With a streamlined design that promotes rapid operation and minimal noise, NK Automation's CNC machine spindles are engineered for both efficiency and durability. These spindles are compact enough to be utilized with lightweight equipment while still providing the necessary power for a variety of applications. Capable of reaching speeds up to 60,000 rpm, they offer customizable motor power tailored to specific requirements and maintain a static runout of ≤2.0μm. This makes them ideal for tasks such as CNC bangle engraving, sheet cutting, PCB drilling and routing, denture manufacturing, and mobile cover production.

Moreover, these spindles are distinguished by their superior quality and dependability, facilitating smooth operation and stable balancing. They are particularly adept at managing intricate tasks.

Exceptional Accuracy:** Dynamic precision is less than 8 μm, static precision is below 2 μm, and shaft rotation runout measures under 1 μm.
Compact Design:** Features a small size, minimal inertia, and reduced heat variations.
Balance Classification:** Rated at G0.4 with low vibration levels and minimal noise production.
Advanced Configuration:** Includes a rapid automatic tool change (ATC) system, an optional temperature sensor, and ultra-precise ceramic ball bearings.
Reliability:** Designed for low failure rates due to its precision construction, straightforward design, and ease of maintenance.
Dust and Water Resistance:** The spindle's front end utilizes a multi-layer labyrinth structure to enhance dust sealing and waterproof capabilities.
Robust Rigidity:** The built-in motor integrates the front bearing seat with the spindle, significantly enhancing overall rigidity and coaxial accuracy.
