My mistake, 4 Kn is 900 lb force.
We appreciate both units though that's really great for international viewers
Instructions not clear, aluminium flew off and broke my glass...
Aluminum is not magnetic tho
@@HiepTran-pv9zr Woosh
@@HiepTran-pv9zr no way really? is stainless steel also made out of aluminum as well? cause my chunk also flew off.
you obviously need an aluminium magnet duuh
@@mobilePCreviewsstainless steel has less iron in it because it is enriched with more carbon and other metals so it disrupts the magnetic property if the iron
We move stuff on the magnets all the time. You can't push things too hard or it will move. It's not a constant pull on the part it's pressure applied in a direction while vibrations from the cutter make it move. Cutting all the way to the magnet also sucks, you can't get the chips off the magnet and inevitably cut chips and make your finish rough from chatter. I will leave a couple thousandths on the outside blow all the chips off then come back and finish. Magnets are ok we've used them for years but they have limitations
That’s a cool set-up! Schunk really has thought of it all.
This is the coolest work holding I’ve ever seen! Great video guys!
Great product from Schunk! Entertaining video with everyone pulling with the strap😂 Nice work
The agony in the beginning from Jessie pulling me the opposite direction was not fake 😂
I will pull on you anytime 😘
we have a Quickmill with a Fanuc Controller and magnetic table and we machine motor grader edges for Cat, and we just replaced the original system of magnets with the exact same one as your using and it is allot more powerful than the original, most of our stuff is only 3 to 4 operations [pretty basic] and is mostly Boron up to about 450 lbs each at the heaviest part and need to take lots of care unloading it with a 1000 lb capacity jib crane, it is a good time to run this machine even though it is old , Great video Barry 👍
YASSSS MAGNETISM ! That's such a cool workholding and awesome video
Do you ever have issues with residual magnetism on the part? Do customers ever have call-outs on their bids to not have residual magnetism on ferrous parts? Would you be able to reduce chip buildup by using non-ferrous materials as an insulator on exposed magnetic chuck surfaces?
Yes, finally I’ve been using these magnets for 14 years now when you’re working on a block of steel that weighs 7000 pounds and it’s 3’ x 2’ x 2’ these magnets are a dream
I love it how Jason Segel is the face of Titans of CNC
I don't know why magnet chucks like this aren't more common in job shops. It really has decreased setup times significantly. Especially for round and odd shaped parts like this.
Because its a hell for tool life, unless you can either:
1. Feed so high the chips dont clutter, which bring higher chance of the part moving.
2. Blow it clean either once or multiple times during or between operations, which adds quite a bit of time to the operation. And dont you dare do a 2nd finish pass for a smoother finish or tighter tolerance without blowing inbetween.
These chucks are great for laser or otherwise cut pieces, but at the same time absolute sucks at machining them. Try a medium sized water cut 30mm piece with a 1-2mm unevenness in surface. That sucker will either get eaten or yeeted by the mill.
Vices on these will also move over time. We had a setup running for a week or 2, and the vices had moved 0.1-0,2mm.
Its a niche product for special parts.
Talk about teamwork haha! Great video 🔥
used a mag vise for years. we had wear blocks bolted to the table. you could take specific of them of to drill a hole or to lift up the part for side op's
Awesome Barry keep on keepin on LOVE IT!!!!!!!
At my previous workplace we used magnets for a lot of our final operations because the parts tended to have a lot of different shapes and angles which made them impossible to hold without a part-specific set of jaws for the vices.
A lot of the time we had to machine past the base of the parts, right down to 0.001 above the magnet's surface, depending on the chamfer on the part.
We had some parts move around due to tool wear, and when the tool got to the base of the part near the magnet's surface there would be a lot of chips piled up around the parts causing all sorts of issues.
Most parts came out alright, but every scrapped part was a significant loss due to all the hours that had gone into the previous operations and hardening of the material.
Using a magnet for larger parts is amazing and for machining parallel is so easy.
Curious for aluminum if you could make steel clamps that are essentially steel blocks to hold down aluminum pieces.
Bell cranks for a rocker arm suspension? It would be great for you to briefly describe the part and what it does.
