Arc Lathe Collet Chuck and Warco WM180 lathe

[David CambridgeParticipant @davidcambridge45658]

Does anybody know if Arc Euro Trades ‘ER25 Lathe Collet Chuck – 100mm Dia – 72mm Register’ will fit on to my Warco WM180 lathe (without modifications)? Reading the description is sounds like it will, but I was wondering if anybody has tried it?

I would suspect like most of these chucks that you have to also buy a backplate and machine that to mate the two together so as long as one side is machined to fit the flange mount on your lathe and then mounted to it fiollowed by machining the 72mm register than it will fit like a glove.

You can use a raw backplate casting or Warco probably do part machined ones that will just need the 72mm short spigot doing.

It seems it will. Warco sell the same chuck by the looks of things, under the ACCESSORIES tab of that lathe.

I am pretty sure it will fit . Ring up ARC and they will tell you for certain.

Warco paper catalogue also says that a backplate is required

Hi, Arc's ER25 C/chucks come in three different sizes, Warco's seem to be just one size which appears to be the same size as Arc's biggest one. As jason says Warco catalogue says you need a backplate to mount thier own one, to fit on the WM-180, which is unmachined.

I bought a ER32 one from Arc and fitted it to my Warco 220 lathe which has a similar size chuck and I needed a backplate for that, made my own out of a thick stel blank that I had.

Regards Nick.

P.S. just looked again at Arc's and it seems the 100 mm may fit, if your lathe has a 72 mm register, but it may be prudent to turn tour own register for accurate concentricity.

Just check your register it's part of the spindle on these lathes and you should be able to bolt straight on .

I just happen to be sitting here caressing(!) what appears to be that exact collet chuck and a 100mm Myford backplate that arrived from Arc Euro yesterday (plus a ball bearing collet nut).

You need to cut the register in the backplate and, if is is the same one, 3off 8mm clearance holes on a 84mm PCD – and supply the 8mm bolts yourself

Seems good quality components but I've had to take about 0.050" off the thread (in the backplate) from the inner end of the bore as it was stopping the backplate going right back onto the face of the spindle register. The plate was about .002" off round/centre on my ML7, but now it's bob-on after a small skim and a polish. Cutting the register tonight….

Hello David,

Looked at the Warco WM180, and noted that it is fitted with a 100mm chuck. 'Most' Chinese origin 100mm 3-Jaw Self Centering chucks have a register of 72mm. This is general Chinese standard. So in theory, ARCs ER25 Lathe Collet Chuck -100mm Dia, – 72mm Register will fit in place of the 100mm 3-Jaw S.C. chuck currently fitted to your lathe. Best way to be sure is to remove the chuck and measure the register. If register is 72mm, it will fit.

Ketan at ARC.

Thanks Ketan (and everybody else) – I’ve just ordered the chuck from KetanArc.

My collet chuck from KetanArc arrived today – fits on my WM 180 like a glove! As usual great advice and fantastic service form Ketan.
