Which end mill is best suited for cutting PCB boards?
The answer is :For cutting PCB boards (typically FR-4 fiberglass), the Corn Cob Router Bit is the most suitable choice. Some one call it diamond bit,
Why use a Corn Cob Bit?
Dust Control:
Grind the fiberglass into fine powder rather than long, sharp fibers by numerous tiny cutting edges
Burr Reduction:
This design effectively prevents delamination (layer peeling) and leaves a much fine cleaner edge.
Durability:
FR-4 is highly abrasive. These bits are usually made of good Tungsten Carbide, which offers the extreme hardness needed to withstand the wear.
What should you pay attention to when cutting a PCB board?
1.Safety goggles should be worn.
Safety goggles protect the eyes from flying shards when cutting or scratching materials. Fiberglass and other particles can cause serious eye irritation or injury, so goggles act as a barrier against accidental shards.
2.Gloves should be worn.
Gloves protect hands from cuts and sharp edges from glass or sheet metal. They also prevent contact with fiberglass particles, which can irritate or damage the skin
3.The PCB board should be secured in place.
The PCB board should be held in place using a vise or clamp to maintain its stability during operation. This stability helps achieve precise cutting and reduces the risk of injury or work errors due to slippage.
