Several of our lathes and mills (namely our G9729, G0602, G0752, G0704, and G0759) feature at least one gear made from polyoxymethylene (POM), a high-performance engineering thermoplastic. The use of POM gears is intentional and beneficial, as this material offers several key advantages over traditional metal gears in specific applications.
One of the primary benefits of using POM is noise reduction. Machines equipped with POM gears operate noticeably more quietly, which is especially valuable in smaller workshops or shared spaces. In addition to reducing overall noise levels, POM gears also help the machine run more smoothly and consistently, contributing to a better user experience.
POM is chosen for these components due to its high stiffness, low friction, and excellent dimensional stability. It resists wear, handles repeated mechanical stress well, and maintains its shape and performance over time—even in environments with varying temperature and humidity. These characteristics make it ideal for transmitting power while minimizing vibration and mechanical noise.
While some users might initially question the use of a plastic gear, it's important to understand that POM is not an ordinary plastic. It is a durable, high-precision material commonly used in demanding mechanical and automotive applications. Its inclusion in the drivetrain of lathes and mills reflects a modern approach to engineering that balances performance, longevity, and user comfort.
