Product Details
Dressing Stone
White alumina dressing stones are professional tools specifically designed for dressing diamond grinding wheels. White alumina oil stones made with high-purity white fused alumina (WA) abrasive and a special ceramic binder, offer excellent cutting performance and shape retention capabilities, effectively removing the passivation layer on the grinding wheel surface and restoring its cutting performance and geometric accuracy. White alumina oil stones is widely used in tool grinding machines, precision grinding, and dressing grinding wheels.
Advantages of White alumina oil stones
* Efficient Dressing – Quickly restores the sharpness of diamond grinding wheels
* Precision Shaping – Accurately maintains the geometric shape of the grinding wheel
* Extended Lifespan – High-purity white corundum abrasive offers strong wear resistance
* Easy Operation – Suitable for both wet and dry applications, no professional skills required
* High Flatness – Special process ensures dimensional stability
* Economical and Environmentally Friendly – Reduces the frequency of grinding wheel replacement and lowers costs
Applicable grinding wheel types
* Diamond grinding wheels
* CBN grinding wheels
* Ceramic bonded grinding wheels
* Metal bonded diamond grinding wheels

User Guide
1. Installation and Fixing
Securely mount the honing stone onto the dresser, ensuring the dressing surface is parallel to the grinding wheel surface. A mounting angle of 5°-10° is recommended.
2.Parameter Settings
Recommended dressing parameters: feed speed 0.5-2 m/min, dressing depth 0.01-0.05 mm/pass, coolant flow rate ≥5 L/min.
3. Dressing Operation
Start dressing evenly from one end of the grinding wheel, maintaining a constant feed speed to avoid localized overloading.
4. Regular Inspection
Check the wear of the honing stone every 20-30 dressing cycles. Adjust dressing parameters or replace the honing stone as needed.
Professional advice: For the first dressing of a new grinding wheel, a 180# honing stone is recommended. For daily maintenance, use a 240# honing stone, and perform dressing every 4-8 hours of operation.
