Wälzfräser-Rohlinge

Cemented tungsten carbide hob blanks provide accurate, efficient, and productive cutting profiles customized for tools used for roughing and finishing gears.

Hob blanks are pre-formed, manufactured pieces of metal or other materials used as a starting point for producing various types of cutting tools, such as gear hobs, milling cutters, and broaches. Hob blanks are typically made of high-speed steel or tungsten carbide and are machined and shaped to create the specific cutting profiles required for the tool's intended use.

Hyperion Materials & Technologies manufacturers cemented carbide hob blanks designed for tools used in roughing and finishing gears and provides a wide range of hob blank grades for shell, shank, single shank, dual shank, straight fluted, spiral fluted, and chamfer hob blanks. Each grade uniquely benefits toolmakers, including reduced electrical discharge machining (EDM) wire cutting, wire cutting costs, and inventory needs while providing quicker lead times, longer tool life, less grinding for resharpening, and higher productivity.

Various metal cutting hobs blanks

Hob Blanks Applications

 

Once a gear hob blank is shaped, it can be heat-treated and finished to produce a high-quality cutting tool that is both durable and effective. Tool manufacturers use gear hob blanks to produce gear-cutting tools for creating various parts, such as gears for transmissions, aircraft engines, conveyor systems, printing presses, and more.

Hob blanks are typically used in developing these tools because of their ability to be customized to meet specific requirements. In addition, they are extremely precise, accurate, versatile, and durable, which ensures a prolonged tool life, reliable performance, and improved productivity.

These factors help produce high-quality gears, creating parts in the automotive, aerospace, industrial machinery, medical, and consumer products industries.

Frequently Asked Questions about Hob Blanks
