Hardened and ground gear has two types of shaft arrangements. They can
be parallel shaft type or hollow shaft type. Hardened and ground gear
delivers a maximum hob rotation and table rotation with excellent
machining accuracy. Hardened ground gear provide a noise free and long term operation.
They are characterized by high output, easy operation and precise
machining. They offer rigidity, strength and high resistance to shock
load. They are available in a wide range of sizes and gear ratios.Hardened gears are used in several essential machine tools like wheels, bedways, etc. and are widely used in the aerospace industry.
