The KNG 350 flex is based on a compact, set-up-optimised machine concept for use in the prototype sector up to large series production. Both externally and internally toothed workpieces can be machined. The performance-optimised grinding spindle with counter bearing is designed also for the use of large grind-ing worms with widths of up to 200 mm. This allows an efficient realisation, especially when machining of components with large modules and using 2-sector worms for fine grinding or polishing applications. From manual loading to a comprehensive automation solution, the concept offers full flexibility. The functional and ergonomic machine design paired with the innovative user-friendly interface KN grind supports the user during set-up and optimisation of grinding projects. Due to the use of auxiliary spindles small grinding wheels can be applied. Both involute internal gears and special profiles can be machined with the internal grinding device.
