Bench Grinder. Removing vibrations, balancing the abrasive disc, faceplate and more.

I machined pressed on flanges and adaptors for the wheels then made machined balancing washers and thought it was all great. Then the wheels wore after some time and became unbalanced. Too much of a hassle the wheels had a lot of life left. I put on a machined cbn and a diamond wheel. The machined washers I had made were still needed to prevent side to side wobble ( I held +-.04mm at the periphery of an 8” wheel) and radially fit the shafts with no perceptible play or skipping while cutting. All in all setup was 10x less than abrasive wheels and they cut faster. I can’t be making stuff to make stuff sometimes. Got to just get on with it.

фу, на собачьем...

Excellent, thank you .👍

Thank you very much for this video. I will have to try this out on my bench grinder, which has really bad vibration, like yours at the beginning! I was not aware of the reasons for the vibrations and how it can be fixed. I thought it was just a „not so good quality machine“ and I had to live with it. You have shown that this is not the case and how it can be improved a lot. 👍

Balance the grind stone and every time you dress it it can be out of balance due to uneven density.

Amazing work Dude, thanks for sharing.

Wyważanie przez przyklejenie ciężarka do tak szybko wirującej tarczy to proszenie się o wypadek!

My 1HP Rikon grinder came with a milled cast iron faceplate

the nut on the end of the shaft is also not perfectly square and applies uneven pressure. This can be corrected using spherical washers.

You guys know how to talk? Why use an ANNOYING robot voice?

When I finish sorting my socks ,brushing the dogs teeth and washing my goldfish, I will do this right away.

Throw that china junk in trash and buy Swiss equipment,

Не покупай станки на Алике, и выучи нормально матчасть.

Doskonale wykonana robota, której się nikomu innemu nie będzie chciało wykonać.

merci pour tout ces précieux conseils.

Buen video saludos desde México.

Хорошо если то что приклеено пролетит мимо.

is it better to bolt grinder to the table or leave free standing with rubber feet?

👍👍

عملك راقي👍👍👏👏👏👏

I refuse to watch this turkey... super lousy synthetic voiceover. Dude, learn to read and do it yourself...

И этот противовес отклеивается и летит в лоб

Ha majd a fordító (program) tud különbséget tenni a daráló és a köszörű között, lenne mit mesélni. Most csak annyit, hogy a felragasztott egyensúlyozó nem túl biztonságos és a korong kopásával lehet, hogy a pozíciója csak ront a helyzeten. Az 1mm körüli váll a tengelyen soha nem lesz biztos támasztó bázis a tengely és a belső szorító perem között. Ha a köszörűkorongon fennmaradt a gyári papírkorong, fölösleges másikat ráhelyezni.

what is hard tape

This was awesome thanks

Hi folks. Fitting grinding wheels in industry is treated as a highly killed operation reserved to specialist trained fitters. There's a good reason for that. Don't mess with cheap grinders, buy a quality product. Yes, it's more expensive. Much nicer to use and much safer. Incidentally, those paper washers are important, do not leave them out. Check the wheel for cracks before fitting, a light tap with a small hammer and it should ring like a bell, if not, break it and dispose of it. Do not stand in the line of fire. Buy a machine with heavy duty guards and tool rests. Do not grind on the side of the wheel. Have a good read up about 'Grinding wheel safety' before ever using one. Wear safety glasses. Misused these things can kill and blind. The surface speed of a hobby grinding wheel can approach 60 mph, around 100 kph.

Wow

What about the unbalanced rotor?

Damn, I love the Russians! Every technical detail and sheer artistry of wheel balancing covered. Like everything they do, it is first class. Art, Mathematics, Physics, Space Flights, Lacquer Paintings of Fedoskina and Palekh, the Hermitage treasures, the Kremlin treasures, Rostov Finift, their gymnasts, the Bolshoi Ballet, Chekov, Pushkin, Dostoyevsky, the music of Prokofiev, Tchaikovsky, Rachmaninoff ... such an incredible drive for excellence. Keep up the good work. Subscribed.

Thank you! Большое спасибо!

สั่งเลย

It is obviously too much of a problem for the disc manufacturer to balance the disc and for the grinder manufacture to provide a proper disc……only because stupid people by this crap

This computer voice is one of the worst I've heard in a while

Thanks.

Never had that problem with my bench grinders, all made in USA, not China.

Einhell 🙈🤷‍♀ You get what You Pay

Kaptan tape and epoxy? What the hell are you doing

Stanislav, good job you live in Russia as your practices would not be acceptable in the west.

Firstly, you failed to "ring" the wheel to check it for cracks and defects - a basic check.

You fail to guard the wheel - no side covers.

You do not have the grinder secured to a bench or other secure mounting - your grinder may not walk anymore, but when you put pressure in it when working it will move.

The balance wait you attached was onto the paper washer - it is only as strong as the paper it will fail!

You bodge all the packing with tape and epoxy.

You are an absolute cowboy and this video should be removed as it shows unsafe practices and is just dangerous.

I have 40 years of working in engineering and you are not an engineer I would employ.

GOOD JOB !!!!!!!!!!!!!!!!!!!!!!!!!! :)

Not listening to a computerized "voice" when this just as easily be narrated by a real human

Awesome video, thanks 👍🙌👌😊

Thank you for the detailed guide. I bought an expensive brand grinder especially to not have these issues, but that didn't help, unfortunately I have to do all the things shown in the video. but at least i know how to do it.
