SFG0406-01 Ultra-High-Speed Dental Milling Spindle
For Dental CAD/CAM Machines | 60,000 rpm | 40mm Diameter | 90V | Precision & Reliability
The SFG0406-01 is an ultra-compact, ultra-high-speed electric spindle engineered specifically for precision dental CAD/CAM machining centers. With its small 40mm diameter, lightweight design (1.5kg), and blistering 60,000 rpm maximum speed, it is the ideal solution for fine-detail milling, grinding, and polishing of dental materials like zirconia, PMMA, resin, and wax. Powered by a 90V single-winding asynchronous motor, it delivers reliable performance with low heat generation and minimal vibration, ensuring the exceptional surface finishes and dimensional accuracy required for crowns, bridges, veneers, and implants.
Technical Overview
This micro-spindle is purpose-built for the demanding environment of digital dental laboratories and chairside milling units. Its core design prioritizes high rotational accuracy, rapid response, and operational stability at extreme speeds. The combination of precision angular contact bearings, efficient air-cooling, and a compact form factor makes it a reliable and powerful drive unit for the next generation of dental restoration manufacturing.
Core Performance Advantages
- Ultra-High Speed for Superior Finish: Delivers a constant 60,000 rpm, enabling high-quality surface finishes on dental ceramics and composites, reducing the need for extensive manual polishing and shortening production cycles.
- Compact & Lightweight Design: With a mere 40mm diameter and 1.5kg weight, it integrates easily into multi-spindle dental machining units or compact desktop mills, minimizing inertia and allowing for rapid tool path movements.
- Precision Engineering for Accuracy: Equipped with high-precision angular contact bearings (71901 front, 71900 rear) and balanced to a high standard, ensuring minimal runout and vibration for fine-detail machining and extended tool life.
- Efficient Air Cooling System: Utilizes a clean, dry air cooling system (30 L/min), effectively managing operational heat without the risk of coolant contamination—a critical factor in the clean, dust-controlled environment of dental labs.
- Simple & Reliable Tool Clamping: Features a standard Φ4 straight-shank collet system, compatible with a wide range of miniature dental grinding and milling tools. The pneumatic tool change (0.5-0.7 MPa) ensures quick and secure tool swaps.
- Optimized for Dental Workflows: The 90V motor and 2-pole design provide quick acceleration to operating speed, supporting efficient batch processing of dental restorations with consistent results.
