Grade Details - Key Grade Characteristics
The Z4S series utilizes Kyocera's proprietary ultra-fine grain carbide substrate (average grain size <0.5 μm) combined with an advanced PVD multi-layer coating. This substrate-coating combination delivers:
- Exceptional hardness: 92.5 HRA substrate hardness ensures superior wear resistance at elevated cutting temperatures
- High transverse rupture strength: >4,000 MPa provides excellent edge stability and resistance to chipping
- Thermal stability: Coating withstands continuous operating temperatures up to 900°C without degradation
- Low coefficient of friction: Reduces built-up edge formation and improves chip flow dynamics
- Chemical inertness: Resists diffusion wear when machining ferrous alloys at high speeds
Grade Comparison Matrix
| Grade / Series | Substrate | Coating | Primary Application |
|---|---|---|---|
| Z4S (This Tool) | Ultra-fine grain WC-Co | Multi-layer PVD (TiAlN+TiN) | Steel, Stainless Steel, Cast Iron |
| Z3S | Fine grain WC-Co | PVD TiAlN | Aluminum, Non-ferrous |
| Z2S | Sub-micron grain WC-Co | PVD TiSiN | Hardened Steel >50 HRC |
| Z6S | Micro-grain WC-Co | PVD DLC | Graphite, Copper, Plastics |
Chipbreaker Profile
The Z4S flute geometry features an optimized chipbreaker profile specifically designed for 4-flute endmill operation:
- Flute form: Parabolic core design with progressive rake angle variation from 5° at the center to 12° at the periphery
- Core thickness: 60% of tool diameter ensures maximum rigidity for 2.5mm cutting diameter
- Chipbreaker grooves: Precision-ground micro-grooves along the cutting edge facilitate controlled chip segmentation and evacuation
- Corner radius geometry: The 0.3mm radius profile distributes cutting forces evenly, reducing stress concentration and preventing corner chipping
- Edge preparation: Honing width of 0.01-0.02 mm provides optimal edge strength while maintaining sharpness for fine finishing
Recommended Applications & Workpiece Materials
The Z4S 2.5mm endmill is optimized for the following material groups and application scenarios:
| Material Group | Examples | Hardness Range | Machinability |
|---|---|---|---|
| Carbon Steel | C45, C50, 1045, 1050 | < 30 HRC | ★★★★★ Excellent |
| Alloy Steel | 4140, 4340, 20CrNiMo | 30-45 HRC | ★★★★☆ Very Good |
| Stainless Steel | 304, 316, 17-4PH | < 35 HRC | ★★★★☆ Very Good |
| Cast Iron | GG25, GGG40, FC250 | 180-260 HB | ★★★★★ Excellent |
| Tool Steel | H13, D2, A2 | 45-55 HRC | ★★★☆☆ Good |
| Titanium Alloy | Ti-6Al-4V, Ti-5Al-2.5Sn | < 35 HRC | ★★★☆☆ Good |
Application Map by Operation
| Operation Type | Suitability | Recommended Conditions |
|---|---|---|
| Face Milling | ✓ Recommended | ae = 0.2 × DC, ap = 0.5 × DC |
| Slotting | ✓ Suitable (ae = 1.0 × DC) | Reduce feed by 20%, ensure adequate coolant |
| Profiling / Contouring | ✓✓ Optimal | ae = 0.1-0.3 × DC, high-speed finishing |
| Pocket Milling | ✓ Recommended | Helical entry, ramp angle ≤ 2° |
| High-Feed Milling | ✗ Not Recommended | Use dedicated high-feed geometry instead |
| Trochoidal Milling | ✓✓ Optimal | ae = 0.05-0.1 × DC, full flute length engagement |
Recommended Cutting Conditions
Parameters for machining carbon and alloy steels (30-45 HRC) with external coolant:
| Parameter | Symbol | Value | Unit |
|---|---|---|---|
| Cutting Speed | Vc | 100 | m/min |
| Spindle Speed | n | 12,732 | min⁻¹ |
| Feed per Tooth | fz | 0.034 | mm |
| Feed Rate | Vf | 1,731 | mm/min |
| Axial Depth of Cut | ap | 1.25 | mm |
| Radial Depth of Cut | ae | 0.5 | mm |
Operating Guidelines
- Run-out check: Ensure tool run-out is < 0.01 mm at the tool tip. Excessive run-out reduces tool life by up to 50%.
- Coolant recommendation: Use water-soluble coolant (5-8% concentration) or oil mist for optimal chip evacuation and thermal management.
- Entry strategy: For pocketing operations, use helical ramp entry (max 2° ramp angle) or pre-drill a pilot hole to avoid full-diameter engagement.
- Chip evacuation: Ensure adequate air blast or coolant pressure to prevent chip recutting, especially in deep cavity milling.
- Speed/feed adjustment: Reduce cutting speed by 15-20% when machining stainless steel or titanium alloys. Increase feed by 10% for cast iron.
- Tool life monitoring: Inspect cutting edges after 30 minutes of operation. Replace when flank wear exceeds 0.15 mm or when burr formation increases significantly.
Toolholder Compatibility
The 2.5mm Z4S endmill requires precision toolholding for optimal performance. Recommended holder types:
| Holder Type | Shank Diameter | Run-out Capability | Application |
|---|---|---|---|
| Precision Collet Chuck (ER16/ER20) | 4.0 mm | < 0.01 mm | General milling, good versatility |
| Shrink Fit Holder | 4.0 mm | < 0.005 mm | High-speed finishing, best rigidity |
| Hydraulic Chuck | 4.0 mm | < 0.008 mm | Heavy milling, vibration damping |
| Milling Chuck (Power Chuck) | 4.0 mm | < 0.015 mm | Roughing, high torque transmission |
Packaging & Ordering Information
