Important considerations when machining extruded POM sheets and rods

POM (polyoxymethylene) is a thermoplastic material that belongs to the family of engineering plastics. It is a popular choice for precision components in many industries due to its high stiffness, low friction, and excellent dimensional stability. In this blog post, we will discuss some important considerations when machining extruded POM sheets and rods.

POM extruded stock shape can be obtained in the form of rods or sheets, which can be further processed into different shapes and sizes. When it comes to precision machining of POM parts, here are some key factors to consider.

POM is a tough and durable material but is also susceptible to chip formation and burr formation during machining. Hence, it is important to choose the right machining parameters like cutting speed, feed rate, and depth of cut. Setting these parameters too high can cause the material to melt and smear rather than cut. On the other hand, setting them too low can lead to excessive heat buildup and poor surface finish.

To achieve precise and accurate POM machining, it is essential to use the right cutting tools. For instance, sharp carbide tools work well for machining POM due to their ability to withstand high wear and stress. It is also important to select the right geometry for the tool to ensure efficient chip evacuation and prevent tool wear.

Cooling and lubrication are critical factors when machining POM sheets and rods. During the machining process, heat buildup can result in thermal expansion, dimensional changes, and damage to the material's surface finish. Cooling and lubrication help to reduce heat buildup, and will also help to remove chips and contaminants from the cutting area. Using coolants or lubricants like oil or air is recommended to achieve effective cooling and lubrication.

Once machined, the POM sheets and rods should be properly fixtured to avoid any deformation or distortion of the material. Improper handling can lead to the weakening or breaking of the material, which in turn can compromise its performance. Therefore, when fixturing POM sheets and rods, it is important to take into account the shape, size, and orientation of the part to ensure the best possible result.

In conclusion, it is essential to pay attention to the various factors involved in precision machining of POM extruded sheets and rods. Choosing the right machining parameters, cutting tools, cooling and lubrication, and fixturing will help to ensure that the end product is of high quality, and performs according to specifications.
