Used VTL

Boring machines come in a large variety of sizes and styles. Boring operations on small workpieces can be carried out on a lathe while larger workpieces are machined on boring mills. Workpieces are commonly 1 to 4 metres (3 ft 3 in to 13 ft 1 in) in diameter, but can be as large as 20 m (66 ft).  Tungsten-alloy disks are sealed in the bar to counteract vibration and chatter during boring. The control systems can be computer-based, allowing for automation and increased consistency.

Various fixed cycles for boring are available in CNC controls. These are pre-programmed sub-routines that move the tool through successive passes of cut, retract, advance, cut again, retract again, return to the initial position, and so on.
