#30 Aluminium CNC Plates #30 / Water-Jet Cut, Intermediate Plate and Sizing Holes

- In this video I bite the bullet so to speak, getting a set of plates cut in aluminium. All the work from the previous videos has culminated in a design I feel confident to commit to metal, and to a method (water jet) which I had to get done externally.

Waterjet cutters look like they rammed the job through as quickly as possible. Been interesting to see a perfectionist like Grimsmo bring so much of that sort of stuff in-house where he can control the output.
Good video series, keep it up.
Yep - Perfectionists are hard to come by these days. Even I feel like I have to rush sometimes. Cheers.
Those linear rails sounds crunchy
I'd personally loosen the upper rail, fix the bearing blocks and use the gantry plate itself to set the distance between them... Moving it along and tightening the rail down. Should guarantee parallelism.
Also: That error in your water jet is where the operator selected outside in instead of inside out on that part of the svg/dxf file by mistake
That's exactly the alignment method I wanted to suggest also, give it a try. Good luck!
That's right.
That's looking solid, it's going to be awesome. Bit late for me to sudjest this, but have you thought about having a double gantry, with the rails either side and the spindle between. When the spindle is trying to ram an end mill in the material, it's going to tram/nod the z axis a certain amount, much less if supported front and back. Then all there is to worry about is the backlash on the z lead screw letting the cutting forces bounce the spindle up and down. Great work. Glad to see your stliton this project.
Cheers Sirus, I had thought about putting a third rail on the back and making a triangle to the top of the z axis to triangulate. But I was worried it might interfere with the drag chain. I've also realised the y plates are too short to fit the drag chain where I had originally on the other axis.I'm a little more ahead today - it's the most solid cheese yet.
Just remind me why you have two rails per side and not just one on top? (which can then be aligned with the other side using the 'gantry alignment method' suggested by Jai Stanley below.)
Why not use regular cylindrical rail guides?
I hope this build come to open Build.
Awesome work man! Quick question, why did you get the plates water-jet cut as opposed to doing it yourself on your cnc? I only ask because as I understand water jetting has its drawbacks; such as the angle it puts on the edge and 4mm seems doable based on your previous videos.
Also for a Z axis assembly that tall, you could put the motor on the backside of the Z plate (facing up) and use a short 1:1 belt (which acts as your flex-coupler too) to the top of lead/ballscrew, that way the motor is not way up there performing balancing act, and moving it's weight backwards helps to even out the load on the gantry rails.
My spindle plate started to crack and I just didn't have the time. I work all week and don't live near the workshop, so I didn't have enough time. I've seen some designs like that. I think I'll wait till I put the drag chain on this one and see if I have enough space. Didn't think about the weight - that's interesting. Cheers.
i have another question, if you were going to get the parts waterjetted anyway, why didn't you make them from steel, or would that have been to heavy?
@@jandillingh Yes it's heavy and it takes longer to cut - so a little more expensive. Also I can work more easily with aluminium in my shop.
are you sure that stones would be tough enough? they're obviously very hard, but for something to be tough, it needs to be ductile as well. that's why steel is so tough, it's the right combination of hard and ductile. i think that the reason you haven't seen anybody doing it is because rocks are probably to brittle.
might make a good machine bed though, the weight would actually make the machine more chatter resistant..
Why water jet cutting ???? If you have plenty of CNC machines.
It's about time - the machines I built up to that point could only cut aluminium really slowly, and I didn't have enough time to wait. So I decided to try out the water jet cutting service.
hello what is the name of your profile thanks..
What ended up happening with this aluminum build?
I realised I was using crappy components and didn't like the leadscrew so made the Moot One using valchromat plates instead.
این طراحی فقط برای تک کله خوبه طراحی 10کله را هم بیشتر نشون بدین باتشگر دستگاه سازی محمدی..
When you finally get it built don't cut anything with it. Have the whole thing set in a clear resin block and use it as an anvil. Everyone is a blacksmith these days anyway.
Haha I'll be honest, there's been several times I could have hit this with a hammer.
Please share 3d file on 0:43
how can i have the designs from the tiles.
I have a better design. Look at my later videos.
@@EducatingSavvas thanks I can have dxf designs? mail teslok@yahoo.gr
@@teslok I'll be releasing a physical manual soon which you can buy. I'll let you know when it's is available. 😊
@@EducatingSavvas thank you very much
A good Inventor/designer is able to take criticism. Bad practice hiding comments.
Errr what you talking about?
@@EducatingSavvas Sorry, that wasn't meant for you. I had multiple tabs open. I commented on another persons video about a design flaw that was quiet clear. But they just hid my comment, I was offering advice and possible improvement.
Quite @@thespiderkelly9589
@@thespiderkelly9589 Ok I'm curious - which video? I've noticed loads of design flaws with mine. :/

This was the video in question. Projects never seem to follow through on this channel. At times lots of good ideas and concepts with no end in sight. Please note this is in contrast to your videos and in no way has anything to do your channel. Earlier I mistakenly commented to your video. Good work on the CNC build by the way.
