Product Overview: Why Professionals Switch to JITAN

The FUJI JITAN Grinding Wheel is not just another abrasive disc; it is a solution to the three biggest pain points in metal fabrication: rapid wheel wear, workpiece overheating, and excessive dust.

Engineered under strict JIS (Japanese Industrial Standards), JITAN features an exclusive Self-Sharpening Zirconia Formula. Unlike standard aluminum oxide wheels that dull quickly, JITAN grains fracture cleanly to expose new, sharp cutting edges continuously. This "self-sharpening" effect ensures consistent material removal rates (MRR) from the first spark to the last.

Ideal for Automotive, Aerospace, Shipbuilding, and Heavy Machinery industries, it excels on challenging materials like Stainless Steel (Inox), Cast Iron, and Superalloys.

Unmatched Advantages in Grinding Performance

1. Superior Durability (The 1/3 Wear Rule)

JITAN redefines cost-efficiency. In controlled laboratory tests against leading global competitors:

On Carbon Steel (SS400): Demonstrated only 1/3 the wear while removing 3x more material.
On Stainless Steel (SUS304): Showed just 1/4 the wear, significantly reducing downtime for wheel changes.

2. Cool-Cut Technology (Heat & Dust Reduction)

Heat is the enemy of stainless steel. JITAN's unique bonding agent reduces heat buildup by 40%, preventing "blueing" or thermal discoloration. Additionally, it cuts dust emission by 60%, creating a cleaner workshop environment compliant with modern safety standards.

3. Low Vibration Ergonomics

Engineered with precision balancing, JITAN keeps vibration acceleration below 0.5g. This protects operators from Hand-Arm Vibration Syndrome (HAVS) and allows for smoother, more precise control during delicate blending tasks.

Industry Applications: Where JITAN Excels

The FUJI JITAN wheel is engineered for industries that demand speed and surface quality:

Food Processing & Pharmaceutical (Stainless Steel): The "Cool-Cut" capability prevents heat tinting on sanitary stainless steel tanks and pipes, eliminating the need for post-weld pickling or extensive polishing.
Shipbuilding & Marine (Heavy Steel): Capable of removing heavy weld beads on ship hulls rapidly. Its durability means fewer trips to the tool crib for replacement wheels.
Aerospace & Energy (Superalloys): Maintains aggressive cutting bite even on work-hardening nickel alloys and exotic metals.
Foundry (Cast Iron): Excellent for gate removal and surface conditioning of cast parts without clogging (loading).

Frequently Asked Questions (FAQ)

Q: How does Zirconia differ from standard Aluminum Oxide wheels?

A: Zirconia Alumina is tougher and more heat-resistant. While Aluminum Oxide dulls and rubs, Zirconia micro-fractures to self-sharpen. This makes JITAN last 3-4x longer and cut faster, especially on hard metals.

Q: Is JITAN suitable for grinding Aluminum?

A: Yes. The specialized bond helps prevent "loading" (clogging) which is common with soft metals like aluminum, although it excels primarily on steel and stainless steel.

Q: Can I use the 3mm JITAN wheel for cutting?

A: The 3mm wheel is designed as a "Flexible Grinding Wheel" for light blending and surface finishing. For cutting or heavy stock removal, we recommend the 6mm version or our dedicated Cutting Discs for safety.

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 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.

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.
