Material & Coating Excellence 

• Ultra-Fine Carbide Substrate: Crafted from ultra-fine grain carbide with a particle size of 0.6–1.0μm, bonded with 8–10% cobalt. This microstructure delivers exceptional hardness (92–94 HRA) and toughness, ensuring resistance to chipping and abrasion even in high-load milling.

• Advanced Coating Solutions:

• PVD Coatings (e.g., TiAlN): 3–5μm thick, featuring low friction coefficients (≤0.4) and high-temperature stability up to 900°C. Ideal for stainless steel and high-speed milling, reducing built-up edge (BUE) and extending tool life by 30–40%.

• CVD Coatings (e.g., TiCN/Al₂O₃/TiN): 5–8μm thick, providing superior wear resistance for steel and cast iron machining. Withstands oxidation up to 1,000°C, making it suitable for heavy-duty milling applications.

Core Advantages

• 90° Shoulder Milling Specialization: Engineered specifically for 90-degree shoulder milling, ensuring precise square edges (tolerance ±0.02mm) and consistent shoulder angles—critical for structural components and mold cavities.

• Three High-Positive Rake Edges: Features three active cutting edges with high-positive rake angles (+3° to +7°), reducing cutting forces by 15–20% compared to neutral-rake inserts. This minimizes machine vibration and workpiece deformation, ideal for thin-walled or delicate parts.

• Broad Material Compatibility: Efficiently machines steel (carbon, alloy), stainless steel (304, 316), cast iron (gray, ductile), and non-ferrous metals (e.g., aluminum alloys), eliminating the need for frequent tool changes across material groups.

• High-Speed Machining Capability: Optimized for high cutting speeds (180–350 m/min for steel; 150–300 m/min for stainless steel) and feed rates (0.15–0.4 mm/tooth), significantly boosting production efficiency and reducing cycle times.

• Enhanced Wear Resistance: The ultra-fine carbide substrate and protective coatings resist abrasive wear and edge rounding, reducing tool replacement frequency by 25–30% and lowering overall tooling costs.

• Precision Geometry for Quality Finishes: Specialized chipbreaker design and optimized cutting angles (clearance angles: 7°–11°) ensure smooth chip evacuation and fine surface finishes (Ra ≤ 1.6μm in semi-finishing operations), reducing post-machining polishing needs.

Applications

• Automotive Industry: Milling engine blocks, transmission housings, and suspension brackets from cast iron and alloy steel.

• Aerospace Manufacturing: Machining stainless steel structural parts and high-strength alloy components requiring tight tolerances.

• Mold & Die Making: Creating precise shoulders and cavities in mold bases, ensuring dimensional accuracy for injection molds and stamping dies.

• General Engineering: Processing steel and cast iron parts such as flanges, gears, and mechanical housings with 90° shoulder requirements.

Compatible Machines

• CNC Milling Centers: Vertical machining centers (Haas VF-series, Mazak VTC) and horizontal machining centers, paired with 90° shoulder milling cutters.

• High-Speed Machining Centers: Okuma HSC-series and DMG Mori HSC models, leveraging the inserts’ high-speed stability.

• Universal Milling Machines: Adaptable to both CNC and manual universal mills for small-batch production of shoulder-machined components.

Lifespan & Cost Efficiency

• Service Life: Under optimal conditions:

• 80–120 minutes of continuous milling per edge on steel.

• 60–90 minutes per edge on abrasive cast iron or stainless steel.

• Total lifespan across all 3 edges: 240–360 minutes, extended by advanced coatings and ultra-fine carbide.

• Cost Savings: Reduced tool change downtime and high edge utilization result in a 20–25% lower cost per part compared to standard milling inserts.
