Grade Details - Key Grade Characteristics
The CA515 grade represents Kyocera's advanced PVD-coated carbide technology, specifically formulated for high-performance machining of ferrous materials:
- Substrate: Ultra-fine grain tungsten carbide (WC-Co) with 10% cobalt binder for optimal toughness
- Coating: Multi-layer PVD TiAlN (Titanium Aluminum Nitride) providing exceptional oxidation resistance up to 900°C
- Hardness: 92.5 HRA (1600 HV30) ensuring superior wear resistance
- Transverse Rupture Strength: >3,500 N/mm² for reliable performance under intermittent cuts
- Thermal Conductivity: Optimized heat dissipation reducing thermal cracking risk
- Surface Finish: Mirror-polished rake face minimizes built-up edge (BUE) and improves chip flow
Grade Comparison Matrix
Compare CA515 with adjacent grades in the Kyocera portfolio:
| Grade | Substrate | Coating | Best For |
|---|---|---|---|
| CA515 | Ultra-Fine Carbide | PVD TiAlN | Steel, Stainless Steel, Cast Iron |
| CA525 | Fine Carbide | PVD Multi-Layer | General Steel Machining |
| CA535 | Medium Carbide | CVD Al2O3+TiCN | Heavy-Duty Cast Iron |
Chipbreaker Profile
WF - Wear-Resistant, Fine Finishing Chipbreaker
The specialized chipbreaker geometry on the DNMX150412WF ensures precise chip formation and evacuation across a wide feed range. The optimized groove depth and width promote tightly curled chips that break reliably, preventing chip nesting and protecting both the insert and workpiece surface.
- Chip Curl Radius: 2.5–4.0 mm (optimized for wear-resistant finishing)
- Chipbreaker Width: 0.8–1.2 mm (varies by insert thickness)
- Rake Angle: Positive 8°–12° for reduced cutting forces
- Land Width: 0.15–0.25 mm for edge strength
Recommended Applications & Workpiece Materials
The DNMX150412WF CA515 is ideally suited for the following materials and operations:
- Carbon Steels: C35, C45, C60 (DIN); 1045, 1060 (AISI) — Excellent chip control and finish
- Alloy Steels: 42CrMo4, 34CrNiMo6, 4140, 4340 — High wear resistance at elevated speeds
- Stainless Steels: 304, 316, 420, 17-4PH — Reduced work-hardening and built-up edge
- Cast Irons: GG25, GG30, GGG40 (DIN); Class 30, 40 (ASTM) — Stable performance in interrupted cuts
- Tool Steels: H13, D2, O1 (pre-hardened to 45 HRC max) — Reliable under moderate loads
Application Map by Operation
Suitability ratings for common turning operations:
| Operation | Suitability | Recommended Feed | Recommended Speed |
|---|---|---|---|
| External Turning | ★★★★★ Excellent | 0.1–0.4 mm/rev | 150–300 m/min |
| Internal Boring | ★★★★☆ Very Good | 0.08–0.3 mm/rev | 120–250 m/min |
| Face Turning | ★★★★★ Excellent | 0.12–0.5 mm/rev | 160–320 m/min |
| Profiling | ★★★★☆ Very Good | 0.05–0.2 mm/rev | 140–280 m/min |
Recommended Cutting Conditions
Starting parameters for CA515 grade. Adjust based on machine rigidity and workpiece condition:
| Workpiece Material | Hardness (HB) | Cutting Speed (m/min) | Feed (mm/rev) | Depth of Cut (mm) |
|---|---|---|---|---|
| Carbon Steel | 125–225 | 180–280 | 0.1–0.35 | 0.5–3.0 |
| Alloy Steel | 180–280 | 150–240 | 0.1–0.3 | 0.5–2.5 |
| Stainless Steel | 150–250 | 120–200 | 0.08–0.25 | 0.5–2.0 |
| Cast Iron | 180–260 | 140–220 | 0.12–0.4 | 0.8–3.5 |
Operating Guidelines
- Tool Overhang: Minimize overhang to reduce vibration; use damped toolholders for L/D > 4
- Coolant: High-pressure coolant (70+ bar) recommended for stainless steel; flood coolant acceptable for cast iron
- Entry/Exit: Use ramp entry or rounded corner paths to avoid impact loading on insert nose
- Depth of Cut: Maintain DOC > nose radius (RE) × 2 to prevent rubbing and premature wear
- Feed Rate: For wear-resistant finishing, start at lower feed and increase gradually to optimize surface finish
- Tool Life Monitoring: Inspect flank wear (VB) every 15 minutes; replace when VB = 0.3 mm
- Edge Preparation: Do not re-sharpen; index to fresh edge or replace insert
