- Wind turbine base plates
- Chemical processing vessels
- Marine propeller shafts
| Material Group | ISO Code | Machinability |
|---|---|---|
| Low-Carbon Steel | P1.1 – P1.3 | Excellent |
| Stainless Steel (Austenitic) | M1.0 – M2.0 | Good |
| Cast Iron (Grey) | K2.0 – K3.0 | Very Good |
| Hardened Steel (45-55 HRC) | H1.0 – H2.0 | Good (with PR1225) |
Application Map by Operation
Verified performance across standard drilling operations:
| Operation Type | Suitability | Max Depth |
|---|---|---|
| Deep Hole Drilling | Excellent | ≤ 8.0×D |
| Blind Hole | Excellent | ≤ 6.0×D |
| Through-Hole | Excellent | ≤ 10.0×D |
Recommended Cutting Conditions
Starting parameters for stable machining. Adjust based on machine rigidity and workpiece condition:
| Parameter | Recommended Range | Optimal Starting Value |
|---|---|---|
| Cutting Speed (Vc) | 50 – 90 m/min | 50 m/min |
| Feed per Revolution (fn) | 0.12 – 0.20 mm/rev | 0.12 mm/rev |
| Depth of Cut (ap) | ≤ 4.45 mm (full diameter) | 3.56 mm |
| Coolant Recommendation | Emulsion 5-8% or MQL | Internal coolant pressure ≥ 25 bar |
Operating Guidelines
Follow these best practices to maximize tool life and hole quality:
- Run-in Procedure: Reduce feed by 25% for the first 20 holes to stabilize cutting edge on large diameter tools.
- Pecking Cycle: Mandatory for depths > 2.5×D. Retract to 0.5×D after every 13.4 mm of penetration.
- Spindle Warm-up: Run spindle at 40% RPM for 3 minutes before production to ensure thermal stability on large tools.
- Tool Change Interval: Monitor flank wear (VB). Replace when VB ≥ 0.4 mm or when hole tolerance exceeds H8.
- Chip Evacuation: Ensure coolant flow rate ≥ 25 L/min for Ø8.9 mm tools to prevent chip packing in deep holes.
Toolholder Compatibility
Ensure correct holder pairing for optimal runout and repeatability:
| Holder Type | Compatible Model | Max RPM |
|---|---|---|
| Primary Recommended | KDA-S100-Ø8.9 (Heavy-Duty Steel Holder) | 8,000 RPM |
| Alternative | KDA-H100-Ø8.9 (Hydraulic Clamp Holder) | 6,500 RPM |
| Taper Specification | BT50 / HSK-A100 (depending on machine) | — |
| Clamping System | Hydraulic or Power Collet (minimum Ø10.9 mm) | — |
