Very nicely explained, many thanks from a novice at bench grinding. I bought a cheap bench grinder from Harbor Freight - Central Machinery 8" wheels. It rocks so violently it was frightening. I had no clue what to do. This is an art not a science to balance wheels. Slowly learning how to make this work. Its not how pricey the machine is, but how well balanced. If I succeed in truing my wheels I will consider it a major achievement in woodworking. Thank you very much for your time and expertise. I learned a lot.

good video a couple of chime in tips. its faster and more accurate to simply use a big ball bearing which I have them all sizes up to 2 inch and they are dirt cheap getting a box of ten even. then a person can use any surface ground block to set it on or even on the surface plate and adjust till it does not roll. works great for everything even leveling big machines. another method for balancing is to masking tape on various items such as small washers that have been clipped in half---------and jb weld them onto the wheel next to the blotter NOTHING can make them come off not even hammer and chisel. they will not fly off. also carbide grit which is dirt cheap and heavier than steel can be used in the jb weld-works perfect if a person worries the washers may fly off which they wont. That area way up on the wheel will never come close to being used. that method also works excellent for the problem there is no way to balance pedestal grinder wheels. on the arbor I do in fact make and sell them and the way I do them is take any nice round shaft and drill and ream a hole and make a bushing and also jb weld that on. then next day stick the shank in lathe and rough it out to the taper. take to grinder if a person wants perfection and using one of the cheap spin fixtures spin on the taper using what tilt device a person has. relieve the middle of the arbor a bit so it locks in easy on the two contacts. on the leveling using the ball a person with a balancing stand with the two legs simply set any ground plate on the rails and level the same way using the three point screw legs. on the jb weld thing at various places (I am 67 retired molds prototypes )we had all top dollar stuff plus adjustable balancers which of course I simply used that. but the jb weld is really the way to go otherwise and is so fast you wont believe it. once the wheel is balanced a person can use it months or years and it wont go out of balance especially since a wheel really does not have to be balanced perfect to an atom. when people get the washboard cup marks--actually that is not out of balance it is because nobody tightens a wheel enough--when roughing the impact on the edges then bumps the wheel over slightly. thats all was in writing mood.

Thx for passing on your experience, it is golden information. Carbide grit to weight the JB Weld is a good tip! I had been thinking that lead shot or filings would be heavier than steel, and lead does have the advantage of being carvable if it needed trimming. My application is the balance and tuning of bench and pedestal grinders, only.

Have you ever tried a small amount of plumbers epoxy to balance the wheel?

You are time limited with that stuff but if you go a little heavy you could dremel it off for a perfect balance.

One little tidbit of info for everyone. I've noticed Norton wheels quality getting worse over the years and here is something to watch for. They are sending out wheels that are WAY out of balance and they have to know it. We have sent back wheels that are so far out of balance that the machine vibrates even after dressing. Their dirty little secret is they don't junk them out, they try to inject balance them. If you get a new wheel that looks like someone has let a pop can sweat out on it, you've got a second or customer returned wheel. They must inject a heavy liquid into the wheel to weight the one side. You can see it easy on the 46 - 100 grit white wheels, others it's not as easy to see. The problem is, being that big of a round, it doesn't come off equal as you dress into that area so it will throw your balance off again. It would have to be a V type inject as your surface area gets less as you dress. The balancing stuff goes almost to the outer edge of the wheel so it effects it quick. Your paying full price for a good wheel so personally I don't want to deal with. Just a heads up to all of you in the industry to keep an eye on.

When you grind for a living you will have your own personal wheels on your own personal hubs. Another trick is to use shim stock between the hub and mounting hole of the wheel ( hub O.D./ wheel I.D.). Then you can tighten the wheel and true it up. This enables you to start the wheel and continue grinding without redressing.

I know this is an old video but you have responded in the past so I am hoping you will again. You have the experience and have constructive feedback. I had an idea on balancing surface grinder wheels without drilling the stone but the hub nut. The idea is this, a three legged stool can be aligned into balance from adjusting two of the three legs. I have seen and used this on my surface stone base. Once softened, three 60 degree set face drilled and tapped holes on the hub locking nut. Left alone should not effect function or static balance of wheel but can be filled with fractured lead shot compressed and secured with set screws. Yes a lot of work with trial and error but reversible, non destructive to hub and wheel but cheap.

That idea sounds really good and is probably effective.However I would not want to: soften and compromise the hub nut; and/or have 3 set screws spinning around at high speed just chomping at the bit to take off into low earth orbit.

I use 7" wheels and have never taken the arbor off my J&s 540 grinder. The wheels are such a small mass that they are never balanced. Usually the 3 weights on the nut are equispaced and remain so. My wheels are not stored on the arbor they are just removed from the machine by quickly removing the nut. I was taught to test for ringing by hanging the wheel on one finger and tapping with a piece of wood, usually a file handle, never strike them with a piece of metal.

there wont be any difference but you will have discrepancies associated with heat when grinding dry. I run a candle over the wheel after dressing. a big difference on burn marks on the surface is using a new large wheel--the interface of heat is MUCH bigger and with a new large wheel the feed must be faster.

@ShadonHKW6 жыл бұрын
Hi Al, Wheel manufacturers have created a vast wasteland of blends and variants to choose from. If you look at the white wheels (Alum Ox) as the meat and potatoes standard and work out from there, it will be much clearer. Grit: 46 for heavy stock removal, 60 for a finer finish. Hardness: stay in the range of H-I-J-K-L (with H being the softest) choose hard wheels for soft steels, and soft wheels for hard steels. Bonding: Use a vitrified bond (wheel class V) there is not much need to stray away from this. If you work out from this standard, you can start playing with variants, start with abrasive blends (Alu Ox- Ruby) pink or (Alu Ox- Carborundum) brown wheels. Hope that helps, Z

There is no need to tap the wheel in different areas around the circumference. There is no need to rotate the wheel 180°. Do not mount the wheel on an Arbor of any kind. Support the wheel from a piece of wire or string and tap the wheel it either rings or it doesn't. You only have to tap it once, not multiple times around the wheel. When adjusting a surface plate, level the end first THEN level along the length.

