Fairbanks Power Hammer Cross Head: Part 3

Abom79

236tn visningar28

    The next machining op for the Fairbanks Power Hammer Cross head. After finishing the split, I rotated the part around 90 degree so that I could machine the top and front face in one setup. I had enough footage here of the horizontal slab milling to keep it in its own video. Next video I will show using the large face mill in the horizontal spindle to machine the end face.

      Climb mill for a better finish.

      1. Russ Andrew

        Since this is a casting he probably prefers to conventional mill because the cut path starts beneath the surface of the part. With climb cuts, the tooth has to break through the cast surface repeatedly. Although this is only a concern for the first pass.

    3. Edgar Bergeron

      Loving the slow mo shots.

    4. Mohammed Riyaan

      too much talking.

      1. Michael Boyd

        Nose the grindstone. Time is money. LOL.

    5. ARIFIN LATHE

      Very awosome..🤝

    6. Redspeciality

      I didnt quite understand your calculations for the cutters surface feet per minute. Shouldn’t Pi (3.14) figure in it somewhere?

      1. emislive

        Going from a diameter measured in inches to surface-feet explains the first "magic" number: 3.14/12 = 0.262 The second is going the other way: 12/Pi = 3.82

    9. anxiousdog

      21:22 I'm not a machinist and I'm trying to understand why the z-plane is being measured horizontally, shouldn't this be measured vertically? I don't think the horizontal measurement would make any effect as the cut will be done on the x-plane. A vertical measurement on the z-plane would make more sense.

      1. Michael Baker

        It could be that horizontal mills work in the same coordinate system as a lathe. You are right though it is kind of weird.

    10. Ordinary Miracles

      Why did you change cutters rather than going with the final cutter only?

      1. Michael Baker

        You can hog more material off with the cutter that has chip breaks and probably a larger radius on the cutting edge.

    11. TooManyTrades

      Cool slow motion shots, nice addition. Thanks for your videos Adam!

    12. s

      It always looks like a climb..

    13. Heron von Tremonia

      I know, it's irrational. But whenever i see a horizontal mill i got the feeling of being watched.

    14. Ronald Youvan

      The "A" roll camera looks great, but the "B" roll camera or the light used with it are of a dissimilar color temperature, (adds an amber hue) not commonly seen these days, other wise very good video. Ron W4BIN

    15. mpetersen6

      I know the milling cutter is a roughing cutter but the darn thing sure looks like a gear hob. I like it the mill is a K&T. A nice solid piece of iron.

    16. chris denisovs

      Question. Does the center of the bore have to be centered between those two flats? Your video content is top notch. I am a machinist and cut metal everyday but can’t stop watching this channel. 🇨🇦👍🏻

    17. whearywulf

      this video was an absolute delight to watch. thank you!

    18. James Connors

      The chatter you spoke of must typically be mediated per instance.

    19. KB9OAK

      Not sure why, but I find the sound of machinery running soothing.

    20. Steve Corcoran

      Ha, guess you know that you are slightly OCD when watching Adam vacuum up the chips is almost as satisfying as watching the milling operations. A clean shop is a happy shop : - D.

    21. 486 DevilAngel

      그렇게 까지 할필요 없는 작업이야 여러장비를 쓸수 있다고 할수 는 있지만 그렇게까지 할필요는 없다고봐 다음 작업때문에 공구 를 교환 할수 는 있지만 한쪽면 가공하고 다른 면 가공 하고 호리젠탈로 교환 하는게 맞다고봐

    22. Mateusz Haba

      That slo-mo action at about 8:00 was dope. You should put more of those ;)

    23. John Morton

      Really like the transition to slow motion and back to real time it came out really cool like to see more of it 👌 😎

    24. Javier Aviles

      Many different things that you can get the job done, and different ways to do the job . Great knowledge and well maintain shop .

    25. D.mushroom Hunter

      Wow every tool you pull out is another two or $300... They don't sell that s*** at harbor freight....Fun to watch, but extremely hard to wrap my head around how much machining operations should cost!! I can only imagine how much money you have in cutting tools that you use once a year.?? I watch about seven or eight channels that do a lot of machining and nobody truly expresses how much money it takes to have a full setup! Even Adam Savage has been doing it for 30+ years and can't do an eighth of what you can,... he still says he's got more than a hundred thousand dollars in his equipment!!

      1. D.mushroom Hunter

        @Michael Baker I absolutely couldn't agree more! harbor freight is for disposable tools... Actually the only tools I buy at harbor freight I plan on giving away when I'm done with them! but they do pretty good to get you through a project if you have to! As a matter of fact I forgot my crown stapler and it was cheaper for me to go to harbor freight 1 mile away rather than drive an hour to go get mine... It was $29 (I absolutely can't wrap my head around how you make a crown stapler for $29) about 6 years ago it cost me $15 to mail a letter and 2 lb of beef jerky to my nephew in South Korea.. the gas to go get mine would have cost me about the same as the crown stapler. Plus losing $60 at our hourly rate! All that being said in absolute truth and lightheartedness the entire scenario would cost about half of a 4-in fly cutter that will last the entire career!

