Why Choose the 180mm Super F2 Grinding Wheel?

Affordable Steel Grinding

Aluminum oxide abrasive provides a practical balance of grinding performance and purchase cost for carbon steel, general steel and suitable cast iron applications. Select the grade to match your workload rather than paying for a specialized abrasive where it is not needed.

Warm-Press Manufacturing

FUJI’s warm-press process combines abrasive grains and phenolic resin under controlled manufacturing conditions. Together with subsequent curing, this process supports bond consistency, structural integrity and stable product quality.

Reinforced Wheel Construction

Alkali-free fiberglass mesh reinforces the resin-bonded wheel. This construction supports the wheel during its intended grinding operation, with correct selection and use remaining essential to safe performance.

Japan Quality Control

Production in FUJI’s own factory provides direct control over materials, manufacturing and inspection. Japanese quality management standards support consistency for repeat industrial orders and application-specific development.

Packaging 25 pieces per inner box / 50 pieces per carton. Confirm packaging for custom specifications when ordering.

Select the Thickness, Grit & Hardness for Your Work

Both 6mm and 7mm thicknesses are available. Select the thickness together with the wheel grade, grinder capacity and access around the workpiece. A thicker wheel contains more abrasive material, but service life and removal rate also depend on the formulation, applied pressure and grinding conditions.

36P: Balanced Grinding Feel

Grit 36 with grade P hardness is a commonly used Japanese specification. Compared with 24S, it uses a finer abrasive and a softer bond grade, making it a useful starting point when grinding feel and control are priorities.

24S: Coarser, Harder Grinding

Grit 24 with grade S hardness provides a coarser, harder specification for more aggressive material removal. It may produce a rougher grinding feel and greater vibration, depending on the machine, workpiece and operator pressure.

Custom options: FUJI can adjust grit, hardness, formulation and dimensions to suit your material and production conditions. Share your current wheel, equipment and the improvement required so that a suitable trial specification can be proposed.

Applications in Steel Fabrication & Industrial Maintenance

The 180mm wheel suits jobs where a compatible 7-inch grinder is preferred for sustained material removal over larger working areas. Typical applications include:

  • Weld grinding: Leveling welds and removing excess weld metal on steel assemblies.
  • Edge preparation and deburring: Preparing plate edges and removing burrs from suitable metal components.
  • Shipyard and structural fabrication: Grinding steel plate, frames and welded structures.
  • Maintenance and casting cleanup: General steel maintenance and suitable cast iron grinding tasks.

For demanding foundry casting applications where a zirconia abrasive is preferred, consider the 180mm FUJI Super Z grinding wheel for heavy-duty castings . Select between Super F2 and Super Z according to the casting material, grinding workload and the cost per completed part.

Frequently Asked Questions

How should we compare 36P and 24S for production grinding?

Test both grades on the same material using the same grinder and comparable operating conditions. Record grinding time, wheel consumption, finished surface and operator feedback. 24S is coarser and harder, but the better production choice is the grade that delivers the required result at an acceptable cost per part.

What should we specify for continuous weld grinding?

Provide the steel grade, weld condition, grinder model and speed, required dimensions, and current wheel specification. Explain whether your priority is removal rate, service life, grinding comfort or surface finish. These details help FUJI select between standard grades or propose a modified formulation.

When should a foundry consider Super Z instead of Super F2?

Super F2 is an affordable aluminum oxide option for general steel and suitable cast iron grinding. Consider Super Z zirconia grinding wheels when evaluating more demanding casting cleanup or sustained stock removal. A production trial should determine whether the change reduces grinding time or abrasive cost per casting.

Can the 72m/s wheel be used on equipment requiring an 80m/s wheel?

No. Order the separately rated 80m/s specification and check the maximum RPM marked on the supplied wheel against the grinder’s rated speed. A custom speed specification is a different supplied wheel rating, not permission to run a 72m/s wheel faster.

Which wheel should we choose for aluminum components?

Use a formulation selected for aluminum rather than assuming this general steel grinding wheel is suitable. FUJI offers a 125mm aluminum grinding wheel for aluminum fabrication. Provide the alloy and application requirements when discussing other dimensions or custom options.

Selection & Safe Use

Confirm wheel dimensions, mounting compatibility and marked maximum speed before use. Follow the wheel instructions and grinder manual, and use the correct guard and protective equipment. Request applicable safety documentation for the exact specification supplied.

Abrasive Wheel Selection & Technical Parameters Guide

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.

Fuji Abrasive Technical Selection Chart

Fuji Abrasives Wheel Description of Marking

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 Industrial Quality & Safety Protocols

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.

Standard Region Safety Factor (Burst Multiplier) Safety Logic & Benchmark
FUJI (High Precision) > 2.0x Engineered to exceed JIS requirements for maximum reliability.
Japan (JIS R 6242) 2.0x Extreme Safety: A wheel rated at 80m/s must withstand a 160m/s burst test.
Europe (EN 12413) 1.73x Risk Balanced: Provides high safety redundancy for most industrial apps.
USA (ANSI B7.1) 1.5x Efficiency Focused: Relies on machine guarding and operational procedures.

⚠️ Essential Safety Cautions & Operational Integrity

  • 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.
