How to burr free PCB
Sharp tools reduce burrs and monitoring tool life will help to minimize burrs. and produce consistent quality parts.
Sharp tools reduce burrs and for that reason. it is a good idea to use a different tool for finishing than the one used for roughing.
There is a lot of money to made by optimizing strategies and tooling selection. One of the more common culprits is the tool you are using. Always make sure your tools are sharp, since a dull tool can cause serious burrs even with the optimal tool path. In fact, watching for burrs is one of the best ways to monitor tool life. at least until you have a good understanding of how your go-to tools are going to perform. Also, this is one reason it’s a good idea to use a different tool for finishing than you do for roughing. that way you ensure the best finish and also limit burring.
Burrs when drilling can. avoided by drilling deep enough (through the material) to account. for the angled tip of the drill.
Burrs when drilling can occur because you haven’t drilled deep enough to account for the angled tip.
When it comes to drilling, many of the same rules apply. A dull drill is going to give you larger burrs on the bottom of your part . when you drill through – fresh drills will help with that. One of the simpler causes of burrs when drilling is not drilling deep enough. When you are drilling through your part you need to make sure you make up for the angled tip. the larger your drill diameter the deeper you will need to go. Drilling too shallow will result in what almost looks like a cap on the bottom of your part. not to mention a taper at the bottom of your hole. If you drill deep enough with a good, sharp drill you should be good to go.
Burr free drilling requires sharp tools and making sure you drill completely. through the material to account for the angled tool tip.
Burr free drilling can achieved by maintaining sharp tools. and accounting for the angled drill tip. when drilling through holes.
Burrs are a frustrating, time consuming problem that you will always deal with on some level. take care of your tools, mind your feeds and speeds and make sure you are drilling deep enough. It can be more efficient to utilize your CNC machine to deburr in process. keep in mind there will always be geometry that you will need to deburr by hand. Get next to it folks, cause it’s never going away. keep it under control. Until next time, be safe and mind the numbers.
