During our interactions with customers, we find the common challenge faced by customers about getting incorrect component parameters using corrected lead hobs. To address the challenge, we will talk about what corrected lead hobs are, why it is necessary to design such hobs, and how to set up the hob on the machine depending upon the type of hobbing machine (manual, semiautomatic CNC, or CNC).

Sandvik Coromant, has earned the 2022 IndustryWeek Best Plants Award for its Westminster, South Carolina, production site. The award is given to North American manufacturing plants that lead their industries in outstanding operational excellence, customer service and employee engagement.

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).

Sandvik Coromant has appointed two new members to its management group. Michael Eneberg began his new role as vice president and head of global sales on May 1, 2022, while Nicolas Dellachiesa will join as head of merger and acquisitions (M&A) in June. Reporting to Sandvik Coromant President, Helen Blomqvist, both Eneberg and Dellachiesa will play vital roles in driving the company’s global growth forward.
