Gleason has introduced a next-generation 150SPH power honing machine that uses the latest Gleason patented Spheric® honing process to finish hardened spur and helical gears up to 150 mm in diameter in as little as half the time required by existing machines. The 150SPH is well suited for production environments requiring higher volume finishing of high precision gears with low noise characteristics, of the type increasingly found in many of today’s transmission applications. Equipped with a high speed direct-drive honing head, the 150SPH is capable of honing at speeds almost twice as fast as commonly used in practice today. It employs Gleason’s patented Spheric honing process, a combination of Gleason proprietary software and powerful Siemens 840D CNC that enables the user to produce quieter gears faster by improving tooth geometry, reducing concentricity and indexing errors and optimizing overall tooth flank contact characteristics.
