R390CNC Turning Cutting Tools Inserts

      About the product

 R390 indexable inserts are designed for efficient milling operations, featuring a robust geometry that allows for high feed rates and large cutting depths, up to 9mm. They provide four cutting edges per insert, enhancing economy and versatility compared to traditional options. The sharp cutting edge minimizes cutting force, making them suitable for a variety of materials, including cast iron, steel, and stainless steel. Their optimized design ensures improved surface finish and wear resistance, making them ideal for both finishing and roughing applications.

Material & Coating Technology

• Base Material: Carbide blades Manufactured from high-purity, high-hardness raw carbide with a fine micrograin structure (grain size 0.8–1.2μm). The carbide is bonded with 7–9% cobalt, balancing exceptional hardness (91–93 HRA) and structural toughness to resist chipping during high-load machining.

• Cermet Composition: Integrates next-generation coated cermets—ceramic-metal composites (titanium carbide/nitride reinforced with metallic binders)—engineered for superior wear resistance in high-speed cutting of ferrous materials.

• 
  

• PVD Coating: Equipped with an advanced Physical Vapor Deposition (PVD) coating (e.g., TiAlN or AlTiN) with a thickness of 3–5μm. This coating enhances oxidation resistance up to 800°C, reduces friction between the insert and workpiece, and extends tool life by 25–30% compared to uncoated alternatives.

Key Features

• Multiple Material Compatibility: CNC turning cutting tools Designed to machine a broad range of materials, including hot/cold forged steels, sintered ferroalloys, carbon steel, alloy steel, and other ferrous metals, eliminating the need for frequent tool changes.

• Enhanced Machining Performance: Delivers superior results in finishing and continuous machining operations, with optimized chip control and stable cutting behavior even in high-speed applications.

• Excellent Wear & Pitting Resistance: The combination of high-hardness carbide, cermet reinforcement, and PVD coating minimizes abrasive wear and pitting, ensuring prolonged edge integrity in demanding conditions.

• Optimized Cutting Edge: Precision-honed cutting edges with a micro-radius (0.01–0.03mm) reduce cutting forces, minimize burr formation, and improve surface finish quality (Ra ≤ 1.0μm in finishing operations).

• High-Speed Stability: The advanced coating and material formulation enable reliable performance at cutting speeds up to 200–300 m/min for steels, supporting high-productivity machining.

Applications

• Automotive Manufacturing: Finishing and semi-finishing of hot/cold forged steel components such as crankshafts, gear blanks, and axle parts.

• Heavy Machinery: Machining sintered ferroalloy parts and high-strength steel components (e.g., hydraulic cylinders, industrial gears).

• Tool & Die Making: Precision turning of mold bases and die blocks from alloy steel, where surface finish and dimensional accuracy are critical.

• General Engineering: Continuous machining of carbon steel shafts, bushings, and structural components in batch production.

Compatible Machines

• CNC Lathes: Fanuc 0i-TF, Siemens Sinumerik 828D, Haas ST-series, and Mazak Quick Turn models, paired with standard external turning toolholders (e.g., MTJNR, SVJCR).

• Slant-Bed CNC Lathes: Doosan Puma and Okuma LB series, leveraging the machines’ high rigidity to maximize stability during high-speed cutting.

• Multi-Axis Turning Centers: DMG Mori NTX and Mazak Integrex series, supporting complex contour turning and interrupted cuts with consistent performance.

Lifespan & Performance Metrics

• Recommended Cutting Parameters:

• Forged Steels: Cutting speed 150–300 m/min; feed rate 0.1–0.3 mm/rev.

• Sintered Ferroalloys: Cutting speed 120–250 m/min; feed rate 0.08–0.2 mm/rev.

• Service Life: Under optimal conditions:

• 60–90 minutes of continuous finishing per cutting edge on forged steel.

• 45–70 minutes per edge on abrasive sintered ferroalloys.

• Total lifespan across all usable edges: 240–360 minutes, extended by the wear-resistant coating and base material.
