Making a CNC Rocker for Mountainbike from a billet. E7


I´m here at Jonathan Debus Fraestechnik that guy in the background is Jonny I know him since 2001 back in the days we where racing DH together. G: How old have you been that time? J: 13 or 14? He had a super cool self made bike frame with elastomer shocks. It was so cool. We know each other for so long and now it´s the first project we do together As I was looking for someone with talent to mill our rocker. And Jonny got talent ! So let´s try this Now we take this massive Aluminium block and mill out the rocker, let´s check it out! Here you see the simulation that´s what the mill is planing to do and what it will do very soon. [Klick] Klack, doing it with right torque! Let´s get started. Doors close! curtain on! Here you can the how the outer profile gets roughly milled. Soo, Jonathan is programing right now we are basicly in the process the part is already on the machine. and he is creating the program for the outer surface G: If that´s done we move to the next set up, right? J: Allmost, we just have to work on the thread and the bearing seats. And than we switch the machine Alright than let´s continue! Here you see you the mill emptys the pocket from both sides. On the left page you see the machine code. Now we just cut the thread which should be the final step of this set up. Than we can take the part out and move it to the next machine. Tadaaaaa BLING, BLING, BLING Now this side is done and we can take the part of the machine. on the next machine the massive amount on the bottom will be removed. Now let´s put it on the scale It weights in with 1206 gram Now we continue on this machine Already exited to put it on the scale once its all done. this is the set up for the second side I´m hanging here in the fork-lift truck and I´m waiting as the run time on the machine is enormous for this masterpiece of a rocker. Now it won´t take long anymore untill I receive the first finished part. And than we can put it on the scale and check the final weight. we are exited… The first finished rocker!! G: What do you think? J: Pretty Happy G Is it light? Put it on the scale… I just had this one on the scale with 1200 gram Now we are exited. Holy Moly Conclusion: From the Block [4500 gram] 3 Side milled [1206 gram] Final Product [259 gram] After a long day work the Rocker Number 1 is done. It´s very light, feeling stiff and fine. The production parts willget sandblasted for an even finish. Than there get anodized and mounted onto the bikes. well done Jonny You rocked it! If you have questions drop it in the comments ! And if you need Jonny just check his website and get in touch. http://www.debus-fraestechnik.de He got talent…
