16Т02П soviet lathe

[Sonic EscapeParticipant @sonicescape38234]

I found this lathe on sale and I was wondering how it is comparing with a Chinese model. I’m more interesting in precision rather than size.

The headstock is MT0 and it weights 35kg. Here I found more specs. From my research there were 4 precisions classes un USSR and this model is the third best one.

Unfortunately is quite far from me and I don’t want to waste one day to go to see it. What are your thoughts about this lathe?

Looks a bit like a Pultra?

Are you sure the HEADSTOCK is MT0? The pictures on the site to which you link show a collet headstock. It could be that the tailstock is MT0.

For the lathe to be useful, you need to be able to hold things in it. Either you need to find out the spindle nose thread if you only want to use a chuck or you need to find out and assure supply of the collets it takes. If those collets are difficult or costly to find, the machine might not be economic to buy.

That is what google translate says. The seller is clueless about lathes.

I wand to use it only with ER collets.

Typically Russian gear sold on the Western market were good, solid, functional designs but lacking some of the trimmings.

Assuming it’s not been abused I’d expect performance approaching a Pultra so likely to be better than the “priced for a Model Engineers wallet” Chinese imports. Although these days the Chinese import issues seen to be mostly quality variability with good ones being very good. The days of needing full on fettling session before putting into service seem to be long gone.

Do remember its bench lathe with no longitudinal feed which limits the style of work that can be done.

If you are going to use ER collets you will most likely have to make your own collet chuck. If done on the machines own spindle it will be very accurate. But how to cut the threads?

But there are MT0 ER16 collet holders. Indeed, no threads. But the simplicity is what I found attractive. It can be easily dismantled down to last nut.

As Clive rightly says above the Russian machines were good solidly made machines built to a high standard, but not finished to the same cosmetic standard as more mainstream manufacturers from the west. I worked for an importer for a while a few years ago ( early 80’s) and we had a number of Stanko mills and couple of their lathes to check over and install. Electrics were a bit strange but there were no problems with them and some of the buyers made repeat orders. There was also a small 75mm screwcutting lathe almost a copy of the Lorch LAS, and very similar to the TOS MN90 LAS copy.From memory things like the changewheel and pulley guards were a very hard resin or plastic. These machines were of a similar general style to the one in your picture, certainly the graduated dials and handwheels look familiar . These were plainly built but very well made, as far as I can remember only two were ever imported as they took a long time to sell.

All the literature was in Russian, I remember one wag remarking to our boss ” Get me a bottle of scotch guv and I’ll be able to read that after I’ve drunk it !”

It is a pity that it is not the A variant. That is the higher precision version with plain bearings.

According to the interweb, the big end of MT0 is 0.356″, which is well less than the 10.2 mm through bore quoted, so something doesn’t add up
