Welcome to a new era of blade sharpening.

Burr King has been making industrial belt grinders and surface finishing equipment since 1951. And proudly in the USA :usflag:

The blade sharpener is based on the best selling Model 760. More information about the 760 can be found at http://burrking.thomasnet.com/viewitems/belt-grinders/-velvet-touch-three-wheel-belt-grinders-model-760?&forward=1

A video of the attachment can be found at

Burr King has been making BELT grinders since 1951. The machine features only the best components from the Totally Enclosed Fan Cooled 1 1/2 horsepower motor to the rigid aluminum castings. This machine will outlast and outperform any machine on the market. Its not only a blade grinder, it's endless the things that can be accomplished with this machine.

The main drive wheel is the front contact wheel. Take off the attachment and you have a machine that would make the local fab shop jealous. If you remove the contact wheel you can mount any wheel (except a stone) to the 5/8 inch arbor.

But you don't need to remove the contact wheel to get the most out off this machine. With an abrasive belt (cost of approx $6) you can go from a 24 grit to 4000 grit. The belts wear just like any other abrasive. Life can be short if misused, but most of the customers are seeing approx. 75-100 blades per belt. This is a rough average. Some customers that sharpen frequently get 2 - 3 times the life. The nice thing about a belt grinder is that the angle doesn't change as the wheel get smaller, because the wheel never reduces in size. Since the wheel doesn't get smaller, the surface feet per minute (SFPM) never changes. Huge advantage.

"Do not stand in the direct line of the wheel for the first minute after turning on.
Do not use the side of the sharpener wheel at any time. "

These instructions came directly from a stone grinders instruction manual, it might have even came from a dedicated blade sharpener manual. If one guy says don't grind on the side, another guy says its okay to grind on the side of the grinding stone, I wonder what the stone manufacture says?

We use only abrasive belt technologies. The stones are just too dangerous. If a belt breaks, you might get hit by the belt, much like getting slapped with a leather belt, but you're not getting pieces of stone flying everywhere.

And did you read the wheel manufactures instruction that you must wait a minute prior to using the wheel. I guess the claim that you can sharpen a blade on a stone in less then a minute is only true if the machine is already running. That being said, the belt turn it on and go!

an 8 inch stone has approx 25" of abrasive length, our abrasive belt has 60". With the longer belt, you have more surface to dissipate heat. Also, we use a serrated contact wheel that allows air to pass between the belt and the wheel, this also allows the part to accumulate less heat. I know it sounds strange to most, but it's almost something that you have to see in person to believe. The down side to a belt is the amount of abrasive that is actually purchased. A stone wheel is all abrasive material, a belt is a thin layer of material on a backing. We have gotten anywhere from 40 blades to 200 blades per belt.

We sharpened at a show in Louisville a couple of weeks ago, 4 days, two 6 dollar belts, we sharpened every couple of minutes on average for the 9 hour day. I guess that you could look at it like the guy that mows the grass and doesn't pick up the sticks and other debris prior to cutting, his blades will not stay sharp as long as the guy that doesn't use his mower as a chipper. If you let the abrasive belt do the work, the belt will last longer, this is nearly the opposite as a stone. A stone is designed to shed its material to dissipate heat. That's why there's a stone designed for sharpening, its a stone that is "softer" and designed to shed quicker then a standard gray stone wheel.

The belts also have advanced cooling agents incorporated into them. So there's no need to run the part wet.

Which specific model is used in the video?

[BurrKing]

The blade sharpening attachment can only be used on the Model 760. It features a 1.5 HP motor, and a 1.5" x 60" belt.

Very, very nice...

I believe that belt grinders are the way to go to sharpen blades but I have not yet found the "perfect" set up.

At more than $2,000.00 your Model 760 misses the price point of most LCO's which I estimate to be under $900,00 for a very good set up, or $1,200 for the "perfect" set up.

Here is my suggestion:

Make a belt grinder with a bigger front bottom wheel (against which the blade will be sharpened). The bigger wheel will allow for better cooling and a flatter bevel. The wheel needs to have serrations, holes and fan blades shapped in its hub to evacuate heat.
The grinder must have a robust and easily adjustable blade holder with indication of bevel angle and adjustable stop for length of sharpening.
It must have an integrated grit collector with dust extractor connector.
The sealed motor could be 1 to 1.5 HP, direct or belt drive, and the SFPM should be above 7000.

Retail price point should stay under or close to $900.

Now, jump on your drawing board and make this "perfect" blade sharpener for us (before someone decides to get to his Autodesk Inventor and beat you to it). :usflag:

You can put me first on your buyer list, in front of the thousands of LCO's who will buy this blade sharpener... :waving:

[BurrKing]

I guess that for 900 bucks, a machine that has everything except quality we could go to china and have something made?!?

I think we need to make you happy, Happy. Let me know where you're at and we will make sure you get the opportunity to see this machine first hand. We have most of the items that you are recommending and a couple that you didn't mention.

The 760 is going to be in the repair shops. They are interested in making the money and time is money for these guys. I just talked to a shop that did 2500 blades last year. Now that's blades that are in the computer, who knows how many were done for cash!

2500 x 5 bucks a blade = 12,500 in just one season. $225 in abrasives, and time, most of the blades he believes were sharpened by his mechanics, ($50 shop rate) and he figured that it takes 10 minutes a blade on his stone grinders. His guys spent 400 hours sharpening blades!

The machine is going to take him down to 2 minutes a blade. Down to 80 hours. 320 hours saved at $15 bucks an hour. or 320 hours he can bill out at his shop rate of $50 per hour. In theory he could cash another $16,000 in shop rate receivables.

That is great for a shop and it sure saves a lot of time (and money).
For a LCO looking to get a fast sharpening system, it is above what most can afford.
I have no doubt it does a superb job though. :weightlifter:

I'm an lco and I bought one this year all I can say is wow! I love it it is so fast and doesn't heat up the blade. $2500 is alot of cash. but you can also buy a $7000 cub cadet or a $12000 kubota. you get what you pay for. do you mow lawns for $20 or $50? same thing.

I mow for $20 :drinkup:

What is the link to the blade sharpening attachment? I couldn't find it on your website.

[BurrKing]

If your looking for information on the machine, you can find it here on LS. or at a tradeshow. Currently we have made a choice to launch this machine differently then a machine that would be in an industrial manufacturing shop. We felt if we were able to speak with the customers and educate them on the machine we would have a better relationship with the endusers and have a better understanding of what the industry needs in a machine. And that has happened.

It has been great to watch this machine sell by "word of mouth" I think we hit a home run on this one. Not only do you have a great Burr King belt grinder, you also have the advantage of the blade sharpener attachment. Or maybe you may see it the other way around. Either way, by educating our customers and providing the best service possible we have made this product successful.

I have attached the flyer for anyone to review. If you would like to speak to someone about the machine call the Burr King factory at 800-621-2748. Ask for James or Paul
