Kennametal gear hob: once exceeded all expected tests

In addition, Reinhold Gesell, European Regional Manager for Custom Solutions Engineering at Kennametal added: “The larger the diameter of the gear, the wider the tooth width, the more economical it is to use the hob. Moreover, the customer saves a separate production step. For example, from roughing to finishing - until the entire process before heat treatment requires only one production step, and the average speed is significantly improved."

“From the beginning we have been concerned about whether our hobs can meet the highest productivity requirements, simple installation and use of structural friendliness” Rene Schumann, Kennametal Non-standard tool project manager said. “Therefore, we consistently adhere to the consistency of the center chip thickness in the design of the clip-on insert, resulting in very quiet, efficient and safe machining, and longer tool life. The cutting material is usually treated steel (18CrNiMo 7-6) It is a very fine-grained carbide with a novel PVD coating. This cutting material has been proven economically many times in other applications, while at the same time shortening the cycle of single-piece machining. Time, which results in a higher average speed."

The collaboration with Kennametal in this project went very smoothly. “First, we believe in the support of experts, flexible and fast delivery capabilities,” Maximilian van de Loo said. Heinz Wiechert found potential for improvement here, “There is no lifting hole for better transfer of the hob.” But Fürth's tool specialists satisfy the customer's wishes. “For us, after the tool delivery, the support did not end, we will continue to improve the process. Simply put, this is the goal of our complete service provider philosophy.” Michael Grimm, Director of the European Division of Advanced Engineering Road.

There will be many cooperation plans in the future - the combination of technology and innovation is the direction of our unremitting efforts, and we promise that there will be more new and interesting R&D.
