Surface induction-hardening offers the possibility to selectively harden a component's raceway, while leaving the remainder of the component unaffected by the hardening process.

表面感应淬火提供有选择地淬硬部件滚道而部件的其余部分则不受淬火过程的影响的可能性。

Grinding hardening, the technology of hardening steel piece surface with grinding heat instead of high or medium frequency induction hardening heat, can integrate grinding surface hardening.

磨削强化处理技术是利用磨削热替代高、中频感应淬火热源对钢件表层进行强化处理，将磨削加工与表面强化合为一体。
