There is a tapered pin right under the square stud at the top of the draw bar.
I removed the pin but i couldn't remove that top cap.
I would like to remove the drawbar to change out the S20x2 buttress thread

How do I do it?

Thanks

First generation FP3, is horizontal quill spoke supposed to be easily removeable ?

Or is it supposed to be permanently attached via two set screws ? I ask as the set screws are seized on mine and I wondered if it could otherwise be removed and used with the vertical head 12mm square ? However, every photo I see of a first generation FP3 shows the horizontal spokes in place and a 12mm square wrench used for the vertical quill, so I suspect the horizontal spokes are meant to stay in place....but still I wonder what one would see once it was pulled off....a 12mm square or something else entirely ?

Having rambled on about that, is anyone here aware of a small 3 or 4 spoke handwheel with a 12mm square mount ? That would seem more pleasant to operate than the simple 12mm square wrench that it came with. And yes, yes....I could make one....but got better things to do than that.....plus probably no one but me would care, and I want to sell the machine anyway.

Hello Guys,

Last chance to get this Mikron!!

I have gone and installed the rebuilt spindle cartridge 2 weeks ago and run the spindle in for 8hrs reaching top speed of 10K rpm. Ran the spindle for 2hrs after reaching top speed no problems see videos below.

There are picture and videos below. I took pictures to document the power up of the machine since it had be sitting for almost 8 months. The machine booted up error free!

the only exceptions was a couple of error codes relating to the spindle low coolant solved by adding more refrigerant that was lost when disassembled.

The machine is no longer under power and has been disassembled in prep to move to new owner!

Included are about 30 tool holders,retention knobs, collet set, spare parts used hydraulic pump.

Step down transformer 480 pro to 400 sec included unless unwanted to save on shipping cost.

Please call serious inquires only machine must go the building has just been sold!

Deckel FP50CC/T Spindle Speed Changer Won't Go Anymore

Well, after a few years of getting the Deckel FP50CC/T going, today it seems it doesn't want to go to high speed anymore.

The machine will go 'clink, clink, clunk, clink' as the gears try to line up. When it goes 'clunk' I think it is actually going into position.

This isn't the first time this has happened. Before, we learned from the old company that had this machine if the oil was cold it would do that. We are currently at 30°C so I don't think that is the problem now. It was running on Friday okay with a few of the 'clink, clink, clunk, clink's but it would get in position after two tries.

My thoughts are that there is air in the lines somewhere and that is causing the issues. I cracked the lines to both sides of the gear changing cylinder. I did find what I think was air on one side, but after a bunch of priming, no real change in result. I can't find instructions on how to prime the oil system either.

So now I am stuck at 700 RPM. Any suggestions?

I removed the s20x2 female buttress thread drawbar
I am changing over to mt4 taper with 5/8-11 female
so i am going to make a 5/8-11 drawbar with a male end

Question: the stock buttress drawbar was secured in the spindle by a threaded sleeve and it had to be removed from the bottom after the sleeve was unscrewed

Is there any reason i can't make the new drawbar similar to a bridgeport drawbar that can be lifted right out of the top of the head?


Thanks

Piggy back spindle mount

I am going to mount a Makita trim router to the quill of my Deckel FP4NC and am looking for opinions on my design. I will be using this spindle for machining wood with mostly 1/8" shank end mills down to 1/64" dia. I will be fabricating the mount out of 1" ALUM plate and using 1/4" cap screws to clamp mount to the quill and router. Here is a pic of my design, it is as basic as I think it could be.
Also if I clamp onto the quill how repeatable do you think the spindle location will be if I extend the quill in and out?

looking for a dovetail cutter

August 27, 2017, 5:34 am

I need a good quality but not crazy expensive dovetail cutter for making some smallish parts in cast iron. (150mm/6 inch long 18mm deep dovetails) I don't want Chinese junk but the only only other thing I have found so far is a solid carbide cutter for something over 600USD equivalent. This is for running in my Schaubln 13 mill and cutting SG cast iron so I won't be hogging out material and will cut as much as possible with end mills etc before hand. The part is unfortunately not doable with a horizontal cutter given access issues so I need to use the vertical head. I wish I had a shaper or planer for this but I should be able to do it with the mill, it just requires the correct tooling.

