Grade Details - Key Grade Characteristics
As an uncoated fine-grain carbide grade, KW10 offers superior edge sharpness and low cutting forces. It is the grade of choice for external grooving of aluminum alloys, copper, brass, and cast iron where surface finish quality is critical. The substrate's high transverse rupture strength resists chipping and micro-fractures under intermittent cutting conditions.
Grade Comparison Matrix
Relative performance positioning against comparable grades in the Kyocera portfolio:
| Grade | Structure | Primary Use | Material Group |
|---|---|---|---|
| KW10 | Fine-Grain Uncoated | Precision Grooving | ISO K, N, S |
| TN6020 | CVD Coated | General Turning | ISO P, M |
| TC40N | CVD Coated | Heavy Roughing | ISO P |
| PR005S | Nano PVD | High-Speed Machining | ISO P, M, K |
Chipbreaker Profile
The chipbreaker geometry on the GBA43L400040 is a full-top-profile design that extends across all three usable cutting edges. The chip control features include a primary groove for initial chip curl and a secondary wall for chip breakage. This dual-action mechanism is particularly effective when grooving ductile materials like aluminum and copper alloys.
Recommended Applications & Workpiece Materials
This insert excels in external groove machining across ISO material groups K, N, and S. Recommended workpiece materials include cast iron (FC/FCD), aluminum (A5052, A6061, A7075), copper (C11000), brass (C36000), and titanium (Ti-6Al-4V). The sharp cutting edge minimizes burr formation on groove exits, reducing secondary deburring operations.
Application Map by Operation
Operational suitability matrix for machining process planning:
| Operation Type | Suitability | Notes |
|---|---|---|
| External Grooving | Primary Application | Optimized for this operation |
| Face Grooving | Conditional | Use with appropriate toolholder |
| Cut-Off / Parting | Not Recommended | Use dedicated parting inserts |
| Profiling | Conditional | Limited to straight profiles |
| Threading | Not Recommended | Use dedicated threading inserts |
Recommended Cutting Conditions
Starting parameters for stable machining; optimize based on machine rigidity and setup:
| Workpiece Material | Cutting Speed (Vc) | Feed (f) | Depth of Cut (ap) |
|---|---|---|---|
| Gray Cast Iron (ISO K) | 107–147 m/min | 0.12–0.20 mm/rev | Up to insert width |
| Aluminum Alloy (ISO N) | 187–287 m/min | 0.12–0.24 mm/rev | Up to insert width |
| Copper / Brass (ISO N) | 137–207 m/min | 0.12–0.22 mm/rev | Up to insert width |
| Titanium Alloy (ISO S) | 67–107 m/min | 0.10–0.16 mm/rev | Up to 0.5× insert width |
Operating Guidelines
Prior to operation, inspect the insert for proper seating and clamping force. The KW10 grade performs best with sharp cutting edges; replace the insert when flank wear exceeds 0.15mm or when surface finish degrades. For deep grooving operations, employ pecking cycles to clear chips. Maintain consistent coolant flow to prevent chip recutting and extend insert life.
Toolholder Compatibility
Compatible toolholders include the Kyocera GBA grooving holder series in left-hand configuration. The holder must accommodate a 3/16" thick insert and provide adequate support for the 4.0mm cutting width. For CNC lathes with Y-axis capability, consider angled toolholders for improved chip flow. Always reference the Kyocera toolholder catalog for exact mating specifications.
