1. R&D Objective
Conventional CNC lathe tools typically use triangular inserts (35° included angle, R0.2mm tip radius) that cause critical limitations:

Overcutting on complex profiles

Visible Ra0.4-0.6μm surface marks requiring extensive post-processing

Material waste exceeding 12% in jewelry manufacturing

2. Features & Advantages

Full-Radius Geometry:

＞180° continuous cutting edge eliminates tool changes

Achieves Ra0.1-0.2μm mirror finishes

Omnidirectional Machining:

Single-tool solution for ID/OD roughing, finishing, chamfering

100% elimination of mismatch marks

Hybrid Material Design:

PCD for high-speed roughing (≤S15,000 RPM)

MCD/CVD for precision finishing

3. Applications

Round/oval bangle ID/OD machining

Ring band edge finishing (±0.02mm tolerance)

High-precision chamfering (0.1-0.3mm radius)

4. Tool Lifespan

10x longer vs traditional triangular inserts

Continuous 500+ hour operation in 18K gold turning

5. Performance Validation

95% material utilization rate

Zero post-polishing required for luxury jewelry
