FAQ:  

Q1.What materials can diamond grinding wheels grind?

Diamond grinding wheels are mainly used for grinding hard and brittle non-ferrous materials such as tungsten carbide, ceramics, glass, quartz, silicon, PCD/PCBN tools, stone, and composites. For ferrous steels, CBN grinding wheels are recommended instead.

Q2. How do I choose the right grit size?
• Coarse grit (60#–120#): Fast stock removal and rough grinding
• Medium grit (150#–240#): General sharpening and semi-finishing
• Fine grit (320#–1000#): Precision finishing and polishing

Finer grit gives better surface finish, while coarser grit improves grinding efficiency.

Q3. What bond type should I choose: resin, vitrified, metal, or electroplated?
• Resin bond: Sharp cutting, economical, ideal for tool grinding
• Vitrified bond: High precision, long life, excellent heat resistance
• Metal bond: Strong wear resistance for heavy-duty grinding
• Electroplated bond: Suitable for complex profiles and high-efficiency applications

Selection depends on workpiece material, grinding speed, and surface finish requirements.

Q4. Why does my grinding wheel burn the workpiece?

Possible reasons include:

• Incorrect grit size
• Excessive feed rate
• Insufficient coolant
• Wheel too hard for the application
• Wrong grinding speed

Using a sharper wheel with proper coolant can significantly reduce burning.

Q5. Can diamond grinding wheels be used for dry grinding?

Some resin bond and electroplated wheels support dry grinding, but wet grinding is strongly recommended for most precision applications because coolant reduces heat, improves surface finish, and extends wheel life.

Q6. Can you customize diamond grinding wheels?

Yes. Customized sizes, profiles, grit sizes, bond types, and arbor holes are available according to drawings or grinding applications. OEM and ODM services are commonly supported.

Q7. How can I improve the life of my grinding wheel?

Recommendations:

• Use proper coolant
• Avoid excessive grinding pressure
• Select suitable wheel speed
• Dress the wheel regularly
• Match the correct bond and grit to the material

Correct operation greatly improves grinding efficiency and reduces wheel consumption.
