| 개요 | ● More and more helical gears are being used as motor vehicle transmissions with a greater range
of gears (from 5 speed to 6, 7 or 8). ● Process to manufacture helical gears and pinions in a cost effective manner needs to be developed. Increasing demand for transition from cutting to precision forging. ● The present technology is about ensuring that helical gears for motor vehicle transmissions are formed precisely using cold precision forging. ● Now dimensional precision can be achieved through process design, mold design, processing technology and mold durability. |
