New tools for gear cutting
HORN's product portfolio comprises a wide range of tools to produce various gear tooth geometries of module 0.5 to 30. Whether this involves gear cutting for spur gears, shaft/hub connections, worm shafts, bevel gears, pinions or customised profiles, all these tooth profiles can be manufactured extremely cost-effectively with milling or broaching tools. Now, the new skiving tool range is yet more testament to the company's gear cutting expertise. It is a process that has been in use for over a century – but has only been incorporated into a wider range of applications since machining centres and universal machines with fully synchronised spindles and process-optimised software have been able to accommodate its highly complex technology.
Productive and cost-effective
The new range consists of tools for high-yield manufacturing of internal gear teeth, splines and other internal profiles as well as external gear teeth with interference. In these applications, the key advantages that skiving offers are significantly shorter process times in comparison to broaching, the ability to use the technique on optimised turning and milling centres, turning and gear cutting takes place in one set-up, the absence of undercuts at the end of the teeth, a manufacturing process that is generally more productive and cost-effective compared with gear shaping and broaching, and cycle times that are four to five times shorter than those found in broaching processes.
Skiving tools are designed for gear cutting in medium to large batches. Each tool is individually adapted to the application and to the material being machined, with the various tool interfaces based on the number of teeth and the module size.
