As early as the 1920âs people began experimenting with rotary mowers, it took decades for the technology of small engines to catch up with the design. It wasnât until the 1950âs that the
first rotary push mowers started showing up cutting yards across America. From there mowers became bigger, added more blades and the blades were made out of more steel.
With the new technology came another hurdle, sharpening the mowerâs cutting blades. Many companies began to modify ordinary pedestal grinders to sharpen blades. Something else happened in the
1950âs, Burr King Manufacturing started using coated abrasive grinding belts instead of stones.
Even back in the 1950âs the inventor of the Burr King grinder realized there must be a better way to remove metal, the use of a stone just seemed barbaric. The Minnesota Mining and
Manufacturing Company (today known as 3M) had found ways to join the ends of pieces of sand paper to make an endless loop. Now a machine was needed to run these âendless loopâ abrasives at
high speeds.
Burr King Manufacturing was there with an answer. It wasnât until just the last 30 years that coated abrasive technologies became superior to bonded abrasive wheels. With the invention of
ceramic abrasives, such as 3Mâs Cubitron and Norton Abrasiveâs Blaze belts, bonded wheels have a limited future.
Ceramic abrasive grain is a chemically engineered ceramic aluminum oxide mineral that has a unique âstay sharpâ crystalline structure, which continually reveals fresh cutting edges on the
surface of the work piece ensuring a sustained cut and longer product life. This durable, cost-effective abrasive solution
delivers real productivity benefits across an operation without the premature dulling associated with traditional abrasives. The secret not only lies in the belt it also lies is the machine.
For over 70 years Burr King has manufactured belt grinders
that utilize coated abrasives to their fullest.
Preformance:
The invention of the internet and the advent of Youtube has allowed videos to be posted on line. But take a closer look at those videos of others sharpening lawn mower blades. The truth
is a stone grinder canât remove the same amount of material that a Burr King can.
Deceptive at best, these others claim to sharpen a blade in less than a minute, but look close and youâll see the truth, they are not sharpening a dull blade
The Facts
Only Burr King blade sharpeners use coated abrasive belts. Get out of the Stone Age, stop wasting your time and money with old technology. Join professionals worldwide that
have chosen Burr King for their grinding needs.
