Inner diameter machining of cylinder using anti-vibration bar on CNC lathe

This is a free image of a CNC lathe machining the inner diameter of a cylinder using an anti-vibration boring bar.

For long cylinders, it’s common practice to machine from both sides with a shorter tool overhang to ensure rigidity. However, to achieve higher precision (concentricity, straightness, and dimensional accuracy) and avoid a joint mark, the entire inner diameter may be finished in a single pass from one side with a longer tool overhang.

In such cases, an anti-vibration boring bar is used to suppress chatter and vibrations that can occur during the machining process.
