Dresser

Grinding wheel dresser

As the abrasive grains wear down, the grinding capacity deteriorates and the friction against the workpiece increases. If a coating of chips forms on the grinding wheel, loose abrasive grains scratch the surface to be treated, or the shape of the grinding wheel begins to change, then the time has come for SIEVERT grinding wheel dressers. The sanding roll consists of: Quality steel wheels with U-shaped teeth pressed from a single piece. A special hardening program brings the teeth to a precise degree of hardness. This guarantees minimum wear during sharpening and dressing. Corrugated support discs between the toothed discs give the toothed roller stability and strength. The replaceable roller can be used until the teeth are completely worn down. The dresser has a nipple for pressure lubrication, essential for high rotation speeds and a long roller life. A sturdy handle made of precious wood enables a firm, comfortable and two-handed grip. Supporting lugs facilitate even contact between the roller and the grinding wheel. They also simplify lateral movements in order to dress the entire width of the grinding wheel. A protective plate prevents sparks from spraying against the face and hands.
