hardness of the workpiece may cause burns hard

EFD slewing gear induction hardening and wind power technology exchange will be held in Shanghai
October 13, 2009 "EFD slewing bearing gear induction hardening technology exchanges" in EFD Induction Equipment (Shanghai) Co., Ltd. held. From domestic and wind power in large slewing gear processing industry's leading manufacturing companies on behalf of a total of more than 50 people participated in the exchange.
German companies from EFD slewing product applications manager Helmut Schulte President made ​​a presentation on "slewing bearing / gear induction hardening technology and application" report. During the meeting delegates also to EFD Induction Equipment (Shanghai) Co., Ltd. conducted a site visit, the delegates with EFD's technical staff to do in-depth exchanges on clutch bearing of some of the EFD's customers and other representatives also shared their production experience.It is understood that substandard products, there are 17 kinds of grinding wheels with cymbals, fiber-reinforced resin cutting wheel, grinding wheel and resin ceramic flat flat grinding wheel diameter substandard products, wheel diameter is too large or too small will result in the course of grinding wheel rupture. 4 kinds of ceramic flat-shaped grinding wheel hardness failed. The hardness of the cutting wheel, grinding plays a key role in the efficiency of the grinding wheel hardness soft and hard grade, to the material of the workpiece and being adapted to the hardness of soft efficiency is not high; hardness of the workpiece may cause burns hard
