3A1 / 1A1-CB CBN Wheels

3A1 / 1A1-CB Resin Bond CBN ID Grinding Wheel is a superabrasive tool designed for internal diameter (ID) grinding applications, where precision, surface finish, and tool life are critical.

• 1A1-CB: Is a straight wheel with a counter bore on one side for ID grinding.
• 3A1: Similar to 1A1-CB but with built in hub for ID grinding.

 

• Resin bond:
  • Provides a cool cutting action.
  • Produces excellent surface finishes.
  • Well-suited for precision grinding of hardened steels, high-speed steels, tool steels, and superalloys.
  • Shorter life compared to metal or vitrified bonds, but superior in terms of surface quality and reduced risk of burn.

 

• Super bond (Hybrid):
  • Excellent for spray materials.
  • Withstands higher thermal temperatures.
  • Grinds hardened steels, high-speed steels, tool steels, and superalloys.
  • Longer life compared to resin bonds, but superior in terms repeatability and reduced risk of burning.

 

 

• CBN (Cubic Boron Nitride):
  • Preferred for ferrous materials (hardened steel, bearing steel, tool steel, powdered metals, etc.).
  • Maintains sharpness and cutting ability under high heat.
  • Much longer life than conventional abrasives like aluminum oxide.

 

• Internal grinding of:
  • Bearing races
  • Injection nozzles
  • Hydraulic components
  • Aerospace parts
  • Tooling and dies
• Where tight tolerances, form stability, and fine surface finishes are required.

 

• High dimensional accuracy
• Excellent surface finish (mirror-like possible)
• Lower grinding forces = reduced heat & work piece damage
• Faster material removal compared to conventional abrasives
