| Parameter | Value (mm) | Value (inch) | Engineering Significance |
|---|---|---|---|
| Inscribed Circle Diameter (IC) | 9.525 ± 0.05 | 0.375 ± 0.002 | Ensures compatibility with standard tool holders |
| Cutting Edge Length (L) | 9.67 | 0.381 | Provides stable cutting force distribution |
| Insert Thickness (S) | 3.97 ± 0.13 | 0.1562 ± 0.005 | Balances rigidity and chip flow space |
| Corner Radius (rε) | 0.4 | 0.0156 | Optimizes surface finish in finishing operations |
| Clearance Angle (αₙ) | 7° | - | Reduces flank wear and friction |
| Fixing Hole Diameter (d₁) | 4.4 | 0.1732 | Secure insert clamping for vibration resistance |
The insert features the GC 1125 grade, a PVD TiAlN (Titanium Aluminum Nitride) coated超细晶粒硬质合金 (ultra-fine grain carbide) that represents a breakthrough in cutting tool material science. This composition delivers:
The MF (Medium Finish) chip breaker geometry is specifically optimized for finishing operations with low to medium feeds. Key features include:
This design excels in producing consistent, manageable chips across a range of materials, reducing machine downtime for chip removal and improving process stability.
