More valuable lesson. Best thing to happen to UA-cam !
Thanks for the kind words Brian.

Hi Steve. Looks to be a nice wheel for what we know little of. We are happy you are teaching us the concentration and the quality even function of this wheel and how it is dressed, as well you did great teaching us about the special wheel dress made for dressing a CBN wheel. Nice lesson for our future uses, thank you. We think we know that part you are grinding, that is the base for the shop made squaring tool.
Nice adjustment upgrade to that Suburban Tool for your application very well shared Steve.
Lance & Patrick.
Hi Lance & patrick,
We are happy you are finding value in the videos. Thanks for watching.

This video really will come in handy when my new CBN wheels arrive to surface grind Rex121 steel knife blades at 71HRC or S390 HSS steel blades at 68HRC. Thanks so much for this!! I really appreciate the time you took to record this. All the best from Switzerland 🇨🇭!
That stuff is not fun to grind with anything but the CBN will be the best choice.

@@SolidRockMachineShopInc I tried the CBN yesterday for the first time, it really made my life easier. Thanks again for the video, it enabled me to start right away! (And using those white sticks is really satisfying haha.)
@@kknives_switzerland Glad it work out for you. I bet that edge stays sharp a long time.
@@SolidRockMachineShopInc Oh yes, some members of the knife community (channel name Outpost76) did a cut test video a few days ago with 68HRC Vancron Superclean steel and a one inch section did cut 800 feet of cardboard before it stopped cutting copy paper. Quire a chore to make such a knife though - so I am happy when I think about my new cbn wheels, haha.
@@kknives_switzerland Check out cryogenic (deep freeze treatment). On many types of steel it adds 2-5 times the wear resistance and makes it tougher too. You can have it done as part of the heat treat process. One other type of steel to look at is CPM 15V, I believe it is the closest to carbide wear resistance you can get in steel.

Steve, I have watched you UA-cam videos for a few years now...and Every One is Packed
with Very useful information...I Always look forward to the next one...Because of you and
others like Robert Rendeti (sp?) Stephon, and you...my skills in my wonderful shop have
Exceeded anything I could have imagined just years ago...you have shared your valuable
knowledge with use and we are Very Appreciative...Keep it Up Please
That is awesome, we are happy the videos are a help to some. Thanks for sharing
Steve
A really info packed video. I have watched this one twice. You are gonna cost me money for sure...Thanks Steve.
Hi Robert,
You will love the CBN wheel if it is prepared and used correctly. It will be money well spent.
Steve
Great stuff Steve and gang. Love the adjusters.
Thanks Randy.
Steve
it is surprising how much their is to know about grinding wheels.
Hi Harold,
Yes, there are so many wheels of different types that it can be overwhelming especially to someone new to grinding.
Steve
"There"
Great video, very informative! Love your work!
Thanks Bill.
Steve
Thanks for explaining the preparation and use of cbn Steve.
You're welcome B Clare.
Steve
👍Thanks!
My diamond wheel stays on it's own adapter so as not to loose the trueing. Also made a reference mark to indicate any slip.
Indicated the wheel in before trueing so as not to remove too much diamond per Norton's recommendation.
Hi James,
This wheel was tight on the adapter, I doubt that I would have been able to move it more than .0005. It ran out less than .002 when first mounted.
Steve
That video gave me some answers to some questions I had about CBN wheels and the way to get them dressed.... Thanks!!!! 👍👍
Differential screws, quite smooth way to advance slowly in a controlled manner... 🙂🙂😎
You're welcome Pierre.
Steve
Great information. Was thinking of getting a CBN wheel....later on....much later on now.
Thanks for doing this video. A lot of great information 😀
Thanks Dale.
Steve
This is so much over my head but I’m mesmerized watching it. Your explanation clear and easy to understand. Even for me 😳. Thank You BTW, still haven’t reground the cast iron for a surface plate per your recommendation but it’s coming. Need a semi accurate work stop for the backside of the mag chuck. Excellent video 👍👍👍
Thanks Ron,
Let me know how it comes out when you get to it.
Steve
Thanks very informative - all looks useful in perfecting your comparator build.
You're welcome Rick.
Steve
Nice work Steve! Enjoyed.
ATB, Robin
Thanks Robin.

