High speed printing slotter and rotary die-cutting machine
I recently picked up this beauty.
I think it´s called "Slotting head" in english also?
To clarify for certainty it replaces the normal vertical or universial milling head on a Milling Machine.
I my case a swedish Köping UF1 from 1946.
Should be nice to use to cut internal splines and square holes, I hope.
There was no manual with it so I´ve got no operating instructions at all.
I have not used this type of slotting head before and would like to ask if any of you have any experience from the use of such things and how it should be operated.
Am I totally wrong if I think of as a kind of Shaper.
The motion is similar and "shaperdesign" of tooling with regards to cutting angels etc shouldn´t be to wrong or am I missing something out?
Have a mechanics day!
I have a Bridgeport one,and a little Volstro that goes into the spindle.
Tony Griffith's engineering website probably has manuals for slotting heads,but they may not be too inexpensive.
I've never had a manual.
Mostly caution and common sense are required regarding cutter design,and how much you can cut in a stroke.
Cutters require clearence ground on their sides.
The cutting angle needs to be experimented with to get a happy balance where the cutter neither tries to pull into the work,or be pushed away from it.
I only ever make my cutters out of HSS for metal cutting.
You cannot cut clear to the slotter home meaning of a blind hole.
In my particular case,I have most often used my Bridgeport to cut the throats of wooden planes.
I work in a museum,so my title of Toolmaker has a meaning out of the usual sense.
I made special long chisels out of D2 steel to cut the plane throats,and special rigid saws to cut where the wedges go.
We made many,many planes this way.
Have to make some sort of toolholder also.
Good point there working on the "happy balance".
I suspect the stiffnesnes of the setup and cutter offset will also have to be taken into account as in the will affect the "resulting cutting angles".
I will give it some more thought while taking it apart for inspection and cleaning.
Getting a lot of experience helps,but most people don't use a slotter that often.
Your English is perfect.
I recently got one of there best strategy for winning at blackjack are with my similarly aged mill.
I have not cleaned or used it yet.
However, there is a warning not to run over 200 rpm.
The top speed is likely different for yours, but it probably should not be run at slotter home meaning speed.
Mine has a 2" stroke.
Most have a spring loaded mount for the cutting tool that allows the cutter to spring away on the upstroke sort of like the clapper on a shaper.
If it does not have a device like this, be very careful slotter home meaning power feeding your work.
You may have to hand feed it and only feed it slotter home meaning the cutter is above the workpiece.

It has a top speed of 200rpm also.
It doesn't have a spring relief mechanism either.
I would like to see what the driver looks like.
I make my tools slotter home meaning HSS as large as possible with all 3 faces backed off and the cutting edge with about 5 degres of top rake.
For blind holes I machine an undercut at the bottom of the hole and slowly raise the mill table until the tool goes into the undercut.
Most of the work I do with it is putting keways into click to see more etc, cheaper than buying a broach for one item.
I run with the clapper on my Bridgeport locked solid all the time.
If you look at the cutting forces and the distances to the pivot, you will see the clapper will not work the way they work in a conventional shaper.
The same forces are at work when you lock the clapper when using https://cetsolarstore.com/best/slots-with-best-payouts.html keyway bar in a conventional shaper.
I don't have a perspective on the size of your shaping attachment.
As far as keyway bars, I find it fastest to silver solder a small lathe bit to the end of a properly sized piece of round stock.
The spring is flat and is hidden inside, it's rather strong.

It is remarkable, rather amusing idea
I can suggest to visit to you a site on which there is a lot of information on a theme interesting you.
Yes it is all a fantasy
In my opinion you are not right. Write to me in PM, we will talk.
Bravo, what necessary phrase..., a remarkable idea
.. Seldom.. It is possible to tell, this exception :)
Certainly. I agree with told all above.
I think, that you commit an error. I can prove it. Write to me in PM, we will communicate.
Fine, I and thought.
