Grade Details - Key Grade Characteristics
The PR1535 grade is Kyocera premium PVD-coated carbide grade specifically engineered for high-precision finishing and semi-finishing of steels, stainless steels, and heat-resistant alloys. It combines an ultra-fine grain carbide substrate with a multi-layer MEGACOAT PVD coating to deliver superior wear resistance, thermal stability, and edge sharpness retention.
| Characteristic | Specification | Performance Benefit |
|---|---|---|
| Substrate Material | Ultra-Fine Grain WC-Co (0.5um grain size) | High hardness, excellent edge retention |
| Coating System | MEGACOAT Multi-Layer PVD (TiAlN-based) | Superior oxidation resistance up to 900 degrees C |
| Coating Hardness | 3,300 HV | Extreme abrasion resistance |
| Coating Thickness | 2-4 um | Optimal balance of toughness and wear resistance |
| Substrate Hardness | 92.5 HRA | High rigidity for micro-machining |
| Transverse Rupture Strength | >4,000 MPa | Resistant to chipping and fracture |
| Thermal Conductivity | 75 W/mK | Efficient heat dissipation from cutting zone |
Grade Comparison Matrix
The following table compares PR1535 with other Kyocera grades to help you select the optimal solution for your application:
| Grade | Coating | Best For | Max HRC | Speed Range | Finish Quality |
|---|---|---|---|---|---|
| PR1535 | MEGACOAT PVD | Steel, SS, HR alloys (finishing) | 55 | High | Mirror |
| PR1530 | MEGACOAT PVD | General steel machining | 50 | Medium-High | Excellent |
| PR1525 | MEGACOAT NANO | Stainless steel, Ti alloys | 45 | High | Excellent |
| PR1230 | MEGACOAT HARD | Hardened steels (>50 HRC) | 65 | Medium | Very Good |
| PR1025 | MEGACOAT | General purpose, cast iron | 45 | Medium | Good |
Chipbreaker Profile
As a 2-flute ball nose endmill, the SGM00718 features a micro-honed edge with optimized T-land geometry rather than a traditional indexable insert chipbreaker. The edge preparation is specifically designed for micro-machining applications where chip control and surface finish are critical.
| Edge Parameter | Specification | Function |
|---|---|---|
| Edge Preparation | Micro-hone (0.02-0.03 mm) | Reduces burr formation, improves finish |
| T-Land Width | 0.08-0.12 mm | Strengthens cutting edge, prevents chipping |
| T-Land Angle | 15-20 degrees | Optimal balance of sharpness and strength |
| Surface Finish (Ra) | <0.2 um | Minimizes built-up edge, improves chip flow |
| Gash Design | Deep flute with sub-groove | Breaks chips, prevents clogging in deep pockets |
Recommended Applications & Workpiece Materials
The SGM00718 is optimized for the following materials and application types:
Primary Materials: Carbon Steel, Alloy Steel, Tool Steel (up to 50 HRC), Stainless Steel, Inconel 718
- 3D Contouring & Profiling: Ideal for complex mold cavities, turbine blades, and medical implants requiring smooth surface transitions.
- High-Precision Finishing: Achieves Ra 0.2-0.4 um surface finish on pre-hardened steels and stainless steels.
- Micro-Machining: Suitable for small feature machining in electronics, watchmaking, and medical device components.
- Trochoidal Milling: Efficient slotting and pocketing with reduced radial engagement for extended tool life.
- Ramping & Helical Interpolation: Smooth entry strategies for hole-making operations.
Application Map by Operation
| Operation Type | Suitability | Recommended ae/Dc | Recommended ap/Dc | Notes |
|---|---|---|---|---|
| 3D Profiling / Contouring | Excellent | 0.05-0.15 | 0.1-0.3 | Primary application; use climb milling |
| Finishing (Side Wall) | Excellent | 0.02-0.08 | 0.5-1.0 | Low radial engagement for best finish |
| Semi-Finishing | Very Good | 0.15-0.30 | 0.5-1.0 | Moderate engagement for stock removal |
| Slotting (Full Width) | Good | 1.0 | 0.5-1.0 | Use reduced feed; not recommended for deep slots |
| Plunge Milling | Fair | 0.3-0.5 | 0.1-0.2 | Limited by 2-flute geometry; use ramping preferred |
| Trochoidal Milling | Very Good | 0.05-0.10 | 1.0-2.0 | Optimal for high-efficiency pocketing |
Recommended Cutting Conditions
The following parameters are recommended starting points for the SGM00718. Adjust based on machine rigidity, workpiece fixturing, and coolant conditions.
| Workpiece Material | Cutting Speed Vc (m/min) | Spindle Speed n (min-1) | Feed per Tooth fz (mm) | Feed Rate Vf (mm/min) | Ap max (mm) | Ae max (mm) |
|---|---|---|---|---|---|---|
| Carbon Steel (C<0.5%) | 90 | 20880 | 0.006 | 250 | 1.37 | 0.206 |
| Alloy Steel (C<0.8%) | 80 | 18560 | 0.006 | 222 | 1.37 | 0.165 |
| Stainless Steel 304/316 | 70 | 16240 | 0.005 | 155 | 1.10 | 0.137 |
| Tool Steel (30-50 HRC) | 70 | 16240 | 0.004 | 136 | 0.82 | 0.110 |
| Aluminum Alloy (6061-T6) | 220 | 51040 | 0.009 | 918 | 1.64 | 0.274 |
| Titanium Ti-6Al-4V | 60 | 13920 | 0.004 | 100 | 0.69 | 0.110 |
Note: Values are starting recommendations. Reduce speed/feed by 20-30% for unstable setups or long overhangs. Use high-pressure coolant (70+ bar) for stainless steel and titanium applications.
Operating Guidelines
- Coolant Strategy: Flood coolant is recommended for steels and stainless steels. For aluminum, compressed air or minimum quantity lubrication (MQL) may be used. High-pressure through-spindle coolant (MQL or 70+ bar) is strongly recommended for titanium and Inconel.
- Tool Overhang: Minimize overhang to 3x tool diameter or less for best stability. Use shrink-fit or hydraulic holders for maximum rigidity.
- Runout Control: Total indicated runout (TIR) should not exceed 0.005 mm at the tool tip. Verify holder and spindle runout before machining.
- Entry Strategy: Use ramping or helical interpolation for entry. Avoid direct plunge. Ramp angle should not exceed 2 degrees.
- Chip Evacuation: Ensure adequate coolant flow to evacuate chips from the cutting zone, especially in deep pocketing operations. Chip recutting will significantly reduce tool life.
- Tool Life Monitoring: Monitor flank wear (VB max = 0.1 mm) and surface finish degradation. Replace tool before catastrophic failure to protect the workpiece.
- Storage: Store in original packaging in a dry environment. Avoid contact with other tools to prevent edge damage.
Toolholder Compatibility
The SGM00718 features a 3.0 mm shank diameter (h6 tolerance) and is compatible with the following holder systems:
Compatible Holders: HSK-E25, HSK-E32, ER11, ER16, TG100, Mini-collet chucks (3mm)
- Recommended: Shrink-fit or hydraulic chucks for maximum rigidity and runout control (TIR < 0.003 mm).
- Acceptable: Precision ER collet chucks (ER11, ER16, ER20) with runout-adjustable nuts.
- Not Recommended: Weldon-style side-lock holders or standard drill chucks due to excessive runout and poor gripping force.
