A huge advantage of keeping the trapezoidal thread on your Z-axis you may or may not have considered is the passive holding force provided by friction. I worked at a company that had a few very large, very old CNC machines that used ball screws on their Z-axis but didn't have any form of power off breaking. If the table was not parked at the bottom of its travel and the power was shut off the z-axis would come crashing down with enough force to damage or even destroy the machine! The last thing you need is 200+lbs slamming to the floor without warning!
@russcole56854 жыл бұрын
Very good point, nice safty warning for all. I think as Tony said, the trap thread should be fine as held buy gravity always in one direction, no back lash until bevel gears wear
@h2o2go1414 жыл бұрын
@@russcole5685 I agree, the main disadvantage with trap threads excluding backlash (managed by gravity in this case, like you say) is max speed. That said, I personally have never had the need to move a tool very quickly in the z axis. I wonder if Tony intends on adding a spindle encoder. Maybe a ball screw would be better suited to rigid tapping? Otherwise I don't see any reason to mess with what currently works.

@@bullzebub eventually the company had breaks retrofitted onto the older machines. Unfortunately you can't just use regular hydraulic breaks because they require constant hydraulic power to maintain their grip. It ended up being quite an expensive overhaul because they needed specialized breaks that could activate automatically as soon as electrical or hydraulic power was lost. They also had to activate almost instantly to prevent the head from plunging a tool through the table if the power failed during a cut.

I was 9 years old when watched my Grandfather was moving a new, and very hefty, milling machine into his shop. I learned many new words that day. Of course, I was not much help at that time. Especially when I asked him why he didn't take the machine apart and move it in pieces. His kind and wisdom laden response: "It would likely be easy enough to take apart.. but... not as easy to put back together. Overall, just easier to move it in one piece believe it or not." Looking at what was presented here, I can see why he grunted that thing into the shop in one go. I look forward to an entire series of TOT videos on the re-assembly of this masterpiece of German engineering. :-)

Hi Tony, Long time watcher, short time commenter. What you've produced are some of the most informative, entertaining, and humorous videos out there on KZbin. Speaking on behalf of some of the "hobby machinists" in my local community, we would like to thank you for the scope and detail of your videos, and the ever-present insights across several different, well-developed skill sets, (machining, welding, etc.), that I see are often missing from today's up and coming tradesmen. Your videos have inspired me to spend a small chunk of my retirement on a benchtop lathe and mill. (TIG welder is next!) After spending several weeks learning my machines, struggling with the math, and butchering several pieces of stock, I finally started turning out some good projects. Then all of the sudden, all my retired buddies have hit me up for custom motorcycle parts, broken exhaust stud removals, gun sight mounts, etc. etc., and suddenly, it appears that I now have a great part-time, post-retirement job that I love! Mahalo for all the great videos! Sincerely, Bruce P.S. Please thank your wife and kids too for supporting you in everything that you do as a husband and father.

I worked at a woodworking factory when I was young. Machined molding used in doors, floors, etc. Our big diamond fitted cutters were called hydrolocks because they fitted snuggly on the motor shafts. Then you attached a special grease gun to it and injected grease at high pressure to lock it to the spindle. I think it took 300 bar, like 200 ml of grease to expand the metal in the diamond tool to fit completely to the spindle. Grease gun, yes hand pumped at 300 bar. No electric pumps allowed. Fun times! Best job I ever had. Good money for working 4 days/week. PS. Yes Germans know how to build machines properly.

Finally! News about Maho. I have been wondering about your choice servos vs steppers and I my opinion servos are the only possibility. I have built 2 conversions and 2 new custom machines so far and I think the most valuable lessons I have learnt are: 1 - Gravity: it does not fail you, everything loose will come down in uncontrolled manner, so a motor with brake or external brake is a must on all vertical axes. I also consider a adequate brake resistor a must on vertical axes, otherwise you'll risk frying the drive at the end of high rapid down. (I fried 1) Installing servomotor axle facing up is asking for trouble: the seal is a dust seal, it will not hold cutting fluid/oil. the fluid will eventually get inside, run alongside the rotor onto the lowest point which is the encoder, in most cases with optical commutation track, messing up the motor commutation causing drive to fry the motor (I fried 1). Same with all cables; unless you use connectors for submerged operation loop all cables so that the connector is not the lowest point. 2 - Voltage surge suppression. All coils must have surge suppression - A relay/contactor driven coolant pump is a coil in itself :) (found also this out the hard way) Big Thumbs Up

Hey I'm robotics PHD and: I think there is no real reason to change this thread unless it gets heavy wear after some time. Even then I'd rather make perfect copy than try ball screw. 1st of all ball screw have higher steps. You would get probably like 3 or 4 times higher speed off the same rotational speed, and thus need better gears. 2. If the milling machine never jumped while milling it means the weight on Z axis is always enough for the work. 3rd and most important, this screw not only powers the movement but it also supports all the weight and reducing the size of the core is a bad idea for sake of safety and tolerances. If u need help with CNC feel free to contact me. I've done some conversions in my life, not etherCAT tho. Love ya!

