Kyocera CNMG190608 CA315 TMD01070 Negative Turning Insert - Heavy-Dut

Product Overview

The Kyocera CNMG190608 CA315 (TMD01070) is a premium rhombic 80° negative turning insert engineered for heavy-duty roughing operations on CNC turning centers. Manufactured in Japan with Kyocera's proprietary CVD multi-layer coating technology, this insert delivers exceptional wear resistance, thermal stability, and predictable tool life in continuous and light-interrupted steel machining applications.

Designed for the P15-P35 application range, the CA315 grade combines a tough carbide substrate with TiCN-Al₂O₃-TiN coating layers to achieve the optimal balance between cutting speed, feed rate, and depth of cut. The Rhombic 80° geometry ensures stable cutting forces and excellent chip evacuation, reducing machine downtime and improving surface finish quality.

Engineering Dimensions & Geometry

All dimensions conform to ISO 1832 and ANSI B212.4 standards for universal compatibility:

Grade Details — Key Grade Characteristics

CA315 is a CVD-coated grade positioned in the P15-P35 range for steel machining. Key characteristics include:

• Substrate: Tough WC-Co carbide with optimized cobalt content for edge strength
• Coating Structure: TiCN (base) + Al₂O₃ (middle) + TiN (top) — total thickness ~12 μm
• Coating Benefits: TiCN provides adhesion; Al₂O₃ provides thermal insulation; TiN provides wear recognition and low friction
• Color: Gold-yellow top layer for easy wear identification
• Cutting Speed Range: 120–350 m/min depending on operation and material
• Max Operating Temp: 900°C (continuous), 1050°C (interrupted)

Chipbreaker Profile

The CNMG190608 features a precision-ground chipbreaker geometry optimized for heavy-duty roughing:

• Chipbreaker Type: Standard groove with positive rake land
• Chip Control: Effective for feeds 0.10–0.60 mm/rev in steel
• Chip Form: C- or 6-shaped chips, ideal for automated production
• Surface Finish: Ground and polished cutting edge for reduced built-up edge
• Edge Preparation: T-land with honed radius for edge stability

Recommended Applications & Workpiece Materials

The CA315 grade is specifically formulated for ferrous materials in the following ranges:

• Carbon Steels: C15 to C60 (ISO C15-C60, AISI 1010–1060)
• Alloy Steels: Low to medium alloy content (< 5% total alloying elements)
• Tool Steels: Pre-hardened steels up to 350 HB
• Cast Steels: Carbon and low-alloy castings
• Forged Steels: Hot-forged and normalized components

Recommended Cutting Conditions

Start with these parameters and optimize based on machine rigidity and part configuration:

Note: Values are starting recommendations for carbon steel (< 250 HB). Reduce Vc by 15% for alloy steels and 25% for tool steels. Use coolant for continuous cutting; dry cutting acceptable for interrupted operations.

Operating Guidelines

• Tool Overhang: Minimize overhang to reduce vibration; use minimum 3× insert thickness engagement
• Insert Seat: Ensure toolholder seat is clean and undamaged; torque clamp screw to 3.5–4.5 Nm
• Coolant: 5–8% emulsion concentration recommended; aim nozzle at cutting zone at 45°
• Edge Wear Limit: Replace insert when flank wear (VB) reaches 0.3 mm or crater depth (KT) reaches 0.1 mm
• Storage: Keep inserts in original packaging; avoid temperature fluctuations above 40°C
• Safety: Always wear cut-resistant gloves when handling sharp inserts

Toolholder Compatibility

The CNMG190608 is compatible with standard ISO toolholders. Recommended holder families:

Verify holder clamp type and insert seat angle (0° for negative inserts, 11° for positive inserts) before ordering.
