Fine Internal Spring Pocket Milling Workflow

Shared by StoneyCNC
This post highlights advanced CNC milling of an internal spring feature with a 0.12mm tool path, executed using a two-flute Maykestag end mill and the EXECUTIVE Model 8 machine. The detailed images and video capture the tool’s precision as rectangular pockets are milled in an aluminum block, demonstrating the handling of complex internal features.

High-Speed Aluminum Machining
The process documents repeated tool paths to ensure optimal results, with flood coolant to evacuate chips and maintain thermal stability. Protective blue film and precise fixturing reflect practical shop-floor methods for maintaining workpiece quality during high-speed machining.

Software Application in Multi-Axis Milling
ENCY CAD/CAM software managed the 2.5x and 3x milling, as well as adaptive tool paths, supporting efficient aluminum pocketing for job shop applications.
