Product Overview

The Kyocera CPMH080208HQ CA515 TAB01361 is a premium-grade indexable carbide insert engineered for high-precision finishing operations on CNC turning centers. Manufactured in Japan to stringent ISO 9001 quality standards, this insert combines an optimized 80° rhombic geometry with a multi-layer CVD coating to deliver exceptional surface finish, dimensional accuracy, and extended tool life across demanding production environments.

With an inscribed circle (IC) of 7.94 mm (0.313"), thickness 2.38 mm, and a 0.8 mm nose radius, the CPMH080208HQ is designed for high-precision finishing of steel and alloy steel workpieces. The CA515 grade substrate provides the ideal balance of hardness and toughness, ensuring reliable performance in both continuous and light-intermittent cutting conditions.

Grade Details — CA515 Key Characteristics

The CA515 grade is a Hard P30-P40 Carbide Substrate with a CVD Multi-Layer (TiCN + Al₂O₃ + TiN) multi-layer coating. This combination delivers:

Superior Crater Wear Resistance: The Al₂O₃ middle layer acts as a thermal barrier, protecting the substrate from high-temperature diffusion at cutting speeds up to 300 m/min.
Enhanced Flank Wear Resistance: The TiCN base layer provides excellent adhesion to the carbide, while the gold TiN top layer offers low friction and easy wear detection.
Optimized Edge Stability: Balanced substrate hardness (HRA 91.5) and TRS (≥2,200 MPa) prevent chipping in light-intermittent cuts.
Broad Application Range: Suitable for continuous to lightly interrupted cutting of carbon steel, alloy steel, and cast steel.

Grade Comparison Matrix

Property	CA515	CA510	CA520	CA530
Coating Type	TiCN + Al₂O₃ + TiN	TiCN + Al₂O₃	TiCN + Al₂O₃ + TiN	TiAlN (PVD)
Substrate Toughness	★★★★☆ High	★★★☆☆ Moderate	★★★★★ Very High	★★★★☆ High
Wear Resistance	★★★★★ Excellent	★★★★☆ Good	★★★★☆ Good	★★★★★ Excellent
Cutting Speed (Steel)	150–300 m/min	180–350 m/min	120–250 m/min	200–400 m/min
Best For	General steel turning	High-speed finishing	Heavy roughing	High-speed dry cutting
Intermittent Cutting	Light–Moderate	Continuous only	Moderate–Heavy	Light only

CA515 offers superior crater wear resistance vs CA510, with better edge stability than CA520. Ideal for general steel machining where reliability is paramount.

Recommended Applications & Workpiece Materials

The CPMH080208HQ CA515 is optimized for the following materials and operations:

Material Group	ISO Code	Compatibility	Typical Application
Carbon Steel	P1.1–P1.5	★★★★★ Excellent	Shafts, gears, structural components
Alloy Steel	P2.1–P2.5	★★★★★ Excellent	Crankshafts, connecting rods, axles
Tool Steel	P3.0–P3.2	★★★★☆ Good	Dies, molds, cutting tools (pre-hardened)
Stainless Steel	M1.0–M2.0	★★★☆☆ Moderate	Valves, fittings, food-processing equipment
Cast Steel	P4.0–P4.2	★★★☆☆ Moderate	Pump housings, valve bodies, automotive castings
Hardened Steel (≤45 HRC)	H1.0–H2.0	★★★★☆ Good	Transmission gears, bearing races, camshafts

Application Map by Operation

Operation Type	Suitability	Recommended Parameters
External Turning	★★★★★ Excellent	v_c = 200–350 m/min \| f = 0.05–0.2 mm/rev \| a_p = 0.1–1.5 mm
Internal Turning (Boring)	★★★★☆ Good	Reduce v_c by 15–20% vs external; use rigid setup
Face Turning	★★★★★ Excellent	Lead angle 45–95°; a_p ≤ 0.8 mm for finishing
Profiling / Contouring	★★★★☆ Good	Small nose radius enables tight radii; reduce feed for accuracy
Copy Turning	★★★★☆ Good	Use reduced feed (0.10–0.20 mm/rev) for complex geometries

Recommended Cutting Conditions

Parameters below are starting recommendations for carbon and alloy steel using the CPMH080208HQ CA515. Adjust based on machine rigidity, coolant delivery, and workpiece condition:

Operation	Cutting Speed v_c	Feed Rate f	Depth of Cut a_p	Coolant
Roughing	200–230 m/min	0.15–0.20 mm/rev	0.8–1.5 mm	Flood (8–10% emulsion)
Medium Cutting	230–320 m/min	0.10–0.20 mm/rev	0.4–0.8 mm	Flood or high-pressure
Finishing	320–350 m/min	0.05–0.13 mm/rev	0.1–0.4 mm	Flood or mist
High-Speed Finishing	350–400 m/min*	0.05–0.05 mm/rev	0.05–0.3 mm	High-pressure (70+ bar)

*High-speed parameters require stable machine conditions and excellent coolant delivery. Reduce by 20% for alloy steels above 800 MPa tensile strength.

Operating Guidelines

Toolholder Selection: Use a rigid toolholder with minimum overhang. For negative inserts, ensure the toolholder provides adequate negative rake (-5° to -7°). For positive inserts, select a toolholder with 0° to 5° inclination.
Cutting Edge Preparation: The CPMH080208HQ features a polished surface to minimize burr formation and improve edge stability.
Coolant Recommendations: Water-soluble cutting fluid (8–10% concentration) is recommended for steel machining. Ensure coolant is directed at the cutting zone. For high-speed finishing, high-pressure coolant (≥70 bar) significantly improves chip evacuation and surface finish.
Chip Management: Superior chip curling for fine finishes. Monitor chip shape—ideal chips should be short C- or 6-shaped segments. Long, stringy chips indicate insufficient feed or worn insert.
Edge Life Monitoring: The gold TiN top layer on CA515 provides visual wear indication. When the gold color disappears and silver substrate becomes visible, replace the insert to maintain dimensional accuracy.
Workpiece Preparation: Minimize scale, rust, and casting skin. For castings or forged parts, reduce cutting speed by 25–30% during the first pass to protect the cutting edge from hard surfaces.

Toolholder Compatibility

The CPMH080208HQ is compatible with the following ISO-standard toolholder families:

Toolholder Family	Approach Angle	Best For	Insert Clamping
PCLNR / PCLNL	95°	External turning, general purpose	Lever lock (L) or top clamp (R)
PCKNR / PCKNL	75°	Heavy roughing, high depth of cut	Lever lock
SCLCR / SCLCL	91°	Internal boring, copy turning	Screw clamp or lever lock

Compatibility Note: PCLNR / PCLNL (95° toolholder), PCKNR / PCKNL (75° toolholder), SCLCR / SCLCL (91° toolholder) Ensure the toolholder seat matches the insert shape (80° Rhombic) and thickness (2.38 mm). Use a torque wrench set to 3.5–4.5 N·m for screw-clamp holders to avoid insert fracture.
