What are the non-metallic materials suitable for CNC high-precision machining?

The non-metallic materials suitable for CNC high-precision machining mainly include the following:

Plastic materials such as ABS, nylon, polycarbonate, polyoxymethylene, etc. have good processing performance and high precision retention, making them suitable for CNC high-precision machining.

Composite materials, such as carbon fiber reinforced plastics, glass fiber reinforced plastics, etc., have high strength, low density, and good corrosion resistance, making them suitable for manufacturing lightweight and high-strength parts.

Engineering ceramics: Some engineering ceramics such as alumina ceramics, silicon nitride ceramics, etc., although difficult to process, can also achieve high-precision CNC machining by selecting appropriate cutting tools and processing parameters.

Artificial stone: such as artificial marble, artificial quartz, etc., these materials can also exhibit good processing performance and accuracy in CNC machining.

Rubber and elastomers: Certain types of rubber and elastomer materials, such as silicone, polyurethane, etc., can also achieve high-precision shape and size requirements through CNC machining.

Attention: When CNC high-precision machining non-metallic materials, it is necessary to select appropriate tool materials, machining parameters, and process routes based on the characteristics of the material and machining requirements to ensure machining quality and efficiency.

-How to remove burrs on plastic products made by machining centers?

This depends on your requirements for burrs and the processing method. There are several methods for deburring:
1. Adding a brush made of hard plastic on the CNC machining center can remove burrs inside the hole, generally ensuring that the burrs are less than 0.05mm;
2. Vibration grinding and shot blasting can be processed in this way if the requirements are not high;
3. For very small burrs, they can be removed by ultrasonic cleaning;
4. I once visited a project where tiny burrs were burned and removed through instantaneous discharge
