Industrial 6-inch Resin Diamond Cup Wheel | Shape Type 6A2

Key Features & Benefits

• Selected High-Quality Diamond Abrasive: Features carefully selected, high-grade synthetic diamond particles. The sharp, strong, and thermally stable abrasive ensures powerful grinding force and consistent, efficient cutting performance over the life of the wheel.
• Advanced Resin Bond Formula: Utilizes a high-performance resin bond with excellent self-sharpening properties and elasticity. This prevents workpiece burning, absorbs grinding vibrations, and helps achieve a superior surface finish, potentially reducing the need for subsequent polishing steps.
• Professional Dynamic Balancing Control: Each wheel undergoes strict dynamic balancing control before shipment. This ensures stable, low-vibration operation at high speeds, which protects your machine’s spindle and is critical for achieving high-precision machining results.
• Lightweight & High-Strength Body: Designed with a lightweight yet robust body that reduces the load on the machine spindle. This design also aids in rapid heat dissipation, contributing to a more stable and effective grinding process.

Primary Applications

Engineered for a range of high-precision grinding tasks, our wheels provide solutions across multiple industries. Applications are broadly categorized into two main types:

1. Manufacturing & Regrinding of Cutting Tools

This is the primary application, focusing on creating and restoring the sharp, precise geometry of various cutting tools.

• Solid Carbide (Tungsten Carbide) Tooling: Used for manufacturing new tools (end mills, drills, reamers) and regrinding them to extend their service life.
• Superabrasive Tooling (PCD & PCBN): Essential for the precision finishing of Polycrystalline Diamond (PCD) and Polycrystalline Cubic Boron Nitride (PCBN) cutting edges.
• Specialized & Other Tooling: Includes the sharpening of alloy milling cutters and the precision grinding of specialty blades, such as those used for PCB V-cutting.

2. Grinding of High-Wear Industrial Components

Beyond cutting tools, this wheel is ideal for the surface and form grinding of durable components made from hard, brittle materials.

• Ceramic Components: Grinding of high-performance ceramic parts used in aerospace, medical, and semiconductor applications.
• Wear Parts: Finishing of tungsten carbide or cermet components like seals, nozzles, and guides that require high wear resistance.
• Magnetic Materials: Shaping and finishing of hard magnetic components for motors and sensors.

Target Materials

Excels at grinding a wide range of hard and brittle materials, including but not limited to:

• Tungsten Carbide (WC): All grades of cemented carbide.
• Advanced Engineering Ceramics: Such as Alumina (Al₂O₃), Zirconia (ZrO₂), and Silicon Nitride (Si₃N₄).
• PCD (Polycrystalline Diamond) & PCBN (Polycrystalline Cubic Boron Nitride) Composites.
• Magnetic Materials.
• Cermets (Ceramic-Metal Composites).

Custom Solutions

Guidelines for Use and Maintenance

I. Daily Operation Standards

• Installation & Balancing
  • Before mounting, inspect the wheel for integrity. Ensure it matches the spindle to prevent run-out. Perform dynamic balancing if necessary (imbalance amount ≤5g·cm).
  • Secure with a specialized flange, ensuring clamping force is uniform to prevent vibration and localized wear.
• Grinding Parameter Control
  • Rotational speed must not exceed the wheel’s maximum rated linear speed (typically ≤35m/s for resin bond wheels).
  • Use a moderate feed rate to avoid excessive cutting force, which can lead to wheel chipping or excessive wear.
  • Prioritize water-based coolants (e.g., emulsion) for temperature reduction to prevent high temperatures from causing resin bond failure.

II. Periodic Maintenance Measures

• Dressing & Cleaning
  • Every 8-10 hours, dress the wheel surface with a diamond dressing pen or roller to restore sharpness (recommended dressing feed: 0.01-0.02mm).
  • After dressing, clear metal chips from the wheel’s pores to prevent clogging (use compressed air or a specialized cleaning agent).
  • A White Aluminum Oxide (WA) oil stone can be used to dress resin diamond wheels, but note: the stone’s hardness must be lower than the wheel’s abrasive; apply light pressure and slow speed during dressing to avoid damaging the resin bond layer.
• Lubrication & Inspection
  • Add lubricating grease to the main spindle bearings every 3 months.
  • Check the wheel’s thickness for wear; it must be replaced when the remaining thickness is less than 1/3 of the initial value.

III. Storage & Environmental Requirements

• Store in a dry environment (humidity <60%) to prevent the resin bond from absorbing moisture and deforming.
• If unused for a long period, it is recommended to apply anti-rust oil to the wheel’s end face to prevent oxidation.

IV. Common Issue Resolution

• Wheel Glazing (Dullness): Immediately dress the wheel and check if the coolant flow is sufficient.
• Abnormal Vibration: Re-perform dynamic balancing or check the spindle bearing clearance (standard value: 0.01-0.03mm).

Following these methods can extend the grinding wheel’s lifespan by 30%-50% while ensuring processing accuracy and safety.
