CNC Compatibility Guide: Can Your Stone CNC Run a 14″ 50/60 mm Milling Wheel?
中文标题：你的石材CNC能带14寸50/60mm铣磨轮吗？兼容性指南
A 14″ silent-core diamond milling wheel is one of the most efficient tools for planing CNC tables, calibrating slabs, and back-texturing. But before you invest in a Brolangt 14″ Silent-Core Milling Wheel, you must confirm whether your CNC can actually run it. This article provides a **technical compatibility checklist** for CNC owners and programmers.
1. Spindle Interface: 50/60 mm Flange Fit
The most critical factor is whether your spindle supports 50 mm or 60 mm bore flanges. The Brolangt wheel comes with a dual-bore 50/60 mm interface, so it can fit either standard. However, tolerance and installation quality directly affect stability.
- Measure spindle nose: Verify actual flange OD with a caliper. A nominal 50 mm flange may measure 49.95 mm, which still works, but excessive clearance (>0.1 mm) risks vibration.
- Reducer rings: If your spindle is 60 mm and you plan to use a reducer to 50 mm, ensure hardened steel rings with concentricity ≤0.02 mm.
- Runout control: After mounting, use a dial indicator on the wheel rim. For a 14″ (≈356 mm) wheel, TIR ≤0.05 mm is acceptable.
- Bolt pattern & guard clearance: Confirm bolt circle matches and wheel radius clears shrouds and sensors at full Z travel.
⚙️ A wheel this size magnifies small misalignments. Always clean flange faces, torque bolts evenly, and recheck runout before production runs.
2. Coolant Delivery & Slurry Management
A 14″ milling wheel is strictly wet-use. Dry running will glaze segments and overheat the core. Proper coolant is not just “some water”—it requires sustained flow, correct jet angle, and slurry evacuation.
- Flow rate: Minimum 12–15 L/min directed at the cut zone. Lower flow risks slurry packing.
- Nozzle placement: Jets should hit the leading edge of the wheel rotation. Avoid guard shadowing.
- Slurry evacuation: Tables must have effective drains; standing slurry creates drag and segment clogging.
- Filtration: Recirculated fines accelerate pump and tool wear. Use a settlement pit or inline filter.
3. Power Requirements
A 14″ wheel removes large surface areas. Power demand depends on stone type and pass depth. Granite requires more HP than marble, while engineered quartz sits in between.
| Spindle Power | Granite | Marble | Quartzite |
|---|---|---|---|
| 7.5 HP (≈5.5 kW) | ≤0.2 mm pass | ≤0.4 mm pass | Struggles |
| 10–15 HP | 0.3–0.5 mm pass | 0.6 mm pass | ≤0.3 mm pass |
| ≥20 HP | 0.6–0.8 mm pass | 1.0 mm pass | 0.5 mm pass |
🔋 Recommendation: Minimum 10 HP for efficient use. If your CNC is weaker, expect many shallow passes, lower productivity, and more spindle load.
4. RPM & Feed Ranges
Large diameter tools have lower safe RPM ranges compared with small tooling. Exceeding the range risks resonance and segment damage.
- RPM range: 1,200–2,400 RPM typical for 14″ wheels.
- Feed rate: Start at 300–500 mm/min, then increase until spindle load stabilizes.
- Pass depth: Multiple shallow passes are always safer and produce better finish.
- Safety: Always check wheel balance and never run without coolant.
5. Bridge Saw vs CNC
Sometimes a bridge saw is a better platform for this wheel, especially if your CNC is underpowered.
| Factor | Stone CNC | Bridge Saw |
|---|---|---|
| Precision | High; programmable raster passes | Moderate; limited to straight passes |
| Power | Varies (7–20 HP) | Often 20–25 HP |
| Coolant routing | Enclosed, sometimes restricted | Simple open jets |
| Setup time | More programming required | Quick manual setup |
6. Compatibility Checklist
- ✅ Spindle supports 50 mm or 60 mm bore.
- ✅ Guard clearance for 14″ OD wheel.
- ✅ Wet-use coolant flow ≥ 12 L/min.
- ✅ Spindle HP ≥ 10 for granite calibration.
- ✅ RPM controllable between 1,200–2,400.
Must-Include Product Facts
- 14″ Silent-Core Diamond Milling Wheel
- Dual bore 50/60 mm
- Wet use only
- Designed for stone CNCs (not woodworking routers)
Programming Tips
- Break-in passes: make 2 shallow runs on scrap to condition segments.
- Raster strategy: 20–30% overlap to avoid scallop marks.
- Alternate direction between passes to balance stress.
- Check spindle load meter and adjust feed before chatter develops.
