Frameworks Bottom Bracket Main Pivot CNC'd on a 5 Axis | Downhill Bike Build 5DEV and Neko Mulally

We CNC Neko Mulally's Main Pivot / Bottom Bracket on his Frameworks Downhill Bike on a 5 Axis CNC Machine.
From a 12 Foot Bar of 6061 Aluminum to a bottom bracket / main pivot. Watch 5DEV cut Neko's frame pieces on a 5 Axis Doosan 5000 with 5th Axis Workholding. The frame parts will be shipped to Frank the Welder to complete the frame build.
5th Axis Workholding: V562X Self-Centering Vise and the RL96A-411 RockLock Riser

I was surprised to see you cutting from a bar in the beginning. It seems like every time I price out material it's cheaper to get it cut to size out of a plate rather than buy a bar and cut the bar up myself. And it saves the step of sawing and I can get it cut closer to the size I need than typical bar sizes.

Stoked to get an opportunity to race one of these! Incredible work guys 🔥💪🏼💯

[@ICON.Engineering_]

Great job, will there be a second op's video?

[@rustysena2638]

Nice work! What CAM software are you using? Also, did you chop off the dovetails in the next Op?

[@5DEV]

We do have a final Op not shown here.

[@Mike-lt6sj]

Judging by the finished product, they are using Fusion, and are new to 5x and machining in general. Nothing wrong with that, either. To get to where they are takes a lot of investment and dedication.

[@rustysena2638]

I think you might be mistaken about them being new to 5x. I'm guessing these parts are prototypes and don't need to have perfect surface finishes. 5 Dev are not new to 5x. I believe these are the same guys behind the company "5th Axis" work holding. @@Mike-lt6sj

[@kornphlake79]

That’s not how you use a torque wrench.

[@sofpreptraining8163]

LOL that's how you use a torque wrench when you wrench every day and know what you are doing.

[@jonlightfoot6739]

Nice part, shame about the surface finish though.

[@ICON.Engineering_]

I'm sure that it goes through polishing and glass bead blasting before anodizing

[@dutrajordan78]

What software was used for programming?

[@dasanoneia4730]

would loved to see yall cnc a whole frame in youre design language it could rival the P-Train ... just sayin

[@michaeltrilck5680]

At 2‘25“: PLEASE, Mr. Operator!!! Please do NOT tighten further After the „click“(if the torque wrench was set correctly)!!! You will shear the material(6061???7075???) in / at(?) the clamping area/ zone. You may also provoke subsequent cracking in the material structure! Be careful, please!!! Have a nice day!

[@antn8387]

mmmm forged billet aluminum.

[@dustinwalden7091]

Extruded billet aluminum

[@Mike-lt6sj]

Mmmm, it's just an extrusion. The extrusions parent was a billet. Usually, these terms are abused by Motorsports marketing teams. Now there's hipsters with machine tools making expensive 5x parts. For a bicycle, no less.

[@mgreenl24550]

Someone please give that guy some safety glasses. Oh, and a refresher on torque wrenches….

[@LoamMTBSlide]

Kids writing checks his ego can't cash.

[@Tezza120]

That did make me laugh. I mean to be fair it's at least X Newton-Meters so it shouldn't fly out of the vice but not good practice

[@crukdkersed8434]

Easier to call the game than to play it.

[@SixGunTodd]

Glasses for what ? Its a CNC shop....I've worked in plenty without safety glass requirements. Also of note we use junk torque wrenches in machines all the time....really no point in getting coolant in your precision toruqe wrench.

[@wings808]

No porting afterward?

[@Chainsnsprockets402]

No wonder bikes are so expensive!

[@5DEV]

HAHA! This is for a custom designed World Cup Race Bike. These aren't mass production parts.

[@irish-simon]

surface finish is so shit and that machine can do so much better we wouldn't let stuff like that out of your shop and not a hope it would end up online
