    As of right now its been put on hold for a week or so while they sort out if they sent the right print or not... couple machines that are very similar but not, built back in probably the 20's or so in Germany plus poor record keeping over that many years. I should be greenlit on at least some of it after next weeks shutdown.

    Started rough turning the 11" dia round. I think I made about 60 lbs of chips already. Was doing some facing and thought it would be neat to look at it on the thermal camera. The pile of chips and the toolholder are warm and reflecting off the part. The chip pile read over 200 deg F

    Color photo for comparison.

    Got a few stainless chips made tonight. 6.25" dia hole 4.125" deep, next have to run a 6" hole down to about 6.4" Stopped for now as its late and time to rotate inserts on the high feed mill. Thats a 2" Sandvik high feed on a 6" shank, about 8" overall gage length iirc running 0.035" doc, 800 rpm, and .010" chipload per tooth just fine. This will be the first time turning the inserts for this job so not too shabby tool life considering its swimming in chips down in there. Tried to set the coolant nozzles up to create a vortex and it kind of helped but still have to pause every 5 or so depth cuts and fish em out a bit better.

    For size ref the part is 11.5" tall and is sitting directly on the table. 10.5" major diameter. Just trying to take some weight out before I put it in the lathe to finish bore it and this way ensures good chip breaking etc.

    Got the feed pushed up to 0.020" per tooth this morning and finished the hole. Probably could of gone faster yet but a bit nervous with that gage length and that deep in a hole with chip flushing problems etc. But anyway the hole is roughed. Now to put some bolt holes in the end and then move on to some of the other pcs.

    Not to shabby for a Haas with linear ways. Ill see how much harder I can push it on some of the other parts. May also pick up a shorter holder for some of the thinner pcs. And before anyone asks, I did full retract on every cut so it was easy to pause it anywhere and shovel chips out.

    A few more stainless chips made today. Plate used to be 3" thick. Pretty well roughed out now for some finishing.

    Seems like I get about 100 cu inches of metal removal for a set of edges (5 inserts in the cutter). Not sure if thats good or bad, but for 304 I'm thinking its not to bad. Gotta order some more inserts tomorrow though.

    Slowly but surely parts are apearing out of the big chunks of 304. Should be starting the 3rd barrel of chips tomorrow. I miss machining aluminum.....

    This might clear it up a little bit. Just came back from the welder. Got 2 other parts to finish up and a few surfaces to clean up on the weldment and a large groove to put in it yet. All before end of next week... Gonna be some long days coming.

    Did the welder passivate it, or just bead blast it and ignore passivation?

    Why do they need 304 for a wire roll holder?

    It's just sand blasted. Customer doesn't care about pasivating. It's stainless as something about washing dye off with acid. This is on breast roll that get shook back and forth to level the pulp.

    Boring sure is boring....
    1" bar 8" overall depth, boring out to 2.25". I circled milled both sides close first but have to bore to make sure both sides are in perfect alignment. Then just have to push some sleeves in and install the swing arm. Then mill a large groove... And yes I had to go that slow or bad vibrations. If I do this again I will be picking up a cat 40 threaded adapter which would shave about 3" off the tool length.

    1" bar x 8" deep?

    I don't think that a Cat40 Adapter is going to solve any issues there!

    What is that - a 4" head?
    Is 1" the hole size?
    Or could you put a 1.25" bar in there?
    De-Vibe would be good, but if you are only dooing one, slow works fine too.

    Boring was a success. Pushed a couple a bushings in with a little enerpac from the middle and honed out till pin slid though. Had to use enerpac to open it up a little to get both thrust washers in but it is now nice and snug which is kinda what they wanted. The swing arm still swings just needs a lead hammer to convince it to. A few shims in the joint and time to mill a big groove in it and then that piece is done. The bearing housing should be going in the turning center tomorrow as well... fingers crossed this time tomorrow night this job will be done!

    Is it not politically correct to ask what kind of dollar amount is hooked onto a beautiful job like that?
