45 years ago I toured ESCO steels Portland, Oregon cast house. They made huge stainless steel castings for the commercial nuclear industry. Every casting was x-rayed in 3 dimensions to locate porosity and defects. Then, they would have a crew that would grind their way down to a defect, grind it out, then weld their way back out to the surface. ESCOs cast house was pretty meticulous, yet every casting needed repair. So, what you encountered isn't unusual, but, it would appear the company that did these did not properly degas the molten metal, and too little attention was paid to detail when producing the pattern and the casting molds were made. Shame on that cast house.
The worst thing about these castings is that they are small pieces, when you cast 5-ton pump casings in superduplex, these inclusions and pores are not allowed. In the nuclear field we have discarded castings, the Spanish client does not allow subsequent repairs, taking into account that they are critical parts of the reactor.
There are many castings that come with very little material. I still remember a batch of impellers for Chile that, after being finished, looked like garbage. The end customer in Chile never wanted to accept the pumps for the mine because of how bad these impellers looked on the suction side.
cuts pretty much anything but doesn't like corrosive materials. once you burn thru the coating its done for. maby you guys have diferent experiences with it. i like iscar's IC8007 too for some strange materials or welds altho i usually dont use iscar inserts on the bigger machines seco's CP500 is also a great insert grade
I have machined those same spindles here in Indianapolis at my shop for Cleveland-Cliffs. I faced the same issues you did, especially on the max OD. We didn't have to machine the female drive, but I recall needing to cut a groove at the bottom of the drive. We also had to mill the male drive and profile the fillets all over it. Bahr Brothers in Marion, IN made the castings. Turning the male drive OD was a pain in the ass with the huge interrupted cuts. I don't recall the inserts anymore, but we did get Kennametal inserts meant for heavy interrupted cuts. Kennametal also covered the inserts for me to try the FIX-8 tool in the interrupted cuts.
Shitty castings...i really felt that in my soul. i personally love when i hit big voids and pockets of sand when im turning big unstable castings, keeps things fun and interesting.
When you get casting las bad as that, you send the whole batch back to where it came from. When I was helping to build industrial knitting machines, if the bars on which the knitting heads ran back and forth. had to be draw filed and and deburred, and if we found a bar which had loose flakes rolled into the surface, the whole batch was sent back to the manufacturer. to be replaced. We couldn't allow the knitting heads to lift a flake and sieze the whole machine up and would have totally destoyed the whole machine. Our main tollerance was two thousands of an inch.
Hi Chris thanks for this great turning video. What a job to machine these parts that turn like potatoes in roughing but I love the big blue shavings, thanks.
Hi Chris, What a hard job to make this from such rough parts! It looks like the metal casting was done in Pakistan with old scrap metal from old boats... I find it surprising that you agree to do this work from such parts, you work really well, but to make something perfect is really difficult. Well done ! Starting from forged parts would perhaps be better. Even with the first cast wheels from steam locomotives, over 100 years ago, better quality castings were made that required very little machining. Thanks again and congratulations for seeing the work through to the end. Sincerely Xris
Back in the day (nearly 50 years ago now) we found the best inserts to use on crap like this was a PLAIN negative rack insert (nochip breaker etc) with a ~30 deg chamfer. The chamfer provided protection to the actual edge of the insert protecting it from mechanical damage. Great for intermittent cuts, getting thru scale. They could even handle the joint on large gears where the mill had left what amounted to a knife edge facing towards the cutting tip. We used Sandvik tooling (mostly) and we actually had to get them to make them for us for the centre located tooling (like you use). This type of insert was used in the older style top clamp tooling (with thinner inserts). Once we were thru the problem areas it was then time to change back to the more usual inserts with chip breakers and coatings so that we could up the speed etc. I worked on large parts on a vertical borer (lathe on its end) with the smallest pieces being about 3m (9') in diameter the table (chuck) was 7m (21') in diameter, top speed 32 rpm. Funny thing was even though we were an integrated works - castings made in house - we still couldn't get the pattern makers and foundry to understand what we machinists would prefer. Only time we did was a repeat job where we had to set them up almost using a dial indicator (casting was 4.5m in diameter and about 0.250m thick (10")) this slice of potato type of casting did what chips do (it curled) and so we had sometimes less than 3mm (1/8") of clean metal in spots. This along with gassing in the metal that couldn't be stopped meant they increased the casting thickness by 50mm (2"). This gave us easy set up and easy machining. The metal was beautiful, 25mm (1") deep cut 3mm (1/8) feed. Used ~90% power. Sometimes the chipbreaker didn't work so you'd have this 1"x 1/8 metal bar coming off the tool until it got heavy enough and broke off....or the chips where about 75mm (3") in diameter. Really heavy when you had a shovel full..... :)
You have my sympathy Chris, in a past life I've BTDT, .......far too many times, and always with the same answers, ''there's no rime to get new castings'' and ''we mustn't upset the foundry'' Take care and stay safe
You call them spindles, but to me they look like CV slip yokes...either way, someone is building something ENORMOUS and those castings are a fail as a spindle or CV slip yoke. Your ability to produce such a stunning finish while destroying hundreds of dollars in carbide is commendable. It is hard to choose an insert when each revolution includes 3 different materials.
It would test my patience alright....one of them jobs you just got to take yor time and get thru and move on to better things. Great video thanks for sharing 👍
i feel you, once i had to deal with casting´s that were dipped in some black coating for rust prevention our something, there was still sand from the mold beneath the coating and a bunch of air pocket in the casting.
Hrm... core off centre, porosity, rough and uneven surface, parting line wandering all over the place, crappy dressing/fettling... not much attention getting paid in that foundry. Bloody hell... just saw the rest of the abominations... I'd be sacked if I let that trash leave our foundry!
