Continental Diamond Tool Corporation (CDT) proudly announces its partnership with Krebs & Riedel, a global leader in the abrasives industry. This collaboration positions CDT as the exclusive North American source for Krebs & Riedel abrasive products within the USA, Canada, and Mexico.
Weiler Abrasives recently announced the next evolution of abrasives — Tiger 2.0 zirconia alumina and aluminum oxide cutting, grinding and combo wheels. Designed for demanding metal fabrication industries like shipbuilding, pressure vessel and heavy equipment fabrication, these abrasives help cut through inefficiencies, safety issues and labor shortages that prevent companies from doing their best work.
Continuous generating cylindrical gear grinding is one of the most demanding grinding applications for automotive and aerospace manufacturers. To improve gear efficiency, gear life, and noise levels, gear profile tolerances and surface finish requirements are becoming more stringent. This is especially true for EV gears, which typically require lower noise characteristics than traditional automotive gears. These new quality requirements must be maintained without sacrificing cycle time, and without inducing grinding burn.
A significant amount of work is being done to advance the technology of gears specifically for use in electric vehicles. No longer hidden by the noise of the internal combustion engine, the transmission has taken center stage as the noisiest component in most electric-driven cars.
Recognizing the role robotics plays in adding efficiency and lowering production costs for manufacturers of all types and sizes, Suhner continues to expand its robotics offering. The fully electric EFC-02 delivers precise, constant force throughout robotic grinding, sanding and deburring processes—resulting in superior, consistent surface quality.
Serial production of large gears requires a high level of quality, excellence, and continuity in production. Emphasis is placed on maximum synergy between the grinding machine, the grinding process, and the grinding wheel. After several successful trials on various Klingelnberg Höfler Rapid grinding machines carried out by Krebs & Riedel with customers in their production facilities, Krebs & Riedel has received several large orders for grinding large gears from abroad and has introduced the new premium grinding wheels with high process reliability.
JTEKT recently demonstrated a new double-disc horizontal grinder that simultaneously grinds both sides of silicon wafers to +/- 1 micron from as-sliced condition. The DXSG320 performance represents a massive improvement in accuracy and productivity over the single-spindle vertical grinders common in the chip industry today which grind to 3-4 microns, according to the company.
In acquiring the Turkish Egeli Egesan Group the Tyrolit Group continues to implement its business expansion strategy and has further strengthened its position on the international abrasives market.
At IMTS 2022, Norton ׀ Saint-Gobain Abrasives (Booth #237042, North Hall) will offer a portfolio of gear grinding products specifically designed by category to provide higher profile accuracy, supreme form holding and burn-free grinding in worm, profile, and bevel applications. Highlighting the range is an innovative dual-worm wheel design that enables two operations in one grinding wheel, substantially saving time and cost.
