A balance washer can improve wheel imbalance. Make the washer about 3mm thick, and 70-80mm in diameter. Drill the shaft hole 1-2mm off center. Mark the wheel and washer. Try the washer rotated in various directions until the imbalance is gone.

Better make two washers (with centered shaft holes), clamp them together, (add index marks), drill multiple holes along 180 degrees of each washer's outer circumference. This way, rotating the washers relative to each other, it's possible to adjust the amount of weight correction from zero (index marks 180 degrees to each other) to the total weight of material drilled out from the lightening holes (index marks aligned).

Friends, if you don't have Somafix, use epoxy glue, it's even stronger. Epoxy gets into the pores of the abrasive disc and it's a stranglehold. They write to me here in the comments that it will fly off and gouge out the eye. They did not see and did not try to tear off Somafix, especially from a rough surface. Yes, I needed to show epoxy bonding, but I was sorry for the time, I'm sorry. I do not recommend any other glue except for CA Somafix and epoxy, it can really be dangerous.

Usually the motor shaft does not hit. Even this purebred Chinese has no problems with the shaft. Quality disc? No imbalance? This doesn't happen. Have you checked it for balance? It is possible without balancing, the easiest way: if you straightened it with a diamond pencil and the disk rotates perfectly, what do you say when it stops - vibrations appear? If so, then the disk is not balanced. By the way, the video uses German discs, pay attention to what is written in German. All discs require imbalance correction, even professional ones. To do this, they are supplied with special washers with three weights on a circular offset groove. Type in the search for YUT "removing the imbalance of the abrasive disc."

The plastic bushings for the grinder wheels are junk. Metal ones are available, and are far more accurate. I do dress the sides of the wheels to true them up as well.

They are not made for grinding carbon steels though, only hardened metals.

Thanks Grain for you ideas. Starting with a proper face washer and bushing. Only thing I do not like is the glued balance weight. We got to imagine that it COULD come off! How about drilling some weight out on the heavy side? Will this weaken the grinding wheel? Another thing, not to simply press the dresser against the wheel, but hold it firmly against the tool rest so it's only cutting on the high part of the circumference. Even better - I think - I got a cheap single-point diamond dresser and am making an adjustable holder for this to slide across the edge of the tool rest. See Mr Pete #798 and #799. Overall it is a lengthy job to get a vibration-free grinder starting even with a quality machine. Everyone, please be careful!

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.

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.

Зачем 2 раза править диск, сказал этот парень и обточил его 2 раза… А если серьезно, то я думаю, начинать надо не с замены штампованной шайбы (хотя это тоже важно и нужно), а с проверки люфта в китайских подшипниках и ровности самого вала мотора. Бессмысленно точить новую упорную шайбу, если вал кривой, а шарики в подшипниках квадратные. Но вообще все остальное по делу. Лайк заслужил. Одно маленькое замечание для тех, кто будет повторять: если уж вы будете заказывать у токаря новые прижимные шайбы, то имеет смысл заказать и вторую большую шайбу с канавкой для грузиков, чтобы можно было балансировать камни прямо на устройстве. Если пойти в своем безумии еще дальше, то самым идеальным вариантом было бы изготовление конусной насадки на вал двигателя, заказ новых камней с посадочным отверстием 50 или 76 мм и изготовление прижимных шайб с очень плотной посадкой на камень, которые бы оставались на камне до момента его смерти. Иначе получится, что при каждой переустановке камня его заново надо центрировать, балансировать и подгонять. Посмотрите на устройство больших заточных и шлифовальных станков - там это реализовано с завода.
@grain-diose2 жыл бұрын
Подшипники это само собой, это по умолчанию, поэтому я и показал сперва биения вала. Это обсуживание и ремонт, видео не про это. Кстати, у чистокровного китайца Worcraft подшипники не менял, а издевался я над ним много, в частности много токарил на нем, т.е. сильные боковые нагрузки. А вот в немецком Einhell вскоре пришлось, хотя использовался в штатном режиме и совсем мало. Насчет 2 раза править диск, видимо это проблемы перевода. Я имел ввиду лучше 2 раза выправить геометрию алмазом, чем 2 раза корректировать дисбаланс. И если быть до конца честным, то по мере стачивания диска небольшой дисбаланс снова появится - чисто по законам физики. Поэтому можно грузик чуть меньше ставить или по мере стачиваният чуть снять. А вариант цельной шайбы со втулкой (что в следующем видео) показал еще лучший результат даже на "китайце". Разумеется, если он и на вал плотно садится, и диск на него.

Very interesting and informative. I am surprised that there is no mention of CBN wheels.

Thanks, the goal was to talk about balancing the disk and the faceplate. By the way, there is already a video about two ways to make a faceplate.

I never felt so many regrets as after i bought this grinder, it's soooo weak i can prevent it from running with 2 fingers.

Interesting I checked my recently bough grinder it has a proper base plate but the disc is new and not balanced. I never knew to check that when purchasing just went to 1 200mm machine from reputable machine shop worked out great.

my coworker applies too much pressure when he grinds so he ends up pushing the wheel out of alignment all the time , so where we used to go through a wheel in 2 years we have gone through 3 in a year
