Applications & Materials
The Fuji Super F-II is a versatile powerhouse suitable for General Steel, Cast Iron, and Heavy Fabrication.
Common Industrial Uses
Weld Seam Removal: Fast leveling of high-tensile welds.
Edge Deburring: Smooth preparation of cut steel edges.
Foundry Work: Heavy-duty gate removal and fettling.
Surface Prep: Removing rust and scale before painting.
Frequently Asked Questions (FAQ)
What does "BF" mean in the specification?
BF stands for Resinoid Bond with Fiber reinforcement. This means the wheel contains internal fiberglass mesh layers to prevent shattering under side-load or stress, ensuring maximum safety.
Can I use this 7-inch wheel on a 9-inch grinder?
No. You should always match the wheel size to the grinder size. Using a smaller wheel on a larger grinder may exceed the wheel's maximum RPM rating (7,600 RPM), which is dangerous.
Is this wheel suitable for aluminum?
For aluminum, we recommend specialized wheels designed to prevent clogging (loading). While the Super F-II can grind aluminum, it is optimized for ferrous metals like steel and iron.
Choosing the correct abrasive wheel is critical for both operational efficiency and JIS-compliant safety. Fuji Grinding Wheels are engineered with precise technical markings to ensure the perfect match for your specific material and machine requirements.
Understanding Fuji Markings (e.g., WA 36 P BF)
Abrasive Type (WA/A/AZ): Determines the suitability for material hardness (e.g., WA for hardened steel, AZ for heavy-duty alloys).
Grit Size (16 - 120): Indicates the coarseness. Lower numbers for rapid removal; higher numbers for precision finishing.
Hardness Grade (L - S): Defines the bond strength. Correct selection prevents premature wheel wear or surface glazing.
Bonding Agent (BF): High-grade Resinoid bond reinforced for high-speed safety and impact resistance.
💡 Expert Selection Tip
For professional export markets, always verify the Peripheral Speed (m/s) compatibility. Fuji wheels are designed to exceed JIS Burst Speed factors, but operating at the recommended R.P.M. ensures the longest tool life and cleanest cut.
Note: Mismatched grit or hardness can lead to excessive heat buildup, affecting the workpiece's structural integrity.

Global Maintenance Standard: To maintain the high safety factor of Fuji wheels, avoid exposure to excessive humidity and chemical solvents during storage. Proper care preserves the resinoid bond's strength, crucial for high-load industrial applications.
Fuji products are manufactured following strict Japanese standard process requirements. Every wheel is engineered to meet or exceed JIS (Japanese Industrial Standards), such as JIS R 6242 and B 4051. Our core engineering logic prioritizes maximum operator protection by maintaining safety factors and burst speed capabilities that often surpass the highest industry benchmarks.

Efficiency Focused: Relies on machine guarding and operational procedures.
1.RPM Compliance: Never exceed the maximum R.P.M. specified on the wheel. Using the sides of the wheels for grinding is strictly prohibited, as it compromises the structural integrity of the abrasive bond.
2.Mandatory Idling: Allow the tool to idle for one minute before beginning work. If a new wheel has been mounted, an idle run of three minutes is required to ensure dynamic stability.
3.Workpiece Stability: All materials must be securely fastened. Improperly secured workpieces can lead to vibration, wheel binding, and unsafe kickback forces.
4.Arbor Hole Integrity: Do not modify or enlarge the metal center of the arbor hole. A proper fit is critical; a mismatched arbor causes eccentric rotation and dangerous vibration levels.
5.PPE Requirements: Industrial-grade face and eye protection are mandatory at all times. Ensure all protective gear meets local safety compliance standards.
6.Guard Protection: Protection guards are designed to contain fragments in the unlikely event of a wheel failure. Never operate tools or machinery with guards removed.

Professional Export & Maintenance Insight
When deploying Fuji high-performance tools in overseas markets, ensure that the regional power grid frequency and voltage match the tool specifications. To maintain the superior burst speed safety of Fuji wheels, store abrasives in a dry, temperate environment. Humidity can degrade the resin bond, potentially lowering the wheel’s resistance to centrifugal forces.
