Capto 8 to .250 Shrink

When we have to heat up shrink holders with a torch at our shop, we spin it slowly in the manual lathe in order to heat the holder evenly. Works pretty well.

If you're doing this a lot why not use an induction heater?

Although this vid is a year old, I have used a styrofoam cup, can of compressed air turned upside down to dump liquid into cup, place tool into cup to get super cold, heat tool, drops right in. shrink one, expand the other. Can of compressed air works well too for when the reaming ferry shows up and makes holes just a hair undersized. Dump the cold stuff on your part till really cold, cycle start. Hole is now bigger

[@StefanoLinguanotto]

Works but quite an expensive tool if than you can't remove the endmill from the toolholder because you can't cool the endmill when it's inside.

That Capto holder you had in the chuck looked like something I might could adapt to mount on the spindle of my boring mill. Probably would be no gain though as that spindle assembly is not that stiff a system to begin with.

[@TheLimalha]

ANOTHER GREAT VIDEO !

[@anonymousgeorge4321]

Great video. Thanks.

[@ROBRENZ]

Very nice work Peter! May I suggest lapping in the machine with the lap and the tool holder both rotating. That gives a better chance at not lapping the hole at an angle. ATB, Robin

[@EdgePrecision]

ROBRENZ thanks Robin. I will keep that in mind next time. All these holders are already being used in a setup right now. But I can see how that would improve the runout error. I would just have to figure out how to run both spindles at the same time. On this machine it’s kind of interlocked. You can mill or you can turn but it doesn’t like to rotate both spindles at the same time. This machine does have the hobbing option witch does allow both spindles to rotate in a sinked fashion. I have never used this function but possibly that could be utilized to make it work. It’s just you can’t rotate the turning spindle without having a tool orientated and clamped in the milling spindle. I know this sounds strange but that’s the way they made this machine.

[@ROBRENZ]

@@EdgePrecision The most important part is that the toolholder you are lapping is turning. This insures you are not influencing the axis of the hole. If the lap is stationary that is ok and necking the lap to a 1*dia. engaged length will help to minimize any effects of misalignment of the lap to the part. If the lathe spindle is not locked you could just turn it by hand while the mill spindle is turning the toolholder. The whole point here is averaging all the alignment errors by having constantly changing orientations of the lap and part.

[@EdgePrecision]

Yes I can see the logic in that. And if I ever make some more holders (The chance of this is good) I will do as you suggest. If I can figure out how to make the machine do it. The issues with this machine are. You cant run any spindle with the doors open, and you can only run the milling spindle if the C axis is engaged. Or the turning spindle if the milling spindle is clamped with what it thinks is a turning tool. The way I think I could do what you say is make a program that runs the milling spindle and command a movement in the C axis to rotate with the lap in the bore. While stroking the Z axis such that the lap covers the whole bores length. The more I think about this, I think this would be a most Ideal and repeatable way to do it. Much better than just using a hand drill the way I did in this video. With altering the program I could concentrate on certain areas of the bore if necessary to bring them to size. Thanks again Robin you have made me think about the process.

[@ROBRENZ]

@@EdgePrecision if you hold the lap by just a little bit so it is very flexible you don't have to worry about the lap spinning. Its just technically better but not necessary. Spinning the part to do the lapping is a must.

[@Brrraaack]

A quick workaround would be to just lock the cordless drill or something in the chuck, lock the trigger with a cable tie and let it run. Not elegant but quick.

[@drubradley8821]

WOW!!! Impressive... Tool holder manufactures have upside down smiley faces right now.... LOL

[@silent_tofu7921]

[@nikond90ful1]

Thanks for the video.

[@lichtyc]

excellent! Might just be a coincidence but notice that the runout is consistent with the "wave" in the heat coloring, wonder if that is where that extra tenth came from? Still, 1 tenth at 8.5" gage length is nothing to complain about!

[@EdgePrecision]

That might be possible. I will check that on the other holders when I mount tools in them. Thanks Chris.

