War o wm18

Its the new avatar its gone to his head 😳

OK so I forgot about this problem as the weather warmed up. I cleaned all the tapers i use on the milling machine and the bore itself. The problem seems to have gone away for now.

Trouble is it does not end there.

I was running at top speed milling some bronze the other evening and the speed counter stopped working. Before i start dismantling the think has anyone else experience this problem?

Is the speed calculated via the drive or is it a counter of some sorts on the spindle?

Hello Bri,

I had the same problem on my Weiss.

Look under the cover at the top of the spindle. There is a plate which runs through a sensor.

This became contaminated with grease. Gave it a clean, and it worked as it should.

I could send a photo in the morning, if that helps.

Hi Daniel. I will have a look. It was vibrating a bit. It might have worked loose.

Cheers

I removed the top cover but there is nothing hiding in there.

I also had a look in the control box, there is a ribbon cable that goes from the digital display to a small circuit board and that looks ok?

This is the circuit diagram that came with it.

No signs of a tacho?

Hi Brian,

Can you post a photo of the top of the spindle ?

With cover removed.

I'm watching this space.

HTH,

Daniel

ERM i put it all back together there really was nothing. Just the motor and the casting top!

I think its generated by the filter somehow?

Bri

Just spotted that there is an induction head, maybe that's something to look for by following the wires. Too bleary eyed now and enjoying a Dads day beer

Will try tomorrow

Hi Bri,

I would remain convinced, for the moment, that the tacho reading is more dynamic.

Can you post some photos of the general gubbins ?

Hoping to help,

ATB,

Daniel

Hello Daniel,

It looks like you were correct. The motor is mounted on a plate and underneath is the disk and counter unit.

Running at high speed has sent all the grease outwards and into the unit.

Thanks for your help.

Brian

On my WM18 I altered the position of the counter unit as in photo. Mike.

Thats a good idea Mike. I will probably do the same to mine.

For now i am up and running again.

Cheers

Bri

Putting a cold arbor into a warm quill would cause this problem. As the quill cools, it shrinks onto the arbor.

Probably already said!

MT tapers don't need a lot of end load to grip. Too much and they do become hard to remove.

Howard.

Great news Brian.

Glad you got it sorted.
