Hey Guys! I need some help as I am completely new to the Mori Seiki world, I would love to learn about these machines as I have been told they are amazingly high quality and accurate machines. The Machine is a SL3H, can anyone tell me what the "H" signifies? Also It has a Yasnac Control I would love to know if any one can tell me about the control? Is it good, and can I send programs to it via rs 232?

thanks in advance for any help, Im super excited to learn about these machines!
I can't help you on the meaning of the "H" in the nomenclature but my machinist friend has the very same model. He bought it about 3 years ago and it needed some assistance to get going. I helped him out with my electrical knowledge. There are numerous relays in the controls of these machines and we discovered that more than 25% of them were stuck shut. This prevented proper orientation of the tool holder unit. Once the relays were cleaned and working, we discovered that one of the amplifier units was bad.
We removed that and sent it to a place in Illinois that specializes in repairing them. It's been good ever since.
As far as I know, the Yasnac unit is very good. He converts his drawings into "G" code and uploads them into the Mori through it's port, which could be RS232, but I'm not sure about that.
He had difficulties with the 10" chuck that was fitted on the machine when he got it. The 10" size interfered with tool fitment. Then we looked at the manual and discovered that it originally had an 8" chuck which we sourced in the Bay area from a machine seller.
I hear nothing but good things from him on this machine. He has an ongoing contract with a company that uses many aluminum pipe fittings and the Mori produces them very nicely once you load the bar feeder with the appropriate stock.
We also replaced the fans in the amplifier box. One of them had failed and this led to an over-temp shut down on a few occasions on hot days. Two new fans and the problem was cured.
We also had the light inside of the machine go dead and I traced this to loss of continuity in the wire powering the light. Since the wire was inside the frame of the machine, we abandoned it and installed a new light with outside power. Problem fixed.
He bought the Mori to replace a Mazak, which had a control system that he loved (Mazatrol) but he was unable to get any support from Mazak. Every time he called, they sent a man from the Bay area (90 miles one way) and he had to pay for the trip plus work time and the guy couldn't seem to fix the problems. He spent most of his time on the telephone with his office. Several amplifiers failed on the Mazak and no cause was ever found, so out went the Mazak.
All in all, from what I've seen and heard from my friend, the Mori seems to be an excellent machine. I don't know whether you have the manual, but I certainly recommend one. It enabled us to fix several of the problems we encountered and it is very comprehensive.
Good luck!
