This paper presents an effectiveness analysis of the grinding process with the use of a new multi-layer abrasive tool. The designed abrasive tool consists of external layers with a conventional structure, whose task is to decrease the grinding wheel load and ensure high grinding volumetric efficiency. The inner layer of the grinding wheel contains a 30% addition …

Grinding the wheat. My set up for the actual grinding process is as simple as switching from the whisk to the paddle attachment on a stand mixer. I love how KitchenAid keeps things so user friendly (I'm really not the mechanical type). The all-metal grain mill attaches to the mixer and the grain goes straight in the hopper. Place a bowl ...

For wafer thinning, the grinding process with a grinder is normally used from the viewpoints of cost and productivity. Since wafers are ground in the brittle mode, streaks called saw marks as shown in Fig. 1 are created and a damaged layer remains on the processed surface. In order to remove this damaged layer, a stress ...

I suggest you use a diamond tuckpointing wheel with a thickness close to the width of the mortar. You may need to pass the grinding wheel several times to remove the old mortar completely. Remember to wear a face shield and safety goggles, though, as the process can be really dusty. And the flying debris can cause serious injury.
