​Product Overview​

The ​SFG62J-C3A​ is a professional-grade 62mm-diameter electric spindle engineered to deliver exceptional surface finishes for ​High-Gloss Machines (Mirror Surface Machining)​​ and ​High-Precision Engraving & Milling Centers. Distinguished from its counterparts by its ​optimized 1.8KW power rating​ and versatile collet system, this model is purpose-built for applications where flawless surface integrity, supreme accuracy, and flexible tooling are paramount. It achieves the perfect synergy of high speed, thermal stability, and minimal vibration for impeccable results across a wider range of tool sizes.

​Key Differentiators & Advantages​

• ​Engineered for Flawless Finishes:​​ A lower 1.8KW power profile optimized for finishing operations, coupled with precision-ground components, minimizes vibration and thermal distortion, making it the ideal choice for achieving Ra<0.1μm mirror-like surfaces and intricate micro-details.
• ​Superior Dynamic Precision:​​ Features exceptional rigidity (≥86 N/μm radial, ≥43 N/μm axial) and tightly controlled runout (≤2.0μm static, ≤5.0μm dynamic), ensuring consistent tool engagement and dimensional accuracy critical for 3D engraving and fine finishing.
• ​Versatile Tooling Compatibility:​​ Offers enhanced flexibility by supporting interchangeable straight-shank collets for ​φ3.175mm, φ4mm, and φ6mm​ tool diameters. This allows operators to adapt quickly to different machining requirements without changing the spindle. The clamping system provides a secure grip with a torque of ≥200 N·cm.
• ​Optimized Thermal & Contamination Control:​​ An integrated high-efficiency water-cooling circuit (≥1.3 L/min) ensures outstanding thermal stability. The ​air seal function​ (0.2-0.7 MPa) effectively protects critical internal components from coolant and abrasive debris, guaranteeing long-term reliability.

​Detailed Technical Specifications​

​Primary Applications​
