Enhancing CNC Machinery with SFU 1605 Rotating Ball Nut Design

Rotating Ball Nut

In the world of CNC machinery, every component plays a crucial role in achieving optimal performance. At IT-TECH, we’re proud to introduce our innovative spinning ball nut system that aims to improve CNC machinery. In this article, we’ll explore the unique features of our spinning ball nut, where the ball nut itself spins on the gantry, while the ballscrew remains static. We’ll also discuss why this design choice is valuable, especially in larger CNC machinery.

IT-TECH’s Rotating Ball Nut: A Technical Details

Our spinning ball nut system is designed for well known SFU 1605 ballscrews. It features a 30 Teeth drive pulley made of #45 galvanised steel, accommodating an HTD 5M timing belt up to 20mm of width. The housing of the driven ball nut is made from aluminum, ensuring a lightweight yet durable design. Whole part component measures just 55x52x42mm in size and is almost the same size like standard SFU1605 ball nut housing. The smooth rotation of the ball nut is provided by two premium quality deep groove ball bearings F6805 type.

Mounting the IT-TECH spinning ball nut to the gantry plate is straightforward, requiring just four M5 bolts. This easy installation process makes our solution versatile and suitable for a wide range of CNC setups, whether you’re a DIY enthusiast or a professional CNC machinery operator.

Advantages of Spinning Ball Nut in Larger CNC Machinery

  1. Vibration Reduction: Our unique design minimizes or eliminates the whip-like vibration effect seen in traditional rotating ballscrews. With the ballscrew remaining static and the spinning ball nut doing the work, there’s no chance for it to induce unwanted vibrations, ensuring precision.
  2. Improved Accuracy: The reduced vibration leads to improved accuracy and repeatability. In larger CNC systems, even tiny vibrations can result in errors over long travel distances. IT-TECH’s spinning ball nuts help mitigate this issue, ensuring consistent and precise machining.
  3. Longer Ballscrew Lengths: Because our spinning ball nut is designed for the popular SFU 1605 ballscrew type, it becomes feasible to use longer SFU 1605 ballscrews in larger CNC machinery. This extended length allows for more extensive machining capabilities, making it possible to create larger workpieces.
  4. Energy Efficiency: IT-TECH’s spinning ball nuts often require less energy to operate compared to traditional designs, thanks to reduced friction and the elimination of vibration-induced losses. This can lead to cost savings over time.
  5. Reduced Maintenance: With fewer dynamic components, IT-TECH’s spinning ball nut systems tend to require less maintenance and have a longer service life, contributing to decreased downtime and increased productivity.
  6. Fastest Feedrate: You can achieve the highest milling feedrate using our rotating ball nut by using a larger 60-tooth drive pulley on the stepper motor. In this way you can double the maximum speed of the gantry.”

Adaptable for DIY Enthusiasts and Professional Setups

One of the most exciting aspects of IT-TECH’s spinning ball nuts is their versatility. They are suitable for professional CNC setups and can be embraced by DIY enthusiasts and custom CNC machinery builders. Whether you’re creating a small-scale DIY CNC router or setting up a professional CNC machining center, the benefits of our driven ball nut in terms of speed, reduced vibrations, and extended ballscrew lengths remain equally relevant.

The Future: IT-TECH’s Innovative Advancements

At IT-TECH, we are committed to pushing the boundaries of what’s possible in CNC technology. Currently our ballnut system design is in a testing stage. Our aim is to release our product at the end of 2023 year. For any question or suggestions please do not hesitate to contact us.
