Chipbreaker Profile
The Z4T series incorporates a ZM-type micro-geometry chipbreaker designed for high-speed finishing. The flute profile features a variable helix design that suppresses chatter and harmonic vibration, ensuring stable machining even at elevated spindle speeds. The polished flute surface (Ra 0.05 μm) minimizes chip adhesion and facilitates smooth chip evacuation.
- Chipbreaker Type: ZM-type micro-geometry
- Flute Surface Finish: Mirror-polished (Ra ≤ 0.05 μm)
- Chip Evacuation: Optimized for dry and MQL (Minimum Quantity Lubrication) cutting
- Anti-Vibration Design: Variable pitch geometry (±2° flute spacing)
Recommended Applications & Workpiece Materials
This endmill is optimized for the following material groups and application scenarios:
| Material Group | Suitability | Notes |
|---|---|---|
| Steel | Excellent | Primary target material |
| stainless steel | Very Good | Compatible with adjusted parameters |
| titanium alloys | Good | Compatible with adjusted parameters |
Application Map by Operation
| Operation Type | Suitability | Guidelines |
|---|---|---|
| Contour Milling | Excellent | Primary application |
| Slot Milling | Good | Up to 1×D depth |
| Pocket Milling | Very Good | Recommended ramp angle 2°–5° |
| 3D Surface Milling | Excellent | High-speed finishing |
| Helical Interpolation | Good | Hole diameter ≥ 1.5× tool Ø |
| Plunge Milling | Fair | Not recommended as primary |
| Profile Milling | Excellent | Side wall finishing |
| Rib Milling | Very Good | Thin-wall applications |
Recommended Cutting Conditions
The following parameters are recommended for steel, stainless steel, titanium alloys using the R030 grade. Adjustments may be required based on machine rigidity, coolant strategy, and workpiece fixturing.
| Parameter | Recommended Range | Remarks |
|---|---|---|
| Cutting Speed (Vc) | 155-220 m/min | Start at lower value, increase gradually |
| Feed per Tooth (fz) | 0.05-0.12 mm/tooth | Reduce for finishing passes |
| Axial Depth of Cut (ap) | 0.1-0.3 × D1 | Use lower end for hard materials |
| Radial Depth of Cut (ae) | 0.1-0.5 × D1 | High-speed finishing: ae ≤ 0.2 × D1 |
| Coolant Strategy | Air blast / MQL / Flood coolant | Air blast preferred for heat-resistant alloys |
| Spindle Speed (n) | Calculated from Vc and D1 | Ensure machine max RPM ≥ calculated value |
Operating Guidelines
- Run-in Procedure: For the first 5 minutes of operation, reduce cutting speed by 20% to allow the coating to stabilize and achieve optimal adhesion to the substrate.
- Tool Overhang: Minimize tool overhang to ≤ 4× tool diameter for optimal rigidity and surface finish.
- Workpiece Preparation: Ensure workpiece is securely fixtured. Use pre-drilled entry holes for pocket milling to avoid full-width engagement.
- Tool Inspection: Inspect cutting edges under 10× magnification before and after each shift. Replace immediately if chipping exceeds 0.05 mm.
- Coolant Quality: Maintain coolant concentration at 6–8% for water-miscible fluids. Filter particles > 25 μm.
- Storage: Store in original packaging at 15–25°C, humidity < 60%. Avoid contact with corrosive agents.
