Chipbreaker Profile
Standard chipbreaker for general machining
The chipbreaker geometry is specifically engineered for general turning operations. It ensures optimal chip formation, controlled chip evacuation, and reduced cutting forces. The land width and groove depth are optimized for the recommended feed and depth-of-cut ranges.
Recommended Applications & Workpiece Materials
The SNMG120408HQ with grade CA515 is recommended for the following materials:
- Carbon Steel (C<0.6%)
- Alloy Steel (HB 180-320)
- Stainless Steel (AISI 304/316)
- Cast Iron (GG25/GGG40)
- Tool Steel (Hardened <45HRC)
Application Map by Operation
| Operation Type | Suitability Rating |
|---|---|
| External Turning | ★★★★★ |
| Internal Turning | ★★★★☆ |
| Profiling | ★★★☆☆ |
| Facing | ★★★★★ |
| Semi-Finish | ★★★★★ |
Recommended Cutting Conditions
| Parameter | Recommended Range |
|---|---|
| Cutting Speed (Vc) | 180-320 m/min |
| Feed Rate (fn) | 0.08-0.22 mm/rev |
| Depth of Cut (ap) | 0.5-3.0 mm |
| Workpiece Material | Steel, Stainless Steel |
Note: Start at the lower end of the recommended range and increase gradually based on tool life and surface finish requirements. Adjustments may be needed based on machine rigidity and workpiece condition.
Operating Guidelines
Semi-finishing setup. Balanced toolholder recommended. Maximum depth of cut: 3.0mm. Suitable for continuous and light interrupted cuts.
- Always use appropriate personal protective equipment (PPE) when handling inserts
- Verify toolholder condition before insert installation
- Apply correct torque when tightening clamping screws
- Use high-quality coolant for optimal tool life and surface finish
- Monitor insert wear using flank wear criteria (VB max = 0.3mm for roughing, 0.15mm for finishing)
- Replace inserts before catastrophic failure to prevent workpiece damage
Toolholder Compatibility
The SNMG120408HQ is compatible with the following toolholder families:
SNMN, SNMG, SNMCN, MCLNR series toolholders
Ensure proper insert seat condition and use recommended clamping systems. Verify toolholder ISO compatibility (ISO 5610/ISO 5608) before operation.
