# Industrial Specification: Main Table

## 1. Technical Definition
The primary rotating platform in a rotary table assembly that holds and positions workpieces during machining operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-3000 NÂ·m torque, 0-100 rpm rotational speed, -20Â°C to 80Â°C ambient temperature**. Failure boundary: **Exceeding 3500 NÂ·m torque causes permanent deformation, exceeding 120 rpm induces centrifugal forces &gt; 1500 N, temperature &gt; 100Â°C reduces yield strength below 250 MPa**, Mechanism: **Plastic deformation due to exceeding yield strength (Ïƒ_y = 275 MPa for AISI 4140 steel), bearing seizure from thermal expansion exceeding 0.15 mm clearance, fatigue crack propagation at stress concentrations &gt; 0.8Ïƒ_y**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Misalignment exceeding 0.05 mm/m during installation | 8 | Accelerated bearing wear causing 0.1 mm radial play within 500 operating hours | Laser alignment system with 0.01 mm/m tolerance and real-time monitoring |
| Coolant contamination with &gt;5% abrasive particles (size &gt; 25 Î¼m) | 8 | Surface pitting and scoring reducing flatness tolerance from 0.01 mm to 0.1 mm | Multi-stage filtration system with 10 Î¼m absolute rating and conductivity monitoring |

## 3. Key Technical Parameters

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used for the Main Table in rotary table assemblies?
**A**: The Main Table is typically constructed from durable materials like Cast Iron or Steel Alloy to ensure stability, vibration dampening, and longevity under heavy machining loads.

### Q: How does the Main Table contribute to machining precision?
**A**: As the primary rotating platform, the Main Table provides a flat, rigid surface to securely hold workpieces. Its precise rotation, facilitated by the integrated bearing, allows for accurate angular positioning during operations like milling or drilling.

### Q: What are the key components (BOM) of a Main Table assembly?
**A**: The core Bill of Materials includes the Table Surface (the main platform), Mounting Holes (for securing workpieces or fixtures), and the Rotation Bearing (which enables smooth and controlled table movement).
