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.
