Turning inserts: carbide tools and lathe tool factory
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%

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.
