What should be considered when CNC machining ultem?

When CNC machining ultem, attention should be paid to controlling the machining temperature and selecting the appropriate tools. Ultem material is sensitive to heat, so it's important to control the cutting speed and feed rate and choose the proper tools to ensure machining quality.
What are the main material properties of ultem ?

Ultem material has extremely high heat resistance (Can be used continuously at temperatures up to 170°C), excellent chemical resistance, corrosion resistance, and impact resistance. It also has good insulation and wear resistance.
Is it possible to vapor polish ultem?

Vapor polishing is a polishing technique specifically designed for transparent plastics like ultem and acrylics. It proves to be a superior option for applications requiring transparency, and it can effectively polish internal features such as threads and bores.
What are some common applications of ultem?

Ultem is often selected for parts requiring robust strength and stiffness, especially in high-temperature environments. Its applications are diverse, including but not limited to medical devices, electronics, and industrial equipment.
