The HOLY GRAIL of Precision Machining | SIP Hydroptic 6 Jig Borer

Show Video

how you going guys Kurtis from cutting  edge engineering today's video we   are revealing our sip hydroptic number six jig borer a jig borer is a machine that was invented  for the precise and accurate positioning   and centering of a hole this wasn't designed for  heavy milling they were designed for light milling   but to keep the accuracy in the machine they were  really only used for drilling reaming and boring   so i've had this machine in the workshop for  the past nine months the way i come to have this   i was going to newcastle to see my tooling supply  for the first time i booked in a time slot to   go and visit this in person i run out of time  and i wasn't able to go and have a look at it   but i bought it anyway when the machine arrived  i organized a 25 ton franna crane to come in and   unload it from the truck and bring it into the  workshop we got it unloaded no dramas brought   it around to the back of the workshop the crane  operator was complaining about headroom that he   probably wouldn't fit underneath a few things  i was pretty busy that day so i said look just   leave it there at the doorway and i'll sort it  out so they dropped it there and it sat there   for six months the plan was to always have the jig  borer here at the back of the workshop it is the   cleanest area so it gets the least amount of dust  i also had a bit of a hurry up to move it because   the mazak was coming over from where it used  to live i wasn't going to be able to get the   jig borer past the mazak once it was in place  so i used my yard crane to lift it up from the   front of the workshop and i snuck it around the  back of this lathe and placed it right where it   is so now we're going to show you exactly what  this is and how it works this is a sip hydroptic   number six jig borer it's made in switzerland  and we believe it is an early 1960s machine so   the tolerances that can be achieved with the jig  borers is absolutely incredible so a machine that   is 60 to 70 years old you can achieve a tolerance  of 0.001 of a millimeter which for something that   that age that is amazing even in today's standards  with all of our technologies we have with digital   readouts this will be a far better and more  accurate machine than a lot of the stuff that's   on the market today there's not a great deal of  information we have about this and how it came   to be in australia and where it was when it was  here i do know that there is another australian   with a jig borer identical to this one the same  company that imported the machine that he has   also imported this machine probably  likely that the two machines were in   the same facility and if that is true  they were in a government facility   working on jet engine parts so the sip hydroptic  machines they started out being manufactured in   1934 with the hydroptic number one there were a  couple of variants all the way through the series   of machines all the way up to the number eight  the number six was where things really started   to take off and then after the sixers they  moved onto the sevens in about the 1950s 1960s   and that's when the machines became cnc controlled  larger the number in the build was the bigger the   machine i believe the 8p is the biggest hydroptic  machine they built and those machines can weigh   up to 15 tonne this number 6 weighs 8 700 kilos so  8.7 tonne it's 3.4 meters tall 3.2 meters long and   2.4 meters wide table size it's 840 mil wide 1100  mil long to move the table back and forward it's   actually hydraulically controlled so there is a  cylinder underneath that moves a table in and out   the way that you engage the table is there is  a lever here which starts the hydraulic pump the table has four speeds you have three  speeds for doing any sort of machining and   then its maximum feed rate is its rapid  and it will advance the table whichever   direction you point it so we'll start with  the slower speed that's 70 mil a minute and go to speed two speed  two is about 200 mil a minute   go to speed three is 300 mil a minute and then its maximum speed so the travel on the table so that's all  the way out to all the way in is 950 mil the way you lock the table up is you disengage  the hydraulic pump and that automatically locks up   the table from moving in and out and it won't be  able to be moved until you start the hydraulic   pump again not only do you have your hydraulically  controlled feed rates you also have a hand wheel   for your fine adjustments the hand wheel only  works when the hydraulic pump is on and running so not only does the machine have  a scale mounted to the bed you   also have a fine adjustment to make finer  measurements here on the end of the table but it gets finer again so underneath this little  black cover here we have an optical measuring   system it's this measuring system that really set  the sip machines apart from other jig borers of   the same era the way the optics work is when you  are trying to reset a zero or set a new zero or   something like that you've found out where you  want to be on the table you need to come down here   and set a new zero for say a step over or a step  in simply what you do you set your dial to a zero   so we've set our zero here but if you  look down inside the optic the little   fork that's sticking out is nowhere near  any sort of line so the way to set the   zero and move that line across is done by  a little control up here under the table   you want that until you get your line  to fall back in the fork in the optic so the optics we have down here for the  measurements on the table we also have up here   for measuring the head left to right i don't  have a light working in there at the moment   so you can't exactly see what is happening but  it works exactly the same way just so you're   taking out a new zero you'll zero that