🛠️ How to Use:
-
Mount the Ball Screw:
Align the ball screw into your CNC linear motion system. Attach the BK12 (fixed end) and BF12 (floating end) supports. -
Secure the Nut:
Fix the SFU1605 ball nut onto the moving platform or table using a nut housing or flange bracket. -
Lubrication:
Apply suitable grease or oil to the screw and nut to reduce friction and wear. -
Install Coupling:
Connect the motor shaft to the screw end using a shaft coupling compatible with your stepper/servo motor. -
Alignment & Testing:
Align the ball screw precisely to avoid wobbling or uneven movement. Test motion with small movements and calibrate as needed.
