Available Bond Types & Their Applications

• Resin Bond

  • Ideal for precision grinding, fine sharpening, and finishing operations.
  • Provides self-sharpening properties, reducing grinding forces and improving efficiency.

• Metal Bond

  • Highly durable and wear-resistant, making it ideal for profile retention and heavy-stock removal applications.
  • Commonly used for hard materials like carbide, ceramics, and glass.

• Vitrified Bond

  • Offers high porosity for improved coolant penetration, reducing heat buildup and preventing workpiece burns.
  • Preferred for cylindrical and surface grinding of hardened steels and superalloys.

• Electroplated Bond

  • Provides maximum abrasive exposure, making it suitable for high-speed precision grinding and intricate profile shaping.
  • Ideal for one-off tool production and specialized applications.

Recommended Operating Parameters

• Grinding Speed – Typically 20–35 m/s, depending on bond type and workpiece material.
• Coolant Use – Strongly recommended (oil-based for carbide tool grinding, water-based for glass and ceramics) to maximize tool life and improve grinding performance.
• Feed Rate – Adjusted to maintain high-precision, low-damage material removal.
• Dressing Requirements – Minimal dressing needed, thanks to the self-sharpening properties of superabrasive grains.
