Kyocera PR18 Series PVD Milling Grades
The Kyocera PR18 Series represents a next-generation PVD coating technology engineered for milling applications. Developed by Kyocera, this coating lineup utilizes advanced MEGACOAT NANO EX double lamination technology to deliver exceptional wear resistance, high-temperature hardness, and extended insert life across demanding milling conditions.
Key Innovations in the Kyocera PR18 Series
Next-generation milling performance relies on multi-layer coating structures that absorb thermal stress and inhibit crack propagation:
- MEGACOAT NANO EX Coating Technology: A specialized PVD coating that improves upon conventional nano-laminated structures with superior abrasion resistance, high hardness, and oxidation resistance.
- Double Lamination Structure: Combines two unique nano layers (Special Nano Layer x Multilayer Lamination) to optimize internal stress and suppress crack growth during heavy cutting.
- AlCr-Based Nano Layer: Provides exceptional surface hardness and abrasion resistance to suppress flank and top face wear.
- AlTi-Based Nano Layer: Delivers high heat resistance and toughness, protecting the carbide substrate under high-temperature milling speeds.
- Broad Milling Compatibility: Expandable across 16 different milling cutter series to address varied machining environments.
Grade Options & Application Coverage
The PR18 product lineup provides three specialized grades tailored to specific workpiece materials: PR1825 optimized for wear-resistant steel milling, PR1835 engineered for stability-oriented steel and stainless steel milling, and PR1810 designed for high-durability cast iron machining.
Technical Specifications
| Grade Name | Primary Target Workpiece Material | Coating Technology | Primary Performance Advantage |
|---|---|---|---|
| PR1825 | Steel (Carbon & Alloy Steel) | MEGACOAT NANO EX (Double Lamination PVD) | Wear resistance oriented; excellent for continuous steel milling |
| PR1835 | Steel & Stainless Steel | MEGACOAT NANO EX (Double Lamination PVD) | Stability oriented; high fracture resistance for interrupted cutting |
| PR1810 | Cast Iron (Ductile & Gray Cast Iron) | MEGACOAT NANO EX (Double Lamination PVD) | High hardness and thermal stability for heavy cast iron milling |
