On account of the interference between grinding wheel and workpiece and small concave surfaces, traditional grinding machine cannot realize the grinding process; hence, a specialized grinding machine …
1. Hollow Ground. Hollow grinds are great for getting razor sharp edges. When knife fans gush over a "slicey" knife, often the blade in question has a hollow …
A hollow ground knife blade is one that's been ground to create a distinct bevelled, concave edge along the knife's cutting edge. This effect is achieved by having the grind start below the middle of the knife, producing a small concave wedge that's very sharp and easy to maintain. Many mass-produced knives have hollow ground blades, as ...

Hinzoko: (see HOLLOW GRIND) Hollow Grind: The inside of a hollow ground scissors blade, from the cutting edge to the back of the blade, is concave or hollowed-out. This hollowed-out area produces a lined inside edge which gives a …
The recommended wheel speeds during dry grinding is in the range of 3000 to 4500 SFPM (15 to 23 m/s). The higher wheel speeds may cause burning of the tool edges. In wet grinding, wheel speeds in the range of 5000 to 6500 SFPM (25 to 33 m/s) provide excellent results. In general, the higher speeds improve both wheel life and metal …
Nov 21, 2021. #3. I think my view differs from most, but For now just leave it if it's very thin behind the edge and if the concave grind rides high towards the spine. That concave shape makes it possible for the grind to be super thin behind the edge and go higher than other grind types. Which ads to the performance.
The time it takes to grind and polish a concave mirror using a grinding/polishing machine can vary depending on the size and complexity of the mirror and the precision required. However, it is not uncommon for the process to take several days or even weeks to achieve a high-quality finish. This is because the grinding and …

A metal-bonded diamond wheel is used in this experiment, and is shown in Fig. 2 (a), and the main parameters of the wheel are shown in Table 1.There are three trapezoidal micro-grooves with a radius of 0.1 mm and an angle of 90° on the grinding wheel for roughing, and six V-shaped micro-grooves with a radius of 0.17 mm and an angle of 44° for finishing.
A convex edge is slightly rounded (hence the name convex) as it tapers off to the finest point of the cutting edge along the blade. The convex edge is considered superior compared to other edge grind types due to longer lasting durability and less drag when cutting. Most other edge grind types have a tapering straight line, or concave, instead ...
