Once a tunnel boring machine is below a certain depth (approximately two tunnel diameters – or 28 feet in this case), the tunneling process is almost impossible to detect, especially in soft soil. The tunnel operation is inaudible, and there is typically more surface vibration felt from a pedestrian walking nearby than from the TBM operating 30+ feet below.

Although a lathe can bore and drill, it is actually associated with turning. A drilling machine is associated with drilling, a milling machine with milling, and a boring mill with boring.
A working knowledge of a Bridgeportstyle vertical milling machine also provides a good start for operating any other style milling machine. Lathes and mills are complementary machines. While lathes rotate the workpiece and produce a cylindrical cut, milling machines move work into a rotating cutter and make a straight line cut.
Boring is one of the most common machining processes. However, not all types of boring machines can be used to create custom machined parts for the industrial sector. Whether because of the dimensions of the parts or the degree of precision required, some machines are simply not suitable.
