TNMG 1604 Carbide Ceramic Inserts

About the product

The TNMG1604 Ceramic cutting inserts  ceramic insert is a triangular, negative rake angle insert designed for efficient cutting. With an internal inscribed circle (IC) of 0.5 inches (12.7mm), a thickness of 0.188 inches (3/16 inches), and a nose radius of 0.0625 inches (1/16 inches), this insert is suitable for general-purpose work. The 60° included angle of the TNMG432 insert makes it ideal for versatile turning operations, while its negative rake angle design provides a durable cutting edge that is ideal for hard materials and intermittent cutting. In addition, the TNMG432 insert is often coated with materials such as TiN, TiCN, AlTiN, etc. to extend tool life and improve wear resistance. This insert performs well in roughing, semi-finishing, and finishing, and is particularly suitable for steel, cast iron, and some harder materials.

Material & Coating 

The TNMG1604 Best carbide inserts  is constructed from high-performance carbide ceramic, blending a tungsten carbide substrate with ceramic reinforcements (e.g., titanium carbide or aluminum oxide) and a cobalt binder (6–8% content). This composition delivers exceptional hardness (92–94 HRA) and wear resistance, critical for machining hard materials. Most variants feature advanced coatings: - **TiN (Titanium Nitride)**: Enhances surface hardness and reduces friction, ideal for general-purpose steel machining. - **TiCN (Titanium Carbonitride)**: Improves wear resistance in medium-load operations, suitable for cast iron. - **AlTiN (Aluminum Titanium Nitride)**: Provides high-temperature stability (up to 900°C) and oxidation resistance, optimizing performance in stainless steel and hard alloy machining.

Key Features & Geometry

• Triangular Design with 60° Included Angle: The 60° included angle offers versatility for multi-directional turning, enabling operations like facing, profiling, and shoulder turning with a single insert.

• Negative Rake Angle: The negative rake geometry strengthens the cutting edge, enhancing durability in intermittent cutting and reducing edge chipping when machining hard or abrasive materials (e.g., hardened steel, cast iron).

• Precise Dimensional Specifications:

• Internal Inscribed Circle (IC): 0.5 inches (12.7mm)

• Thickness: 0.188 inches (3/16 inches), ensuring rigidity under high cutting forces.

• Nose Radius: 0.0625 inches (1/16 inches), balancing surface finish quality (Ra ≤ 1.6μm in finishing) and edge strength.

• General-Purpose Versatility: Designed to perform across roughing, semi-finishing, and finishing operations without compromising efficiency.

Applications

• Steel Machining: Carbon steel, alloy steel, and high-strength steel components (e.g., automotive shafts, industrial bolts).

• Cast Iron Processing: Gray cast iron and ductile iron parts (e.g., engine blocks, pump housings) where abrasive wear resistance is critical.

• Hard Materials: Hardened steel (up to 45 HRC) and heat-resistant alloys, suitable for tool and die making.

• Intermittent Cutting: Reliable performance in applications with varying loads, such as machining parts with slots or keyways.

  
  

Compatible Machines

• CNC Lathes: Fanuc-controlled lathes (e.g., Fanuc 0i-TF), Haas ST-series, and Mazak Quick Turn models, paired with standard toolholders (e.g., MTJNR, SVJCR) for precise tool alignment.

• Manual Lathes: Traditional lathes with tool post setups (e.g., South Bend, Clausing) for general-purpose turning tasks.

• Multi-Axis Turning Centers: Machines combining turning and milling capabilities (e.g., DMG Mori NTX series), leveraging the insert’s versatility for complex part production.

Lifespan & Performance

• Cutting Speed Range: 120–250 m/min (steel), 80–180 m/min (cast iron), 100–200 m/min (stainless steel).

• Feed Rate: 0.1–0.3 mm/rev, balancing material removal efficiency and surface finish.

• Service Life: Each cutting edge lasts 45–90 minutes of continuous machining on steel; 30–60 minutes on cast iron due to higher abrasiveness. The negative rake design and coating extend total lifespan by 20–30% compared to positive rake inserts in hard material applications.

Advantages

• Durability in Hard Machining: Negative rake angle and robust carbide ceramic construction resist edge wear and chipping in demanding conditions.

• Cost-Effective Versatility: Eliminates the need for multiple insert types by covering roughing to finishing, reducing tool inventory costs.

• Consistent Surface Finish: The 0.0625-inch nose radius ensures smooth finishes, meeting precision requirements in automotive and industrial components.
