# Industrial Specification: Cutting Drum

## 1. Technical Definition
The rotating cylindrical component of a cold milling machine that contains cutting tools for removing pavement surfaces.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **150-450 RPM rotational speed, 20-80 kN cutting force per tool**. Failure boundary: **Material yield strength exceeded at 850 MPa stress concentration at tool mounting points, bearing temperature exceeds 120°C lubricant breakdown threshold**, Mechanism: **High-cycle fatigue from cyclic loading at tool-pavement interface exceeding material endurance limit (approximately 400 MPa for tungsten carbide), abrasive wear exceeding 0.5 mm tool flank wear land causing vibration-induced resonance**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.

- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in your cutting drums?
**A**: Our cutting drums are manufactured from high-strength alloy steel for maximum durability and wear resistance in demanding pavement removal applications.

### Q: How does the cutting drum attach to the milling machine?
**A**: The cutting drum connects to the cold milling machine via the drive shaft connection, which transfers rotational power from the machine's engine to the drum assembly.

### Q: What maintenance is required for cutting drums?
**A**: Regular inspection of cutting tools/picks for wear, checking tool holders for secure fastening, and monitoring the drum shell for structural integrity are essential maintenance practices.