Wow Steve the Master Grind is awesome. In the hands of someone as creative as you are some very intresting grinding is on the horizon. I find information on cbn wheels intresting the topic of truing and dressing some people get up set about the terminology and what covers what (did you dress that to an angle or true it to angle) scince it required subsequent dressing to open the grain. like a die grinder freewheeling not plugged into air for dressing if its loading up. Your great, love the awesome custom cool stuff you make. Thanks Steve
Thanks you can use it,
I already love the Suburban Master Grind. You will see more of it in future videos.
Steve
Interesting video Steve.
Thanks sound limit.
Steve
GREAT VIDEO !!!
Thanks Old Wipper-Snapper.
Steve
to get the benefit of a CBN wheel you run it twice the speed (8000sfpm), ample coolant and a rigid set up.
I only have one speed on my grinder.
Steve
what speed are you using
Very helpful info on the CBN wheel, we don't have a surface grinder but do have a cuttermaster grinder with a CBN wheel on it. I'll know next time to soak the dressing sticks first. Your wedge adjuster is really cool! So the 10-32 is fixed in its block in your differential screw design?
Hi Bil
The 10-32 is fixed to the 1/4-28 with a coupler in the middle. The block on the end is tapped for 10-32.

Hi Steve, Great vid on how to true and dress a cbn wheel. I wish you could've added a small segment on how you side dressed (not true, you showed that) the cbn wheel. I used your information (on a previous vid) on how to true and dress a diamond wheel to great success. I was able to make my own precision ground flat stones from that vid. Also, what is that meter that I see you and Robin use for measuring small lengths i.e. .00005" or less? What is it called, do they still make them, who sells them?
Hi Robert,
That is a Federal Amp Gage. They do still sell them. This is an older model that works great. I bought it off Ebay for a very good price. Robins is a Brown and Sharpe and he like those better. Mine has a 5 millionth resolution his has a 1. We both like the analog over the digital ones.
Steve
I was not familiar with those diamond dressing sticks. Looks like they are just the ticket for trueing up those CBN wheels.
Hi Brian,
They work great and are fast, I love them.
Steve
Hello could you tell me what grit dresser you are using!!
Please tell me about the dressing on cylindrical grander O.D wheel and also guide me that which kind of dresser is use to grand my universal granding
What types of wheels are you using, Aluminum oxcide, CBN, diamond?
Steve
i have a diamond wheel like this that is very out of balance. my sopko rings can't make it balance. would you drill the aluminum on the heavy side to relieve weight? i can't figure another way
Yes, I would only spot face rather than go all the way through.
Steve
Where is the Dressing tool from? do you have a part number I can search for? Thanks!

what is the grit value of the grinding stone
The CBN wheel is 150 grit.
@@SolidRockMachineShopInc
is it possible to work on materials skh 51 HRC 63
@@ciswiyadiyadi6791 Yes, I have used CBN to grind materials over 65 RC. CPM10V and 15V. I use CBN to rough grind steels over 60 RC and leave .001" to finish with stone wheels. They do not work on Carbide, for that you need Diamond. You can uses Green silicon carbide wheels for carbide also but I never like using them for that.
@@SolidRockMachineShopInc where can I buy the CDT brand cbn stone
@@ciswiyadiyadi6791 I get CDT CBN products here www.cdtusa.net/
what is a CBN wheel
Hi Dan,
CBN is Cubic Boron Nitride, I believe it is the second hardest material known to man just under diamond. Unlike diamond you can use CBN to cut harden steel but not carbide. Diamond wheels for carbide, CBN wheels for harden steels.
Steve
thank you Steve
I have a diamond dresser
Some day I will have to get one myself.
Steve
@@SolidRockMachineShopInc ok I need to be contacted
those nibs glaze the hell outta the wheel. gotta stick the snot outta them to open back up. brake dresser works better unless you need dead flat
Hi Bruce,
It cuts the CBN and resin to the same level so you are correct you need to follow up with a stick to expose the CBN.
Steve
The abrasive in the stick is aluminium oxide or carbide, not diamond. You dress a diamond wheel with a softer material than the CBN wheel itself...strange but true...
Paddy
The white sticks are aluminum oxide A hardness. It id for cutting the resin bonding material not the CBN or diamond.
Steve
i think i am going to throw up
I hope you feel better soon.
@@SolidRockMachineShopInc felt better as soon as i stopped watching this. without a doubt this is the most brutal video on using a cbn wheel I have ever seen.
@@menotyou7762 That is to bad you feel that way. It is one of the methods used in industry and works very well. I get some of the best results using this method as do many others in the field. I have decade of experience using CBN and this method has never failed me.
@@SolidRockMachineShopInc for starters I get a CLEAN glass of coolant and keep my sticks in there so they are always ready and there is no garbage coming from my sump. I can tell that you have been taught by people that didn't care or know much. you should retitle your vid and say "how I true and dress" because honestly in most cases what you do is not correct. This in my opinion is the worst practice in a machine shop and I see it over and over again, operators thinking they are doing the right thing just because the finish product is ok.
@@menotyou7762 Everyone is entitled to their opinions. Like I said it is a proven method with amazing results. You can argue your point all you want but I will go with proven results repeated time and time again.
