The latest technology on display in Columbus, OH. October 24-26.

Grinding fluids from Norton|Saint-Gobain, digital micrometer from Mahr, grinding centers from Haas Multigrind, updated software from KISSsoft.

EMO is arguably the most important trade show when it comes to the introduction of machine tool technology, and this year's show - taking place from September 18-23 in Hannover, Germany - promises not to disappoint. We've talked to a number of gear manufacturing technology providers to give you a sneak peak of what you can expect to see if you attend this year.

Skiving will be front and center when the gear industry comes together in Columbus this October. Attendees will find dedicated skiving equipment, multifunctional machines with skiving options and a slew of new cutting tools, machine designs and modifications to make the process more efficient and robust.

Grinding of bevel and hypoid gears creates on the surface a roughness structure with lines that are parallel to the root. Imperfections of those lines often repeat on preceding teeth, leading to a magnification of the amplitudes above the tooth mesh frequency and their higher harmonics. This phenomenon is known in grinding and has led in many cylindrical gear applications to an additional finishing operation (honing). Until now, in bevel and hypoid gear grinding, a short time lapping of pinion and gear after the grinding operation, is the only possibility to change the surface structure from the strongly root line oriented roughness lines to a diffuse structure.

Revolutionary new inspection technologies are helping gear manufacturers develop and produce more complex, higher quality gears in a fraction of the time it used to take.

Ground bevel and hypoid gears have a designed motion error that defines parts of their NVH behavior. The surface structure is defined by the hard finishing process.

How difficult is it to design a gear? It depends upon whom you ask.

Manufacturers focus on tool design, materials, coating, machine tool options and cutting parameters.
