中文摘要：

针对国内硬齿面齿轮的加工现状，研制了数控成形磨齿机。床身采用整体铸造结构，刚性好。机床采用动柱式结构和可转位的砂轮架，扩大了机床的工艺范围，实现了机床的“一机多能”。机床上安装有成形砂轮修整装置，解决了成形砂轮在机修整问题。

英文摘要：

Aiming at the machining status of gear with hard face, CNC gear form grinding machine is developed. With integrated casting bed, the machine has good rigidity. The machine is designed with a movable pillar and an indexing grinding head, thus enlarging its process scope. The form wheel dressing on line is realized by installing a dressing device on the machine.
