As a core manufacturer of cemented carbide tools, we, Lizhou, focus on innovation in the turning field to Carbide Insert Lathe Tools （Cemented carbide lathe inserts） 、 Cutting Carbide Inserts （Cutting cemented carbide inserts） 、 Carbide Cutter Inserts （Cemented carbide inserts） 、 Inserts for Turning （Turning inserts）, four major product matrices, providing global users with precisely matched metal processing solutions.
The advantages of our turning inserts ( Inserts for Turning ) are:
1. Ultra-hard matrix, challenging extreme processing
Using nanocrystalline ( 0.5μm grade) cemented carbide substrate, the hardness reaches 93.5HRA ，improved anti-crushing performance 60%：
The single-edge life of rough turning cast iron exceeds 120 minutes
The surface roughness of precision turning quenched and hardened steel ( HRC55 ) remains stable at Ra0.8μm
2. Intelligent coating, uncompromising high temperature
PVD+PCVD composite coating technology, 8μm gradient protective layer is achieved:
Anti-oxidation temperature exceeds 1100℃
The cutting speed when turning stainless steel can reach 350m/min
The occurrence rate of built-up edge in titanium alloy processing is reduced 75%
3. Geometric revolution, efficiency multiplier
• Double-sided 16 cutting edge design ：Utilization rate improvement 200% ，reducing the cost of single-piece processing
• 0.02mm Grade cutting edge blunting ：Eliminate microscopic chipping, size fluctuation when precision turning copper parts ≤5μm
• Adaptive chip breaker ：From continuous chips to C type chips are matched with one click, and the chip flow rate is improved 90%

Recommended high cost-effective turning inserts ( inserts for turning )
1. TNMG160404-PV\43 Triangular insert
Features ：Double-sided 6 cutting edge design, matched with TiAlN coating ( PV technology), high temperature resistance up to 800°C ，suitable for high-speed continuous cutting.
Applicable materials ：Semi-finishing to finishing of stainless steel, alloy steel, and cast iron.
Advantages ：0.4mm The tip radius can improve the surface roughness ( Ra≤1.6μm )，excellent economy.
2. SNMG120408-TM\HX Square cutter
Features ：Double-sided 8 Blade structure, using multi-layer composite coating ( TM technology), strong anti-chipping performance, specially designed for heavy-duty intermittent cutting.
Applicable materials ：Rough machining of forgings and castings, especially good at high-hardness alloy steel.
Advantages ：12mm The inscribed circle diameter takes into account both cutting depth and rigidity, and the feed rate can reach 0.5mm/rev。
Applicable materials and optimized processing parameters
No matter what you are processing Stainless steel 、 Alloy steel 、 Cast iron or High temperature alloy ，choose the appropriate Carbide cutter inserts ( carbide cutter inserts ) and adjusting the parameters is crucial:
Stainless steel ：
Recommended cutter ： TNMG160404-PV\43 (Fine machining) / CNMG120408-MP (Rough machining).
Parameter suggestions ：Cutting speed 120-180m/min ，Feed rate 0.1-0.3mm/rev ，Use high-pressure coolant to reduce built-up edge.
Cast iron ：
Recommended cutter ： SNMG120408-TM\HX (Rough machining) / DNMG150608-KM (Fine machining).
Parameter suggestions ：Cutting speed 80-150m/min ，Large cutting depth ( 3-5mm ) prioritize efficiency, dry cutting or minimal lubrication.
High temperature alloy ：
Recommended cutter ：Special coated blades (such as AlCrN coating), tip radius ≤0.2mm 。
Parameter notes ：Reduce cutting speed to 50-80m/min ，Small cutting depth ( 0.1-0.3mm ) avoid thermal stress concentration.
