Product Advantages
1. Superior Material & Coating Technology
Features GC1125 carbide substrate with exceptional hardness, wear resistance, and toughness, capable of withstanding high cutting temperatures and forces, minimizing insert chipping.
Innovative TiCN-Al2O3-TiN multilayer coating: outer TiN reduces friction, middle Al2O3 ensures high-temperature stability, inner TiCN enhances coating adhesion, extending tool life by 30%-50% compared to standard coated inserts.
Smooth coating surface enables efficient chip evacuation, reducing built-up edge (BUE) and ensuring superior workpiece surface finish.
2. Precision Geometry Design
Triangular shape with 3 cutting edges maximizes insert utilization and reduces per-part processing costs.
0.02 mm small corner radius is ideal for high-precision profiling and thin-walled component machining, preventing workpiece surface scratches.
Optimized rake angle and edge preparation minimize cutting forces and vibration, enhancing machining stability—perfect for high-precision processing of critical components.
3. Versatility & High Efficiency
Compatible with machining of carbon steel, alloy steel, stainless steel, cast iron, and other materials, meeting complex processing needs across multiple industries.
Suitable for finishing, semi-finishing, and profiling operations, compatible with turning centers, CNC lathes, and other machining equipment.
Compatible with high cutting speeds and feeds, improving production efficiency while maintaining processing quality, reducing unit time costs.
4. Quality Assurance
Complies with ISO standards and 's strict quality control system—each insert undergoes precision inspection to ensure dimensional accuracy and performance consistency.
Backed by 's century-old technical expertise and global service network, providing professional technical consultation and application solutions.
Application Scenarios
Automotive Manufacturing: Turning of precision components such as engine crankshafts, camshafts, and transmission gears.
Aerospace: Semi-finishing and finishing of aluminum alloy and titanium alloy structural parts.
General Engineering: Batch processing of gears, shafts, and sleeves.
Mold Making: Profiling of mold cavities and cores.
Medical Devices: High-precision cutting of stainless steel and titanium alloy medical components.
Installation & Usage Recommendations
Ensure the tool holder is compatible with the insert (recommended CoroTurn 107/200 series holders). Clean the contact surfaces of the holder and insert during installation to avoid positioning errors caused by impurities.
Recommended cutting parameters: Cutting speed (vc) = 100-300 m/min, Feed rate (f) = 0.05-0.2 mm/rev, Depth of cut (ap) = 0.1-2 mm (adjust based on workpiece material and machine performance).
Regularly inspect the cutting edge wear. Rotate or replace the insert when wear reaches 0.2-0.3 mm to maintain processing quality.
Use cutting fluid for machining sticky materials (e.g., stainless steel) to improve chip evacuation and extend tool life.
Packaging & After-Sales
Packaging: 10 inserts/box, moisture-proof and anti-static packaging to ensure product integrity during transportation.
Warranty: 12-month warranty under normal usage conditions. Return or exchange is available with purchase proof for quality issues.
Technical Support: Professional services including cutting parameter optimization and processing solution customization. A global rapid response team is available to resolve usage-related issues.
