Workholding solutions increase throughput which generates uptime because they greatly reduce setup and changeover times. Operators can change workpieces in a highly repeatable manner which significantly increases the quality of the finished part. The primary function of streamlining production is to develop a workholding solution that optimizes the machining of multiple parts at once while maintaining tight tolerances. Below you will find a cross-section of companies that will be showcasing their approach to workholding systems at IMTS from Sept. 12–17 at McCormick Place in Chicago.
While the Greek proverb “the mills of the gods grind slowly, but they grind fine,” coined by Sextus Empiricus, was meant as a figurative expression of justice, it does hold true to gear grinding in the sense that there is a right way and a wrong way to do things because rushing the process only causes problems. Like justice, grinding takes the time it takes, but the grind is fine. So, the way to increase production, especially with the godlike largest gears, is to decrease nonproductive time with improved strategies.
Different component characteristics in electric vehicles lead to higher noise and load requirements in the automotive industry. E-mobility—to a certain degree—is changing how gear analysis and inspection is carried out. Dissecting noise issues in gears and gearboxes requires an analytical approach like a detective. The problem could stem from the design itself, tolerancing or tip/root relief issues, tooth flank form deviations like waviness or perhaps crowning issues that directly impact noise. Every aspect of gear production needs to be examined to provide the most accurate results.
It wasn’t long ago that cylindrical gear chamfering and deburring was almost an afterthought. Now the process ranks as high in importance as hobbing, shaping and grinding. Seemingly every gear manufacturer, particularly those developing transmission gears for e-drive applications, recognizes that anything less than a flawless tooth flank can result in premature transmission failure, less-than-optimal efficiency, and unacceptable noise. Thus, generating a chamfer to precise customer specifications is critical to minimize the potential for sharp, brittle edges after heat treat; avoid edge load situations in the gearbox; and eliminate excessive stock and hardened burrs in the tooth flank prior to the hard finishing operations (conditions which can greatly diminish tool life).
Southern Gear has added two rebuilt Gleason No. 102 Generators to its production capabilities to meet growing demand for smaller, high-precision straight bevel gears produced with the Coniflex process.
It’s that time of year again! Pandemic fears, supply chain issues, economic growth sprinkled in with some economic uncertainty. Every year, we take an in-depth look at the State of the Gear Industry and every year provides an interesting and colorful array of challenges, surprises and new innovations. Gear Technology spoke with Prasad Kizhakel, Chief Sales Officer at the Klingelnberg Group, Udo Stolz, Vice President of Sales and Marketing, Gleason Corporation, and Shane Hollingsworth, Vice President Sales at Kapp Technologies to assess what the next five years in gear manufacturing may look like from the machine tool providers
We asked what the future holds for workholding and the industry did not disappoint. All the machining trends such as automation, robotics, sensors, 3D-printed parts, etc. are finding their way into workholding equipment.
