Summary

The Haas ST-20LY is a CNC turn-mill center designed for complete, multi-operation machining of long parts. It features integrated Y-axis and C-axis functionality for milling, drilling, tapping, and contouring operations on a single setup, with an extended bed enabling substantial Z-axis travel and part length. The 12-station BMT65 turret, live tooling, and programmable hydraulic tailstock support complex geometries and unattended production.

Key Capabilities

• Simultaneous turning and secondary milling operations with Y-axis and live tooling
• Programmable hydraulic tailstock with #4 Morse taper for supporting long workpieces
• C-axis spindle for contouring and positioning tasks
• 12-station turret compatible with BMT65 toolholders for varied tool configurations
