Magnetic chucks for milling

[Noel]

The boss wants to bring in a magnetic chuck to try on our cnc mills.It is a Tecnomagnete brand I'm not sure of the model #.Any one using them and what is your opinion of them. I would tend to think the holding forces would limit how agresively you can cut and the chips would tend to stick to the workpiece.

About halfway down...

Seems that Hardmill has been using them for a while. He's the man to talk to. Good luck.

I've used a magnetic chuck a few times on the cnc mill worked great. Just be carefull with the size of part and how aggessive you are with your cuts. Use some of the same principles as if your were on the surface grinder. Use blocks around insert.

[PE @ IHS]

I used them with good success. Naturally you can't take monster cuts, but i was taking 5/8 DOC in P20 Moldsteel with a 1" endmill no problem. Make sure that the magnet will still work if the power goes out, not just an electromagnet.

good evening noel,

this should help you. check out machine tool solutions they are located in brampton ontario.

I can't say i've ever seen one used on a mill...but we use them in our grinding operations daily....

 

but hows this for freaky...I have an operator that likes to qualify his part (normally plate steel) having double sided taped the thing to the machine...

That's right - you don't want to have to stop machining just because the power goes out!

 

I know the reason you suggest this Peter but I had to post this reply - Jack would not have let me live it down otherwise...

[Noel]

Thanks for all of the input guys.I look forward to trying the magnetic table.I don't know how serious the boss is as it was the salesman who asked if he could bring it in for us to try.I think once the boss sees the price he might change his mind, but we'll see.

We mill sheets of modified NXT-75, AKA teflon, and we hold them down with double sided tape.

 

And they say nothing sticks to teflon!!!

[Scott Sizemore]

We run Techno Magnets every day. They are a god sent for mold work. I don't believe that they produce a magnent that fails during power outage. Actually when the magnent is energized that's it you pull the plug till until you want to release it.

[Hardmill]

Scott is correct you don't lose magnetism during

loss of power. The table is only energized when

clamping and again when unclamp and demag.

You can actually take the cable off after its

energized.

 

PEACE

Coolant makes the rubber spacer between the polls puff up. I end up milling it off monthly, and i bearly use coolant. Without coolant it doesnt puff up at all. I dont think it would last in a mill running coolant as the norm. But who knows, maybe the rubber spacer isnt even needed and it can be milled away?
