Frequently Asked Questions (FAQs)

Frequently Asked Questions About Machining Acetal in China

What are the key benefits of using POM (Delrin/Acetal) for CNC machining?

When you choose POM (Delrin/Acetal) for CNC machining, you gain several advantages. This material is highly resistant to wear and abrasion, has excellent dimensional stability, and exhibits low friction. It also has great chemical resistance and can maintain its shape well under various temperature and humidity conditions. These properties make it ideal for parts that require precision, such as gears, bearings, and other mechanical components.

What industries commonly use POM CNC machining services?

POM CNC machining services are widely used across several industries. You’ll find these services in the automotive sector for parts like gears and bearings, in aerospace for components requiring high precision and low friction, and in the medical field for devices that need to be chemically resistant and have high dimensional stability. Additionally, consumer goods and electrical industries also benefit from the unique properties of POM.

How is POM CNC machining performed?

To machine POM, you start by generating a CAD file of the part and converting it to CAM for G-code creation. The POM workpiece is then cut to size and securely fixed on the CNC machine to prevent movement during processing. Professional cutting tools, such as general-purpose flat end mills, are used to remove material from the workpiece. It’s crucial to ensure the workpiece is stable and to vacuum the CNC machine frequently to avoid debris buildup.

What surface finishes are available for POM CNC-machined parts?

For POM CNC-machined parts, several surface finishes can enhance the quality and appearance. You can opt for bead blasting to create a sleek matte surface, or use powder coating for a solvent-free finish in various colors and gloss levels. Other techniques like polishing or sandblasting can also be applied to improve the surface finish and aesthetic appeal of the machined parts.

How can I ensure cost efficiency in POM CNC machining?

To ensure cost efficiency in POM CNC machining, you should optimize the part design by reducing unnecessary features and tightening tolerances only where necessary. Using larger batch sizes can also help reduce costs by optimizing machine time and minimizing setup costs. Additionally, choosing a reputable and experienced CNC machining company can provide expertise in material selection, part design, and machining optimization, helping to reduce overall costs.
