Partner with FEPO—your precision-driven ally in global machining. With over 30 years of experience, FEPO specializes in CNC spindles, tailstocks, and high-precision modules. We go beyond components—delivering integrated solutions that enhance machine performance. The advanced technologies we have developed in-house break through traditional limits, achieving sub-micron accuracy, high rigidity, and lasting stability. Widely applied across turning and grinding systems, our customizable designs bring reliable power to high-end manufacturing.
- High-Precision Structure: Spindle and housing feature sub-4 μm fits; 20 key components maintain ≤2 μm geometric tolerances for superior rigidity and stability.
- Optimized Drive Path: Screw positioned at the force center minimizes stick-slip and ensures smooth, repeatable motion.
- 1 μm Feed Control: Precision ball screw with stepper or servo motor delivers ultra-fine feed for accurate wheel dressing.
- Wide Compatibility: Supports NC/CNC surface and cylindrical grinders with dressing accuracy within 2 μm on Y and Z axes.
- Low Torque, High Sensitivity: Operates at 500±100 gf·cm torque with 0.5 μm/kg stiffness for responsive, stable dressing.
Cylindrical Roller Bearing Technology: Boosting Spindle Rigidity and Longevity
FEPO integrates NN30 series double-row cylindrical roller bearings into lathe spindles to enhance rigidity, precision, and service life.- NN30 Series bearings for Spindle: Ensures high rigidity and durability for high-speed, heavy-load turning operations.
- 80%+ Contact Verification: Blue dye inspection confirms optimal contact area for balanced load distribution.
- 1 μm Inspection Tools: In-house gauges monitor radial expansion under preload to fine-tune bearing fit.
- Precision Preload Optimization: Enhances fit accuracy, reducing thermal rise, noise, and break-in time.
- Extended Spindle Life: Optimized interface design ensures long-term stability and consistent performance.
LAPPING Bore Finishing Technology: Core for Precision ID Fit FEPO proprietary LAPPING technology enhances accuracy in tailstocks and dressing systems for high-precision motion assemblies.
- μm Bore Accuracy: Achieves <2 μm cylindricity and <4 μm clearance in Ø60–Ø100 mm bores, 200–300 mm long.
- Proven in Production: Widely applied in FEPO tailstocks and dressing modules, ensuring high rigidity and smooth motion.
- Customizable Fit Solutions: Tailstocks can be tailored to meet specific accuracy and rigidity demands.
- Multi-Machine Compatibility: Adaptable across different machine types to optimize structural fit and stability.
