Hollow Grinding Tormek

04-10-2021· Using a water cooled Tormek, it is easy to forget how often we burned tool edges with a dry grinder. Good practice was to stop short of fully grinding the edge and finish off with bench stones. The hollow from the dry grinder reduced the amount of hand grinding needed. This is not needed with a Tormek. The electric motor provides all the power.

02-10-2020· hollow grinding revisited Tormek. 2017-7-5 A third view is to establish the primary bevel with the Tormek SG grinding wheel and then add a micro bevel using the Tormek SJ polishing wheel. In my opinion, establishing the two reference points with a hollow grind to allow alignment of the blade on a flat stone does not reflect Tormek thinking.

The mathematical part of my brain tells me there is a difference. If I examine them very closely I think I can see a difference, the T4 grind having more hollow grind.

30-10-2018· The shallow hollow produced by the Tormek does not bother me. At least not when there are small flats added to it by honing the edge and shoulder of the bevel. I first came across the concept of a "flat over hollow" grind for slöjd knives in

The hollow grinds end up being both completed faster and more consistent, not to forget the hollowing process is so well controlled, that it become viable to grind close to the edge of the blade.