@chiragjoshi47744 жыл бұрын
Drilling on face of wheel is not advisable. Because it may generate hair-line crack inside the wheel and wheel can be broken during running. Instead of that you can pour some suitable balancing liquid materials on opposite side of heavy point to balance the wheel.

So you don’t have to wait so long for the oscillations to subside, you can put some way oil on the tops of your pillar blocks (123 blocks) to dampen the motion. An advantage of balancing the wheel itself on a non-balancing arbor, is that once you’ve balanced a wheel the fits the arbor without much clearance, you can remove and replace that wheel or put it on another arbor without much worry that it will become unbalanced.

Instead of breaking the bad wheel into pieces you could still get use of it as a whetstone. Lots of life left in them before the garbage bin.

Good video my man but I want to chime in on a couple things. Wringing the wheel is psuedo science and has nothing to do with working in a shop. It is taught in class when kids because some old timer came up with the theory--those old timers are now dead and would not hold a job today. On the balancing of the wheel I did an experiment at keytronics where I ground yes--to millionths for years. A wheel was vibrating hard and I wanted to document it would mess up the finish. I dressed the wheel and the finish was great. When a wheel is not tightened enough during roughing you get the cusp marks because the wheel is knocked off during the hard hits while roughing.. ( you showed tightening it down good_ however most people are brainwashed that the cusp marks are from out of balance wheel--they are not. For that reason ultra balancing a wheel to this day is way overplayed. Also you dressed the face but not the sides. The sides are always dressed for multiple reasons. That alone usually balances the wheel within reason. Not dressing the sides of the wheel also carries weight as to the other info. Something for people to know when getting carried away with balancing is that if you use this method (which I will use for my home pedestal grinder--I have no choice)--rest assured you will not be working long--as you practice these methods you are being replaced by japanese and chines who know not to use them. you will not survive in the work world. You will stay working only if you are in a shop ------------------------------working for relatives. Another situation in which a person could survive taking a half hour to balance a wheel is a shop that is making so much profit they dont give a shit and its amortized in. The balancing of the wheel should take no more than 90 seconds total. That being said I appreciate all the self help videos as they gain nothing for the individual except trying to help however I could not remain silent on this one.

That's really interesting. I work in a small CNC shop. Of course it's all about speed and efficiency, many products don't carry huge margins. So yeah, in a production environment taking half an hour to set up any tool will not fly. Also I have a "private" shop on the side where I have, among others, a Kugel Müller vertical spindle grinder which I was just starting up now after some repairs. I have read about the pros and cons of balancing. One statement was that a Norton Grinding book said that smaller than 8" wheels need no balancing. I can imagine big wheels do. I suppose the vast majority of the eccentric mass comes from the grinding wheel being off-center/ not dressed properly. Your remark about dressing the sides is relevant here. Dressing the wheel "all around" will be impossible on my grinder cup wheels - only the front face of the wheel can be dressed (with the diamond sitting on the magnetic table). The swivel action of the machine column can not be locked as far as I've seen. This is a special condition as compared to horizontal spindle machines. The Kugel Müller carries a plate on the front of the grinding head cover that says: "Haben Sie Ihre Schleifscheibe ausgewuchtet?" (did you balance your grinding wheel?). It also comes with hubs with 3 weights. Long story short, I will concentrate first on dressing and look at the results - research it further. Thanks again for the info.

You don't want me on your surface plate (espically while you are leveling it), and I don't want to be on your surface plate ... at least not without my cleanroom booties. Great safety information. Ringing ANY wheel, new, used, from a buddy or a stack at the back of the shop is no joke. What you didn't say, but since I don't risk demonetization I will say, is if the abrasive does not have a crisp ring (relative to it's hardness) mounting it could kill you, or at least send you the ER to have 1000 pieces of abrasive dug out of your face. Not a pretty picture, but a fact. Great video. I'll be looking for anything you might have on aluminum hub diamond wheels which I use for carbide sharpening. One of my favorite grinders in my shop is a very strange ultra high quality diamond grinder designed for grinding eyeglass lenses to fit the frame you pick. It has a multi axis mechanical cam drive system which can rotate a lens, move it into and away from the wheel, and a moving motor which actually moves the entire motor and wheel left and right within the housing. The wheel is a 6 X 1.25 inch multi grit diamond with a v notch on the fine side. I use it for freehand grinding carbide and with a jig I made for surfacing brazed lathe tool bits using the motor cam assembly. My point is "think outside the box" when it comes to home tools. I could never afford a grinder of this quality. I found this one at a auction for $32. Awesome!

What does saying that a wheel can kill you have to do with demonetization? That wouldn't get him demonetized.

I have a mill and a metal lathe and a small foundry and I know how too do my own castings can I make a surface grinder ??? .
@ShadonHKW6 жыл бұрын
Sure, but why? They are relatively cheap.
@danvandertorre92806 жыл бұрын
I don't have that kind of money 300$ bucks is the most I can spend a month and most the ones I have seen are 3000$ for old ones .I live in Canada Kelowna b.c.

Check out Dave gingery's books. He doesn't cover building a surface grinder, but he does build a lathe, shaper, milling machines, and drill press
