Making a propeller with Proxxon MF70
HTML-код
- Опубликовано: 11 сен 2024
- Proxxon MF70 was upgraded to a 3-axis CNC.
The propeller was based on Trumpeter 1:200 Missouri kit part.
Although the finished work is not 100% perfect, but good enough for my modeling usage. The precision is within 0.05mm.
And it can really be done by myself with a 3-axis CNC has already exceeds my expectations.
nice, didn't expect the precision to be that good
Me too. This is out of my expectation. Also I've made many attempts and improved the programming and processes. The final works are even better then the one in this video. 🤗
@@eddiejiang6789 What was the total runtime?
@@TeslaAtoms According to my final programming, Side A takes 2 hrs, Side B takes 2 hrs and 40 min. Thus total runtime is about 4 hrs and 40 min.
@@eddiejiang6789how loud is it if you don't mind me asking
@@rogaldorn605 I didn't really measure the loudness. I would say that I'm ok not to wear any ear buds while it is working. Also I do the project in my garage thus no bother to my neighbors at all. But I'm not sure whether there would be complaints if it is in an apartment.
Hi, I don't know what material you used, but do you think it would be possible to use this milling machine to make grooves in Titan Grade 5 sheet metal or stainless steel?
Hi, if I remember correctly, according to Proxxon official website, this machine is NOT suggested to work on hard metal. In this video, I used aluminum and it works perfectly well. Brass should be ok as well. I also used it to work on cast iron, which was also quite good. Never tried it on stainless steel. I think it might be workable as long as you set lower parameters (feedrate, cutting depth, etc.)
Also, do you think it would be possible to make a vacuum table for the proxon?
I've seen it done to many lathes, but is it possible for such a small mill?
I've heard vacuum table but has little knowledge about it. My personal view is that MF70 might be too small to install a vacuum table. Even if you do, it might reduce travel distance of Z axis since I guess it will take more heights than the T-slot. That may cause trouble when changing milling bits, or using tools like edge finder etc.
Hi, could you tell me, how's the precision?
Im searching for something small for my projects but i need a mill which the tolerances are +- 0,02 max.
What are your experiences?
Hi, MF70 might not be able to meet your requirement of precision. The spindle Runout will be at ~0.03mm.
Which CAD program did you use ? And how did you attach the second side of the propeller to the jaw to be perfectly aligned with the first side ?
Thanks :)
Hi, I use Solidworks for 3D modeling, PowerMill for CNC G-code programming, and Mach3 for machine control. As for alignment of B-side, firstly, I used square material rather cylinder. I draw a mark on the side of one corner. So after flip it over, it is easy to match the material with the position when I program G-code in PowerMill. Secondly, I use an Edge-finder to make sure the side of the material is aligned with X/Y axis (use 2 points on one side and make sure their X or Y readings are identical). Hope this can answer your question.
@@eddiejiang6789 Thank you :)
What is edge-finder you used?@@eddiejiang6789
Awesome. Do you know what the terminology is for the part of the workpiece that you use to secure it in a chuck/vice/clamp?
You know, part of the workpiece cant be worked on. You smartly used a chuck for the second side to be milled on, etc.
How is this part usually removed? The rectangular one. For you, it worked because you had the cylinder on the other side. But otherwise? Saw it off?
Thanks a lot!! To be honest, I'm just a beginner in CNC. I don't know how to call the part in English. Tried to look for "CNC toe push clamp" on Amazon and EBay but failed to find a same thing. Only there are 2 similar clamps but they are 3D printed. I don't think they will be strong enough. I bought it on Taobao (Alibaba's Chinese branch) and the name in Chinese is "多功能工位防翘蛤蟆钳". It was screwed in the T-slot on the workbench with a M6 head hexagon socket screw and easily to be removed. Hope this helps.
Milling table toe clamps or low profile side clamps.
Where can we get the chuck? is not included. Any link appreciated
Do you mean the chuck or the clamp? As the chuck on the spindle was the original one comes with the machine. As for the clamp, it was bought on Taobao, the Alibaba in China. Below is the link: 【淘宝】m.tb.cn/h.52wJMfK?tk=AeFndDlfMfa CZ0001 「立万多功能工位防翘蛤蟆钳精雕CNC侧面固定精密OK夹具平口台虎钳」

Very nice. You should make a full tutorial
Thanks a lot! I was thinking of just demonstrate the potential of this small simple machine. Maybe next time I can make a more detailed video clip.
Hi, can you send the clamps link? Tks a lot!
The clamps was brought on TaoBao (an e-commerce platform like eBay in China). I don't know whether you can access to it? If yes, definitely no problem share it with you.
Where did you buy the upgraded cnc kit?
The aluminum assembly accessories we're bought on eBay. The step motors, drivers, and controller was bought on TaoBao, the e-commerce app in China
