Recommended Cutting Conditions
The following parameters are recommended starting points for the 144 1800 with PR1535 grade. Actual values should be adjusted based on machine rigidity, workpiece fixturing, and coolant delivery.
| Workpiece Material | Vc (m/min) | fz (mm/tooth) | ap (axial) | ae (radial) |
|---|---|---|---|---|
| Carbon Steel | 120-180 | 0.08-0.15 | 0.5-1.0D | 0.1-0.3D |
| Alloy Steel | 100-150 | 0.06-0.12 | 0.3-0.8D | 0.1-0.2D |
| Stainless Steel | 80-120 | 0.05-0.10 | 0.3-0.6D | 0.1-0.2D |
| Cast Iron | 150-200 | 0.10-0.18 | 0.5-1.2D | 0.2-0.4D |
| Titanium Alloy | 50-80 | 0.04-0.08 | 0.2-0.5D | 0.05-0.15D |
Note: Vc = Cutting Speed | fz = Feed per Tooth | ap = Axial Depth of Cut | ae = Radial Depth of Cut | D = Cutter Diameter. Use coolant or MQL for optimal tool life.
Operating Guidelines
- Spindle Runout: Maintain TIR ≤ 5 µm at the tool tip for optimal performance and extended tool life.
- Tool Overhang: Minimize overhang to ≤ 4× tool diameter. Use shrink-fit or hydraulic holders for best results.
- Coolant Strategy: High-pressure through-spindle coolant (70+ bar) recommended for chip evacuation in deep cavities.
- Entry Strategy: Use ramp or helical entry at reduced feed (50% of nominal) to prevent corner chipping.
- Tool Life Monitoring: Inspect cutting edges after every 30 minutes of cutting time. Replace at first sign of coating wear or edge rounding.
- Storage: Store in original packaging at 15–25°C with <60% relative humidity. Avoid contact with other tools to prevent edge damage.
- Regrinding: Not recommended — solid carbide construction with coating makes regrinding uneconomical.
Toolholder Compatibility
The 144 1800 is compatible with the following standard toolholder systems. Select the appropriate holder based on shank diameter and application requirements:
| Toolholder Model | Taper | Collet Size | Gage Length |
