Schneidsegmente

Schneidsegmente are modular cutting segments that form the cutting edge of certain circular blades and grinding tools. They are typically made of carbide or diamond-impregnated materials and are brazed or soldered to a steel core. On segmented circular saw blades, especially those used for masonry and stone, the blade consists of a central core interspersed with a sequence of Schneidsegmente; gaps between the segments facilitate chip removal and cooling, helping to prevent overheating.

Construction and geometry aspects of Schneidsegmente influence cutting performance. Segment shape, height, width and the inclusion of cooling grooves affect heat dissipation, chip flow, balance and vibration. The segments are designed to withstand the stresses of high-speed cutting and abrasion while maintaining a sharp cutting edge.

Manufacturing and mounting procedures vary by material. Diamond segments are often produced by sintering and then brazed onto the core, while carbide segments may be brazed or mechanically fixed. Proper mounting, control of run-out and correct tightening torque are essential to avoid blade imbalance or segment detachment during operation. Some designs allow relocation or replacement of worn segments to extend blade life.

Applications for Schneidsegmente are common in construction and quarrying, where segmented blades are used to cut hard materials such as concrete, reinforced concrete, stone and brick. In metalworking, carbide segments may be employed for high-speed cutting of harder metals, though this is less typical than in masonry applications.

Safety and standards: use appropriate personal protective equipment, follow manufacturer guidelines for cooling and feed rates, and inspect blades for cracks or missing segments before use.

Etymology: the term derives from Schneiden (to cut) and Segment.
