3.Choose the right tools
Material: Durable materials such as carbide or diamond coatings should be selected to cope with the abrasiveness of epoxy boards.
Geometry: The tool geometry should be suitable for cutting epoxy resin to avoid excessive wear and heat buildup.
Size: Choose the appropriate size according to the thickness and complexity of the project. In Epoxy board CNC Machining, the selection of tool size needs to consider multiple factors.

5、Technical points of Epoxy board CNC Machining

1.Tool path planning
Accurate planning is the key to achieving the desired shape and size, and CAM software can be used to generate efficient tool paths. Tool path planning is an important technical link in epoxy board CNC machining.

2.Feed rate and spindle speed
The best settings need to be found to prevent tool breakage and achieve good surface finish, which may need to be determined experimentally.

3.Application of coolant
Coolant helps dissipate heat, reduce friction and increase tool life. During the machining process, the appropriate coolant should be selected according to the actual situation.

4.Finishing
Depending on the application, post-processing processes such as frosting or polishing may be required to achieve the required surface finish. In the finishing stage of epoxy board CNC machining, appropriate process methods need to be used to improve surface quality.

6、Precautions for Epoxy board CNC Machining

CNC machining has certain hazards and requires certain safety guidelines to be followed.

1.Personal protective equipment
