Hi Andy,

I have made module 1 gears cut to full depth in one pass. I don't think your Centec should have any problems cutting the gears required. Using the horizontal spindle might provide a better setup.  What kind of material are you using for the gears?

Cut them in one pass, anything else just wears the cutter for no benefit. I've cut 5DP gears in cast iron and 6DP in EN8 in one pass, and 2 thou per cutter tooth chip load, without any problems.

Ah, finally a Leinen owner here! (although it's a LZ4S…). So we are two, almost a crowd then.

My example was missing the (quite important) 90 teeth wheel, so I went the easy route and bought two standard gears, bolted and loctited them together and turned down to the thickness of the others – 15 mm you say. I'm sure one of the thinner wheels with a hub would be sufficient also.

Btw I use small polyurethane vee belts and a set of pulleys for the feeds – much more silent than the gears!

Bit OT, I know

Hi Andy, my Leinen has roller bearings. I often think they would need just a little bit of adjustment, but I'm not able to understand how to do that. Also the two-speed clutch is shot and works only on the high speed side. Ah well, the oil in the headstock and especially the apron has the habit of disappearing very fast…

But nonetheless this lathe can still do precision work.

Not in UK, Switzerland it is…

Fired by curiosity, and a lust for good machinery … I've just found this discussion, which looks to have some useful links.

Andy,

Many years ago, I worked at Kodak in Stevenage, and we often had to work with technical documents from the German factory. Once you get the way they construct technical words [which is simply by stringing together a series of smaller words] it is surprisingly easy to translate.