Great video and instruction, but there is one mistake, at the first operation you have to use 3 fix poles and on the rest of the size of the workpeace fleksible poles for clamping without tension‼️ but the rest is 🔝
next time tell the new guy to get the copper magnet!
They are cool but will quickly drive you nuts. Best mags I have used is Apods. The mount to the table where you need them and decreases chip buildup
Just like with surface grinding your parts should be de magnetized before sending them to a customer. Amazing just how quick the part will become magnetized
This magnetic plane is actually made in Italy by SPD srl for Schunk
would be a great way to fixture things my workplace... to bad like 90% of the stuff in the mill is aluminium.
though, i am waiting for the continuation of the big valve housing that was mounted with the zero-point system :D
Strong enough even if you don’t prep the face which sits on the table ? I was asking myself if on these magnets we need absolutely flat surface or not. But I see that’s raw stock so I think it’s perfect solution and great for mould and die industry🙏. Great job as always ✅. Hello from Eastern Europe 🇷🇴🇪🇺
I have used one of these tables before and you definitely want a mostly flat piece of stock. I have dealt with proven parts all of a sudden kicking or moving because of a bow that wasn't caught.
I wasnt even this early for my own birthday
Wow the chatter in those corners on the shot of the final parts lol
How do you extend toolife on something like that? We get a lot of re-cutting chips with using our magnets.
2) we have done multiple step overs (6-8%) with dynamic mill and have had our parts slip and move on us using .500 Endmill -which wouldn’t be a lot of side load, but it manages to move the part… any tips?
For recutting the chips, I would use tall pole extensions to keep the part as far off the table as possible, use thru spindle coolant, and make sure that when backfeeding you use a z lift of at least .25". For the part moving, do what I did in this video, and machine a pocket into your pole extensions. Then the part CANT move
I would love to work in a shop with that❤
How much does this MFRS table with remote control and extra soft pole for milling cost?
Roundabout?
Or the Table with remote control itself?
Are the drillbits and machine not bothered by the magnet? Or is there like an area of how close you can go to the magnet
The magnetic lines of flux extend about 3/4" (20mm) above the table. If the tool is closer than that, there will be friction and heat in the tool from passing thru the magnetic field, but it won't be enough to hurt the tool
#Titans of CNC Machining
If you break a tool in your shop, do you produce/machine your spare parts by yourself or do you have to buy and order it like any other factory?
millions of dollars of CNC gear and you're using Ryobi?
😂😂😂😂😂😂😂
Could you save time and money using a sand casting and just machine in the critical features?
Not for small numbers...😂😂
What does it take to move it? Forklift?
Do the holes go all the way through?
04:14 - daily dose, is it you?
If someone could invent such a magnet for aluminum haha.
That magnet didn’t even budge!
I feel like the use case for this is kinda limited. Can you use this to hold another vise or fixture as opposed to t slots?
Yes it will hold a vise. I actually indicated one in to within a tenth, then turned the magnet off and on several times and it never moved
Ok that's pretty cool
Am I missing something with the math on the holding force?
Yes, you didnt factor in that im bad at math
@@barrysetzer haha so am I, thats why I had to ask😂
Boom !
some easy fixturing but the chips are a pain.
Work holding is the secret
huh, if 1 pole is 90lb and if you have 84 poles, aka 84 times 90 that would be 7560lb, how do you get 74000lb?
They’re machinists, not mathematicians give them a break
@@aklef this is basic math. Machinists need to be able to do basic math and some precalc I'd say at the minimum. A problem like this should be equivalent to 1 plus 1 for them.
Am I missing something on how 84 poles at 90 lb each is 74,000lbs? Should it not be 90*84=7560?
I screwed up the math its 900lbs per pole
@@barrysetzer Thanks for the reply! Now that's impressive!
That surface finish looks awful
🔥
So you guys are going to develop an electromagnetic chip removal system and send me a free one?
boom
Well you can do non ferrous too if you are creative enough..
Pfff, it can hold the part but cannot hold the chips 😅
Watch the video properly
Your stop bolts are too long-might have buggered those threads…
It'd be hard for me to trust it.
4kN is more like 900lbs i think
Oops see this is why I dont math
@@barrysetzer Still impressive, keep up the good work.
Ahh yes. There is nothing as repeatable as a bolt location 🤣
Nice advert 🤡
