Gerardi FL90-7 BT30 ER11 90° ATC Angle Head for Small Tool Machining with Automatic Tool Change
Gerardi FL90-7 (ATC) BT30 ER11 90° Automatic Tool Change Angle Head
The Gerardi FL90-7 (ATC) BT30 ER11 is a high‑precision 90° automatic tool change (ATC) angle head from Gerardi (Italy), part of the Evolution Line. It enables automatic, unmanned 90° milling, drilling, and tapping on CNC machines with BT30 spindles, featuring an ER11 output for small‑shank tools (≤7 mm). Lightweight yet rigid, it delivers high speed, torque, and accuracy for multi‑axis machining.
- ATC (Automatic Tool Change): Fully automatic loading/unloading from tool magazine, no manual intervention.
- BT30 Taper Input: Standard 7:24 taper for direct compatibility with BT30 CNC spindles.
- ER11 Collet Output: Clamps tools up to φ7 mm; ideal for small‑diameter drills, end mills, taps.
- 90° Fixed Angle: Compact right‑angle design for side/face machining in tight spaces.
- Lightweight Aluminum Body: Reduces spindle load; enables high‑speed operation (up to 10,000 rpm).
- ABEC 9 Precision Bearings: Preloaded angular contact bearings for ultra‑low runout (<0.002 mm).
- Gleason Spiral Bevel Gears: Ground teeth for high torque, smooth transmission, and long life.
- Interchangeable Drive Taper: Adapts to BT/SK/CAT/HSK spindles by swapping input shaft.
- 360° Adjustable Orientation Ring: Optimizes angular position for complex setups.
- Made in Italy: 100% designed/manufactured by Gerardi SPA (40+ years of angle head expertise).
- Materials: Carbon steel, alloy steel, stainless steel, aluminum, brass, cast iron.
- Operations: 90° side milling, face milling, slotting, pocketing, drilling, tapping.
- Machines: BT30 CNC machining centers, vertical/horizontal mills, multi‑tasking machines.
- Industries: Automotive, aerospace, mold & die, medical, general precision engineering.
- Tool Shank Range: φ1–φ7 mm (ER11 collet capacity).
