Abstract
The process for making worm gears introduced here is the process performed by our GALAXY form rolling machine. Electric Power Steering has good reputation never the less it has a high cost. The worm gear it requires is processed, currently by milling and grinding. We expect our research to contribute to economical production by cutting costs. Form rolling costs about 40% less than the cost of cutting. Our new genuine computer control GALAXY -the only one fully utilizing computer capacities- succeeds in economical and precise form rolling of hi-tech worm gears.