I have seen some people making dovetail cutters with triangular carbide inserts which I could do if there is nothing else to be found. I could also braze carbide on a home made cutter and grind it to shape with my cutter grinder but I am not going to get more than one or two cutting edges if I go that route which seems like it will make for some slow cuts.

Any ideas or suggestions?I am only prototyping a couple of parts, so figure 8 cuts total. I just can't see Chinese HSS doing the job and don't know where to look for something else that makes sense for my application.

thanks

Ok this is in the manner of a test..
Since my loss of a hosting service (Photobucket) by their change in use policy, i wanted to see if i have gotten the posting of photos that are hosted within this forum...
So thought some might enjoy seeing some of the work going on here..
Subject is turning some heat treated stock (4x4) into connecting rods for a 1913 Mercer (perhaps the first real sports car...big motor light chassis)



Running FP4NC with 3" inserted face mill...Depth of cut .100" Feeding at 8.5 " /min Material is heat treated 4142 at aprox. RC 32plus....
Material is rough 4"x4" and 16" long.....
Doing 4 of these....With the potential to make another 4 rod set....



Note use of twin vises.



Not earth shattering stuff here, but for our shop this is bordering on "Industrial".....



Bit more to follow if this works........
Cheers Ross

Strange?? FP2 Coolant Pump Pipe

Hi Folk

My FP2 came without a coolant system and I'm now rebuilding the system to it's original state.

I've got the FP2 Coolant pump and associated chain and it's connected running as it should.

I know there is a feed pipe from the sump to the pump with a bend in it to keep oil pump wet lubricated.

I have tried several sources to get this pipe and I have been offered something very different to what I was expected ... has anyone seen this pipe/tank fitted to the FP2?

I'd appreciate any inputs

While at auction and having passed on a Aciera F1, I picked up a Rawyler FT2. It is in fairly good shape, but was a production machine and slightly different than what i've found on internet. It does not have hand wheels/dials for any of the feeds, only full stroke levers.
Anyone with experience with this particular machine? I would like to convert/modify it to original/std. form with hand wheels and dials. Any info/Manuals would be much appreciated. One of the former wokers at the co. is supposed to be digging one up for me, but.....

Moving a Deckel GK21

Hi, all.

I'm a brass instrument maker about to set up a home shop off the back of an old Belgian rowhouse, and am trying to figure out if I can get a Deckel GK21 (1040 x 1250mm / 41 x 49.2 inches according to spec) through a 72 cm / 28 in. narrow spot in the hallway leading to my shop. Looking at diagrams and pictures of these machines, I figure it should be possible to take off the tables and pantograph arms for moving, and carry it in piece by piece. Is that a reasonable plan? Or a fool's errand?

The only other option would be to have a crane in to lift it in through the roof, over 6 stories - which is going to break the budget, I'd imagine; if that's what it comes down to, I guess I'll write off the GK idea.

Anyone have any suggestions?
Thanks and best wishes,
Nathaniel

What MT4 tooling for a FP1? Deckel only, any MT4, special w/ custom drawbar, or?

Hi all,

I am looking at a mid 50’s all lever FP1 with a MT4 to S20x2 collet adapter but would would like to use more than just collets.

I would be hesitant to use standard MT drill bits as it looks like it would be an ordeal to get them out without impact on the spindle bearings

For milling, I would need a drawbar of course. I know lot of other mills use use MT tapers adapted for a drawbar but expect that they wouldn’t work with the Deckel drawbar

Deckel must have made more tooling than collet holders for the FP1, are they readily available?

Thanks, -Paul

FP1 Horizontal Arbor Complication

September 4, 2017, 6:09 pm

Using my FP1 horizontal spindle. The Deckel arbors have a bearing surface at the outboard end that runs in the overarm support. The arbor I have to use for this particular application is not Deckel brand and does not have this bearing area, instead it has an internal 60 degree center drilled, I'm sure left over from when it was ground. Anyway I would like to run a live center in this center drilled outboard end of the arbor. Unfortunately there's really no provision on the outboard support for a live center. I could grind a 60 degree point on a piece of drill rod but there would be no way to generate any thrust to keep the point in the arbor. Clear as mud? Anyone dealt with this?

Keeping in touch!

Hello All,

I first wrote in April as I'd just acquired my FP1 and it had a collet adaptor stuck fast in the horizontal spindle. Many thanks for all the helpful suggestions, it came out without too much bother once I'd romoved the drawbar and made a threaded puller. The best advice, thanks, was to buy a collet sleeve with a threaded extractor ring which of course works perfectly.

