How to CNC Machining POM (Delrin/Acetal) ?

Advantages and considerations of POM machining

POM (polyoxymethylene) is an important engineering plastic, widely used in automotive, electronics, machinery and other fields, is one of the indispensable materials for modern industrial manufacturing. POM machining, on the other hand, is the process of manufacturing this material into a variety of complex plastic products through a variety of machining processes.

First, the advantages of POM machining mainly include the following aspects:

1, High processing precision:

The use of high-speed CNC machine tools for processing, can achieve sub-millimeter level error range, but also to ensure that the surface finish and texture of the product.

2, High efficiency:

Compared with the traditional processing methods, it has a higher processing efficiency, greatly reducing the processing cycle and improving productivity.

3, Low cost:

The use of digital control technology, can achieve high efficiency, intelligent production, thus reducing production costs.

Because of this, POM machining is widely used in the manufacture of various high-precision parts. For example, in the automotive field, POM materials have been widely used in the manufacture of engine injectors, sensors, water pump impellers and other high-precision parts, which can greatly improve the performance and reliability of the car.

Second, POM machining considerations

In addition to POM machining technology itself, there are a number of technologies related to it is also worth paying attention to. For example, in the design and development of POM materials in the process, the need to use CAD / CAM software for simulation and analysis and manufacturing planning; in the POM material mold manufacturing, it is necessary to use three-dimensional printing and other advanced technologies, so that the accuracy and quality of the mold has been improved.

In addition, environmental protection is also an important factor we need to consider. Although the POM material has excellent physical and chemical properties, but its production process of waste water, exhaust and other pollutants also have a certain impact on the environment. Therefore, we need to take scientific and reasonable measures to reduce the pollution emissions during the production and processing of POM materials and protect the environment.

In summary, POM machining, as a high-precision processing technology, plays an increasingly important role in modern manufacturing. Its wide application in automotive, electronics, medical devices and other fields can not only improve the performance and stability of products, but also promote the innovation and development of the whole industry. But at the same time, we also need to pay attention to environmental issues, take effective measures to reduce pollution emissions and achieve sustainable development.

POM machining related technology and process flow

POM, polyoxymethylene, is a high-performance plastic, which is widely used in automotive, electrical appliances, instruments, medical equipment, mechanical equipment, sports equipment and other industries because of its high strength, high hardness, good abrasion resistance, chemical stability, good insulation and other excellent properties.POM machining is the process of machining POM blanks into parts and components or finished products to meet the requirements.

POM machine processing can be used in traditional machining, injection molding, extrusion, blow molding and other processes. Among them, machining is one of the commonly used processing methods.POM machining is mainly divided into turning, milling, drilling, cutting, grinding and other operations. In the machining process, attention should be paid to the selection of suitable machine tools and cutting tools to ensure the quality and efficiency of processing.

Before POM machining, it is necessary to pre-treat the POM material blank. First of all, the POM material blanks placed in constant temperature and humidity conditions of natural cooling, so that its internal stress is released. Second, the POM blanks are dried to remove moisture and internal stresses. Then, the POM material blank for cutting, grinding and other processing to ensure that the surface is smooth, flat, in order to facilitate the subsequent machining operations.

During POM processing, some common problems should be noted. First of all, POM material is easy to stick to the knife, so you should choose the right tool, and clean the tool in time. Secondly, POM material is easy to produce burrs, burrs and other problems, in the processing should pay attention to the cutting direction of the tool and the choice of cutting parameters to ensure that the processing surface is smooth. In addition, POM material is also relatively brittle, prone to warping, cracking and other problems, in the processing should pay special attention to the positioning and clamping of the machine tool.

POM machine also has many processing application skills. For example, in turning and milling, should start processing from the outer circle, and gradually move to the inside, in order to reduce the processing pressure, to avoid deformation. When drilling, repeated entry and exit of the orifice should be avoided as much as possible to minimize the irregularity of the hole. When grinding, soft cotton cloth and other auxiliary tools should be used to avoid excessive grinding, affecting the processing quality.

In short, POM machining is an efficient, high-precision, high-quality process that has a wide range of applications in various fields such as industrial manufacturing. Therefore, when carrying out machining work, it is necessary to fully understand its related technology and process flow in order to give full play to its excellent mechanical and chemical properties.
