4A2 Diamond Grinding Wheels

Reliable 4A2 Resin Bond Diamond Wheels for Carbide Tool Grinding & Resharpening

Restore peak cutting performance to your essential Tungsten Carbide cutting tools with ZYsuperhard’s 4A2 Resin Bond Diamond Grinding Wheels. Specifically designed for precision grinding and resharpening operations typically performed on universal tool grinding machines, these wheels offer an effective and economical combination of sharp cutting action, good surface finish capability, and reliable durability. They are a staple choice for tool rooms, regrinding services, and manufacturing facilities focused on maintaining carbide tooling.

The Resin Bond Advantage for Carbide Tool Grinding:

Our carefully formulated resin bond system is optimized for grinding hard and brittle Tungsten Carbide, providing key advantages:

• Free-Cutting Action & Reduced Heat: The bond characteristics promote a cooler grinding process by reducing forces and minimizing heat generation. This is crucial for protecting the sensitive carbide cutting edge from thermal damage, micro-cracking, or loss of hardness during sharpening.
• Good Surface Finish: Resin bonds naturally help achieve smooth, clean finishes on the ground flanks and faces of carbide tools, contributing to improved cutting performance and extending the life of the resharpened tool.
• Adaptability & Ease of Use: Offers a degree of conformability, ensuring good contact between the wheel and the tool’s geometry, which is beneficial during manual or semi-automatic grinding operations often performed on universal machines.
• Cost-Effectiveness: Provides excellent value by balancing effective grinding performance with reasonable wheel life, making it a practical choice for general-purpose carbide tool maintenance and sharpening tasks.

Key Features:

• Versatile 4A2 Shape: This standard recessed one side straight wheel shape (ISO Type 4A2) allows for flexibility in various grinding operations on universal tool grinders, including peripheral grinding of diameters and face grinding of tool ends or features.
• High-Quality Diamond Abrasive: Utilizes appropriately selected diamond grits (available in standard sizes like D64, D76, D126 and others) optimized for efficient material removal and achieving desired edge quality on hard Tungsten Carbide.
• Precision Manufacturing: Manufactured to ensure good wheel balance and dimensional accuracy, promoting stable and consistent performance on your grinder.

Core Applications:

Ideal for grinding and resharpening a wide variety of Tungsten Carbide cutting tools using universal tool and cutter grinders. Common applications include:

• Carbide Milling Cutters: Resharpening cutting edges on end mill flutes (face/periphery), side-and-face cutters, and slot drills.
• Carbide Reamers: Regrinding lead chamfers and flute faces.
• Carbide Turning Tools & Inserts: Sharpening cutting edges, faces, and radii.
• Carbide Drills: Regrinding point angles and facets (within the geometric capabilities of the 4A2 wheel shape and machine setup).
• General tool maintenance, modification, and reconditioning tasks performed in tool rooms, machine shops, and specialized regrinding facilities.
