A  BT power mill chuck is a specialized tool holder designed for use with face milling cutters on CNC machines. It combines the features of a traditional BT facemill holder with a built-in power drive mechanism.

Key Features:

• BT Shank: Ensures precise alignment and rigidity in the BT spindle.
• Face Milling Cutter Interface: Designed to securely hold face milling cutters of various sizes and styles.
• Integrated Power Drive: A built-in motor or pneumatic actuator that provides additional torque to the cutting tool, enhancing machining performance.
• Adjustable Depth of Cut: Allows for precise control over the depth of cut during machining operations.
• Coolant Through Hole (optional): Many power mill chucks have a coolant through hole to provide internal coolant delivery to the cutting tool, improving tool life and chip evacuation.
• Balancing: High-quality power mill chucks are balanced to minimize vibrations and ensure smooth operation at high speeds.

Applications of BT Power Mill Chucks:

• Heavy-Duty Face Milling: Ideal for machining tough materials or large workpieces that require significant cutting forces.
• Deep Plunging: Can effectively cut to deep depths without chatter or tool deflection.
• High-Feed Milling: Allows for higher feed rates, increasing productivity and reducing machining time.
• Difficult-to-Machine Materials: Can be used to effectively machine materials that are challenging to cut with traditional face milling methods.

By using a BT power mill chuck, manufacturers can significantly enhance their machining capabilities, especially for demanding applications.
