A series of dry grinding experiments were carried out using a self-designed grinding machine system, as shown in Fig. 1.TiC-Steel cermet block, with a dimension of 53 × 23 × 13 mm 3, was used as the experimental specimen, and the 23 × 13 mm 2 upper surface was considered as the grinding area. The surface of the specimen was treated in advance before the grinding experiment.

2. Grinding wheel safety: • Only use grinding wheels rated for a speed higher than 3450 RPM (maximum RPM of the tool). • Inspect wheels for cracks or fragments before start-ing the machine. Replace damaged wheels imme-diately. Never use a questionable grinding wheel, as the RPM of the machine can send broken wheel fragments flying at high ...

A stump grinder is a heavy-duty machine designed to cut the wood fibers of a tree stump and buttress roots using immense power from a spinning cutter wheel. The idea is to remove all visible traces of the woody tree parts that protrude from the ground after the tree is cut down. Stump grinders are large and expensive, and it would be unwise to assume that an untrained worker can safely operate ...

Metal-bonded grinding wheels are ideal for production / re-sharpening of very small cutting tools, or production of shapes with high accuracy (e.g. grinding of tap cutters, profile grinding of dental burs, etc.). Main benefit of metal bonds is very high shape shape stability. This comes at the cost of lower removal rates of material.