      2. Michael Baker

        You would not want to buy something like that from Harbor Freight. Chinesium is not your friend in the real machining world. You pay for what you get.

    26. jonka1

      Lots of interesting aspects of set-up were talked about but at no time now or in previouse episodes has Adam mentioned ending up with the centre of the bore in register with the two flat machined surfaces. Could it be that this is not critical or am I missing something here?

      1. Steve Corcoran

        Guessing it is probably not super critical in this application since the crosshead is just clamped around the drive shaft and the pitman arm that actually drives the hammer head is fitted with bushings on each end, so there is a pretty decent amount of acceptable play at both of those points. However, I believe he did adjust the crosshead along both axises in the chuck before he machined the bore for the shaft, so I am guessing he was within 0.001-0.002" after that evolution.

      Thumb up nice teacher

    32. Oleran

      Thanks for slowing the video so we could see the direction...even though we could see the shaft direction. It was odd to watch at times.

    33. Michael O Riordan

      silly question time. why is he milling up out of the work and not down into the work?

      1. mpetersen6

        Climb milling would have a greater tendency to pull the work. Plus you ne er climb gut in a horizontal mill.

    34. robbie !

      Those cameras always make it look like it's climb milling.

    35. Kobwo1

      75 surface FEET per minute? So in one minute it should mill 75 feet?

    36. scrapbmxrider16

      Adam where did the .262 come from

      1. Mike Williamson

        pi x 1/12 foot, i.e. to bring the units to feet and allow for the circumference of the cutter

    37. Hans Packer

      You are a great explainer!

    38. Pushparaj J

      Life is beautiful when you want it to be 😒

    39. Paul C. Sachse Jr.

      Sounded like your servicing cutter was orbiting....?

    40. 2A 3B

      Doesn't removing that much material sacrifice some structural rigidity ?

      1. Doug Bourdo

        Only removed material to bring it to original spec

    41. Michael Martinez

      Don't know why but your videos are very soothing. You wouldn't think so with all them machines an all. Maybe it's your voice.

    42. Ivan Waupoose

      Man I miss those manual machining days.

    43. Bob Engelhardt

      What happened to the posts that linked the video from August 2020? It showed the shell milling of the inside face of the cross head. 6 months ago! Time warp?

    44. Tim Hart

      I noticed in the slomo the cutter looks a bit magnetic and picks up some chips. Does this effect surface finish?

    45. J Boos

      Gut weiter soo!!

    46. gib666

      7:55 Machining porn at it's finest!

    47. Lisa Turner

      Any reason you use the horizontal shaft over a fly cutter?

      1. Michael Baker

        Probably because that was the right sized table for the job. He also said he was going to clean the back side of the hole in the same setup. Less work passes too.

      2. Derrick

        I was thinking the same thing.

    48. Don Petrey

      I see another chip of the month award with that slow mo work

    49. kswiorek

      What happened to the mill table so it has this large "trench" in it (you can see it in 0:32)? I can't imagine any tool that could make this by accident

      1. Oleran

        @kswiorek Oh. Yeah. I see it now. Thanks! I was looking at the work piece.

      2. jonka1

        All you need is autofeed and an operator who isn't paying attention.

      3. kswiorek

        @Oleran I think the edges are too sharp for that. It probably was a large endmill in horizontal mode and someone really didn't pay attention

      4. Oleran

        Is that a result of the cooling speed when the part was cast?

    50. Andrew Operacz

      1. Richard Raucina

        Whole foods. But what a new world we live in when this guy becomes a recognizable star of metal cutting. Better than the Karzhakian bitches for sure.

      Excellent....Thanks

    61. Craig Miller

      Love the slo-mo segments! I have really learned a lot from you Adam. I especially like your setups and lessons on using the indicators. For a hobby guy new to it, it's very fun to see you work and hear your tips. I guess if I had one request it would be longer episodes. They are over much too soon then I have to wait for the next one. :0) Super Nice job!

    62. bcbloc02

      I enjoyed the slab milling!

    63. John Roberts

    64. rik4010

      Nice set up you made and satisfied machining, also wonderful slow mo's...top👍

    65. Vojtěch Prošek

      U can achieve a better surface finish with down-cut milling instead of ordinary milling...hope my english is understandable Im european...Czech...machinist...really like watching your work but im struggle with empiric system... whatever....nice work

      1. James Shaw

        @Richard Raucina Probably the best reason for our continued use of the Imperial system is the well built machines such as Adam has. They were designed to use inches and fractions. Modern equipment can, and often is, designed in Metric. I'm a Physics teacher and don't use Imperial at all. Everything we measure and use in the lab is metric. However, I don't think it's that difficult if you need to use Imperial system like Adam does, keep practicing and using your head and you'll figure it out.

