# Industrial Specification: Pressure Roller System

## 1. Technical Definition
A mechanical system that applies controlled pressure to leather during the skiving process to ensure uniform thickness reduction.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 MPa (5-30 bar)**. Failure boundary: **4.2 MPa (42 bar) compressive stress on roller surface**, Mechanism: **Hertzian contact stress exceeding AISI 4140 steel yield strength (415 MPa) causes plastic deformation and surface spalling**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

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

### Q: What is the primary function of the pressure roller system in leather manufacturing?
**A**: The pressure roller system applies controlled, uniform pressure during the leather skiving process to ensure consistent thickness reduction across the entire material surface, improving quality and reducing waste.

### Q: What materials are used in the construction of this pressure roller system?
**A**: This system is constructed from hardened steel for structural components, chrome-plated steel for corrosion resistance on contact surfaces, and polyurethane for the pressure roller itself to provide optimal grip and pressure distribution without damaging leather.

### Q: How does the pressure adjustment mechanism work on this system?
**A**: The pressure adjustment mechanism allows operators to precisely calibrate the amount of pressure applied to the leather, typically through a calibrated dial or digital interface that controls the roller's compression force, ensuring optimal results for different leather types and thickness requirements.