@georgedennison33384 жыл бұрын
@Mad Robot I just told Tony about a zero-backlash nut & screw I have. I bought a bunch of stuff from an engineer retiring due to health issues, and this was in a box of misc. I have seen some anti/no-backlash nuts, but nothing designed like this one. The shaft is ~22 mm and is trapezoidal thread. The nut is some exotic looking metal harder then heck. I described it as looking like it is machined and anodized steel, (I don't think that's possible.) The engineer did high end design and prototype work for the high tech industry here in Oregon. All of the components I got from him were high quality, (expensive) stuff. Lots of brand name stuff, so I have no doubt this lead screw & nut I got are quality. It has the look of quality. The nut has one half with internal threads, which telescopes inside the other half. The 'inner' nut has longitudunal slits, so its threads will tighten on the shaft. The 'outer' nut has a spring wrapped around its mid-portion which squeezes down on the inner nut. (not sure what type of spring that would be. It's not a compression or expansion type spring. wrapped spring?) The anti-backlash nuts I've seen use a expansion type spring to push two internally threaded 'half' nuts, apart, to eliminate the backlash. This ring any bells for you? I doubt he'd find one to match the thread of his shaft, so it would be new shaft and nut, or make one like it. The compression sping type wouldn't work on the vertical screw. If you don't recognize it, perhaps you could point me to somewhere I could look at some, I might find it. Terminology, specifically the correct name, is the biggest challenge I run into when I'm trying to ID/source unfamiliar components. If there is a correct name for them, just that would be a big help.

I disagree with #2 only because this machine used hydraulic brakes to keep the other axes (axises? axees?) from moving. In other words, the weight of the head plus the hydraulic brake was enough to keep the head from jumping during a cut. IF TOT is trying for a full 3 axis machine, and if he is perhaps wanting to heavy rough steel, the weight might not be enough. At least, I wouldn't risk committing to a build based on the hope that the weight is enough. Chances are he will have to settle for 2.5 axis and leaving the fixed nut and hydraulic brake.

Consider that this machine could not do 3d profiling. If you are ramping up or down on a counter the loads are much different and the cutter could bounce on the Z axis backlash.

Also, the leadscrew with a tighter pitch will require about the same torque as a ballscrew with a courser pitch because there is far more friction in a leadscrew.

A local scraping expert (Of whom I am an occasional student in the art of machine tool restoration) told me the short sides of machine tool slideways usually wear from the outside in in this way. If I had to guess why I'd say it's because the slides need some amount of running clearance in order to move, so whenever the longer sliding bit (e.g. the head itself) has its center of mass overhanging the end of the short slide it is sliding only on one end of the dovetail top and the opposite end of the inside of the dovetail. move it back and forth a whole heap and you get that wear pattern. Anyway, the correct way to scrape these things in is to get everything flat and parallel, then relieve the middle 1/3 of the short half. That way you won't end up with the whole arrangement doing a sterling impression of grandma in a rocking chair while you're trying to get chatter free cutting...

Some years ago, I worked for a German company ... What I learned is: a group of 10 Italian engineers after long discussion make a common decision and then they delivery 10 versions of same project. Instead 10 Germany engineers after long discussion make a common decision and then they delivery only one common, sometime too complex design. The best project result is when the 2 engineer groups are able to work together with respect and trust ... ... ... About EtherCAT, it is a special field BUS based on ethernet Layer 0, able to synchronize different actuators, the MAC (medium access control) is different from IEEE-802. ;)
@fpaolo634 жыл бұрын
@Evi1M4chine Sorry NO so simple! It require a special HW. The Bus use a sort of ring (2 ethernet interfaces for each node - in-> out). Master send a packet contains data for all the nodes. The first node in the ring receive the packet, extract its own data, forward the packet to the second and wait for fire msg, and so on... When master receive back the packed if no errors it send the fire msg. (This in few words).

Great video. Thanks for sharing this ancient work of art with us. Regarding the motors, I am an engineer and have spent quite a few years of my life doing high speed mechatronics (mostly servo control stuff). The one thing you really have to watch out for in servo control is making sure the motor and encoder are tightly coupled to the load axis and that the load is as linear as possible. Lag es no jueno!! Lag can cause the control system to oscillate (especially when it is trying to hold position) as the lag introduces a non-linear load; and, if you have powerful motors that is really bad - the motor will win and the mechanical parts will lose. One way to address this is make the control less aggressive and soften the tuning or change the system to use a more complex control algorithm. If you want to talk more about this, let me know. Also, one other Tuber I watch is Jeremy Fielding. He definitely seems to know his way around motors.

Regarding the unexpected wear pattern you mentioned at 6:30, Stefan Gotteswinter has a very interesting video about that, but I am currently not able to find it (I may add it here once I do). Generally, the longer piece of a dovetail slide will wear to become concave as the middle part is in contact with the other piece more often and the short piece just wears convex to match that. Since you are looking at the shorter piece of the slide, a concave wear pattern is expected. Because of this, dovetail slides may be scraped to oppose this pattern slightly (short piece concave, long piece convex), so that the wear improves the fit before it gets worse.
@georgedennison33384 жыл бұрын
I watched this yesterday, and have memory issues, but my reaction when he was confused by the wear was that it made sense. If I recall correctly, he was talking about wear at each end being more than in the middle, right? For something moving both directions and extending beyond the fixed ways, I would expect that to be the normal wear pattern due to the increased leverage as the moving table extends beyond the fixed ways. It might be a very small increase in force due to the overhang, but with thousands of reps, and progressive wear allowing more 'hang', it would gradually get worse. I was going to watch it again, then forgot about it, when I got sidetracked on the keep or replace the vertical lead screw. I ended up commenting about that, and forgot about the way wear. From watching him work on the trials bike and a few other things, I get the impression Tony doesn't have a lot of experience troubleshooting or seeing worn/broken stuff. Not a knock on him, he's actually been lucky he has had to repair things for a living! I have for most of my 66 years.

This is OK since I have about 2 decades worth of canned beans down here, and am still trying to beat my high score of bouncy ball on a paddle (12 bounces!)
