Product Overview
The CPMH080204 is a premium CVD-coated carbide indexable insert from Kyocera, engineered for precision CNC turning operations. Featuring the advanced CA125P grade with a multi-layer TiCN/Al₂O₃/TiN coating, this insert delivers exceptional wear resistance, fracture toughness, and thermal stability in steel machining environments. The 80° rhombic (diamond) geometry with a 0.4 mm nose radius ensures optimal edge strength and surface finish quality, making it ideal for general purpose turning, copying applications.
ISO Designation Breakdown
Complete decoder for the CPMH080204 ISO 1832 designation:
| Position | Code | Meaning |
|---|---|---|
| 1 – Shape | C | 80° Rhombic (Diamond) |
| 2 – Clearance | P | 11° (Positive) |
| 3 – Tolerance | M | ±0.13mm (Standard) |
| 4 – Type | H | With cylindrical hole |
| 5 – Length | 08 | 9.525 mm cutting edge |
| 6 – Thickness | 02 | 2.38 mm insert thickness |
| 7 – Radius | 04 | 0.4 mm nose radius |
| 8 – Chipbreaker | Standard – universal geometry for general turning |
Engineering Dimensions & Geometry
Verified dimensional data per ISO 1832:2012 standard:
| Parameter | Value | Notes |
|---|---|---|
| Inscribed Circle (IC) | 9.525 mm | Nominal cutting edge length per ISO 1832 |
| Insert Thickness (S) | 2.38 mm | ±0.13 mm tolerance class M |
| Nose Radius (rε) | 0.4 mm | Directly affects surface roughness Rz |
| Corner Angle | 80° | Determines tool engagement & stability |
| Relief Angle | Positive | Reduces flank rubbing, lowers heat |
| Hole Diameter | 4.4 mm (standard clamp) | Compatible with lever-lock toolholders |
Surface roughness estimate: Rz ≈ f² / (8 × rε) × 1000. For f = 0.1 mm/rev and rε = 0.4 mm, theoretical Rz ≈ 3.13 μm.
Grade Details – Key Grade Characteristics
- Substrate: Newly developed high-temperature-strength carbide with enhanced plastic-deformation resistance
- Coating Stack: Proprietary TiCN base layer + ultra-uniform Al₂O₃ (alumina) crystal layer + gold TiN surface layer
- Rake Face: Black finish – highly uniform alumina reduces crater wear and suppresses chip welding
- Flank Face: Gold finish – hard surface layer improves abrasion resistance; color contrast aids edge-wear inspection
- ISO Application Group: P15–P35 (steel machining, continuous to interrupted)
- Hardness: ~1,600 HV (coating surface); substrate optimized for 800–1,000°C cutting zone
Grade Comparison Matrix
How CA125P compares within the Kyocera steel-turning portfolio:
| Grade | Coating | Application | Machining Type |
|---|---|---|---|
| CA125P | TiCN + Al₂O₃ + TiN (CVD) | Steel, alloy steel | Continuous → heavy interrupted |
| CA115P | TiCN + Al₂O₃ + TiN (CVD) | Steel, high-speed | Continuous → light interrupted |
| CA525 | TiCN + Al₂O₃ + TiN | Steel, stainless | General purpose |
| CA6515 | TiCN + Al₂O₃ + TiN | Steel, heavy duty | Heavy interrupted |
Chipbreaker Profile
– Standard – universal geometry for general turning
- Geometry: Standard rake with neutral chip groove
- Chip Formation: Standard C-chip formation, reliable control
- Cutting Force: Low-to-moderate radial & axial forces; reduced chatter risk on slender workpieces
- Coolant Compatibility: Optimized for wet cutting and MQL; flood coolant recommended for deep cuts
Recommended Applications & Workpiece Materials
- Primary Materials: Carbon steel, alloy steel, mild steel
- Hardness Range: 80–350 HB (ideal 150–280 HB)
- Typical Components: Shafts, gears, bearing races, hydraulic cylinders, valves, pump housings
- Industries: Automotive, aerospace, general machinery, energy, mold & die
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| External Turning | ★★★★★ Excellent | Primary application; stable at high speeds |
| Internal Boring | ★★★★☆ Very Good | Use with minimum 11.525 mm bore diameter |
| Facing | ★★★★☆ Very Good | Ensure center clearance at small diameters |
| Profiling / Copying | ★★★☆☆ Good | 80° corner provides strong edge entry |
| Interrupted Cutting | ★★★☆☆ Good | Reduce Vc 20% for heavy interrupted cuts |
Recommended Cutting Conditions
Starting parameters for CA125P with CPMH080204 in wet machining of carbon/alloy steel:
| Operation | Vc (m/min) | f (mm/rev) | ap (mm) | Condition |
|---|---|---|---|---|
| Finishing | 220 | 0.08 | 0.3 | Wet / MQL |
| Semi-Finishing | 140 | 0.12 | 0.6 | Wet |
| Medium | 140 | 0.2 mm/rev | 1.5 mm | Wet |
Adjustments: Reduce Vc by 15% for dry cutting; increase feed by 10% for cast iron; reduce both by 20% for stainless steel.
Operating Guidelines
- Run-in Period: For first 5 min, reduce Vc by 25% to stabilize coating and edge micro-geometry
- Tool Life Indicator: Monitor flank wear (VB) ≤ 0.3 mm; replace insert when gold flank shows uniform wear land
- Chip Inspection: Blue or purple chip color indicates excessive heat – reduce Vc or increase coolant flow
- Clamping Torque: Lever-lock toolholders: 3.5–4.5 N·m; do not overtighten to avoid insert fracture
- Storage: Keep inserts in original blister pack; avoid direct sunlight and humidity >60% RH
Toolholder Compatibility
PCLN, PCLNL, MCLN, MCLNR, CCLN (80° rhombic). Use lever-lock or top-clamp styles. Recommended shim: 80° diamond shim (e.g., ST-1303).
| Holder Style | Approach Angle | Use Case |
|---|---|---|
| PCLN / PCLNL | 95° | External turning, facing |
| MCLN / MCLNR | 95° | Medium roughing, heavy duty |
| DDJN / DDJNL | 93° | Copying, profiling, undercuts |
