1. Product Overview

The Kyocera CNMG120404KG CA320 TME01015 is a precision-engineered CVD coated carbide indexable turning insert from the CA3 Series. Designed specifically for cast iron machining, this insert combines a specialized carbide substrate with a multi-layer TiCN + Al₂O₃ + TiN coating to deliver exceptional wear resistance, thermal stability, and fracture toughness in demanding applications.

The General Cast Iron chipbreaker (KG) geometry ensures versatile k-series chipbreaker for a wide range of cast iron applications from continuous to interrupted machining. With a 0.4 mm corner radius and 4.76 mm thickness, this insert is optimized for general cast iron turning, continuous to light interrupted, long workpieces.

4. Grade Details – Key Grade Characteristics

CA320 is a premium CVD coated carbide grade from Kyocera's CA3 Series, engineered specifically for cast iron machining. The rose-gold colored coating consists of:

Micro TiCN Base Layer: Provides exceptional hardness and wear resistance through micro-crystal structure.
Al₂O₃ Intermediate Layer: Thick alumina coating offers superior thermal barrier properties and crater wear resistance at high cutting temperatures.
TiN Top Layer: Gold-colored surface layer improves chip flow and reduces built-up edge formation.

The specialized carbide substrate is optimized for cast iron applications, providing the ideal balance between hardness and toughness required for interrupted cuts in nodular cast iron.

Property	Value	Significance
Coating Hardness	1,570 HV	Superior abrasion resistance
Transverse Rupture Strength	2,780 MPa	High fracture resistance under impact
Fracture Toughness	15.4 MPa·m¹/²	Reliable performance in interrupted cuts
Coating Thickness	15.0 μm	Extended tool life in continuous cuts
Coating Adhesion	+20% vs conventional	Prevents chipping and delamination

5. Grade Comparison Matrix

Select the optimal CA3 Series grade for your cast iron application:

Grade	Coating	Hardness (HV)	Primary Application	Machining Type
CA310	TiCN + Al₂O₃ + TiN	1,570	Gray Cast Iron	Continuous to Light Interrupted
CA315	TiCN + Al₂O₃ + TiN	1,570	Nodular Cast Iron	Continuous to Interrupted
CA320	TiCN + Al₂O₃ + TiN	1,570	Nodular Cast Iron	Heavy Interruption / High Speed

9. Recommended Cutting Conditions

Values below are starting recommendations. Adjust based on machine rigidity, workpiece condition, and desired tool life.

Workpiece Material	Cutting Speed Vc (m/min)	Feed f (mm/rev)	Depth of Cut ap (mm)	Coolant
Gray Cast Iron (FC200)	180-250	0.10 – 0.45	0.5 – 4.0	Wet / Dry
Nodular Cast Iron (FCD500)	120-180	0.10 – 0.45	0.5 – 4.0	Wet / Dry
Malleable Cast Iron	150-200	0.10 – 0.45	0.5 – 4.0	Wet / Dry
Interrupted Cut (FCD700)	100-150	0.15 – 0.45	1.0 – 4.0	Wet (high pressure)

Note: For scale-covered or sand-cast surfaces, reduce Vc by 20–30%. For stable continuous cuts, increase Vc by 15–20%.

10. Operating Guidelines

Toolholder Selection: Use 80° diamond toolholders with IC 12.7 mm pocket. Ensure pocket cleanliness and proper insert seating.
Cutting Speed (Vc): Start at the lower end of the recommended range and increase based on tool life and surface finish requirements.
Feed Rate (f): For roughing, use higher feeds with PH/KH chipbreakers. For finishing, reduce feed with WQ/ZS geometries.
Depth of Cut (ap): Maintain ap ≥ 2× corner radius for optimal edge engagement and chip control.
Coolant: Wet cutting is recommended for cast iron to control dust and improve surface finish. Minimum Quantity Lubrication (MQL) acceptable for finishing.
Insert Change: Monitor flank wear (VB). Replace when VB = 0.3 mm for roughing or 0.15 mm for finishing.
Security: Ensure proper clamping torque on toolholder screw (recommended 3.5–4.5 N·m).
