HIGH SPEED STEEL HOBS

Efficient Cutting Tools

High-speed steel Hobs are high-precision cutting tools and used in machine cutting processes for gears where more than one gear needs to be cut. These hobs are also noted for their long life as well as for their immunity to wear at sharp cutting edges, even at high speeds. The extraordinary material properties of the Hobs enable them to tolerate the extreme heat generated from today’s high-speed machinery, making them suitable for cutting hard and abrasive materials like steel, aluminum, and other alloys.

These hobs are available in different dimensions for making spur gears, helical gears, bevel gears and many others. They are carefully designed with multiple teeth for even cuts, producing high quality product for gear cutting applications. For either mass or single production, complexes or simple gear cutting operations, High-Speed Steel Hobs are the optimal solution that guarantee excellent results in production.

Why Choose High-Speed Steel Hobs?

Classification Of High-Speed Steel Hobs

1. Classified By Gear Type
  • Spur Gear Hobs: Spur gear hobs have a straight cutting face and shave the periphery of the wheel.
  • Helical Gear Hobs: With a helical cutting face, these hobs are ideal for dealing with helical gears and cutting them concisely and smoothly.
  • Spiral Bevel Gear Hobs: Hobs with a helical cutting face that matches the tooth shape of spiral bevel gears and which are specifically used for cutting spiral bevel gears.
2. Classification By Processing Object
  • Steel Hobs: Manufacturing from high-speed steel, these hobs are used for cutting hard metals like steel. They have high hardness, wear resistance, with stable cutting performance under high-speed cutting, which guarantees the precision processing and dimension control.
  • Aluminum Hobs： These specialized hobs are used to cut soft metals such as aluminum alloys. They maximize processing efficiency and productivity while generating minimum heat when cutting. It is to minimize the distortion of aluminum stock and equipment wear.

High Speed Steel Gears Hobs are the basic tool for manufacturing gears in various industries due to their long life and the highest range of cutting performance. HSS hobs are suitable for application in the automotive, aerospace, railway, and heavy machinery industries. They provide excellent performance, improved productivity, and tools life. Adding HSS hobs to your machining operations can lead to increased part quality and a reduction in overall costs.
