Introduction
In CNC precision machining, incorporating a 4th axis rotary table significantly increases your capabilities for complex contouring, indexing, as well as continuous machining operations. The Fadal 4th Axis Rotary Table VH65 is a rugged, powerful unit specifically produced for Fadal CNC machines, increasing operational accuracy and dependability, particularly after complete refurbishment with a new motor and cable.This guide discusses the Fadal VH65 features and benefits, its installation and applications, enabling informed decisions on whether or not this upgrade is worth the investment.
What Is the Fadal VH65 4th Axis Rotary Table?
The Fadal VH65 is a robust rotary table designed as an integral component of Fadal CNC working place, giving it the ability to perform an additional fourth axis of rotation (A-axis) allowing:
- Complex 3D contouring (cylindrical parts, cam profiles, helical milling)
- Precision indexing (accurate angular positioning for drilling/tapping)
- Continuous 4th-axis machining (simultaneous 4-axis movement)
Key Specifications
Feature | Specification |
| Table Size | 6.5" diameter |
| Load Capacity | Up to 65 lbs |
| Accuracy | ±30 arc-seconds |
| Drive System | Direct-drive servo motor |
| Compatibility | Fadal VMC, TRM, and compatible CNC mills |
| Rebuilt Components | New motor, cable, bearings, and seals |
Why Choose a Rebuilt VH65 with New Motor & Cable?
A fully rebuilt VH65 (with new motor and wiring) offers significant advantages over used or worn units:
1. Restored Precision & Repeatability
- New motor eliminates backlash and positioning errors.
- Fresh high-resolution encoder ensures accurate angular control (±0.008°).
2. Improved Reliability
- New cable harness prevents electrical faults due to worn wiring.
- Replaced bearings/seals reduce friction and prevent coolant ingress.
3. Enhanced Performance
- Smoother motion due to refurbished drive components.
- Faster indexing speeds compared to older, worn units.
4. Cost-Effective vs. New
- 50-60% cheaper than buying new, with similar performance.
- Extended lifespan (5+ years with proper maintenance Based on use*).
- Comes With 1 year Warranty
Installation & Setup
Pre-Installation Checklist
✔ Verify machine compatibility (Fadal VMC/TRM with 4th-axis support)
✔ Check power requirements (110V/220V, servo drive compatibility)
✔ Prepare mounting hardware (T-slots, bolts, alignment tools)
Step-by-Step Installation
- Mount the Rotary Table
- Secure to the machine table using T-bolts.
- Align parallel to X/Y axes (use dial indicator <0.001" tolerance).
- Connect Motor & Encoder Cables
- Route new cables through cable carriers.
- Plug into the 4th-axis drive amplifier.
- Power Up & Calibrate
- Home the A-axis and verify encoder feedback.
- Test jog movements and backlash compensation.
- Set Up in Control
- Enable 4th axis in Fadal parameters.
- Configure G-code commands (A-axis moves, indexing).
Top Applications of the VH65 Rotary Table
1. Aerospace & Defense
- Turbine blade profiling
- Missile component machining
2. Automotive
- Camshaft lobe milling
- Wheel hub machining
3. Medical & Dental
- Bone implant contouring
- Dental crown indexing
4. General Manufacturing
- Multi-sided parts (reduce setups)
- Cylindrical engraving
Maintenance Tips for Longevity
- Daily: Wipe down surfaces, check cable integrity.
- Monthly: Lubricate worm gear, inspect bearings.
- Annually: Re-calibrate encoder, test servo tuning.
