# Industrial Specification: Fleshing Machine

## 1. Technical Definition
A machine used in leather processing to remove flesh, fat, and muscle tissue from the flesh side of hides or skins.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 MPa hydraulic pressure, 15-30 RPM drum speed, 40-80°C operating temperature**. Failure boundary: **Hydraulic pressure exceeding 2.5 MPa causes seal rupture, drum speed exceeding 35 RPM induces centrifugal force &gt;1500 N causing bearing seizure, temperature exceeding 90°C degrades polymer seals (Shore A hardness &lt;70)**, Mechanism: **Hydraulic system failure due to Pascal's law pressure transmission exceeding seal yield strength (EPDM rubber tensile strength &lt;15 MPa), mechanical failure from centrifugal force (F=mω²r) exceeding bearing dynamic load rating (C=12 kN for 6206 bearing), thermal degradation of seals following Arrhenius equation with activation energy 80 kJ/mol**.

### 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.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| C | Dynamic Load Rating | Engineering Constant |
| P | Equivalent Dynamic Load | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Abrasive particle contamination in hydraulic fluid (ISO 4406 code &gt;18/16/13) | 8 | Progressive wear of cylinder seals causing pressure drop below 0.4 MPa | Install dual 10μm absolute filtration with differential pressure monitoring at 0.15 MPa |
| Misalignment of drum shaft exceeding 0.05 mm/mm angular tolerance | 8 | Accelerated bearing wear generating vibration amplitude &gt;4.5 mm/s RMS | Laser alignment during installation with 0.01 mm/mm precision and quarterly alignment verification |

- **Caution**: 

### Q: What materials are used in the construction of this fleshing machine?
**A**: Our fleshing machine is built with high-carbon steel for cutting components and stainless steel for corrosion-resistant parts, ensuring durability and longevity in demanding leather processing environments.

### Q: How does the tensioning system improve fleshing efficiency?
**A**: The precision tensioning system maintains consistent hide tension during operation, allowing the fleshing cylinder to uniformly remove tissue while preventing damage to valuable leather surfaces.

### Q: What maintenance is required for the fleshing cylinder and bed knife?
**A**: Regular inspection and sharpening of the high-carbon steel fleshing cylinder and bed knife are recommended, along with proper cleaning of the waste removal chute to maintain optimal performance and hygiene.
