Product Overview: Fuji FS Series Wet Metal Cut-Off Machines
The Fuji FS B6/B7E/B8E/B9E series represents the pinnacle of innovation in stationary metal cut-off machines. Engineered for professionals who demand precision, these machines integrate seamlessly with Fuji's ultra-thin cut-off wheels to create a complete high-precision cutting system.
Unlike conventional dry cutting that generates hazardous sparks and dust, the Fuji FS series utilizes advanced wet cutting technology. By continuously applying coolant, this system eliminates flying sparks, suppresses dust, and maintains optimal cutting temperatures. The result is an exceptionally clean, smooth, and burr-free surface finish that often eliminates the need for secondary processing.
Whether cutting general steel, carbon steel, or alloy steel (25-40mm diameter), the Fuji FS series delivers consistent performance rooted in rigorous Japanese industrial standards.

Technical Highlights & Core Advantages
1. Specialized Cutting System Integration
These machines are not generic cutters; they are specifically calibrated for Fuji Ultra-Thin Cut-Off Wheels. The motor torque and RPM are optimized to work with wheels as thin as 0.5mm, ensuring minimal material loss (kerf) and maximum cutting speed.
2. Advanced Wet Cutting Technology
The integrated coolant system prevents the "heat-affected zone" (HAZ) common in dry cutting. This preserves the metallurgical integrity of the workpiece and prevents hardening at the cut edge, which is critical for subsequent machining or welding.
3. Enhanced Workplace Safety
Spark-Free: Safe for use in environments where fire hazards are a concern.
Dust Suppression: Captures fine metallic particles in the coolant, keeping the air clean.
We provide a comprehensive setup to get you started immediately. The optional operation desk and high-capacity cooling tank allow for a customized workstation layout.
Industrial Applications
The Fuji FS B6-B9E series is the preferred choice for industries requiring high precision and safety:
Metallurgical Laboratories: For cutting test samples without altering the grain structure due to heat.
Electronics & Medical Device Mfg: Precise cutting of small diameter stainless steel tubing and exotic alloys.
Tool & Die Making: Cutting hardened steel ejector pins and punches with exact length tolerances.
General Fabrication: efficient processing of structural steel with zero burrs.
Frequently Asked Questions (FAQ)
Q1: Does this machine require special coolant?
A: We recommend using water-soluble coolant designed for ferrous metals. This ensures optimal cooling, rust prevention for the machine, and easy cleaning of the workpiece.
Q2: Can I use this machine for dry cutting?
A: No. The FS series is designed exclusively for wet cutting. Running it dry may overheat the thin wheels, leading to breakage and poor cut quality.
Q3: How often should I change the coolant?
A: For daily operation, we recommend checking coolant levels daily and replacing the fluid every 3-6 months to prevent bacterial growth and maintain cooling efficiency.
Q4: What is the benefit of using ultra-thin wheels?
A: Ultra-thin wheels (0.5-1.5mm) remove less material, which means less resistance, faster cuts, lower power consumption, and significant material savings over time.
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.
