NSK E4000
Precision Meets Power

When it comes to high-speed, high-precision machining, every detail matters. From tool rigidity to surface finish, the right spindle can be the difference between good results and exceptional ones. That’s where the NSK E4000 Series steps in—a compact yet incredibly powerful electric spindle system designed to redefine productivity on CNC lathes, robots, and specialty machines.
Unmatched Speed and Power
The E4000 isn’t shy about performance. With a maximum speed of 40,000 RPM and 1,200 W (1.60 HP) of power, it’s engineered to take on demanding applications—whether it’s milling, drilling, grinding, slitting, or deburring. Its 40 mm spindle diameter makes it both versatile and space-conscious, fitting seamlessly into a wide range of setups.
Quiet Confidence – The Brushless Advantage
At the heart of the E4000 is an ultra-quiet, high-performance brushless DC motor. This design not only reduces vibration and noise, but also delivers superior durability and efficiency. Operators will appreciate the air-cooled construction, which allows for over 5,000 hours of continuous operation without compromising accuracy.
Accuracy You Can Count On
Precision is where the E4000 truly shines. With spindle runout held within 1 μm TIR and supported by dual pairs of ceramic bearings (front and rear), you get exceptional rigidity and a consistent tool path—crucial for achieving flawless finishes on intricate components.
Smart Control and Safety
The E4000 isn’t just powerful—it’s intelligent. The control unit allows integration with CNC signals, enabling:
- Automatic spindle start/stop
- Forward/reverse control
- Real-time RPM and torque feedback
- Load monitoring
For added peace of mind, an optional safety relay can be installed to enable emergency stop functions.
Applications That Push the Limits
From aerospace components to precision medical devices, the E4000’s flexibility makes it a go-to choice for manufacturers who need both speed and accuracy. Its combination of compact design, high power, and advanced controls ensures that it can handle the most challenging micro- and macro-machining projects with ease.
The NSK E4000 Series is more than just a spindle—it’s a production powerhouse built for the future of high-precision manufacturing. If your shop demands the best in performance, control, and reliability, the E4000 is ready to deliver.
