Hello everyone, I'm a new user of this forum so first of all thanks to anyone who is going to help me.

In my factory we are trying to improve our working cycles. We produce motorbikes crankshafts, and at the moment our cycle has two phases of turning, then one phase of milling. We are now looking for a machine that could do all the work, and had a look to some multitaskings.

We looked at Okuma Multus U3000, but it's out of our budget, same as DMG NTX.
then DMG CTX Beta 1200 but it looked overpriced for the real quality you get, and looked not very solid. Mazak integerx had a better price but still looked not like a rigid machine.

We have interrupted cut all day long while turning, so that's our first problem. Then we have to cut gear hobbing on our pieces and many other problems. Also, we would need a machine with a lower revolver and sub spindle to be able to do turning and milling at the same time, one on the first spindle and one on the other. Also, we are in a production process so no single piece, but usually between 200 and 3500 pieces per order.

Anyone got any experience or feedback about the Doosan Puma SMX3100? Is it solid and reliable? What about power skiving gear hobbings? And how does it works with repeatability? Can it hold tolerances between +/-0.02mm in a working day of 16h?

Thanks again to anyone who's going to help!
