Characteristic

Model : 3X5BT

The BT spindle gripper with M45 mechanical amplification is engineered for CNC machine centers requiring high-speed, high-force tool clamping. Designed to fit BT30, BT40, BT50, and BT60 spindles, it features internal mechanical leverage that delivers up to 2–3x higher clamping force than conventional systems within limited space.

Compatible with MAS BT tapers: BT30 / BT40 / BT50 / BT60
Threaded type: Male thread (M10–M30)
Multiple clamping angle options: 0°, 30°, 45° (α)
Compact but powerful: Up to 70kN clamping force, and 450Nm tightening torque
High strength structure with proven endurance for high-speed machining

Application Areas:

• Vertical & horizontal machining centers

• High-speed tool change spindles

• Short-travel, high-grip CNC spindles

• Automatic Tool Changers (ATC)

Operational Notes:

• Ensure spindle contour matches gripper geometry

• Grease threaded and sliding parts before use

• Avoid idle running without tool holder

• Use dynamically balanced tool holders in high RPM applications
