• The upgraded bearing has two significant advantages: superior durability and anti-rust performance. High speed (24000R/min) and strong power bring higher efficiency than before.
• Our CNC router spindle motor works with low noise and avoids auditory fatigue. It uses air circulation to cool the heat generated by the spindle at high speed and has a good heat dissipation effect.
• The aluminum body ensures greater power and longer life; Unlike ordinary aluminum-clad wire, the oxygen-free copper coils can ensure high-quality processing and engraving performance.
• The CNC router spindle is a built-in wire box directly connected to the wire or VFD, effectively improving the stable and smooth operation. The upgraded wrench is provided for easy handling.
• Air-cooled motors commonly applied materials such as wood, stone, metal etc Suitable for machinery manufacturing sheet metal processing guardrails factories shipyards home improvement construction and other fields