      2. Richard Raucina

        Slovak American here. Yes, many struggles with foolish USA system. At least break the inch into thousandths and then it is not so hard.

      3. Craig Miller

        I'm from the USA and trust me, we struggle with it at times too. Metric is so much easier. Switching over to metric was talked about many years ago but it never seemed to take off. I was in the medical profession and metric is used there. I would convert over in a minute. I use it a lot on my own.

    66. PeppersGhost

      loving the complete waste of Time :-) In a production situation i would slap this down in a vice and run a sandvik Coromill R345 and do this cut in 10 seconds. But yeah always nice to see oldschool how we learned it..

      1. Richard Raucina

        Indeed, this is archaic but of interest

    67. darrell phelps

      very satisfying indeed-

    68. Scott Lee

      It is just simply beautiful to watch those chips fly in the slow-motion!!!

    69. ElJayGee

      Thought something went wrong and the machine was bogging down! Fancy edits there

    70. Alan Roy

      Why not use Pi.? 3.14159 to do the math?

      1. arfon jones

        3 is a good enough starting point. The skill comes in finding the sweet spot for the particular machine,material,cutters and setup etc

    71. dinopug

      Why is there a hole in one of the teeth on the finish cutter?

    72. pdc023

      On the roughing mill, was there a formula you used to come up with the 0.002" per tooth chip loading number?

      1. Larry Robinson

        If you would like to talk about that, please private message me on my SEprom channel or Facebook messenger or email, I would be happy to help. thanks.

      2. pdc023

        @Larry Robinson I'm nowhere near as qualified. I recently retired and bought a hobby level lathe and mill (Precision Matthews) to learn on. I'm learning as I go and loving it.

      3. Larry Robinson

        @pdc023 Great, I'm a fairly new production machinist at a aircraft manufacturing plant and one of the very experienced CNC machinists there told me that info, I like to run at around .003-.004 IPT (thousandths per tooth) most of the time which is pretty conservative actually.

      4. pdc023

        @Larry Robinson Thank you. That's what I was looking for.

      5. Larry Robinson

        IPT= IPM / (RPM x Number of Teeth)

    73. Cliff Burridge

      The arbor says she’s conventional, the cutter looks climb! 🤪

    74. G W

      Hey Adam , I know you don't need flood coolant on cast Iron . But will it help on the finish when making your Last Finish Pass ?

      jeeves my friend dad its a high iq man he added old tent in lathe with magnets and after he has made cuts so he just pull it in every korner and all metal shavings stay in that tent pack then just put all in metal trash

    78. Ernest Storch

      If you ever need the hog mill or the plain mill sharpened contact me and I will do it no charge. I will do them both correctly. The plain mill will be true to the bore and straight with in .0005". ( .00025 per side)

    79. Lee Roy Holloway

      When your video ramped down to slo-mo... I winced for a second at the thought that the mill had took a dump.

    80. Walter G

      Adam, Do you have to worry about the chips that the cutter is picking up as it makes the cut changing the surface finish of the cut?

    81. sbcncsu

      Love some mid-week machining.

    82. OKIE CHOPPER

      Could have this also been done on the shaper?

      1. Finnrock

        I don't see a reason it couldn't. It's a flat surface with plenty of clearance all around it.

      2. Ben Aguilar

        I'd also like to know this.

      _"Kind of satisfying to watch, isn't it?"_ That's why we're here... 😊

    87. John Catt

      There is something so satisfying about watching cast iron being machined.

    88. Raman Shah

      Couldn't help but figure it out: 0.262 comes from pi / 12. The other number - that 3.82 - is its reciprocal, 12 / pi :)

      1. rob hanson

        Thank you! I was wondering where those two figures came from and was about to ask, myself.

      2. Finnrock

        @Bbonno the 12 converts feet to inches, and as Raman Shah said, pi is for converting diameter into circumference pi * diameter = circumference circumference * RPM = surface inches per minute surface inches per minute / 12 = surface feet per minute so it all works out to pi * D / 12 = SFM and of course, if your going the other way: SFM * 12 / pi = D

      3. Bbonno

        @Raman Shah thanks! I had never seen 12 being significant when doing math on circles, and I've never done conversions within the imperial system. Glad you're here to help!

      4. Raman Shah

        @Bbonno Partly! The pi is universal - it turns the cutter diameter into a circumference, which is the relevant thing for the surface speed. The 12 is an imperial thing - turning the inches (in which the cutter is measured) into the feet (in which the surface speed is quoted)

      5. Bbonno

        Why is this done? Is it an imperial thing?

    89. pooinyourass

      You should do a runout? video test if you ever do mount a cutter with a piece of trash on the shaft/taper or even mounting a chuck and show how far something can be off from a chip
