CAT-FMB sleeve milling arbors are engineered for precision and durability in demanding machining environments. Designed to meet ISO 7388 and ASME B5.50 standards, these arbors ensure high rigidity and accuracy for face milling applications. Ideal for CNC machining centers and milling machines, they support efficient tool changes and heavy cutting loads.
Core Features
Structural Design
- CAT Interface Standardization: Compatible with CAT40, CAT50, and other taper specifications, ensuring seamless integration with automatic tool change systems (ATC).
- Precision Spindle + Positioning Key: Ensures accurate circumferential positioning of the milling cutter disc, preventing slippage during operation.
- Flange Locking Mechanism: Utilizes end face hexagonal screws or hydraulic expansion to secure the cutter disc, maintaining high coaxiality (radial runout ≤ 0.02mm).
Performance Advantages
- High Rigidity: The 7:24 cone surface combined with flange bolt pre-tightening withstands heavy cutting loads, suitable for materials like cast iron and stainless steel.
- Quick Tool Change: Reduces non-processing time, enhancing productivity in mass production scenarios.
- Wide Compatibility: Supports both metric and imperial milling cutters, with adjustable axial length (±2mm) for varying processing depths.
