   Grinding is an important method of gear machining, grinding processing and utilization process of gear tooth grinding machine called grinding. Is divided into inner and outer tooth grinding teeth grinding of cylindrical gear; internal gear grinding and gear grinding cone gear, bevel gear, grinding. Gear grinding machine, grinding machine, is a kind of gear finishing with metal cutting machine tool. With grinding wheel as the gear tooth cutter to grinding has processed surface, is used to improve the precision of gear and surface finish, this processing method is called “ grinding ”. Applicable to steel material of high hardness of gear finishing after quenching. Is a kind of gear finishing with metal cutting machine tool. With grinding wheel as the gear tooth cutter to grinding has processed surface, is used to improve the precision of gear and surface finish, this processing method is called “ grinding ”. Applicable to steel material of high hardness of gear finishing after quenching. Gear classification and terminology classification: the transmission ratio constant transmission ratio — — circular gear mechanism (cylindrical, conical)
   Its main characteristic is that it can serve as the final process of hard gear, gear and comprehensively correct each error before grinding, machining accuracy, higher therefore, gear manufacturing, gear grinding is a processing method widely used.
   People study the grinding problem are generally from the research about the gear grinding, gear grinding process parameters selection, a grinding wheel gear grinding speed, feed speed, grinding allowance (grinding allowance) etc.. According to the properties of the abrasive wheel is divided into oxide, carbide grinding wheel grinding wheel system and super hard abrasive grinding wheel. Because be grinding gear material usually always thermal nitriding treatment of various types of materials, so the general choice of diamond alloy wheel, in order to improve the production efficiency, the production of high precision gear.
