Can you tap screw holes or dill thread holes on the carbon fiber tubes directly

Can you tap screw holes/ dill thread holes on the carbon fiber tubes directly?

Yes, Tap screw holes /drill holes on the carbon fiber tubes no problem. But we don't recomend drill hole on the carbon fiber tube directly . Why? The carbon fiber tube is made by carbon fiber laminated fabric, Once drill holes on the carbon fiber tube, it will cut off the carbon fiber, destroy the integrity of the laminate of the carbon fiber. If you NOT frequently disassembled the bolt from the hole, for example, disassembled 1 or 2 times. Drill screw holes on the carbon fiber tube no problem. If you frequently disassembled the bolt from the hole. We recomend install a metal screw sleeve on the carbon fiber tube directly. So that the bolt can connect the screw sleeve directly, It can disassembled many times. The video is tap screw holes on the carbon fiber tube directly.

The advantage for the  tape screw holes on the carbon fiber tube  :

1.Light weight,High strength, Carbon fiber is a good material which have 7 times strength than steel, It means same size, the carbon fiber robot arm can bearing more load, And carbon fiber is 1/5 weight of steel, It can reduce 4/5 of weight, So that can save more power when use the robot arm;

2. Good corrosion resistant, Carbon fiber robot arm can working at hostile environment,long service life, So that you no need spend much money to replace the arms;

3. Size can be customized,  Xinnuo can supply round, square, rectangular etc shape part .
