Hi folks,

I need to machine a washer 2mm thick, 28mm outside diameter, 25mm inside diameter. Any suggestions for this beginner?
 
Grab a piece of tubing bore to the correct ID dia. turn to the right OD grab a parting tool and cut it of 2mm thick. Ray
 
You can also do what iron man suggest with a piece of rod stock, drill, bore to your inner diameter, then turn to the outside diameter. Face off one end, then part off a little thicker than your final thickness. Super glue the rough washer to a faceplate, or a piece of stock you have placed in your chuck and faced off. Face the other side to the right thickness. To remove the washer, apply heat (best to remove your faceplate and do this outside). Take light cuts here, and don't get the piece get too hot, or the superglue will let go before you want it too.
 
I have had good success using hot glue. Same problem as the superglue, watch the heat. Easier clean up than superglue, mineral spirits works very nicely.

Chuck up a piece of round stock, turn the OD, bore or drill the ID and face off the end. Then set your parting tool up dead square to the work and perfectly on center and part off your washer, using lots of cutting oil. Use an indicator to square up the parting tool square if you need to. Once set up you can part off as many washers as you need. Just use your carriage stop, move over the thickness of your washer plus the thickness of the parting tool and use lots of cutting oil. Did I already mention that you should use lots of cutting oil?

If you can't get a good enough finish with the parting tool, get yourself an expanding mandrel, machine a step on the end and hold them by the ID. That way you can face both sides. With that thin a cross section though, the parting tool should work just fine.

Wow a " washer" with a 1.5 mm wall thickness, hardly what I'd call a washer. I would bore ID first, then light cuts to finish OD. Then I would grind a thin part off tool about a mm thick and part off. Not a lot of material here so go slow.
 
THANK YOU ALL
I shall give those suggestions a go.
'washer' was just a simpler way of explaining what I need - I have an old tile cutter for which I couldn't get a diamond cutting disc of the correct bore for the arbor. This 'washer' will centre the discs I did buy on the arbor, without having to modify the machine.
Again, thank you all
 
Use double sided tape to attach thin stock to closed 4 jaw chuck and machine lightly. tape will be the spacer so you dont machine chuck. I have done this on material as thin as shim stock. Just to do it.
 
I am not sure if this is politically correct or they are comming to get me, we do a share of local boat yard
shafts, keys and the like, and here, its quite normal to drill pennys for washers. The thought is, fuel to
go to hardware, find them, sales tax, we drill pennys. Bored a coupling and slit it, stack pennies in it,
mini clamped the coupling and center drilled twenty a time. 20 at 20cents one minute done, no driving,
no fuel and the embossings are great locks (lock washers)
