts, the surface treatment is preferred. The typical roughness range that can be achieved by machining is about 32 to 250 microinches (0.8 to 6.3 microns).
Pearl burst
In most cases, machining tools leave marks on acetal parts. Sandblasting is often used to prevent tool marks and enhance the visual effect of Delrin machined parts. It works by releasing glass beads or fine particles onto the surface of machined parts under high pressure. In addition, it improves durability and provides a valuable, smooth, matte, aesthetically pleasing and satin-polished appearance to polyformaldehyde resin machine parts.
There are other techniques; For example; Anodizing, polishing, painting and stamping. However, most design engineers prefer the above two options due to economic feasibility.
What are the limitations of Delrin CNC machining?
However, there are huge benefits to using Delrin for CNC machining. Besides, it also has some disadvantages. Here are Delrin's limitations;
Adhesion: Although acetal has excellent chemical resistance, it often presents challenges in bonding with strong adhesives. To overcome this problem, designers may need to employ post-treated surface options for best results.
Thermal sensitivity: Thermal sensitivity is a noteworthy issue for design manufacturers. The ability of acetone alcohols to withstand high temperature conditions is very significant. However, it is well suited for applications where mechanical stability is critical. But in some cases, when it is exposed to high temperature conditions, there will be deformation or distortion problems. Compared with nylon, nylon shows higher strength and structural strength even in harsh environments.
High flammability: The processing of polyformaldehyde resin faces the challenge of flammability. It is sensitive to temperatures above 121 degrees Celsius. It is recommended to always use a coolant, such as air coolant, to maintain the temperature during the processing operation. In order to overcome or control flammability problems, it is also necessary to use A Class A fire extinguisher when processing POM.
Delrin NC machining applications
From automotive interiors to aerospace components, Drin is used in a wide range of applications. Let's take a look at some of its key applications in manufacturing;

The two most common acetal grades are very useful for CNC machining; Polyformaldehyde resin 150, polyformaldehyde resin; 100 (AF). Let's evaluate their compatibility;
1. Delrin 150
Derlin 150 belongs to the acetal homopolymer family. It has high mechanical strength, stiffness and wear resistance. Thanks to these unique features, it is ideal for CNC machining of gears, bushings, gaskets and automotive interior and exterior finishes. In addition, its stability under high temperature conditions makes it ideal for irrigation and conveyor parts.
2. Delrin 100(A)
Delrin 100 A is integrated with polytetrafluoroethylene (PTFE) for enhanced mechanical stability and viscosity. It is widely used in gear systems or components that require low friction characteristics. In addition, it has strong moisture and chemical resistance. In addition, it eliminates the self-lubricating (oil or grease) characteristic, making it different from other Delrin grades.
Surface treatment options for POM
The desired surface finish plays a key role in the machining process. When it comes to surface treatment, two options are usually employed: machining and sandblasting. Here is a brief introduction to these;
After processing
CNC machining often leaves a bumpy surface or texture on the surface of the acetal part. When rough or textured parts are needed to improve the frictional properties of the parts, the surface treatment is preferred. The typical roughness range that can be achieved by machining is about 32 to 250 microinches (0.8 to 6.3 microns).
Pearl burst
In most cases, machining tools leave marks on acetal parts. Sandblasting is often used to prevent tool marks and enhance the visual effect of Delrin machined parts. It works by releasing glass beads or fine particles onto the surface of machined parts under high pressure. In addition, it improves durability and provides a valuable, smooth, matte, aesthetically pleasing and satin-polished appearance to polyformaldehyde resin machine parts.
There are other techniques; For example; Anodizing, polishing, painting and stamping. However, most design engineers prefer the above two options due to economic feasibility.
What are the limitations of Delrin CNC machining?
However, there are huge benefits to using Delrin for CNC machining. Besides, it also has some disadvantages. Here are Delrin's limitations;
Adhesion: Although acetal has excellent chemical resistance, it often presents challenges in bonding with strong adhesives. To overcome this problem, designers may need to employ post-treated surface options for best results.
Thermal sensitivity: Thermal sensitivity is a noteworthy issue for design manufacturers. The ability of acetone alcohols to withstand high temperature conditions is very significant. However, it is well suited for applications where mechanical stability is critical. But in some cases, when it is exposed to high temperature conditions, there will be deformation or distortion problems. Compared with nylon, nylon shows higher strength and structural strength even in harsh environments.
High flammability: The processing of polyformaldehyde resin faces the challenge of flammability. It is sensitive to temperatures above 121 degrees Celsius. It is recommended to always use a coolant, such as air coolant, to maintain the temperature during the processing operation. In order to overcome or control flammability problems, it is also necessary to use A Class A fire extinguisher when processing POM.
Delrin NC machining applications
From automotive interiors to aerospace components, Drin is used in a wide range of applications. Let's take a look at some of its key applications in manufacturing;
Medical industry
POM is an important material for medical components or equipment. As an engineered thermoplastic, it meets the strict quality standards of the FDA or ISO. Its applications range from enclosures and housings to complex functional components; For example; Disposable syringes, surgical tools, valves, inhalers, prosthetics and medical implants.
Automobile industry
Derlin supplies a wide range of automotive components to the automotive industry. Its high mechanical strength, low friction, and wear resistance allow engineers to use it to make important car, motorcycle, and electric vehicle parts. Some common examples include: articulated housings, locking systems, and fuel transmitter units.
Consumer appliances
When it comes to convenient applications, polyformaldehyde processing describes several significant benefits. Manufacturing experts use it to make zippers, cooking utensils, washing machines and clips.
Industrial machinery parts
Derlin's great strength enables it to be used in industrial parts manufacturing. Its ability to withstand wear and low friction characteristics makes it ideal for components such as springs, fan wheels, gears, housings, scrapers and rollers.
