TNMG160404 Turning Inserts

GC Sharp Groove Type: This groove type employs a precision edge grinding process, which strictly controls the radius of the cutting edge to a minimum of 5μm or less, significantly reducing cutting forces. Its sharp cutting edge excels in machining low-hardness non-ferrous metals such as 6061-T6 aluminum alloy and C36000 copper alloy, effectively reducing elastic recovery and plastic deformation on the workpiece surface. It is ideal for high-speed, lightweight cutting of thin-walled and easily deformed parts, effectively preventing workpiece vibration or dimensional deviations caused by excessive cutting forces.

GM universal slot: Optimized based on fluid mechanics principles, this chip breaker slot ensures stable and controllable chip breaking across a wide range of cutting parameters. This makes the GM slot an ideal choice for machining common carbon steels like Q235 and alloy structural steels. Whether for rough machining to remove significant allowances or finish machining to ensure surface quality, it ensures continuous and stable cutting processes, with reliable chip-breaking performance that minimizes the risk of long chips entangling the tool or workpiece.

The MA multi-purpose groove type: This groove type has been optimized to enhance the strength and heat dissipation of the cutting edge, while maintaining versatility. It is suitable for continuous and intermittent cutting of medium-hard materials, such as alloy steels in a quenched and tempered state like 42CrMo and cast iron. At medium feed rates and cutting speeds, it provides excellent chip control, high metal removal rates, and extended tool life.

FS Strong Type Groove: Designed for heavy-duty cutting conditions, this groove significantly enhances the support structure of the cutting edge and increases the strength of the cutting edge. It is specifically developed for machining hard-to-machine materials such as high-hardness quenched and tempered die steels. It can withstand cutting stresses of over 1500MPa at high cutting depths and feed rates, effectively resisting impact loads. It is a reliable choice for roughing or semi-finishing hard materials.

TM slot type (profile/machining type): This slot type typically features a smaller tool tip radius and optimized chip evacuation channels, focusing on high-precision machining and profile processing with low surface roughness. It is suitable for the precision machining of surfaces with extremely high dimensional accuracy and surface quality, such as stainless steel alloy steel. It can operate stably at very small cutting depths and low feed rates.

The base material of TNMG160404 Turning Insert is ultra-fine-grained hard alloy, with grain sizes strictly controlled to be below 0.6μm. This material achieves an excellent balance of high strength (bending strength> 1800MPa) and high toughness (fracture toughness> 8MPa·m^0.5). The surface is coated with a multi-layer composite TiAlN coating using advanced PVD (Physical Vapor Deposition) technology. The coating of TNMG160404 Turning Insert has a hardness exceeding 2500HV and an oxidation resistance temperature over 1000°C, significantly reducing the temperature in the cutting zone and decreasing the friction coefficient between the tool and the workpiece, thus greatly extending the tool's service life.

After daily use, immediately clean the insert surface and the chip removal grooves with a dedicated cleaning agent and a soft-bristled brush to remove chips, residual cutting fluid, and abrasive particles. This prevents the buildup of dry residues and protects the TNMG160404 insert from corrosion. When the back face wear reaches 0.3mm or the crescent depression wear depth reaches 0.1mm, it is recommended to replace the insert promptly. Selecting the appropriate cutting fluid is crucial; choose based on the workpiece material and processing method, keep it clean, and replace it regularly to ensure effective lubrication and cooling. Be cautious of accidental impacts or drops to prevent the insert edge from chipping.

The TNMG160404 Turning Insert is primarily used in various CNC lathes and turning centers to perform operations such as external cylindrical turning, end face turning, slotting, and profile machining. Compared to milling inserts of the same shape, the TNMG160404 turning insert is designed to withstand radial or axial forces in a single direction. Its cutting edge geometry and slot design are optimized for efficient and stable material removal from the surface of rotating bodies. Compared to other brands of turning inserts of the same shape, the OYT SR2025 series inserts, with their refined multi-slot strategy, can more accurately meet specific material and process requirements. The combination of ultra-fine grain matrix and high-performance PVD coating ensures reliability and cost-effectiveness under harsh conditions.
