✅ Key Features:
-
⚙️ High-Precision Linear Movement: Achieves tight tolerances and low backlash, suitable for precise CNC applications.
-
🔩 Heavy-Duty Construction: 20mm shaft diameter supports greater loads and torque.
-
🛠️ Pre-machined for BKBF15: Eliminates the need for custom end machining, saving setup time.
-
🧈 Smooth & Low-Friction Operation: Recirculating ball nut design ensures efficient energy transfer and quiet motion.
-
🔁 Long Service Life: Made from durable alloy steel and treated for wear resistance.
-
🔧 Plug-and-Play Compatibility: Standard sizing allows easy replacement or upgrade for most CNC machines.
🛠️ How to Use:
-
Install the Ball Screw:
-
Mount the screw onto your CNC axis or linear guide system.
-
Attach BK15 (fixed) and BF15 (floating) support units using the pre-machined ends.
-
-
Mount the Ball Nut:
-
Fix the SFU2005 ball nut to your machine’s moving gantry or platform using a nut housing or flange.
-
-
Couple the Motor:
-
Connect your stepper or servo motor using a shaft coupling on the fixed (BK15) side.
-
-
Lubrication:
-
Regularly apply high-quality grease or oil to the ball nut and screw shaft to reduce friction and increase lifespan.
-
-
Testing & Calibration:
-
Power the system, jog the axis slowly, and verify smooth, backlash-free movement. Make any mechanical or software-based alignment adjustments as needed.
-
