# Industrial Specification: Blade Holder

## 1. Technical Definition
A mechanical component designed to securely hold and position a blade within a doctoring system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 MPa clamping pressure, -20°C to 150°C temperature range**. Failure boundary: **Clamping pressure below 0.3 MPa causes blade slippage; above 3.5 MPa induces plastic deformation in holder material**, Mechanism: **Stress concentration at blade-hub interface exceeding yield strength of 4140 steel (415 MPa) due to cyclic loading at 0.1-10 Hz frequency**.

### 2.1 Analytical Physics Model
Governed by the **Frame Structural Deflection Analysis**:

> **Primary Equation**: $\delta = \frac{5 q L^4}{384 E I}$  
> **Engineering Impact**: Ensures structural stability for multi-stage machines.

| Symbol | Variable Definition | Localized Reference |

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

### Q: What materials are available for the blade holder?
**A**: Our blade holders are manufactured in stainless steel for corrosion resistance, aluminum alloy for lightweight applications, and carbon steel for high-strength requirements.

### Q: How does the blade holder secure the blade in a doctoring system?
**A**: The blade holder uses a clamping bar and adjustment bolts/screws to securely grip and precisely position the blade, ensuring consistent performance in doctoring applications.

### Q: What are the main components of the blade holder?
**A**: The blade holder consists of a holder body/base, clamping bar, and adjustment bolts/screws, designed for easy installation and precise blade positioning in machinery.
