Drum Surface Machining Made EASY!

[@georgesam7805]

Try this next time... See if you can get the bit as close to the tool post as possible. It will reduce the vibration and deflection and give a better surface finish. Also try and wrap the outside of the drum with large rubber bands if possible. It will reduce the harmonics and give a better finish. I've done a lot of truck drums. They're tough on a good machine

Thank for sharing this

perfeitamente 👏👏👏

Bravo KS Mechanical Engineering❤

[@KSMechanicalEngineering]

Yeah

[@neillawrence4198]

For some of the other comments I've read here. The mounting surface (face) was indicated true, the inner diameter was indicated true using an area that appeared to be beyond the wear area. I see no problem with the chucking and indicating. I am sure that before wasting time doing this job the drum was measured to make sure there was material to allow cleaning up without exceeding maximum size. The scary thing was the length of that grinding wheel arbor, but perhaps it was made for other jobs that need that much extension. Although not shown, I expect that after mounting the grinding attachment the wheel was dressed parallel with the machine axis. For anyone not familiar with grinding, dressing a wheel cleans and trues the wheel, making a straight and round cutting surface. It also exposes new abrasive particles that are clean and sharp to provide free cutting.

[@KSMechanicalEngineering]

Yes. Thank man for sharing this

Good job 👍

Хороший способ ,шлифовальный круг это сделает лучше чем резец👍

[@KSMechanicalEngineering]

It would be better than. Thank

[@jakebronger3568]

Well done, you have used all tools and the lathe in the correct way. Would be happy to give you a job AAA+

[@KSMechanicalEngineering]

Yeah man. This grinding tools is not use for precision parts machine

[@antoniocfsantos11]

Parabéns, o dispositivo de retífica feito por você, ficou muito bom, ficou muito bem dimensionado por isso não vibra. Vou copiar a ideia. Grande abraço !

[@KSMechanicalEngineering]

Thank. It work very well

[@siliconvalleyengineer5875]

how many thousandths was removed ? what grit is that stone wheel ? thank you for posting this video sir.

[@KSMechanicalEngineering]

I use 80 grit stone for this grinding process. Thank man

[@jeffwood8109]

I don't understand why you cut it first. Seems the post grinder could have been your first/only pass.

[@KSMechanicalEngineering]

We need to cut it first before grinding.

Jeffwood-I assume you've never machined anything?

[@jeffwood8109]

@Zzrdemon6633 oooo you're oh so superior. 🙄

[@garysgarage.2841]

The only reason he uses that grinder is because the break lathe does a shit surface finish.

[@I_Am_Your_Problem]

That will work.

[@KSMechanicalEngineering]

It will

[@josephcooksley3219]

Rooster Said no 😂😂😂😂😂

[@toma5153]

Right. The first order of business would be to measure the existing ID to see if it's near or beyond limit. Then a final Id check to ensure you're within limits. In days gone by I've taken drums to auto machine shops and their first item is to check ID before they even consider accepting the work.

You can get 2 sets of shoes to a drum but not a third.... without it coming apart

What “Tam” ?

[@trajonduclos7931]

This is why it is cheaper to buy new one, unless you are in India/Pakistan.

[@KSMechanicalEngineering]

Not that reason

[@trajonduclos7931]

@KSMechanicalEngineering I get it. But still a little humor? Chill out dude. I have been machining since 1986. This cut was elementary setup including indicators for true and square. But it STILL took WAY more time than I ,as a consumer, would be able to put in. Give me TWO NEW ONES at PREMIUM and it STILL doesn't cover my time. Sorry, I have first world problems.,.... But yeah that's how it is.

[@KSMechanicalEngineering]

@ yeah

Мы в России новые покупаем. Они у нас дешёвые.

16.5 inch drums are 120 dollar. All that work is a waste of time

Yes. It isn’t expensive for 120 dollar at your region. But at least we save 100 dollars from this repairing. Thank

Wrong way to indicate.

Maybe some point

@grumpyg9350 can you elaborate a little please im curious

[@martindennehy3030]

Waste of time, diameter will be wrong for shoes and thermal surface cracks are still there. Besides they're cheap.

[@KSMechanicalEngineering]

A little bit grinding surface. Diameter isn’t problem for shoes. And we don’t have any crack on this drum. Thank

[@sal8743]

Align the drum inside, where is worn? Really? Change job man.

[@KSMechanicalEngineering]

Less worn surface. And remove the rust

[@carlosalbertobarbosa7568]

Kkkkkkkkk.verdade
