Description: All gear hob blanks are manufactured to custom dimensions in accordance with agreed solution. Cemented carbide grades and designs are tailored to each customer based on individual needs and requirements.
Hob Blanks Types
Hob blanks of cemented tungsten carbide grades are available for roughing and finishing operations in steels with hardness ranging from HRC30 to HRC65. Hyperion Materials & Technologies manufactures standard hob blanks in either a 12 teeth or a 15 teeth configuration.
We have developed cemented carbide hob blanks for demanding gear cutting and hobbing operations. Our hob blanks provide longer cutting life, better edge security, and higher productivity.