When I saw the first drawing my immediate impression was that someone should break the creators fingers. Woeful would be a compliment. Those castings however the fault was with the pattern maker. Apart from the sag and undersize of the casting the filter broke apart during the pour and I would guess that is the sandy stuff you found in the metal. Sand does break away during a pour but it usally just floats out or mixes a bit more evenly.
Why is the quality of these castings the fault of the patternmaker ? - Surely the fault lies with the moulding/casting shop and the quality of the steel used in the creation of the castings ??
@@NormanGnome11 If the casting is to small not enough material it hasnt been made to the correct size or made for the wrong material. The molders are also at fault as sag, inclusions is very much related to how the mould was built. Coatings, proper sands, risers, shrinkage, and filtration of molten metal all their responsibility. Open the box to early even the way it was cast can affect the shape. The steel doesnt get lighter as it gets hot yet it is a lot softer. It needs support whilst molten and soft. You could blame the caster for the filter problem by putting the metal in to fast but if the mould is built correctly it shouldnt be a problem.
All foundrymen blame the Patternmakers. I see several problems, least of which was caused by the pattern. Foundry first. What kind of sand was used. If it was just greensand the gating looks like it may have pushed the core. Airset sand would be better. Setup is like concrete. So improper molding and gating. Machine shop, if the center was established by using the cavity walls, and the core had been shifted. You'll start out off center. The core print needs clearance to be set in a mold. Never use a cored surface to Setup a part for machining. Porosity is a gating issue and possibly core shift when poured. I've had molders file a core because they didn't think it would fit. But they didn't even try. But Patternmakers do rarely make mistakes.
@@roscoepatternworks3471 OHHH everything said is correct except the mistake part. Why It's easy to just go by the drawing but the casting is variable and its a common thing that patterns dont allow enough clean up for machined areas if there is not a perfect mould. Unmachined areas need to be accurate but machined dont. As a machinist A casting that only needs setup on unmachined areas and extra machining on machined areas is preferable and improves the yeild. But i did mention that the original person who drew that drawing needed their fingers broken. Also the original casting setup needed a bit of adjustment . I have machined to many complex castings when I first started out and it always a game to find the overall best way to set up to achieve the finished part. You basically cant ignore drawing datums but need to ignore them to achieve a useable part if indeed there is one that can be machined from the casting.
@dazaspc the one thing I didn't mention was communication. The Patternmakers rarely decides on how much machining will be required for a casting. The foundry, machine shop, engineering and patternmaker should collaborate on the correct amount. The ultimate decision is the foundry based on their experience. As a retired patternmaker, I noticed there seems to be a trend away from communication. Ps. If the draftsman had all dimensions required, why break his fingers? The draftsman will only identify which areas are to be machined. Not included in the drawing is the amount of machine allowance.
W O W. Holy mother of God, I've had some really shitty "chilled cast iron" components with inclusions, and one that exploded on me, but those pieces of crap must have come from China! Now we all understand why there are no more European pattern makers left 😵😵💫. Well done to you for getting as far as you did. Me, I would have refused to machine any more of them! Cheers.
Do you ever get clients who bring in components with imperfections like these, who end up trying to blame you for the imperfections when machining is completed?
Mostly I'm curious what these things are for. They look like they are supposed to be stacked/fitted together to transfer rotation, but for what other machine?
See what you do here is add a surcharge as close to exactly equal to the savings the client attempted to earn by Not Doing It The Right Way. Those money chips were cringe!
Customer supplied or did your company supply? If customer supplied then they get what they get. If they are yours then the big boss man has some ‘splainin to do.
I'd be ok doing this on the clock like old times for a boss who decided to take on such ugly stuff, but wouldn't bid on or touch this in my home shop. Mat'l being SOS is not the problem of the machinist when the the print is one's backup/'protection'. btw, Inserts kicking butt on those interrupted cuts. Good watchin'! 10/10 as usual. 🙂
They were really trying to get a silk purse from a sow's ear, weren't they?? If the customer doesn't like the outcome, tell them to call the foundry and have them recast the order, on their dime.
Is this piece‘s quality control (or lack of) worthy of rejection? I know cast steel can’t usually be welded on successfully, but I’m seeing as you turn this piece that it’s up and over 1+” out of round/spec. So how bad can it be, before it’s not good enough?
So my company orders extras of a certain casting because they know it will have some that won't make it through because porosity, somebody is either stupid or getting kickbacks........
At such a mass of material that need to be chipped away why dont you use a fully round insert? Im quite new to lathework but from my perspective it would withstand that bad casting better and break less inserts on the roughing passes.
Time to refuse them and send them back. . not worth keeping. The likelihood that there are errors/faults inside that cannot be seen (short of imaging) then they're just a danger, prone to failure. . Send them back.

I think the question as to whether there were too many voids depends upon what you specified when you ordered it.
"Pffft! I know a guy who can do it for less than that!" - Customer
no problem with stringy chips when the porous material breaks the chip 😆
These Th1000 inserts are a life saver when needed. Even used on monel and the hastelloy C.

Seco TH1000 is an amazing grade of insert, I've used it to get out of a couple difficult situations. Haven't found a metal yet that it won't cut
Used on Ht 455& 465 sst. Works wonders when all else fails.
cuts pretty much anything but doesn't like corrosive materials. once you burn thru the coating its done for.

Do the castings warp that much or is it just a bad mould? Also it looks almost like they welded the defects with hardface lmao
