Product details

Bakelite, as a high-performance insulation material, is widely used in industrial applications due to its excellent electrical resistance and thermal stability. CNC machining enables precise fabrication of Bakelite components, making it ideal for producing complex insulation material CNC machined parts with tight tolerances. The insulation material processing of Bakelite via CNC machining offers distinct advantages, including minimal material waste and high repeatability. Compared to traditional methods, insulation material CNC processing ensures smoother surface finishes and dimensional accuracy, critical for electrical and mechanical applications.

The Characteristics of CNC Machining Bakelite (Phenolic Board), in Plain Terms:

Brittle Yet Hard

Bakelite looks like plastic, but it’s surprisingly brittle during machining. Apply a little too much force, and it’ll chip or crack. But don’t be fooled—it’s also pretty hard. If your tool isn’t sharp enough, it’ll just "drag its feet," so you need tough tools and high spindle speeds.

Poor Heat Dissipation

Bakelite conducts heat about as well as a thick quilt. All the heat builds up on the cutting edge, and before you know it, you’ll smell burning. You’ve gotta blow air on it while machining to keep things cool.

Dust Everywhere

Instead of nice, curled chips, you get clouds of fine powder. Inhale it, and your lungs will hate you. Let it settle on the machine, and you risk electrical issues. A dust collector is a must.

Stable as a Rock

Once machined, it barely warps at all. Perfect for precision parts like circuit board spacers.

Soft When Handled Right

Despite its hardness, CNC cuts through it like butter—if you dial in the right settings. Feed too fast, and you get ragged edges; too slow, and you’ll burn the tool. Gotta find that "just right" sweet spot.

Cheap and Tough

Way cheaper than metal, so scrapping a part doesn’t hurt as much. Plus, it’s insulating, moisture-resistant, and a go-to for lab electrical fixtures.
