burr free drilling Aluminium entry material advantages
Achieve burr-free finished holes, without predrilling. or stepdrilling – Faster and more accurate than twist drilling!
Benefits of the CS Unitec Cutter Design:
Precision-ground flutes provide efficient chip clearance, increasing drilling productivity and decreasing cutter breakage.
Double-action tooth geometry cuts, splits and ejects chips more ,
increasing cutting speed
reducing tooth load
minimizing tool wear
lengthening cutter life
Engineered with a tapered inner wall for smooth, easy slug ejection.
Center hole for pilot pin aligns the cutter. allows for internal lubrication and removes the slug.
Perfect drilling to close tolerances without runout. The result: a burr-free finished hole.
Burr's patented BurrFree drill offers you a more efficient drilling process. by combining two independent machining operations into one. This specialty combination tool. connects an Allied T-A spade drill insert to the arbor of the carbide series tool. and offers you the perfect one-step burr free drill. It drills a hole and then deburrs both the front and back of the hole in one operation. That efficiency, plus the tool’s exceptional quality, durability. and utility translates into meaningful savings.
Available from Ø9.5mm with a variety of lengths to suit applications.
1. sheet aluminium can protect the circuit board against scrapes and pressing marks.
2. Aluminium drilling entry board enhances the dimensional accuracy. exit board creates the drilling have assistance to ensure that the drill functions without deflection.
3. Alu pcb entry sheet significantly lengthens the life span of the drill bit. Its particular alloy composition will keep the cleanness and the cooling of the drill little bit. Whats more, aluminium board pcb really is an excellent conductor of warmth so it helps prevent overheating of the drill little bit and it can prevent the oxidation of the top.

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.
