Hello, friends all week has been tiring, this time the second episode of the milling machine, I hope you all enjoy and like my project, warm greetings from me / debbynovrinal
Milling machine ? I expected a small one but that ain't a small one ! I can't wait to see what you build Debby , You are a wonder! one of a kind ! .....keep after it ! do something each day on it and before long it will be done ! WELL DONE! it's going to be a fantastic Mill ! I have much faith in you ! ....Bob.....
Just a beautiful expression of ingenuity and talent actually you make your works above functional but they are works of art.. and they should be encouragement to all us they are to me at least , you are a master in your craft "keep on keeping on" Dave
salut bro semua pekerjaanmu paten bersih dan teliti banget semoga bermamfaat buat semua orang dan kususnya dirimu salam hangat dari payakumbuh sumbar...
Хоть убей не пойму, для чего окна вырезали ? лишние трудо-затраты и создание лишнего напряжения в металле. Это только для эстетики, дизайн ? А так очень даже интересная конструкция, хорошо когда есть такой металл.
I have one of those Total grinders... one day (of the few i had it) it stopped working. Yours seems to be tougher considering the amount of work you put it through. Nice work, subscribed.
Your skills great but there would be big noise and chatter, when milling head will be at the top position. Even square tube with 4mm wall will be more stiff against twist moments. Column always should be closed loop. Best regards! You can do it)
Man....you need a oxygen/Acetylene cutting torch !.... I made a guide for mine and it could cut 1/2" plate straight as an arrow but it took practice to do that ! .... after a year of running out of Acetylene, I bought the propane tips for my torch and used propane instead of Acetylene .... and I never had any problems of not being able to cut thick steel ( like 2"x2" bar) it was much cheaper to operate and using a 25 gal propane tank lasted about 3 times as long as the Acetylene ! running out of Oxygen then became the problem LOL....( because I used it more often!) ...... if a cutting torch isn't an option where you live perhaps a larger 6" grinder would speed up the cutting process ? ....lets face it Nothing is going to hold up long under the hard work you do.... but a 6" grinder of good quality should last longer. I would imagine you go through a bunch of 4.5" grinding disks in that Makita grinder ! i found that the Diablo grinding disks lasted 2 times longer than the ones I had been using and they cut faster too. ...... I am Amazed that you can afford all that nice thick metal to work with ....But you have to have it if it's going to be a good machine! you are wise in building with the thick metal !!!! and not trying to skimp by using thinner stuff.... very SMART ! I hope you put a way to tilt the milling head, a Knee in the mill, and many speeds ....and most importantly a large table ! and ofcourse the all important AUTO FEED ! ... you don't have to have that but your building it ....build the best ! even if you only have one direction of movement on the table it will be so much better than just manual ! I wish you luck.... and success ! keep after it ! ....Bob.
UN lavoro davvero curato, sicuramente molto robusto, non conoscendo i disegni che hai fatto, ho solo qualche dubbio sulla precisione e la linearità di quelle barre esagonali, voglio vedere come completerai il movimento dei 3 assi. e come garantirai il parallelismo Con simpatia Paolo
@@DebbyNovrinal Your work looks really nice! but I think you should consider spending a few hundred dollars on real 20mm linear rails. You have put so much work into this that it would be a shame to compromise the accuracy and rigidity by trying to make your own. Getting good linear rails trued up is hard enough without trying to make them yourself...
@@vikassm is true that it gives one access from both sides, but it has plenty of access from the back, and was a shit ton of work to measure, mark, drill, cut with angle grinder, file with the electric file + manual work. That took like 2-3 hours.. like why waste so much time, grinding wheel and effort for no good reason.. unless there is a good reason i don't know about. It looks cool but aspect is not such a good reason.
@@aion2177 Can't say it's his motivation, but there probably are actual benefits for doing so: In the simplest 1dof mass spring system, the natural frequency is given by w=√(k/m) where k is the spring stiffness and m is the mass. Therefore, reducing the overall mass of the system without significantly impacting the stiffness can be an effective way to increase the natural frequency of the structure. Say, for example, that you have a machine with a maximum spindle speed of 6000rpm (100rps), and are running primarily 2 flute cutters. Simplistically, you have a range of forcing frequencies between 0hz and 200hz. If the minimum natural frequency of the structure is say 20hz (completely made up for sake of example), then every frequency that the cutter might induce that is a whole number multiple of 20hz up to 200hz (10 additional frequencies) will cause resonance (ignoring damping, again for simplicity). If you increase the natural frequency to just 25hz, then there are only 8 frequencies to worry about. This is a very simplistic evaluation, but a lot of times people claim mass=damping (or that mass is always beneficial), but that isn't correct as far as I can tell. Basically, if we consider: F=M*a + C*v + K*u (where M=mass, a=acceleration, C=damping, v=velocity, K=stiffness, u=displacement) then we actually want to find an appropriate balance between M, C, and K to minimize the # of resonant frequencies and maximize stiffness thus minimizing chatter and maximizing ability to hold tolerances.
@@tyronesmith7307 very interesting explanation. I was able to follow :) Ive seen many examples of diy machines built where the rule of thumb was to just increase the mass as you pointed out. A bunch epoxy granite beds here on RU-vid. If your equation is correct then the goal is to increase stiffness not mass. And that is done by geometry usually. What domain of knowledge deals with this stuff? Mechanical engineering? and which branch. I wanna learn more about this stuff :)
is the price of steel in your country cheap? The price of steel in my country (Brazil) is so expensive, that to manufacture a machine like this, it's more expensive than buying it ready-made!
hola amigo.porfavor protegete del polvo metalico porque es muy peligroso .te sigo con mucho placer y interes desde Argelia .saludos y mucha suerte por todos tus proyectos. esperamos ver mas trabajos de torneria con tu torno rosca y todo ... saludos
here I do the work of making a lathe not based on planning or drawings, I do it according to my own wishes, I share it so that all friends can make it with the desired scale, I learn from seeing and understanding straight to work. I hope you understand, I am a newcomer youtube
@@erhamed6003 - I wish that were true in my country. In the USA, there are no foundries that do custom, short run castings at a low cost. It would be cheaper to buy a new machine.
@@erhamed6003 I know for sure you can buy a new vertical mill for under $2,000 US and a nice used Bridgeport for about the same so unless he is getting all his materials free he will spend a lot more building one.