off  the way you do the fine adjustment on this   like i just showed you on the table is via this  little knob over here so you simply wind that   left or right to reset your zero the way you turn  the lighting on for all of your optics and your   table you have a couple of switches down here on  the side of the machine we can turn on our screens you then turn on your indexes and  you also have a day and night feature   so during the day you obviously run it on day  and you can see the optics during the night it   will dim the light inside the optic to make  it easier to see you also have a table light and you also have a coolant pump which comes out  of this nozzle here there is also a lubricating   system for the jig borer there are three buttons  at the back of the machine that you can push in   and all it does it just fires a shot of  oil into any parts of the machine that   need to be lubricated during operation we  have our lubricating area here underneath   the lubrication area we have the hydraulic pump  and off to the right hand side of the hydraulic   pump we have our coolant tank i haven't put any  coolant in the machine since i bought it i did   fill up the hydraulics and the lubricating system  and that's it the jig borers typically came with   a rotary table as well you could buy them as  an electric unit or you could buy them as a   manual unit like the machine the table also  had very very fine adjustments for achieving   really really tight tolerances this machine did  have one on it it was a totally different color   i didn't think i was going to use it because i had  rotary tables here the guy i bought the machine   from wanted a lot of money for the rotary table  i don't believe it was worth what he was asking   for it but in hindsight i still wish i bought  it to move the head side to side on the machine   there is generally a wheel here which is a rapid  traverse wheel it got broken off at some stage of   its life i'm not sure when that was i do need  to come up with something there to refit that   the other way the the head moves side to  side is you have a knob here which drives   this lead screw which drives the head back  and forward pull that out there are three   speeds in either direction speed one is 23  mil a minute of travel across the machine speed 2 is 35 mil a minute and speed 3 is 70 mil a minute the travel on the spindle across the bridge is  700 mil same as a table the machine does have   its power feeds but it also has a fine feed so  to use the fine feed you push this knob back in   and then you wind it by hand  and it is extremely slow this handle here is the lock for  the cross travel so this handle   must be down in the locked position  in order to use the electric drive   to drive it across you only unlock it when you are  rapiding using the hand wheel that i don't have   the bridge is also power feed you can  lift and lower the bridge by this lever here the travel up is 900 mil so you've got 900  mil between the table and the spindle nose when   the bridge is at its highest point the way the  bridge is lifted and lowered behind these two   tubes on either side of the machine there are lead  screws those lead screws then run up to the top of   the machine into a gearbox and then they're run by  a single motor for lifting and lowering the bridge   the bridge also has a lock on it so it's in the  unlocked position at the moment when we lock that   the power feed does not work so it needs to  be unlocked in order to re-lower the bridge so there is one speed for  lifting and lowering the bridge   the fine adjustment for the height will come from  your quill on the um spindle of the machine you do have a lock here which if we unlock that  we'll then wind the spindle all the way down lock that back in place the length that the quill  can actually travel is 280 mil that was one of   the main reasons why i bought the machine such a  long quill travel is really good for boring some   of the deeper jobs that i do i can do them in a  single pass without having to set up a line borer   and do it like that the movement of the  quill up and down can be either done by hand   or fed automatically by the machine on the  auto feed the way you set it to stop at a   height is after you've engaged the automatic  feed you then rotate this wheel around to the   desired depth you would like to drill the hole  or bore the hole so you set that to say 20 mil   you push these two levers in that are here and  they will start to advance the quill down   once it hits the zero mark on that dial it'll  disengage the quill and stop it from feeding so you also have a fine feed on your  quill so you do that by this wheel here   you also have a dial indicator on the side  of the quill for doing really really fine   adjustments once you've achieved the  height you want to work at you then   set your dial indicator to a zero unfortunately  this dial indicator is ceased so i will have to pull   it apart and try and fix it you can then bring  this up to your dial indicator which is basically   just an end stop zero out your dial and then  you can advance it however far you want to   using the hand wheel on the machine there are six  different feed rates for the quill travel the way   the feed rates work you have basically a high and  a low range you have two levers up here and that   designates which range you're in when you're  in the top range that arrow is pointing at the   0.35 when you turn it to the bottom range it's now  at 0.10 so the slowest feed rate is 0.04 of a mill and the fastest is 0.35 of a mill per rotation