[@hinz1]

Runout of less than 1/100mm is really good, considering the distance to the spindle bore. Bearings and spindle taper have to be perfect for 0 runout as well, a lot better than on my old ISO40 machines ;-)

[@ironbrassmachine]

Maestro !

[@gbowne1]

I'm going to be getting several newer machines this year.. one with C5 tooling. Would love to know what to watch out for.

[@EdgePrecision]

Are you talking about C5 live and turning tooling for a lathe turret? They use that here at Center-line it works great. There isn't really any draw back except maybe the price.

[@gbowne1]

Yes, thats the one Peter. Thanks. Yea I see its not cheap new. Ill probably look at ebay first. The other machine has VDI40 and also KM40. The other one comes with some tooling. DA100, ER32, etc.

[@dws_damiansworkshop]

Well done! I now want to try this for my self made tooling system for my cnc converted mill. Can you give me some Information on the required nominal bore diameters for shrink fit holders?

[@EdgePrecision]

For smaller diameters say 1/8" to 1/4". Around .0008" undersized. So for 3/16" like these .1869". For larger diameters around .001" under. But you have to try this out for yourself. Make a straight extension to experiment. You don't want to have to heat it red hot to get the tool in. If that's the case your bore is a little to small.

[@user-sd3ef7jh3z]

Good job

[@ROBRENZ]

Hi Peter, have you considered using "super chatter free" or "Diemitech" by Mitech metals for your shrink extensions? Machinable and twice the modulus of steel. I have used it for grinding quills and boring bars with great success.

[@EdgePrecision]

I have never used this material. I have used Tungsten before for boring bars. What is the expansion rate compared to carbide. Would heat release the tool OK.

[@ROBRENZ]

@@EdgePrecision Good thing you thought about that , its roughly the same as tungsten carbide. That would not shrink so well.

[@richards6452]

Peter, look at dental milling tools, may be useful!, used to mill crowns to within a couple of microns, cheers, Richard

[@EdgePrecision]

I am kind of thinking they are not this big/large but I will check into it. Usually the machines that do dental work have smaller spindle sizes. Or are you talking about the end mills themselves? That may have possibilities. Thanks.

[@ianpendlebury3704]

Fascinating as always. Now a question, not a criticism. Could you not make the whole Capto unit yourself, or are they too precise for your equipment? Or perhaps it's just not cost effective to do so?

[@EdgePrecision]

If your talking about making the taper connection. Yes that would be beyond the capability of my equipment. I would need a CNC grinder and the proper gauges to make that trigonal taper.

[@OMY005]

Nice work. Nothing in the Iscar Shrink In range that would suit? ST 25X200 SRK looks close

[@modris2980]

Is there a difference between doing OD before ID? Is there a difference in some cases when you don't have much material in the walls between ID and OD? Also wondering what is your hourly pay because if you calculate that into tool costs it might be even more expensive than outright buying it.

[@EdgePrecision]

Yes you should rough the OD first, it may relieve stress in the material. Particularity in this case because I was turning off quite a bit of material. Because I wanted the run out to a minimum. If I had done the ID work first this could have caused a problem with that.

[@aus71383]

I know the heat is supposed to stay in the chip, but I have to imagine those parts are warm to the touch when you're measuring them. Do you take the temperature and coefficient of thermal expansion into consideration when you're measuring those parts? I bet it would be relatively simply to create an excel spreadsheet that shows target measurement, material being machined, and temperature - shoot the part with a laser thermometer, measure, and then convert to room temp dimension. I realize I am probably overthinking this, but I've already typed it now. Great channel, great content - it is helping me a lot with pondering what parts to design, and what isn't realistic.

[@EdgePrecision]

I machine parts in videos if possible without coolant. Just for the sake of the video. But I let them cool down or spray coolant to cool them before measure (You don't see that). Normally I would of course be running coolant and this wouldn't be a problem and I did for the other three parts in this video. I have also found those laser/infrared temp gauges don't work well on metals. But if you know the thermal expansion and temperature of the material it could be possible to calculate the change from room temp.
