| Edge Preparation | Micro-land 0.01-0.02 mm |
| Rake Angle | 8° positive |
| Relief Angle | 12° |
| Gash Depth | 0.15 × D |
Recommended Applications & Workpiece Materials
The Kyocera 197 CEM01552 with grade PR1825 is optimized for the following applications and materials:
Primary Applications: Micro-machining of precision components, medical devices, electronics, and small-diameter mold cavities
Compatible Materials: Hardened steels up to 55 HRC, stainless steel (SUS304, SUS316), titanium alloys, and non-ferrous metals
Application Map by Operation
| Operation | Rating | Notes |
|---|---|---|
| Plunge Milling | ★★★★★ | Excellent chip breaking, minimal burr |
| Slotting | ★★★★☆ | High precision, narrow slots |
| Shouldering | ★★★★★ | Mirror surface finish achievable |
| Contour / 3D | ★★★★★ | Ideal for complex mold geometries |
Recommended Cutting Conditions
The following parameters are starting recommendations for grade PR1825. Adjust based on machine rigidity, workpiece condition, and coolant availability.
| Workpiece Material | Vc (m/min) | fz (mm/t) | ap (mm) | ae (mm) |
|---|---|---|---|---|
| Carbon Steel | 150-250 | 0.05-0.12 | 1.0-3.0 | 0.5-2.0 |
| Alloy Steel | 120-200 | 0.04-0.10 | 0.8-2.5 | 0.4-1.5 |
| Stainless Steel | 80-150 | 0.03-0.08 | 0.5-2.0 | 0.3-1.0 |
| Mold Steel | 100-180 | 0.03-0.08 | 0.5-1.5 | 0.3-1.0 |
Note: Values shown are ranges (Min. – Recommendation – Max.). Use coolant for stainless steel and titanium alloys. Dry cutting acceptable for cast iron.
Operating Guidelines
- Rigidity: Use high-precision collet chucks (ER16/ER20) with runout < 3 μm. Machine spindle must be balanced to G2.5 or better.
- Coolant: Oil mist or MQL recommended for micro-machining. Avoid flood coolant that may cause thermal shock.
- Entry Strategy: Helical ramp entry at 1-2° angle. Avoid direct plunge to prevent edge chipping.
- Chip Evacuation: Compressed air blast through spindle is preferred for micro-diameter tools to prevent chip re-cutting.
- Speed & Feed: Start at lower Vc and gradually increase. Monitor tool wear via spindle load.
Toolholder Compatibility
The following toolholder systems are recommended for the Kyocera 197 CEM01552 (2.5 mm diameter):
- ER16
- ER20
- HydroForce HSK-A63
- HydroForce BT40
- ShrinkFit HSK-A63
- ShrinkFit BT40
- Milling Chuck HSK-A63
- Milling Chuck BT40
Ensure holder runout is within manufacturer specifications for optimal tool life and surface finish.
