Shop Made Diamond Tool Sharpener

[Mike Walton]

i made a diamond tool sharpener for sharpening carbide metal scraper blades and biax carbide blades.






it turns at approximately 280 rpm.
the wheel is 75% concentration diamond 600 grit, 3" diameter.
i use a few shots of windex to cool the carbide during sharpening operations.
the platen is flat and level, the motor is tilted 3* and is adjustable.

thanks for reading

Mike, where did you source/salvage the motor?

[DIYer]

Interesting, using Windex as a cooling agent.

Hi Toller,
the motor was salvaged from a food industry label applicator.
it is approximately 6:1 final gear reduction, 1740 rpm(before output reduction), 115v motor.

just about any fractional horsepower motor could be used with a little forethought.
the slower the better, but 250-17XX rpm would be a good range.
a motor in the 17XX rpm range could be employed with success, but heat will be a factor and additional cooling may be a prerequisite for long sharpening cycles.

Windex is very cheap and very effective for a cutting agent.
i use windex or the cheap dollar store window cleaner interchangeably.

thanks to all who have read and watched!

Mike,

Why are you running it so slow? Is it because you are using it manually or was it a case of that is what the motor does?
All the CBN and diamond wheels like that in my experience are rated at several thousand rpm, depending on diameter. I run my T&C grinder at 3 to 4000 rpm

The grinding wheel is intentionally slow for honing.
It is not intended for grinding like a tool and cutter grinder.
The intended purpose of the sharpener is for Biax scraper blades that have already been sharpened before.
The honing is more controlled with slower wheel speeds.
