EXTERNAL TO INTERNAL GEAR GRINDING IN 30 MINUTES OR LESS Based on Liebherr's Opal system, the IG Opal 4.0 internal geartooth profile-grinding technology fits a belt-drive spindle to the company's standard GH 4.0, GH 5.0 and GH 6.0 grinding heads. The internal gear-grinding arm will be available in two sizes at first, with more to follow. The company also takes requests for custom internal gear- grinding arms. This technology is said to enable switching from external to internal grinding in half an hour at most. The user detaches the external gear grinding disc or worm, hangs the internal gear grinding arm on the hardened stop bars to ensure repeat accuracy, and fixes it in place with screws. After tensioning the belt-drive disc and the belt, internal gears can be ground using a grinding disc 100 or 125 mm in diameter. IG Opal 4.0 func- tions at a maximum s p i n d l e s p e e d o f 12,000 rpm. A larger version, the IG Opal 4.1, features a maxi- mu m g r inding disc diameter of 125 mm. Both arms have been suc- cessfully tested using cubic boron nitride (CBN) and corundum discs. Dressable wheels can be tended by the same dresser used for external gear grinding. All internal gear grinding arms are modeled in 3D and can be used in very confined spaces.
