    Nakamura w/18i /Block Skip

    On my 150, the bar change program has a plain block delete slash in front of it. / M98 P999 The block delete switch is not turned on. This block is skipped every time until the bar feeder tells it to load a new bar. I haven't used block delete for anything else on this machine, so I gave it a...

    Lathe threading insert for getting close to a shoulder.

    Does anyone have a recommendation for a threading insert that will get right up to a shoulder? I'm currently grinding back a 16ER laydown style insert, but that's a pain, so I'm looking for something I can use out of the box.

    Swiss sub spindle OD turning holder

    I'm not surprised that you can't break chips turning with a Micro100 boring bar. What shank size is on your sub holders?

    seeking info on bar feeders for old swiss lathes

    Citizen, Star, and Tsugami would be the top 3 brands to look for. Here's a nice little Citizen as an example. 1/2" capacity, no live tools, bar loader. It's about as basic as you can get in a Swiss. It does have a sub-spindle, so if you wanted the most basic, you'd have to find one without a...

    seeking info on bar feeders for old swiss lathes

    I believe that Lipe made auto loading bar feeders for Brownies. And not all Swiss are 7 axis. You could find a simple, used, small capacity Swiss machine with a loader for not too much money. Just something to consider.

    Brother power issues?

    Thanks. I'd be interested to know what you're using for data logging. It sounds like it could be useful or at least fun to play with. I may be confusing you with someone else here on PM, but don't you have a bunch of 5-axis DMGs? Are you telling me that you run your whole shop off of phase...

    Brother power issues?

    There is a breaker panel between the transformer and the machine. I believe the circuit breakers are Siemens bolt in style, but I need to look. I think swapping breakers is my next step.

    Strange axis feeding issue

    Thanks for the suggestion, Teach. I was going to look into the proper threading setup for the sub, but you already did the legwork for me. I appreciate it. I am going to see if they offer this in a 22 mm shank because that's what Star decided would be the best shank size to standardize on.

    Strange axis feeding issue

    Thanks for the info. Unfortunately, checking encoders with a scope is out of my realm of knowledge. I may need to find someone who knows what they're doing.

    Strange axis feeding issue

    In looking into this, I did just find that I have about .0025" play in my Z. I wasn't aware of this and was quite surprised by how much there was. It hadn't shown up in any other work I've been doing with the sub. Like I said in my first post, I'm mostly just picking off, spotting, drilling...

    Strange axis feeding issue

    I ran one at 1000 rpm, and it behaved exactly the same except for sounding quite awful for a few of the middle passes.

    Strange axis feeding issue

    Sub-collet is plenty tight.

    Strange axis feeding issue

    The belt looks great. I can't see the other pulley, but sticking my fingers up there and feeling around, it checks out.

    Strange axis feeding issue

    I tried machining the thread with a piece of brass. It made a really pretty looking thread, but it still had the same problem with the pitch diameter being up and down over the length. I only made one, but it did seem like the variation in pitch diameter was better than with the 416, but it was...

    Hitachi-Seiki HT23J

    Sounds like a mess. Sorry to hear about all this. On my HT23J, the feed hold button failed so that sometimes it would always be on. Pressing cycle start did nothing when this happened. Check the diagnostic for the feed hold.

    Brother power issues?

    Any suggestion for a multimeter? My old Fluke 21 doesn't seem to have that function.

    Brother power issues?

    Hey Pete. Thanks for checking your machine. This is a pallet machine, and it has the Sanyo drives like my other machines. I think I need to get a multimeter that can read max/min.

    Brother power issues?

    Hi Frank. Thanks for the suggestion. That little control transformer was the first thing I checked. It wasn't set correctly, but adjusting it made no difference.

    Brother power issues?

    I don't think that's the issue here because the same transformer is powering a few other machines including a HMC, but I am still going to check all connections anyways. Thanks for the suggestion.
