# Industrial Specification: Fleshing Cylinder

## 1. Technical Definition
A rotating cylindrical component in a fleshing machine that removes flesh, fat, and connective tissue from animal hides.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 MPa hydraulic pressure, 50-200 RPM rotational speed, 20-80°C operating temperature**. Failure boundary: **Material yield strength exceeded at 350 MPa stress, bearing seizure at 120°C, blade deflection exceeding 0.5 mm clearance**, Mechanism: **Fatigue failure from cyclic loading at 10^7 cycles (S-N curve for AISI 4140 steel), abrasive wear from hide particles (Mohs hardness 3.5-4.0), thermal expansion mismatch between cylinder (α=11.5×10^-6/°C) and shaft (α=12.2×10^-6/°C)**.

### 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**: 

### Q: What materials are best for fleshing cylinders in leather manufacturing?
**A**: High-carbon steel, tool steel, and stainless steel are optimal for fleshing cylinders due to their durability, corrosion resistance, and ability to maintain sharp cutting edges during continuous hide processing.

### Q: How does the fleshing cylinder work in a fleshing machine?
**A**: The fleshing cylinder rotates within the machine, using precisely mounted cutting blades to scrape away flesh, fat, and connective tissue from animal hides, preparing them for tanning and finishing processes.

### Q: What maintenance is required for fleshing cylinders?
**A**: Regular inspection of cutting blades for sharpness, cleaning to remove tissue buildup, lubrication of shaft/bearing assemblies, and checking cylinder balance to ensure consistent performance and prevent hide damage.

## 6. Manufacturing Compliance
- ISO 3320:2019 (FLUID POWER SYSTEMS AND COMPONENTS - CYLINDER BORES AND PISTON ROD DIAMETERS AND AREA RATIOS)
- ANSI/B93.5M-1985 (HYDRAULIC FLUID POWER - CYLINDERS - BORE AND ROD AREA RATIOS)