so everything you can do on the with the gears  and the quill travel you can also do in reverse   the same feeds and speeds you can just travel  back up all you have to do is push this lever up so you do lose a little bit of your  quill travel because when this is   in all the way up position that is  how you remove your tool so i can now   turn that spindle so it's unlocked a mechanism  inside to then remove the tool when you come   back down that is now locked up solid so it's  now re-engaged so you do lose 30 odd mil on the   spindle we have 18 speeds we have 18 forwards  and 18 in reverse from 40 rpm up to 2000 rpm so to start the machine you have a  start button over here and a stop button you also have one on the other side of the machine  if you're working on that side of it not only does the machine have a boring and milling function  it also has a tapping function so when you flip   this switch down to tapping start the machine  it'll run by itself but when you want to reverse   the tap back out of the hole you don't have to  stop it you simply push reverse and hold it in so there are a few things i need to fix  on the machine before i'm going to put   it in to service i do have some damage to  my way covers at the front of the jig borer   so it looks like someone's dropped something  heavy on there and they've split the covers   so i do need to fix that i am missing the rapid  wheel off the carriage to move it side to side   i'd like to fix that there are a handful of  bolts that i am missing i'm going to get a   friend of mine to make up some bolts for me  because i just don't have the time to do it   and the bulbs in the optics so once i get all  that sorted out i can then put it into service what's this one what is it i don't think this is for homeless he'd probably have better luck opening it oh it's a knife wow with my name on it fancy very so thank you tim for the multi-function  knife this'll be my new letter opener you're not helping [giggle] oh what is this he can smell it yes right so something else that's really really  cool about this machine that i was unaware of   until i read the book to find out how i was  supposed to lift the machine when i had to move it   from where it was in the workshop to where it is  now i was reading through the book and discovered   that there is a hole that has been manufactured  into the casting in the front of the jig borer in   order to lift it correctly there is a hole at the  back but it is visible without removing any covers   so after removing the front cover to then expose  that hole to rig the machine correctly for lifting   i found something that there is the hole that  you use for putting a big bar through in order   to lift the machine when you're trying to move it  and that's when i pulled that cover off i found this so what all this is these are spare  parts for the electrical on the machine so we have some spare contacts for the  switches for the forward and reverse   oh someone's done a drawing of the switches we've got some spare contacts fuses and a few other spare  parts which i don't know what they are just yet probably not a lot of people know that  those are hiding in underneath this cover   so it was pretty exciting to find them so  not only did we get the original manual   with the jig borer that shows original  specs lengths heights widths weights   pretty much anything an operator would need  in order to use the machine is in that book   we actually got a second one with the machine as  well both books are pretty much exactly the same   there is a little bit more information in the  newer book not really sure why it came with two   maybe the guy who owned the machine or the company  who bought it decided to have a spare one just in   case they damaged the first one and this might  have just been a bit more of an updated booklet   for the machine one of the other books we got  with it is all these schematics of the machine   so it has everything in it from your electrics  to your hydraulics to your gearboxes to   everything it gives you torque specifications  for bolts tolerances for all the different gibs on the machine it gives you everything so if you  want to rip this thing down and rebuild it that is   the book you're going to need one of the other  books we got it's a booklet on angular spacing   which gives you so many different dimensions  that i have never even looked at before it is   mind-blowing that someone sat down and worked all  this out this book is just full from top to bottom   of all different measurements to make whoever was  using the machine's life a lot easier and randomly   in amongst all the paperwork i did find the  actual sales brochures so we do have one for a7p and for the hydroptic number  six so that's pretty cool and we also got a booklet of tooling  and accessories that were available   for the jig borer there is nothing you  couldn't achieve with the amount of tooling   that is available for them one of the best parts  about this machine and the deal we got with it   we ended up getting a lot  of genuine tooling with it so in this tool chest we got a lot of boring  heads of all different shapes and sizes we've got a couple of different sort of  centering devices that you put up in the spindle we've got a few spare parts spare tools like  genuine allen keys for undoing the grub screws   that hold the high speed steel bits inside  the boring heads i'm just going to explain   a little bit about why some of the boring  heads look so different to the other style   boring heads that are here in the box the quill  on the machine the taper in the quill is an mt4 so   morse taper 4 a morse taper 4 in today's language  has an m16 drawbar in it this machine has an m14   drawbar in it so you can't just grab random tools  off other machines and use them on the jig borer   they need to suit the machine perfectly otherwise  they don't work this here is the standard morse   taper 4 with the m14 thread that suits the  drawbar and suits the spindle of the machine so that's the standard one it works off this  of the morse taper itself in order to apply   friction to the spindle to drive the boring head  in order to do whatever you're doing the bigger   boring heads they don't use a