Thanks to our 3000 mm long anti-vibration boring bar with an operational length of 2250 mm, we can perform internal turning on tubes up to 4500 mm long and with a diameter of 450 mm. After several processing stages, these components will become rolls dedicated to the paper processing industry 📜.
Precision internal turning allows us to achieve perfectly concentric tubes between the inside and outside, thus reducing balancing issues ⚖️ and avoiding the need to weld weights inside the tube. By not welding weights inside the tube, we avoid creating weak points in the roll 💪.
At Zenit, we have several anti-vibration boring bars, the largest being:
- 3000 mm x 250 mm with a usable turning length of 2250 mm 👨🔧 👩🔧
- 2000 mm x 150 mm with a usable turning length of 1750 mm 👨🔧 👩🔧
Advantages of Internal Turning:
- High Precision: Allows for very tight tolerances and high-quality surfaces, essential for components requiring high precision.
- Concentricity: Ensures that the tubes are perfectly concentric between the inside and outside, improving the component’s performance.
- Vibration Reduction: By using appropriate tools, such as anti-vibration boring bars, vibrations can be minimized, improving the quality of the machining and the lifespan of the tools.
- Avoids Weak Points: By not welding weights inside the tube, weak points in the roll are avoided, increasing the component’s strength and durability.
- Versatility: Can be used for a wide range of materials and applications, making it a very versatile technique.
