Large diameter gear cell released to production
GLI has released a large diameter gear manufacturing cell to production. This manufacturing cell is capable of turning, hobbing, automatic deburring, milling and drilling of crowned spur and helical gears up to 685 mm (27 inches) in diameter.
The organization of this cell allows for efficient processing of large gears by performing multiple operations simultaneously by a single operator. This improves quality and reduces lead times for large gears. |
