This paper is divided into two parts. The first part is a general digression on the pressure angle on cylindrical gears. The pressure angle is a variable that plays an important role in defining the geometry of gears and hobs, yet it is not widely discussed. This introduction serves as a prerequisite for the second part of the paper. The second part will show an application case of hoosing
the most suitable hob to cut a given gear. In this selection process, particular attention will be paid to the pressure angle of the hob for cutting with modified rolling, i.e., with a reduced pressure angle compared to that of the gear.
Gear cutting has witnessed remarkable advancements over the years, with modern technologies transforming traditional methods into streamlined, highly efficient processes. NIDEC’s tools and methodologies increase productivity and quality in manufacturing. This article delves into the technological innovations, market relevance, and advantages of their gear-cutting solutions.
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).
Bourn & Koch, Inc. of Rockford, IL, is pleased to report that Ross Wegryn-Jones has recently joined the company as our National Sales Manager. Ross will be responsible for the sales of gear manufacturing machines, precision grinding machines, and specialty machine tools for unique manufacturing applications. This includes Bourn & Koch horizontal gear hobbers; Fellows gear shapers; Blanchard rotary surface grinders, and Bourn & Koch’s new MT3 vertical grinding machine.
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.

Our company manufactures a range of hardened and ground gears. We are looking into using skiving as part of our finishing process on gears in the 4-12 module range made form 17 CrNiMO6 material and hardened to between 58 and 62 Rc. Can you tell us more about this process?
