Thread: HAUSER 3SM

Ok, these make more sense, fixed one of the push buttons, added the last of the wires and a little more detail to the contactors.
I'm not sure whats going on with the control wires to the relays on the autofeed(but I'll sort that out once I've had a chance to check what I've done so far).

Stuart

Had some time today to have a bit more of a look inside.
Taking the top front cover off reveals this. The red arrowed gear is the top of the eccentric speed control. The green arrow is the slide for the dial indicator. Taking the cover off the dial gauge a little shower of yellow pieces of plastic feel out. hmmm That's not so Swiss, nor as keen observers will note is putting the rear cover on the dial gauge back to front(I guess the serial number. clearance counter bore and the fact that you cant get all three screw holes to line up wasn't enough of a hint...lucky for me the screw didn't fall out. I assume also that at some stage the styles had a ball in it...Still dial indicators I can do

Stuart

I've been doing some cleaning while I think about how I'm going to wire this up. Earlier I was thinking I could get away without power Z, a little check of the manual feed, 170 turns to the inch! I NEED power Z

Might have to take the table off as I found this block under the table, I'm pretty sure that explains why the X axis lock doesn't work.(including the damage to the table)

This is a picture of the leadscrew comp. The height of the vertical plate moves the arm which moves the 0 and vernier scale.(not sure if it should be resting on the flat or not?)

Stuart

Well somewhere a fitter knows why the back was cut off this machine(I'm guessing to get the gearbox out at some stage) and why there is a 2 speed pulley on the motor but not the gearbox. Oh and also what the red arrowed Hex is for?

Here is a picture of the spindle motor. Would be nice to four screws instead of 2. Still no idea how fast is goes but its one of the higher speed ones I believe.

Getting closer to rewiring. Just need the wire now.(just putting the picture here because its easier for me to get in the shed lol)
41x0.16mm 1 Black, 1 orange, black outer. Wont be the end of the earth if I have to change colors as its all of this wire that needs replacing.

Had the motor running on 240V. The feed on the eccentric is about 20 turns for 0.100"(don't recall if that's radius or diameter)

The ball missing from the dial indicator is 2mm.
I assume carbide would be the way to go(though granted for the amount of work its likely to get it wont matter much.

I think that about covers it.

Stuart

Looking at your 2 speed pulley, the size suggests to me a 50Hz/ 60 Hz conversion. Looks like it's on the 60Hz pulley at the moment. Once it's spinning check the speed and see whether it needs to be flipped over to drop the speed down 20% to match specification.
However, all I can suggest with the red arrowed hex is a tilt sensor (did Hauser ever make pin ball machines?). Seriously it could be a number of things and you may need to open it up to check. One possibility is a thermal sensor of some type. These are normally in a piece of steel so they have a thermal characteristic similar to heat going into the machine rather than the air around it.

Michael

Hi Michael,

Didn't give you much to work with did I?
As yet I don't have a spec on what the outputs should be. Though as both outputs are steplessly variable, would they bother with two pulleys?

I'd originally thought the hex was an adjuster for "something" in a flexible tub, not electrical as I didn't have any unexplained wires. As above both outputs are variable, so what other adjust could you want? I gently put a spanner on it this morning........it would seem to be a drain plug, though as no oil came out that's still just a theory .

Stuart

Maybe it's an Oil filler or breather?

On the pulley, maybe it's reversible... 50/60Hz as Michael suggested. But with a VFD it doesn't matter so much.

Already got one of those, I think, its hard to tell as there is a lot going on in a small space.

But both outputs of the gearbox. One for the eccentric drive and one for the Spindle Z powerfeed both have variable speed systems. No graduations I've seen, just "<<<slower...faster>>>".....So would they really care that the input was 20% out?.... maybe they would lol

Going to try for a manual soon. I think I've collected about as much info as I'm ever going to get from the machine.

Stuart

Well I got a reply from Hauser.
Sadly they couldn't be much help.

They said "the machine must be from the end of the 50's. They have no more spare parts, and all the manuals are casted away since 3 years, according the company management."
Just missed out

"By comparing the pictures (attachment), your machine has no U-axis (with the black grinding motor) below the round rubber bellow, also the big hand wheel is not present. Maybe that is a modification with a bore head. Bore machines was also produced by Hauser."
The Z is there he just couldn't see it as the air spindle seems to be built in. Later models used electric spindles. I don't think it can be a boring machine as the top of the column I've seen on their jig borers are completely different. So I'm still guessing its an earlier version. Might never know.

Stuart

Time for a bit of an update.
Turns out these gears aren't always in mesh. They are like the back gear on the lathe, loosen the square stud at the top and engage back gear. So the eccentric is 2 speed and variable speed(and now it has a VSD as well lol)

Well they could have fixed the burnt out motor properly, but no someone saved a couple of bucks* by not bringing the star point out of the motor to the terminal block on the back of the machine base, which would have made changing to delta a 5 minute job.

https://www.woodworkforums.com/attach...1&d=1398318061

So now I have to decide if I dig the star point out, run it as is or use my 415V VSD

This is running in star on 240V...... but it can take a few minutes to get up to speed.
Shows the taper grinding (set on .5 degree I think), variable quill speed and stroke adjustment

The power Z defiantly needed to be delta as it would only turn at about 20RPM moving the column down.(but as it hadn't been "fixed" it wasn't a problem)

(ok so not the most exciting video ever)

Missing a roller in the quill and it appears to the the wrong size belt on it.

Stuart


*I'd hate to say I wouldn't have done the same............I mean who is ever going to have 240V 3 phase? lol

Hi Stuart, great looking machine, and looks like it's coming along nicely, did you think of trying to decrease the base frequency to get more power from 0-25Hz.. Remember the 87Hz trick, well this would be the opposite, set the rated motor speed to 29Hz and default frequency to 29Hz, that will lift the v/f curve and you will get more power up to wherever you hit the input voltage limit... seeing as the motor is in star, you won't be overfluxing, in fact it will be close to what you would get if you were on 415V

Ray

Hi Ray,

Its sure worth a try. I was planning on using a HT800 which doesnt(?) have that parameter, but I have a spare Huanyang.
Its just occurred to me maybe its not the motor, when it starts it gets up to a certain speed quick enough and sits at that speed for "a while" then quickly goes to full speed. Maybe its that belt slipping?

Stuart

Looking good Stuart. Just out of interest, do you have any projects in mind that will use this machine?

Cheers,

Simon

Lol I wish, but I'll think of something

Cleaned up the DRO and put it back on.....Wouldnt be someone with a manual for a Sony Magnescale LM20-21T would there? (lol hows that for a long shot?). Had a google and came up with nothing, though I doubt I'll ever need any functions other than basic X Y and I can do that now.

Been looking at oil also, there are at least 5 oil baths. I only have info on two so far, DTE Extra Heavy(looks like another 20 drum).
Ways a Vactra 2, so I'm good there. That just leaves an oil dripper and well over a doz ball oilers.

Time to get the table off for a clean, they prefer its kept on a surface plate.........
