How to Make Chamfered Edge in Concrete - The Constructor
Grip the handle of the tool and insert the lower edge into the seam between the edge of the concrete and the form. Use the inner face of the form as a guide and work the tool forward and backward, using long strokes. 3. Repeat the above step using the edging tool. This time, use light pressure on the tool and create a uniform, chamfered edge.

The defi nition of grinding Grinding is an abrasive, path-based manufacturing process for manual or automatic machining of surfaces or for cutting off parts of using minerals and bonded abra-sive grit. According to DIN 8580, it belongs to the cutting group and to the subgroup of machining with a geometrically undefi ned cutting edge. Why grinding?

NC-Form Grinding of Cutting Edges - Semantic Scholar
Multi-axis high precision form grinding processes offer great potential to generate defined cutting edge microgeometries. Due to its positive hardness and toughness characteristics, cemented carbide is often used as a material in cutting tools [7]. Most cemented carbides consist of a cobalt matrix and the hard material
Blade Grinds
The primary grind, that reduces the thickness of the blade to form the edge, may be concave, flat, or convex. There is usually a secondary bevel which is less acute and forms the edge itself. This format is easy to manufacture.

A thread grinding wheel usually operates close to its maximum stock-removing capacity, and the narrow edge which forms the root of the thread is the most vulnerable part. In grain selection, the general rule is to use the coarsest grained wheel that will hold its form while grinding a reasonable amount of work.
