Quick-Change Tool Holder for Lathe

Problem Statement

Tool changes on CNC lathes are time-consuming and require re-zeroing. Design a quick-change system that allows tool swaps in < 10 seconds while maintaining positioning repeatability of < 2µm.

Requirements

• Repeatability: ±2µm in X and Z axes
• Tool change time: < 10 seconds
• Support tools up to 25mm shank diameter
• Resist cutting forces: 5kN
• Coolant-sealed design

Constraints

• Compatible with standard CNC lathe turrets
• Hardened tool steel construction
• No pneumatic or hydraulic actuation
• Manufacturing tolerances: ±5µm or better

Deliverables

• Complete CAD assembly (STEP + native files)
• GD&T drawings for critical components
• FEA stress analysis
• Kinematic coupling analysis
• Machining and heat treatment specifications