I sorted out the electrics with a Teco inverter, 240v single phase in, 415v three phase out and realised that I could connect directly to the motor's high speed windings. I now have soft start, braked stop, variable speed and reverse. So useful for solid tapping. I don't reduce the speed much below 50% but the power loss isn't apparent until way below that. I was also able to get rid of the enormous control box as I don't have anything else to run from it. The inside of that cabinet is like U boat technology and it weighed a ton and took up too much space.

I have a problem with the Acu-Rite DRO! Error code E2 comes up on X axis which I believe is dirt or coolant in the readout. I'm not looking forward to stripping it down, has anybody any words of wisdom on that or am I being unnecessarily cautious?

I took Bruce's advice and installed a winch as I'm not as young as I was but the only piece of equipment I've used so far is the dividing head, set vertical with the 12" face plate. Nearly everything I've done has been round but I can easily mount a vice on the plate.

My main message is: what a fantastic machine, compact, rigid, powerful, very accurate and extremely versatile.

Schaublin 13 high speed head mystery collet adapter

September 13, 2017, 5:14 am

After some time of not using the high-speed head I have for my schaublin 13 due to a lack of collets (and having no idea what the collets are despite considerable research) I have started trying to make an adapter to use ER20 collets. This is for drilling with the quill and light milling only (max speed is a bit over 6k rpm)

I tried hard turning a cheap ER20 MT2 adapter to fit the taper but have run into some difficulties. My big lathe cuts the steel just fine and leaves a better finish than the original grinding and the fit seems ok with blue in the spindle but there is considerable runout when I test fit it. This could be how I held the part between centers using the mouth of the ER cavity and it is a cheap collet so that might be part of it but no matter what the location of the adapter doesn't seem quite secure as it depends on the unground bore to locate the end of the adapter.

here is what the current adapter looks like:
Shared album - Luke Rickert - Google Photos

The plan was to use the threads on the spindle nose and a special nut with pins and a slot to hold the adapter into the spindle if that makes any sense.

here is a sketch:
Shared album - Luke Rickert - Google Photos

The rough parts of the bore are not that rough in reality but are not ground like the area near the end. The contact angle is 15 degrees as far as I can tell but as I have said I haven't found a spec anywhere.

It seems like I need to make something that can be more or less permanently attached into the current bore and then the ER20 cavity turned into the end to ensure concentricity.

I am not sure if there is enough material to grind the spindle out to an ER20 cavity which is too bad as the M25x1,5 thread would allow the use of off the self ER20 nuts. I could perhaps make an adapter and special nut to use ER16 which would fit within the current bore and is big enough for the purposes of this head.

I suppose what I should do is disassemble the head and remove the spindle. I am not crazy about taking it apart but it seems like the most logical way to proceed as any workable solution is going to end up with the spindle on the lathe.
I could attach something into the bore and then true it on the mill using a cutter held on the table but I would not be able thread etc so it would have to be a two part (glued) solution.

Any thoughts?

So I am not sure if this EPROM Data i have is OK.
Does anybody have this version and can sent it to me please ?

Also the Machine shows the LED 3,6,7 on the NPP90 which stands for "Error in Communication between PC and CNC".

Thanks for ideas what also should be checked.

What standard does Schaublin use for what they call ISO 30 Spindles

September 15, 2017, 6:01 am

As far as I can tell the International Standards Organization does not have a standard nr 30. There is ISO 297:1988 (7/24 tapers for tool shanks for manual changing) which looks close from what I can see without buying it but the ISO website and the wikipedia list do not include anything called ISO 30. Is what Schaublin made the same as DIN 2080-1 without a grove or perhaps there is another standard in play such as NMTB. It seems like standards just make things more complicated as they give the false impression things are actually standardized.

I ask because I need a few tool holders for my 13 mill and am frustrated by not having an accurate search term. I was thinking I might get some Bison holders as they seem to be a good middle ground between the cheap chinese and super expensive Swiss parts. Has anyone tried Bison Type 7311 holders in a "ISO 30" Schaublin head? I can't find a dimension on the length of the end but they appear to be M12 threaded anyway.

This is from the Schaublin tool holding catalog:

Which would imply that "ISO 30" = DIN 2080 at the current time but what about 45 years ago when they made my milling machine.
