# Industrial Specification: Buffing Unit

## 1. Technical Definition
A mechanical component within a finishing line that performs surface polishing operations on metal products.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 m/s belt speed, 20-100 N contact force, 0.1-0.5 mm abrasive grain size**. Failure boundary: **Belt speed exceeding 2.5 m/s causes centrifugal belt detachment, contact force exceeding 120 N induces bearing seizure, abrasive grain embedment beyond 0.8 mm depth creates surface scoring**, Mechanism: **Centrifugal force exceeding belt-tensioner adhesion strength (F_c &gt; μN), Hertzian contact stress surpassing bearing fatigue limit (σ_H &gt; 1.2 GPa), abrasive particle embedment exceeding material yield strength (σ_embed &gt; σ_y)**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.

| Symbol | Variable Definition | Localized Reference |
