А мне интересно отчего у тебя мурашки?! Где и для чего это можно применить? Просто бесполезная игрушка

I got goosebumps because of the way he works and the clean shop he has.. I would absolutely say it's not a useless toy, but an exremely useful thing, if you need some smaller precise cut pieces, especially if you have a "contained" space workshop. Anyway, depends on what are you using it for.@@user-mc6ew4jo2g

I'm a total f'ing mess compared to him/her

Yo quiero esos sistemas

hola, saludos, con la mejor onda, no lo copies, comprale el plano. la plantilla.

"Scrap metal" lol. The entire thing is made out of extruded aluminum. There is nothing in this project that is scrap. "watch it work with a big smile on my face" lol. You sir sound like you'd have trouble getting this to work even if you bought a kit with precut lengths and predrilled holes. lol

@@paulweston8184, he meant that he wants scrap to cut just to see it works, but you're malfunctioning.

And the second end-stop should move the grinder back to start position (two relais should do the trick).

@@marcoknives it is not wise to return the tool through the material, especially if the rotation decreases with contact to the cutting surface

With a controller and a servo or stepper motor and replacing the grinder with a router, it can become a single axis CNC to perform simple and accurate milling and cutting operations. By adding Z axis stage with router, it can mill slots and drill holes. While not as capable as a 3-axis CNC, it can be just enough CNC to perform most operations needed in a typical shop without all the complex programming and structural rigidity required for a 3-axis CNC.

To me also adding an OA E-Stop would be good in case something goes haywire.

I thought the same. Never been keen on metal cutting blades they can crash and at that speed I wouldn't want to crash ... Dewalt have a diamond metal slicing blade now, they last quite a while cutting soft metals and keep their dimensions (don't wear down).

I wonder often you need to replace the end clamping rail since its being cut each time?

Main problem is that diferent speed is needed for the diferent materials. Disk or material will burn if disk is too speedy.

Agree. A quick release nut mechanism should be used for operator convenience. Without one it would mean having to run the lead screw in reverse to move the drive nut back to a useful position every time you use it. A 'simple' way to do it would be to cut that nut in half and implement a 'half nut' mechanism like a lot of lathes do.

Sorry, but He is going to rub your face in the callousness of your comment over the next umpteen projects, whereby this is the tool that he uses to show us what we can make with our own two hands...and a little of his borrowed ingenuity.

You ever worked with cutting metal (accurately) before?

I think it’s a woman

Have you worked in a workshop yourself? You would know that women also work in workshops.

Я думаю, что для настоящего шлифовального круга у станка недостаточно жесткости. При малой жесткости системы высокие скорости приводят к вибрациям, уменьшающим точность, класс шероховатости обрабатываемой поверхности, увеличивающим износ круга. Круг может разбиться. Это опасно.

There is... the word is "JSK koubou"

Accuracy and neatness is costly and time consuming Hence things are produced in bulk and with tolerance Quantity has a quality in itself That's why Germans lost to Russians And Americans lost to vieatnemis

Да, уж! Всё у него аккуратно и красиво! А тут, если слепишь какую самоделку из хлама, вроде работает, но показывать её стрёмно.

@@user-ry1md7dq5k ,что бы как у него было нужно просто душу вложить,даже если из того что есть.

@@Tibrovich душа не поможет ты посчитай по бабкам сколько стоит его самоделка... там душу продать придётся с нашими доходами то

@@user-gm4hg7nw4l Внимательно прочти комментарий Олега ,потом мой 😜комент .

At least someone who can think... Nice work, nice hobby, but the machine is basically useless 😎 But yes, the guy knows his stuff...

@@Frank_inSA Why it useless? And why the is useless? If you want precise cuts, both the fixture part and the feeding part guarantees consistent results, not to mention the cases when you have to cut in series.

В чём цивилизованность? И в чём точность?

True that😂😂😂

I think rocket also can

😂😂😂

Probably better quality given how boeing been under fire for bad quality

I agree

You extend the blade diameter as well which cannot be done with hands

Another impressive angle grinder build. Bravo! One thing that might help make it safer and more efficient would be to use a belt to move the angle grinder instead of a threaded rod. With a threaded rod, the blade is being forced along at a set rate which could be too high for a given material or too low, which wastes time. With a belt, you could have an idler wheel on a sprung arm to maintain a certain amount of tension. If the motor is pulling the belt faster than the blade can move through the material, the tension on the belt will increase, making the spring on the idler wheel assembly compress. If you have a voltage controller attached to the idler wheel assembly that changes the voltage sent to the motor depending on how much the spring is compressed, then, when the feed rate is too high, the motor will automatically slow down, speeding up again as tension is released. ideally, it will fluctuate around a feed rate that matches the speed at which the blade can remove material. (If the speed doesn't change during a cut, you know that you can safely increase the motor speed. ...in theory, anyway.) Does that make sense?

Áqá

the courde you made the pully belt with where did you source it?

This is fantastic and can be mounted vertically like your other saw. I have a 12" chop saw and it is just too huge. This configuration can be used for many things. With a little bit of Arduino work you could set it up to cut an exact width. The grinder could be replaced with a drill and holes could be drilled from 3D geometry. This would save time and add precision. All that would be needed is a sacrifical plank locked into place. ... This project is a 100% in my view! Thanks!

Nice

Please how much will it cost me to make one for me?

Кастрация не плохая , я её упростил бы, ещё сделал так что балгарка под 45 градусов резала бы

Резиновая трубка предохранит станок от поломки лучше, чем ремень ГРМ GT2 в случае, когда пила не сможет резать металл на такой скорости.

@@user-np1gp7yj9f Fair comment - hadn't thought of it that way.

Обращаю внимание , тавотницы он прикрутил сразу и собрал так , что одну уже неудобно смазывать, а когда прикрутил держатель гайки, так вообще сделал недоступной, а достаточно было повернуть подшипник
