You may meet several problems like burring, gumming, delaminating and others when you shorten the carbon fiber tube. These problems are not unavoidable. Only if you do it accordingly to the basic tips, you should have a clean cut.
Here we collect the problems that usually occur when cutting carbon tubes. We will explain the reasons for these phenomena and the solutions. I hope it will be helpful to you all.
This problem is very common and there are 2 reasons to cause this issue. Did not choose the right blade and lack of support/securing of the tube. Or, choose the wrong blade.
Solution
1. Choose the right blade
Here we recommend not choosing a toothed blade. This is because the fibers can get stuck on the teeth while cutting. Metal blade cutting wheel also not a good choice. Although is very cheap, the blade is very easier to wear. need to change the blade often. The best tool is diamond coated cutting wheel.
2. hold the carbon fiber tube
before cutting, pls make sure the tube was secured with the clamps or holders on both ends. This prevents the tube from moving while cutting.
If the tube has burr, don't worry, you can use sand paper or other abrasive surfaces sand the tube cuts.
1. Too fast cutting speed leads to pipe delamination.
2. If the carbon fiber quality is bad also will make the carbon fiber tube delamination
3. If the temperature and pressure are not controlled (Insufficient temperature or overheating when the tube is formed), delamination may occur. It often occurs when cutting thicker-walled carbon fiber tubes
Solution
1. Slow down the speed when you cut the tube and don't let the blad force through the tube. Let the blade grind away the material slowly at its own speed. If this still does not solve this problem, you may need to change a thinner blade.
2. Choose the higher quality of carbon fibers are the less chance of delamination
3. Well control the temperature
This is often result of intense friction. The epoxy re-activate by the enough heat. The resin reaches its TG and begins to flow. Cause the blade to “gum-up” with resin
Solution
1. use liquid as a coolant to cool the blade and cutting surface
2. use segmented blade or wet saw
3. slow down the speed to reduce friction
When cutting the pipe, the pipe and the blade are not at 90 degrees or the tube didn't secure.
Only if you noticed these 2 points, the issue will be solved.
These are the problems that our customers often encounter.
