Weiler Abrasives has announced its new blending disc product lineup that is ideal for a wide range of blending, weld cleaning and polishing needs. The blending discs can help operations save time and money through faster material removal and longer product life in such applications as shipbuilding, structural fabrication and welding. 

The world of bevel gear grinding is a complex topic. How do you determine which grinding and dressing parameters to select for a desired surface finish? What type of grinding wheel should be used? What type of dresser should be used? How do all these factors affect the gear noise and quality levels? These are some questions that will be addressed in this article.

In many areas of application, it is uneconomical to use oversized universal cylindrical grinding machines for the external machining of smaller components - a lot of floor space is lost and the functionality is not fully utilized. With the new WPG 7 CNC external grinding machine, EMAG Weiss demonstrates another way of grinding workpieces with a maximum length of 250 millimeters. The very small machine requires only a minimal footprint, but at the same time features a whole range of high-tech components for flexibility and productivity. What is important in detail? 

From the outside, Gallmar Industries, nestled into an Oshkosh, WI, neighborhood, looks like any unassuming, medium-sized gear shop. Then take a plant tour with Gallmar’s VP of Operations Kenan Zolota—and prepare to be amazed. The facility stretches on like the Army’s warehouse at the end of Raiders of the Lost Ark, with everything from gear cutting to heat treat, gear grinding to inspection, all under one roof. Gallmar’s breadth of product line is in evidence too: defense-related transmission gears, 60-in. diameter internal gears for mining equipment, axle components for fire/ rescue trucks five feet in length, right down to a bin of brass ammunition casings that Zolota says are a special order.

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.
