Advise please on Sanvik dual disk 2 teeth sharpening.

[Scott Walker]

Hello looking for any advise on sharpening the sandvik teeth on our Carlton stumpgrinder I've got the diamond disc to sharpen with and I know being sandvik teeth they dont need to be sharpened as often as other teeth, just wanting to know the right way to go about sharpening them.

 

Thanks for any help

I use a heavy duty 10" bench grinder with a standard aluminous oxide wheel and a green stone (silicone carbide) wheel. Use the standard wheel to grind back the steel part of the tooth by around 2 or 3mm. Hold the tooth sideways on with some mole grips and take the steel portion (above the carbide) back by whatever you need to, depending on how much you need to grind back the carbide.

 

Don't grind the carbide with the standard wheel and don't grind the steel with the green stone.

 

Using the green stone, grind back the leading edge of the carbide. Hold the tooth straight on towards the wheel and angle it slightly up to match the original shape. You don't need to grind the bottom face of the tooth (the face which hits the timber first), only the front edge and maybe a bit on the corners where it's rounded.

 

Does that make sense? I can take a couple of pics if you want me to.

 

The steel grinds back easy but the carbide is hardcore and takes some doing. Always wear a dustmask and goggles when grinding, especially with the green stones.

Yeah Johnny I agree. I only keep doing it because I bought this flippin' grinder and some wheels. The time it takes to sharpen them up, I could go out and earn enough money to buy some new teeth instead.
