SFG0625-62T4N High-Precision Electric Spindle
Engineered for Ultra-High Gloss & Precision Engraving Applications

Product Overview
The SFG0625-62T4N is a high-performance 62mm-diameter electric spindle meticulously engineered for High-Gloss Machines (Mirror Finishing) and High-Precision Engraving & Milling Centers. Designed to achieve and maintain exceptional surface finishes, it combines a powerful 2.5KW asynchronous motor, ultra-high 60,000 rpm speed, and superior mechanical stability. This spindle delivers the precise, vibration-free performance required for flawless mirror finishes and intricate micro-machining on metals, composites, and advanced materials.
Core Features & Advantages
- Engineered for Perfection: Specifically designed for ultimate surface quality, with minimal runout (≤1.0µm taper face, ≤3.0µm static) and low vibration (≤0.6 mm/s) to ensure flawless mirror finishes.
- High-Speed, High-Power Performance: Delivers 2.5KW of rated power with a maximum speed of 60,000 rpm (1000Hz), providing the ideal balance of cutting force and surface speed for both efficient material removal and fine finishing.
- Robust & Reliable Construction: Features a heavy-duty T11-ER11 tool holder system with a strong 600N drawbar force, ensuring secure tool clamping. Integrated water cooling (≥1.3 L/min) and an air seal function (0.2-0.7 MPa) guarantee thermal stability and protect internal components from contamination.
- Precision Integration: The critical mounting diameter is machined to a precise Φ61.9 mm with a tight tolerance, ensuring perfect alignment and rigidity when integrated into the machine tool structure.
