Biesse Rover Manual Nc - 500

Press M05 → Wait for spindle to decelerate (monitor on-screen RPM to 0). Step 2 – Open: Open the safety guard (magnetic interlock disables drives). Step 3 – Loosen: Use the bi-articulated manual unlock wrench (supplied with machine) to depress the collet release mechanism on the spindle nose. Step 4 – Remove: Extract current tool holder (e.g., 10mm end mill). Step 5 – Insert: Clean taper (ISO 30) with lint-free cloth. Insert new tool holder (e.g., 5mm drill). Rotate until detent engages. Step 6 – Lock: Release the wrench. Audible click confirms retention balls lock. Step 7 – Close: Close guard → Press Reset → Press M03 SXXXX to verify tool rotation. 5. Common Program Blocks (G-Code Reference for Rover NC 500) The machine interprets standard ISO G-code, though with limited memory (typically 128 KB).

Troubleshooting the Rover Manual NC 500 | Symptom | Likely Cause | Solution (Per Service Manual) | | :--- | :--- | :--- | | Spindle won't start | Guard interlock open | Close guard fully; check magnetic switch alignment (behind right pillar) | | Axis moves, no spindle rotation | VFD fault (Variable Freq. Drive) | Check LED on VFD (located in electrical cabinet behind monitor). Fault 4 = overcurrent. | | Tool holder falls out | Worn collet retention springs | Replace spring pack (Biesse part # 0490.100.056). Torque wrench calibration required. | | Emergency Stop active | E-stop button pressed or chain broken | Twist E-stop to release. Check continuity on safety relay (K11). | | Display shows "REF MISSING" | Machine lost home position | Jog away from limits → Press REF key → Wait for sequence complete. | 7. Maintenance Schedule (Preventative) | Interval | Task | Specification | | :--- | :--- | :--- | | Daily | Clean T-slot table and guideways | Remove dust with brush; vacuum chip collector | | Weekly | Lubricate ball screws (X, Y, Z) | Biesse grease L252 (3 pumps per fitting) | | Monthly | Check spindle taper for wear | Apply blue marker to tool holder; inspect contact (must be 85%+). | | Quarterly | Calibrate manual tool unlock wrench | Use Biesse calibration gauge (25 Nm ± 0.5) | | Annually | Replace X/Y bellows (if torn) | Prevents abrasive dust from destroying linear guides | 8. Important Note on "Manual NC 500" vs "Rover B 4.0" Do not confuse the Manual NC 500 (vintage, manual tool change, smaller work area) with later Biesse models like the Rover B 4.0 (ATC, 4th axis ready, B_CED controller). Many support forums incorrectly merge these. Always verify your controller type by looking for the manual tool release lever on the side of the spindle casting. End of content.

Product Overview The Biesse Rover Manual NC 500 represents a specific evolution in Biesse’s legacy of 3-axis CNC machining centers. Designed for manual tool change (as opposed to an automatic tool changer/ATC), this machine is typically aimed at small workshops, educational institutions, or prototyping departments where flexibility and low entry cost are prioritized over high-volume production.