standard morse taper  in order to hold the tool central in the spindle   so that all comes down to another style of taper  locking system that is exclusive to sip only as   far as i'm aware the biggest dial has a parallel  shaft on it which is just straight up and down   same m14 thread in the end of it they don't rely  on the morse taper 4 taper in order to drive   them or add support they rely on this other taper  which has the male version on the machine and the   female version on the tool there are two flats  machined onto the arbor itself and they must   correspond with the machined area in the bottom  of the spindle that is also used as the drive so   that just adds a great deal more rigidity  and precision for the bigger boring heads so the way that you remove the tools from  the jig borer is you have to take the quill all the way to the top that will then lock up  your draw bar but it unlocks your quill and   you simply use the big spanner that they give  you to then unlock the tool from the spindle so what comes in this box is all the tools and  the cutting bits for the boring and facing head   unfortunately the box is pretty beaten up  and the boring head doesn't currently fit   in there because it still has a tool in it so  it's an automatic facing head gets put in the   machine like any of the other tools do that have  that big collar on them underneath the support   and this can be used for facing off  something or getting down inside a bore and then cutting a say a snap  ring groove or an o-ring groove this is the extension so you  can reach larger diameters   so you simply unscrew that one and screw that  one back in its place so we also got three   boxes of the optical measuring equipment  that comes standard with the machines   so we do have a center finder here so it gets  put up into the spindle you can then look   through this glass here and center down on top of  a point that you are trying to drill and or bore this is another part of the optics i'm not 100 percent  sure how this one actually works i am going to go   through the book and find out exactly what it does  i believe it is for setting level of the machine   but don't quote me on that this plugs in down  here there are a few parts missing so we can't   actually plug it in to see what it does but that's  just another thing that came with the machine so i haven't actually worked  out what this does yet but i'm   going to go through the book and  try and figure out what it's for i don't think this box belongs in this particular  case i believe it belongs with another one so with all the tooling we also got a box of  miscellaneous stuff there's mainly bulbs and   fuses a few different sorts of little tools and  accessories that probably belong in these boxes   some of these t-handles they suit a lot of  the fixtures on the machine so i'm going to   go through all that and try and piece all these  kits back together so that's all the tooling and   accessories we got with the jig borer i am going  to put this into service it probably won't be for   a while i do have other projects i need to get  out of the way first it's just it was just too   good a deal to pass up considering what i got  with it if i ever do come across the sip number   eight it is something i will definitely do my best  to try and get but for now we're very happy with   the number six it's going to be a joy to work  with this machine being its era and what it is   capable of doing we are also interested in any  of the hydroptic number six tooling accessories   tooling cabinets so if you know anybody that's  had a machine that may have spare parts or you   know of any spare parts or tooling getting around  drop us a comment or send us an email we'd love   to hear from you so we hope you've enjoyed the  walk around of our jig borer thanks for watching how you going guys Kurtis from cutting  edge engineering so today's video   we're going to be revealing our sip hot [giggle] we've sort of figured it out that the  hydroptic means it's hydraulically driven and it has optics [Laughter] made by [giggle] what you can do it you can do it i don't want to say that i might offend somebody   sorcieta genovas you probably just swore  at someone somewhere someone hates me   i'm going to get closer NO don't [ __ ] back up a little bit ready yep you go back to where you were it's fine it's good it's too [ __ ] close do you want to put your arm down   just lean on the side there there you go yep  you want to unfold my arms no that's fine   that's fine i don't know it's history i don't  know who i don't know who i do know actually [Laughter] what why i come to have this machine  is i was in the market for some   i was in the market for a new cn uh not  new i was oh my god oh my lordy lord   save me jesus he can't help ya [giggle] so the tolerances you can hold with the uh [ __ ] i try not to say machine so much yeah that's good because you say it a lot yeah come on words come on why not working it is working it's moving oh my god you then lock it and none of the power feed will work okay   until you unlock it okay right but that's also down  here as well ah my brain [Laughter] okay come back over here you have a leave ah dial oh [ __ ] knob so it's obviously BANG dick head [ __ ] off train [ __ ] off [ __ ] off right so the optics we have down  here on the table for measuring   the table [giggle] we also got a tooling and accessories  booklet from the jig for the jig borer [ __ ] okay   start again right so the other  book uh so the last oh [ __ ] me it just needs to make sense is all and sometimes it's  hard making you make sense okay uh these and eh [ __ ] [sigh] um it's it's one of the oh [ __ ] me what are you trying to say i don't know these were built fff[ __ ] NUH [Laughter] so that's our hydroptic number six jig borer uh   so that's how the and oh [ __ ] we hope you've enjoyed right stop end ahhh oh hi hey oh [giggle] idiot
