# Industrial Specification: Chuck / Gripper Jaws

## 1. Technical Definition
Mechanical gripping component that securely holds caps during the rotary capping process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 kN clamping force, 0.01-0.05 mm positional accuracy, 40-80°C operating temperature**. Failure boundary: **Clamping force exceeds 3.0 kN causing permanent deformation, positional accuracy degrades beyond 0.1 mm, temperature exceeds 100°C causing thermal expansion mismatch**, Mechanism: **Yield strength of hardened tool steel (AISI D2) at 1.9 GPa exceeded, wear coefficient (k) of 5×10⁻⁷ mm³/N·m for carbide-tipped surfaces, coefficient of thermal expansion mismatch (12×10⁻⁶/°C steel vs 4.5×10⁻⁶/°C carbide)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Cap diameter variation exceeding ±0.2 mm tolerance | 8 | Incomplete cap seating causing 0.3-0.5 mm height deviation | Implement adaptive force control with 10 ms response time and 0.02 mm resolution laser measurement |
| Abrasive particle contamination (silica &gt; 50 μm) in cap threads | 8 | Surface wear rate acceleration to 0.01 mm/1000 cycles, coefficient of friction increase from 0.15 to 0.35 | Install 5 μm filtration in cap feed system with magnetic separation for ferrous particles |

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

### Q: What materials are chuck/gripper jaws typically made from for capping applications?
**A**: Chuck/gripper jaws are commonly manufactured from tool steel, hardened alloy steel, or stainless steel to provide durability, wear resistance, and corrosion protection in demanding rotary capping environments.

### Q: How do chuck jaws securely hold caps during the rotary capping process?
**A**: Chuck jaws use precise mechanical gripping surfaces that apply consistent pressure to caps, preventing slippage or misalignment as they rotate through the capping station, ensuring proper seal application.

### Q: What are the main components in a chuck jaw assembly (BOM)?
**A**: A typical chuck jaw assembly consists of three main components: the jaw body (main structural piece), jaw inserts (replaceable gripping surfaces), and retention pins/screws (for secure assembly and adjustment).

## 6. Manufacturing Compliance
- ISO 12164-1:2001 (TOOL HOLDERS WITH CYLINDRICAL SHANK - PART 1: SHANKS AND LOCATION BORES)
- ANSI B5.50-1994 (CHUCKS AND CHUCK JAWS)
