3A1 / 1A1-CB Diamond Wheels

3A1 / 1A1-CB Diamond Wheels are precision grinding tools commonly used for carbide, ceramics, glass, quartz, and other hard-to-grind materials.

1A1-CB Diamond Wheels

• Shape: Standard flat grinding wheel with straight sides.
• Use: ID grinding
• CB: Counter/bore
• Advantages: High precision, sharp cutting, and versatile for ID, and face grinding.

3A1 Diamond Wheels

• Shape: Standard flat grinding wheel with straight sides.
• Use: ID grinding
• Hub and Counter/bore
• Advantages: Hub provides additional distance from spindle and deeper counter/bore for ID, and face grinding.

Resin Bond 3A1 / 1A1-CB wheels for ID grinding using resin (polymer) as the bonding matrix to hold the diamond particles.

3A1 / 1A1-CB Wheel Shape

• 3A1 Diamond Wheel has a hub and counter bore.
• 1A1-CB Diamond Wheel has a counter bore.
• 3A1 / 1A1-CB Diamond Wheels have relief for face grinding.

Resin Bond Features

• Bonding material: Synthetic resins with fillers to improve wear resistance or thermal properties.
• Cool cutting action: Resin bond provides lower grinding forces and less heat than metal bond.
• Good surface finish: Commonly used when a fine surface quality is required.
• Self-sharpening: Bond breaks down gradually, exposing new sharp diamond particles.
• Lower tool life vs. metal bond, but much higher grinding efficiency.

Applications

• Carbide tool grinding (cutters, inserts, drills).
• Ceramics and glass grinding (where precision and surface finish are important).
• PCD/PCBN tool sharpening (with high-concentration resin bond).
• Optical glass, quartz, sapphire (resin bond is softer, reduces cracking).

Advantages

• 3A1 / 1A1-CB Diamond Wheels are excellent for precision ID grinding.
• 3A1 / 1A1-CB Diamond Wheels have fast material removal rates.
• 3A1 / 1A1-CB Diamond Wheels will produce smooth finishes on hard materials.
